WAD: Join 2 commands

Hi,
I tried to change the scaling factor of 2 structure members with one url but it changes only one (the first) structure member with my url.
thats my command url:
SAP_BW_URL CMD='SET_VALUE_PROPERTIES' DATA_PROVIDER='DATAPROVIDER_1'
STRUCTURE_MEMBER_1='3EU5KZZ4NW5BRU0Z4YRQ3H9N0' SCALING_FACTOR='100'
CMD_1='CMD=SET_VALUE_PROPERTIES DATA_PROVIDER=DATAPROVIDER_1
STRUCTURE_MEMBER_1=405F2BL2DPK17JUL9JUYIPP8S SCALING_FACTOR=100'
Any ideas whats wrong in my command?
thanks
pascal

Hi Simon,
You can use APPEND LINES OF itab1 TO itab2, when there is no condition and the structure of the 2 internal tables are the same.
If you have to join 2 internal tables upon some condition, then Loop is necessary.without looping it is not possible.

Why can't I use the Average and Join commands in an action?

Something I do a hundred times a day is select two endpoints, average them, and join them. I tried to make an action and map it to an Fkey, but Illustrator won't allow the Average or Join commands in an action. When I tried using the Insert Menu Command, it made Illustrator crash. Finally I managed to do it without Illustrator crashing, but there is then no way to hit "OK" in the Average dialog box via the Actions palette. Why is this apparently impossible?

You have to use Actions Palette Flyout menu >> insert menu item to get those menu items reocorded.
To get action to stop crashing you need to Actions Palette Flyout menu >> Playback Options >> 1 sec or greater.
There already are keyboard commands CMD J & OPT CMD J for these. Unfotunately you cannot record for example the next menu choice step such as BOTH. A script likely could be written for this though, and you can try posting in the Illustrator scripting forum.

Inner join command is not supporting pooled table

Hi Forum,
I'm new to abap. I tried passing fields of two tables into a single table using inner join command. But one of the tables is a pooled table so the command "inner join" is not supporting that. How to pass the fields in those two tables into a single table? Kindly help me out.
Rgrds,

The selected objects cannot be joined as they are invalid objects,( Compound paths, closed paths, Text Objects, Graphs, Live Paint group). You can use Join command to connect two or more paths, paths in groups; ot to close an open path.

Hi I was trying to join two Ractangle Tool objects but getting this type of Error in illustrator cs6 :-

Please assist me asap.

Yes, I know this is an old post, but I’m trying to clean them up. Did you solve this problem, if so what was the solution?
This sound like a firewall issue. I would start by disabling the firewall and seeing if you can connect. If this works then you know where the problem is,

Beginner question: adding restrictions to JOIN command?

So I'm trying to figure out how to add restrictions to JOIN commands. I've got these two tables AGENTS(aid, aname, city) and ORDERS(ordnum, cid, aid, qty, dollars). I'm trying to display all the agent names (aname) that are associated with the particular cid values 'c003' and 'c006' (the cid column contains values c001 through c006). Here is what I tried:
SQL> SELECT aname FROM agents JOIN orders ON agents.aid = orders.aid WHERE cid='003' OR cid='006';
Now I'm totally new to SQL so this may contain an obvious error, but I thought it made sense to simply put a WHERE clause at the end to place a restriction on the selection. Help would really be appreciated because I have been trying to figure out how to do this for hours.

SQL> SELECT aname FROM agents JOIN orders ON agents.aid = orders.aid WHERE cid='003' OR cid='006';You should always format your code. Use new lines and tabs to make the different clauses and the items in each clause stand out.
For example, the query below is exactly what you posted, with a little white space added:
SELECT aname
FROM    agents
JOIN      orders          ON     agents.aid      = orders.aid
WHERE     cid = '003'
OR     cid = '006'
;When posting code, or any formatted text, on this site, type these 6 characters:
(small letters only, inside curly brackets) before and after sections of formatted text, to preserve spacing.
Now I'm totally new to SQL so this may contain an obvious error, but I thought it made sense to simply put a WHERE clause at the end to place a restriction on the selection. Help would really be appreciated because I have been trying to figure out how to do this for hours.I don't see any obvious errors. You should get all the agents who have at least one order with either cid '003' or '006'.
If there can be many orders for the same agent, then you'll get the agent's name repeated as many times as they have orders with the given cids. If that's so, but you want each aname to appear only once, then change "SELECT" at the very beginning to "SELECT DISTINCT".
Aside from the possible duplicates, the query above looks like a reasonable way to get from point A to point B. Of course, if you're starting from point X and not A, and/or you want to go to point Y rather than point B, then it's not the route you want.
So where are you, and where do you want to go?
Please post a little sample data (maybe 2 to 5 rows from each table) and the results you want to get from that data.

Inner join command

Hi Forum,
How to use Inner join command?
Please explain with an example.
Thanks,
Mahathi

Inner Join and Outer Join
The data that can be selected with a view depends primarily on whether the view implements an inner join or an outer join. With an inner join, you only get the records of the cross-product for which there is an entry in all tables used in the view. With an outer join, records are also selected for which there is no entry in some of the tables used in the view.
The set of hits determined by an inner join can therefore be a subset of the hits determined with an outer join.
Database views implement an inner join. The database therefore only provides those records for which there is an entry in all the tables used in the view. Help views and maintenance views, however, implement an outer join.
Specifying Database Tables
The FROM clause determines the database tables from which the data specified in the SELECT clause is read. You can specify either a single table or more than one table, linked using inner or outer joins. The names of database tables may be specified statically or dynamically, and you can use alias names. You can also use the FROM clause to bypass the SAP buffer and restrict the number of lines to be read from the database.
"Database table" can equally mean an ABAP Dictionary view. A view links two or more database tables in the ABAP Dictionary, providing a static join that is available systemwide. You can specify the name of a view wherever the name of a database table may occur in the FROM clause.
The FROM clause has two parts - one for specifying database tables, and one for other additions:
SELECT... FROM <tables> <options>...
In <tables>, you specify the names of database tables and define joins. <options> allows you to specify further additions that control the database access.
Specifying Database Tables Statically
To specify the name of a database table statically, use the following:
SELECT... FROM <dbtab> [AS <alias>] <options> . ..
The database table <dbtab> must exist in the ABAP Dictionary. The AS addition allows you to specify an alternative name <alias> that you can then use in the SELECT; FROM, WHERE, and GROUP BY clauses. This can eliminate ambiguity when you use more than one database table, especially when you use a single database table more than once in a join. Once you have defined an alias, you may no longer use the real name of the database table
Specifying Database Tables Dynamically
To specify the name of a database table dynamically, use the following:
SELECT... FROM (<name>) <options> . ..
The field <name> must contain the name of a database table in the ABAP Dictionary. The table name must be written in uppercase. When you specify the name of a database table dynamically, you cannot use an empty INTO clause to read all of the columns into the work area <dbtab>. It is also not possible to use alternative table names.
Specifying Two or More Database Tables as an Inner Join
In a relational database, you normally need to read data simultaneously from more than one database table into an application program. You can read from more than one table in a single SELECT statement, such that the data in the tables all has to meet the same conditions, using the following join expression:
SELECT...
FROM <tab> [INNER] JOIN <dbtab> [AS <alias>] ON <cond> <options>
where <dbtab> is a single database table and <tab> is either a table or another join expression. The database tables can be specified statically or dynamically as described above. You may also use aliases. You can enclose each join expression in parentheses. The INNER addition is optional.
A join expression links each line of <tab> with the lines in <dbtab> that meet the condition <cond>. This means that there is always one or more lines from the right-hand table that is linked to each line from the left-hand table by the join. If <dbtab> does not contain any lines that meet the condition <cond>, the line from <tab> is not included in the selection.
The syntax of the <cond> condition is like that of the WHERE clause, although individual comparisons can only be linked using AND. Furthermore, each comparison must contain a column from the right-hand table <dbtab>. It does not matter on which side of the comparison it occurs. For the column names in the comparison, you can use the same names that occur in the SELECT clause, to differentiate columns from different database tables that have the same names.
The comparisons in the condition <cond> can appear in the WHERE clause instead of the ON clause, since both clauses are applied equally to the temporary table containing all of the lines resulting from the join. However, each join must contain at least one comparison in the condition <cond>.
Specifying Two or More Database Tables as a Left Outer Join
In an inner join, a line from the left-hand database table or join is only included in the selection if there is one or more lines in the right-hand database table that meet the ON condition <cond>. The left outer join, on the other hand, reads lines from the left-hand database table or join even if there is no corresponding line in the right-hand table.
SELECT...
FROM <tab> LEFT [OUTER] JOIN <dbtab> [AS <alias>] ON <cond>
 <options>
<tab> and <dbtab> are subject to the same rules and conditions as in an inner join. The OUTER addition is optional. The tables are linked in the same way as the inner join with the one exception that all lines selected from <tab> are included in the final selection. If <dbtab> does not contain any lines that meet the condition <cond>, the system includes a single line in the selection whose columns from <dbtab> are filled with null values.
In the left outer join, more restrictions apply to the condition <cond> than in the inner join. In addition to the above restrictions:
EQ or = is the only permitted relational operator.
There must be at least one comparison between columns from <tab> and <dbtab>.
The WHERE clause may not contain any comparisons with columns from <dbtab>. All comparisons using columns from <dbtab> must appear in the condition <cond>.
Client Handling
As already mentioned, you can switch off the automatic client handling in Open SQL statements using a special addition. In the SELECT statement, the addition comes after the options in the FROM clause:
SELECT... FROM <tables> CLIENT SPECIFIED. ..
If you use this addition, you can then address the client fields in the individual clauses of the SELECT statement.
Disabling Data Buffering
If buffering is allowed for a table in the ABAP Dictionary, the SELECT statement always reads the data from the buffer in the database interface of the current application server. To read data directly from the database table instead of from the buffer, use the following:
SELECT... FROM <tables> BYPASSING BUFFER. ..
This addition guarantees that the data you read is the most up to date. However, as a rule, only data that does not change frequently should be buffered, and using the buffer where appropriate improves performance. You should therefore only use this option where really necessary.
Restricting the Number of Lines
To restrict the absolute number of lines included in the selection, use the following:
SELECT... FROM <tables> UP TO <n> ROWS. ..
If <n> is a positive integer, the system reads a maximum of <n> lines. If <n> is zero, the system reads all lines that meet the selection criteria. If you use the ORDER BY clause as well, the system reads all lines belonging to the selection, sorts them, and then places the first <n> lines in the selection set.
Examples
Specifying a database table statically:
REPORT demo_select_static_database.
DATA wa TYPE scarr.
SELECT *
INTO wa
FROM scarr UP TO 4 ROWS.
WRITE: / wa-carrid, wa-carrname.
ENDSELECT.
The output is:
The system reads four lines from the database table SCARR.
Specifying a database table dynamically:
REPORT demo_select_dynamic_database.
DATA wa TYPE scarr.
DATA name(10) TYPE c VALUE 'SCARR'.
SELECT *
INTO wa
FROM (name) CLIENT SPECIFIED
WHERE mandt = '000'.
WRITE: / wa-carrid, wa-carrname.
ENDSELECT.
A condition for the MANDT field is allowed, since the example uses the CLIENT SPECIFIED option. If NAME had contained the value scarr instead of SCARR, a runtime error would have occurred.
Inner join:
REPORT demo_select_inner_join.
DATA: BEGIN OF wa,
 carrid TYPE spfli-carrid,
 connid TYPE spfli-connid,
 fldate TYPE sflight-fldate,
 bookid TYPE sbook-bookid,
 END OF wa,
 itab LIKE SORTED TABLE OF wa
 WITH UNIQUE KEY carrid connid fldate bookid.
SELECT pcarrid pconnid ffldate bbookid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( spfli AS p
 INNER JOIN sflight AS f ON pcarrid = fcarrid AND
 pconnid = fconnid )
 INNER JOIN sbook AS b ON bcarrid = fcarrid AND
 bconnid = fconnid AND
 bfldate = ffldate )
WHERE p~cityfrom = 'FRANKFURT' AND
 p~cityto = 'NEW YORK' AND
 fseatsmax > fseatsocc.
LOOP AT itab INTO wa.
AT NEW fldate.
 WRITE: / wa-carrid, wa-connid, wa-fldate.
ENDAT.
WRITE / wa-bookid.
ENDLOOP.
This example links the columns CARRID, CONNID, FLDATE, and BOOKID of the table SPFLI, SFLIGHT, and SBOOK, and creates a list of booking numbers for all flights from Frankfurt to New York that are not fully booked. An alias name is assigned to each table.
Left outer join:
REPORT demo_select_left_outer_join.
DATA: BEGIN OF wa,
 carrid TYPE scarr-carrid,
 carrname TYPE scarr-carrname,
 connid TYPE spfli-connid,
 END OF wa,
 itab LIKE SORTED TABLE OF wa
 WITH NON-UNIQUE KEY carrid.
SELECT scarrid scarrname p~connid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM scarr AS s
 LEFT OUTER JOIN spfli AS p ON scarrid = pcarrid AND
 p~cityfrom = 'FRANKFURT'.
LOOP AT itab INTO wa.
WRITE: / wa-carrid, wa-carrname, wa-connid.
ENDLOOP.
The output might look like this:
The example links the columns CARRID, CARRNAME, and CONNID of the tables SCARR and SPFLI using the condition in the left outer join that the airline must fly from Frankfurt. All other airlines have a null value in the CONNID column in the selection.
If the left outer join is replaced with an inner join, the list looks like this:
Only lines that fulfill the ON condition are included in the selection.

MS Access Update Inner Join command conversion

I have code in a Microsoft Access Database View, that I'm trying to convert to Oracle. I tried using Oracle SQL Developer's Migration tool and it basically skipped this command.
Update Table1 INNER JOIN Table2 On Table1.COL1 = Table2.COL2 SET Table1.COL3 = 1;
I've tried a number of things including selecting all the rows with something like
select * from Table1 o inner join Table2 t on o.COL1 = t.COL2
and then trying to somehow hook it to an update command where the command gets the above results and does a Table1.COL3 = 1 on all of those rows.
However I can't get the syntax correct.
Can someone please help?
Thanks,
Jeff
BTW: The code is in a MS Access view but probably belongs in a stored procedure. It also uses a Access-only Boolean instead of 1, which may be part of the reason the command conversion failed.

maybe this?
Update Table1
   set Table1.COL3 = 1
Where Table1.col1 in (select table2.col2 from table2);
or
Update Table1
   set Table1.COL3 = 1
Where exists (select 'x'
                 from table2
                where table2.col2 = table1.col1);note: untested.

WAD BI commands on an Image

Hello everyone,
I have a WAD template with a report including several queries. These queries take an initial value for calendar year/month, so that when you try to access the report, you are taken first to a screen where you give the year/month value you wish to see, and then you are taken to the report. I also have inserted an image on this template. I am looking for the following functionality: whenever a user clicks on the image, a popup window opens in which he can change the year/month value, thus affecting many (or all) of the elements found on the report.
I know how to do this using Web Items from WAD, and the command I use when using these is called "OPEN_VARIABLE_DIALOG". But since this is a BI command, I was wondering if it was possible to assign it to the image or if there is a workaround for this. I tried simply writing the command on the "onclick" property on the image, but it did not work. Looking at the forums, I could not find much about this, except for someone who wanted to do this same thing but then replied to his own thread saying that it was working already, without giving details of how he had done this.
Any suggestions?

Display first your image on an invisible label. Once displayed you can get the size of the image and you can redimension it as you want.

When do the Ripple Delete and/or Join commands become active?

I have been using Soundtrack Pro for a while, but I have not been able to use the Ripple Delete and Joind commands. Under which conditions do these commands become available? Does the Ripple Delete command work like in FCP? I use ProTools, and I would love Soundtrack to include something like the Shuffle mode, in which removing a section on the Timeline would make the rest of the audio samples on that track move up.
Is this possible? I know this can be done on the audio editor, but sometimes editing to picture requires doing this on the Timeline.
Thanks in advance for the help!

Great tip Simon - but do you not find this a bit irritating - that you have to go through this extra process just to perform a ripple delete?
The other point here, is that if you make two cuts in a clip, and then drag over the timeslice section, even with snapping turned on, it seems easy to me to not pin-point the edit in quite the same way that you do with a simple cut. By dragging over, if you miss the edit point by a fraction, you can end up ripple deleting over the cut you intended to make.
Sadie does all this with so much more ease in my view... a lot quicker when doing very fast editing. I'm surprised that with a 'pro app' tag, apple haven't gone the extra few yards with STP. Doesn't quite cut it (in my view)

Joining two commands

Post Author: ray3280
CA Forum: Data Connectivity and SQL
I have two complex SQL queries that I've put into two different SQL Commands. One returns about 15,000 Rows and the other returns about 30,000 rows. Now I join the results of both commands on 3 different fields, so I would think my report would run pretty quick, but it does not. It seriously takes about 30min just to return 100 rows. Has anyone else encountered this issue? Could it be because commands do not set any indexes? I am not sure, this really should not take 30min just to return 100 rows.
Each command themselves run really quick, it takes about 10sec to return the results of each command.

How quickly do the joined commands run in SQL directly?i.e. why do you need two commands within Crystal? Make each an inline view, join them and select from them in one command.

Print not working in WAD

Hi
1. I have added new web item table in the template with new dataprovider 2. When i execute the template i am able to see the result in the report. when i click on the print, the report is displayed in the PDF file but the new web item table is not to be seen in he pdf.
2. Default template is not showing the title of the report. How can i get the title of the report in the template?
Thanks
Annie

Hi.
Which way you printing the page ? Via File->Print in internet explorer or via button in WAD with command EXPORT to PDF and print from PDF ?
If you using EXPORT to PDF you should add your new webitem in DataBinding web items in EXPORT command properties.
Goto properties of this button "print" -> Commands-> in data binding add your new webitem.

Joining line paths in CS5

Hi,
I am working on a line art project and trying to figure out how to join an endpoint on one path to another path. Here is pic of what I am trying to do:
http://imageshack.us/photo/my-images/862/screenshot20111215at150.png/
Is there a way to join a line to the middle of another line and keep the line styles? Right now some of my paths end abruptly in a square end, but how do I joint them together? I tried using the "join" command, but that requires 2 endpoints.

Spinky,
It seems that in this case you may give the chin/cheek paths white fills and extend the troublesome paths, keeping them underneath the others; if that is not too cheeky.

WHERE clause creating a join for two or more tables

The CS3 Dreamweaver book says that the WHERE clause can
create a join for two or more tables. The join was created, but the
data is repeating. I have searched the web and this forum and have
not found the answer.
My Master page filters the recordset by Style No and when a
customer clicks on a particular style, it sends him to the Detail
page. All the records are showing from all tables on the detail
page from the Dynamic List, except they are showing multiple times
(ex. Size table has 4 sizes and Color table has 2 colors - my Size
Drop Down list is showing 8 options and my Color Drop Down List is
showing 8 options) I have a Master Page with a recordset pointing
to a Detail Page using the same recordset.
Master page works perfectly.
Master Recordset SQL:
SELECT products.itemID, products.category, products.styleno,
products.name, products.description, products.ourprice,
products.imageTH, products.image, coloroption.color,
sizeoption.size
FROM products, coloroption, sizeoption
WHERE category = 'chefcoats' AND
products.styleno=sizeoption.styleno AND
products.styleno=coloroption.styleno
GROUP BY products.styleno
ORDER BY styleno ASC
The Detail Recordset:
SELECT products.itemID, products.category, products.styleno,
products.name, products.description, products.ourprice,
products.imageTH, products.image, sizeoption.size,
coloroption.color
FROM products, sizeoption, coloroption
WHERE itemID=colname AND products.styleno=sizeoption.styleno
AND products.styleno=coloroption.styleno
I tried using the GROUP BY on the detail page, but then it
only showed one size and color from the dynamic drop down list. I
tried changing the field name "styleno" in the other tables to be
unique, however, I was using the table identifer. I tried using the
JOIN command instead of the WHERE clause and that didn't help
either.
On the detail page, the customer is supposed to click on the
Size box and see sizes XSM - 6XL ONLY ONE TIME. and then be able to
click on the Color option and see White, Black, Red ONE TIME.
Is this possible?
Thank you for giving your time to read this.!

What are the joins are available in abap.

Hi all,
What are all the joins are avaialble in abap. Can anyone explain me with examples.
thanxs in advance
hari

Hi,
There are two types of JOINS
INNER JOINS and OUTERJOINS
In the case of INNER JOIN only the records from tables for which the JOIN condition is met are retrieved.
In the case of OUTER JOIN you will get all the fields that are there in the LEFT table irrespective of the join condition.
Syntax
... [(] {dbtab_left [AS tabalias_left]} | join
{[INNER] JOIN}|{LEFT [OUTER] JOIN}
{dbtab_right [AS tabalias_right] ON join_cond} [)] ... .
Effect
The join syntax represents a recursively nestable join expression. A join expression consists of a left-hand and a right- hand side, which are joined either by means of [INNER] JOIN or LEFT [OUTER] JOIN . Depending on the type of join, a join expression can be either an inner ( INNER) or an outer (LEFT OUTER) join. Every join expression can be enclosed in round brackets. If a join expression is used, the SELECT command circumvents SAP buffering.
On the left-hand side, either a single database table, a view dbtab_left, or a join expression join can be specified. On the right-hand side, a single database table or a view dbtab_right as well as join conditions join_cond can be specified after ON. In this way, a maximum of 24 join expressions that join 25 database tables or views with each other can be specified after FROM.
AS can be used to specify an alternative table name tabalias for each of the specified database table names or for every view. A database table or a view can occur multiple times within a join expression and, in this case, have various alternative names.
The syntax of the join conditions join_cond is the same as that of the sql_cond conditions after the addition WHERE, with the following differences:
At least one comparison must be specified after ON.
Individual comparisons may be joined using AND only.
All comparisons must contain a column in the database table or the view dbtab_right on the right-hand side as an operand.
The following language elements may not be used: BETWEEN, LIKE, IN.
No sub-queries may be used.
For outer joins, only equality comparisons (=, EQ) are possible.
If an outer join occurs after FROM, the join condition of every join expression must contain at least one comparison between columns on the left-hand and the right-hand side.
In outer joins, all comparisons that contain columns as operands in the database table or the view dbtab_right on the right-hand side must be specified in the corresponding join condition. In the WHERE condition of the same SELECT command, these columns are not allowed as operands.
Resulting set for inner join
The inner join joins the columns of every selected line on the left- hand side with the columns of all lines on the right-hand side that jointly fulfil the join_cond condition. A line in the resulting set is created for every such line on the right-hand side. The content of the column on the left-hand side may be duplicated in this case. If none of the lines on the right-hand side fulfils the join_cond condition, no line is created in the resulting set.
Resulting set for outer join
The outer join basically creates the same resulting set as the inner join, with the difference that at least one line is created in the resulting set for every selected line on the left-hand side, even if no line on the right-hand side fulfils the join_cond condition. The columns on the right-hand side that do not fulfil the join_cond condition are filled with null values.
Example
Join the columns carrname, connid, fldate of the database tables scarr, spfli and sflight by means of two inner joins. A list is created of the flights from p_cityfr to p_cityto. Alternative names are used for every table.
PARAMETERS: p_cityfr TYPE spfli-cityfrom,
p_cityto TYPE spfli-cityto.
DATA: BEGIN OF wa,
fldate TYPE sflight-fldate,
carrname TYPE scarr-carrname,
connid TYPE spfli-connid,
END OF wa.
DATA itab LIKE SORTED TABLE OF wa
WITH UNIQUE KEY fldate carrname connid.
SELECT ccarrname pconnid f~fldate
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( scarr AS c
INNER JOIN spfli AS p ON pcarrid = ccarrid
AND p~cityfrom = p_cityfr
AND p~cityto = p_cityto )
INNER JOIN sflight AS f ON fcarrid = pcarrid
AND fconnid = pconnid ).
LOOP AT itab INTO wa.
WRITE: / wa-fldate, wa-carrname, wa-connid.
ENDLOOP.
Example
Join the columns carrid, carrname and connid of the database tables scarr and spfli using an outer join. The column connid is set to the null value for all flights that do not fly from p_cityfr. This null value is then converted to the appropriate initial value when it is transferred to the assigned data object. The LOOP returns all airlines that do not fly from p_cityfr.
PARAMETERS p_cityfr TYPE spfli-cityfrom.
DATA: BEGIN OF wa,
carrid TYPE scarr-carrid,
carrname TYPE scarr-carrname,
connid TYPE spfli-connid,
END OF wa,
itab LIKE SORTED TABLE OF wa
WITH NON-UNIQUE KEY carrid.
SELECT scarrid scarrname p~connid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM scarr AS s
LEFT OUTER JOIN spfli AS p ON scarrid = pcarrid
AND p~cityfrom = p_cityfr.
LOOP AT itab INTO wa.
IF wa-connid = '0000'.
WRITE: / wa-carrid, wa-carrname.
ENDIF.

Joins are used to fetch data fast from Database tables:
Tables are joined with the proper key fields to fetch the data properly.
If there are no proper key fields between tables don't use Joins;
Important thing is that don't USE JOINS FOR CLUSTER tableslike BSEG and KONV.
Only use for Transparenmt tables.
You can also use joins for the database VIews to fetch the data.
JOINS
... FROM tabref1 [INNER] JOIN tabref2 ON cond
Effect
The data is to be selected from transparent database tables and/or views determined by tabref1 and tabref2. tabref1 and tabref2 each have the same form as in variant 1 or are themselves Join expressions. The keyword INNER does not have to be specified. The database tables or views determined by tabref1 and tabref2 must be recognized by the ABAP Dictionary.
In a relational data structure, it is quite normal for data that belongs together to be split up across several tables to help the process of standardization (see relational databases). To regroup this information into a database query, you can link tables using the join command. This formulates conditions for the columns in the tables involved. The inner join contains all combinations of lines from the database table determined by tabref1 with lines from the table determined by tabref2, whose values together meet the logical condition (join condition) specified using ON>cond.
Inner join between table 1 and table 2, where column D in both tables in the join condition is set the same:
Table 1 Table 2

Example
Output a list of all flights from Frankfurt to New York between September 10th and 20th, 2001 that are not sold out:
DATA: DATE LIKE SFLIGHT-FLDATE,
CARRID LIKE SFLIGHT-CARRID,
CONNID LIKE SFLIGHT-CONNID.
SELECT FCARRID FCONNID F~FLDATE
INTO (CARRID, CONNID, DATE)
FROM SFLIGHT AS F INNER JOIN SPFLI AS P
ON FCARRID = PCARRID AND
FCONNID = PCONNID
WHERE P~CITYFROM = 'FRANKFURT'
AND P~CITYTO = 'NEW YORK'
AND F~FLDATE BETWEEN '20010910' AND '20010920'
AND FSEATSOCC < FSEATSMAX.
WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
If there are columns with the same name in both tables, you must distinguish between them by prefixing the field descriptor with the table name or a table alias.
Note
In order to determine the result of a SELECT command where the FROM clause contains a join, the database system first creates a temporary table containing the lines that meet the ON condition. The WHERE condition is then applied to the temporary table. It does not matter in an inner join whether the condition is in the ON or WHEREclause. The following example returns the same solution as the previous one.
Example
Output of a list of all flights from Frankfurt to New York between September 10th and 20th, 2001 that are not sold out:
DATA: DATE LIKE SFLIGHT-FLDATE,
CARRID LIKE SFLIGHT-CARRID,
CONNID LIKE SFLIGHT-CONNID.
SELECT FCARRID FCONNID F~FLDATE
INTO (CARRID, CONNID, DATE)
FROM SFLIGHT AS F INNER JOIN SPFLI AS P

AND F~FLDATE BETWEEN '20010910' AND '20010920'
AND FSEATSOCC < FSEATSMAX.
WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
Note
Since not all of the database systems supported by SAP use the standard syntax for ON conditions, the syntax has been restricted. It only allows those joins that produce the same results on all of the supported database systems:
Only a table or view may appear to the right of the JOIN operator, not another join expression.
Only AND is possible in the ON condition as a logical operator.
Each comparison in the ON condition must contain a field from the right-hand table.
If an outer join occurs in the FROM clause, all the ON conditions must contain at least one "real" JOIN condition (a condition that contains a field from tabref1 amd a field from tabref2.
Note
In some cases, '*' may be specified in the SELECT clause, and an internal table or work area is entered into the INTO clause (instead of a list of fields). If so, the fields are written to the target area from left to right in the order in which the tables appear in the FROM clause, according to the structure of each table work area. There can then be gaps between table work areas if you use an Alignment Request. For this reason, you should define the target work area with reference to the types of the database tables, not simply by counting the total number of fields. For an example, see below:
Variant 3
... FROM tabref1 LEFT [OUTER] JOIN tabref2 ON cond
Effect
Selects the data from the transparent database tables and/or views specified in tabref1 and tabref2. tabref1 und tabref2 both have either the same form as in variant 1 or are themselves join expressions. The keyword OUTER can be omitted. The database tables or views specified in tabref1 and tabref2 must be recognized by the ABAP-Dictionary.
In order to determine the result of a SELECT command where the FROM clause contains a left outer join, the database system creates a temporary table containing the lines that meet the ON condition. The remaining fields from the left-hand table (tabref1) are then added to this table, and their corresponding fields from the right-hand table are filled with ZERO values. The system then applies the WHERE condition to the table.
Left outer join between table 1 and table 2 where column D in both tables set the join condition:

ENDSELECT.
If there are columns with the same name in both tables, you must distinguish between them by prefixing the field descriptor with the table name or using an alias.
Note
For the resulting set of a SELECT command with a left outer join in the FROM clause, it is generally of crucial importance whether a logical condition is in the ON or WHERE condition. Since not all of the database systems supported by SAP themselves support the standard syntax and semantics of the left outer join, the syntax has been restricted to those cases that return the same solution in all database systems:
Only a table or view may come after the JOIN operator, not another join statement.
The only logical operator allowed in the ON condition is AND.
Each comparison in the ON condition must contain a field from the right-hand table.
Comparisons in the WHERE condition must not contain a field from the right-hand table.
The ON condition must contain at least one "real" JOIN condition (a condition in which a field from tabref1 as well as from tabref2 occurs).
Note
In some cases, '*' may be specivied as the field list in the SELECT clause, and an internal table or work area is entered in the INTO clause (instead of a list of fields). If so, the fields are written to the target area from left to right in the order in which the tables appear in the llen in der FROM clause, according to the structure of each table work area. There can be gaps between the table work areas if you use an Alignment Request. For this reason, you should define the target work area with reference to the types of the database tables, as in the following example (not simply by counting the total number of fields).
Example
Example of a JOIN with more than two tables: Select all flights from Frankfurt to New York between September 10th and 20th, 2001 where there are available places, and display the name of the airline.
DATA: BEGIN OF WA,
FLIGHT TYPE SFLIGHT,
PFLI TYPE SPFLI,
CARR TYPE SCARR,
END OF WA.
SELECT * INTO WA
FROM ( SFLIGHT AS F INNER JOIN SPFLI AS P
ON FCARRID = PCARRID AND
FCONNID = PCONNID )
INNER JOIN SCARR AS C
ON FCARRID = CCARRID
WHERE P~CITYFROM = 'FRANKFURT'
AND P~CITYTO = 'NEW YORK'
AND F~FLDATE BETWEEN '20010910' AND '20010920'
AND FSEATSOCC < FSEATSMAX.
WRITE: / WA-CARR-CARRNAME, WA-FLIGHT-FLDATE, WA-FLIGHT-CARRID,
WA-FLIGHT-CONNID.
ENDSELECT.

Greyed out edit commands

I have Soundtrack (not Pro). I have split and deleted many segments of an interview (voice) recording and would like to "join" some segments back together. I've highlighted both segments but cannot get the Join command to turn black so I can execute the command.
In addition, the Ripple Cut, Ripple Delete, Crossfade, and Adjust Volume Envelope also remain greyed out no matter what I do. I would appreciate feedback.

I got an answer
