Making select statement efficient
Can any one suggest how to make this below statement efficient? It is taking quite a long time to run, wht could be the reasons.
SELECT pbimbedae pbimversb pbimpbdnr pbimmatnr pbim~werks
pbedpdatu pbedplnmg pbed~meins
pbed~aenam
FROM pbim
INNER JOIN pbed ON pbedbdzei = pbimbdzei
INTO TABLE I_IDEMAND
WHERE pbim~werks IN wa_plantsel
AND EXISTS ( SELECT matnr FROM mara
WHERE matnr = pbim~matnr
AND lvorm = '' )
AND EXISTS ( SELECT matnr FROM marc
WHERE marcmatnr = pbimmatnr
AND marcwerks = pbimwerks
AND marc~lvorm = '' )
AND pbim~vervs = 'X'
AND pbed~plnmg > 0 .
Hi,
1. First of all the sequence of fields in select query for PBIM & PBED table should be same as database table.
2. First select the data from mara & marc the fetch data from pbim.
This should solve ur performnace problem .

SELECT statement for efficiency and readability....
Hi ppl,
I need a output exactly similer to this select statement,
SELECT A.a,
B.a,

ELSE NULL
END)

Is this the best way to get this output.... (efficiency and readability)
Thx..After further review, neither of our queries is the equivalent of his though. It appears we both overlooked the case where c.a='No1' AND no row in D. His query will omit that case but ours both includes it. And it also appears that your query is a far improved equivalent to mine.

Making a Selected state for a button
Im being really stupid, im making a simple button (ive made
the up, over, down and hit states) but i want the button to remain
selected in the hit colour not just when it is pressed but when it
is selected. Is there a way of adding a selected state??

How: making column value as column of select statement
Hi
Quickly I have searched in this forum for following solution but not able to find it.
I need to make a query in such a way that the value of one column in one table should act as a column-name of another table
Eg:-
tab1
col1,col2,*col3*,col4
tab2
col11 col22 col33 col44
row1 a b col3 d
row2 aa bb cc dd
So the query should be something like --- in row2 if the value is col3 then from tab1 I should pick the col3 in select statement (basically there will be some join in tab1 and tab2 )
Hope I am able to make u all understand my query.
regardsHi all,
Sorry for late response.Just now I checked all the replies.
Actually I tried in this way.
CREATE OR REPLACE function Proc_caption (in_tan varchar2, in_order in number)
return varchar2
is
d varchar2(100) ;
begin
SELECT col1 into d
from tab1
Where
col2 = in_tanid
AND col3 = 'Y'
AND col4 = in_order ;
return d ;
Exception
WHen No_DATA_FOund then
return 'N' ;
end ;
create or replace procedure proc_generate_view(in_tan varchar2, in_soc varchar2)
is
x varchar2(2000);
v4 varchar2(50) ;
v5 varchar2(50) ;
cnt number ;
begin
v4:= PROC_Caption (in_tan,4) ;
v5:= PROC_Caption (in_tan,5) ;
x := ' Create view v_generate as '
|| ' SELECT a , b, c, d ' ;
if v4 <> 'N' THEN
x := x || ' , ' || PROC_Caption (in_tan,4) || ' as Caption4 ' ;
end if;
if v5 <> 'N' THEN
x := x || ' , ' || PROC_Caption (in_tan,5) || ' as Caption5 ' ;
end if;
x := x || ' FROM tab2 WHERE col1 = ''' || in_socid || ''''
|| ' AND col2 = ''' || in_tan || '''' ;
select count(1) into cnt from USER_OBJECTS where OBJECT_NAME = 'V_GENERATE'
and OBJECT_TYPE = 'VIEW' ;
if cnt > 0 then
EXECUTE IMMEDIATE ' DROP view V_GENERATE' ;
END IF ;
execute immediate x ;
end ;
NOTE:- I have just renamed the table name and column names in order to make it non confedential...
I have created this successfully with actual table name and column names and able to get the result as per my requirement.

Is it possible to nest SELECT statements?
Greetings community,
Another newbie’s question it is. Looking tutorials and some posts here I’ve been advised not to pull entire table through the local network, and torture client machines’ processors and memory. It’s been said that better solution is to
pull just one part of the table.
So, imagine this: you want to make a part of your app that would allow your user to view list of orders. So you put one data grid view on the form, pull last 20 headers from the table into it and leave to user to choose one to be opened
in another form. If user doesn’t find header they want, they press page up for example and previous 20 headers are loaded into data grid view. Of course, user could filter headers list by customer, or by distribution lane (having all customers residing in
one part of the town), or whatever more, but let’s not complicate things at this moment, because I’m practically in the beginning.
I’m trying to make a stored procedure that would load penultimate 20 headers when user presses page up. So, not knowing any better, I created table variable that has the same structure as Orders table with one difference: OrderID column,
which is identity (auto incremented) in Orders table, here is simply defined as bigint not null. Community member Visakh16 warned me few months ago it’s the bad practice to put self-incrementing columns in table variables.
At this moment there’s a query on my screen, which waits to become store procedure. After boring part with table variable definition, it goes like this:
INSERT INTO @OrdersTemp SELECT TOP 40 * FROM dbo.Orders ORDER BY OrderID DESC
SELECT TOP 20 * FROM @OrdersTemp ORDER BY OrderID ASC
To put that simply, I pull last 40 headers into table variable, and then pull first 20 from there. This thing works, and I just have to replace 40 with parameter, for every page up or down.
Now I have few questions.
-Is there some better way (considering performance) to achieve that? Here is the place where I wanted to ask the question from the title of the post. I don’t know much about T-SQL, and I’m not sure about the proper syntax to nest SELECT
statements, if something like that is even possible
-Is there any better way (some built-in function) to find about the count of the rows in one table than
SELECT COUNT(OrdersID) FROM dbo.Orders
Thanks for any suggestions.Hi Erland,
Sorry for the very late reply, but I said that I would start another thread when I find more free time to dedicate it to this, so I didn’t really expected you to reply anymore. I didn’t really check here for more than a week, and I glanced
at mail accidentally.
As for the negative result I got, its measurement unit is microsecond, so it doesn’t go out of margins you had experienced.
As for the number of cores, you got me surprised there. I use express edition of SQL server. Last time I checked was SQL server 2012 express, and in specifications it said that express edition is limited to 1 processor core, 1GB of RAM
and creates up to 10GB database file. I don’t believe they changed any of those specifications. It was generous enough when they doubled size of DB file few editions ago. Still, it appears that “one processor core for express edition” statement has some gray
areas in it.
However, at this moment I’m just learning, and I just wanted some way to test how efficient my queries are. I don’t have a real biz problem to solve. I don’t expect that any real performance problem should rise in years of everyday work
of populating database. What I expect is performance impact when it comes to creating reports, but after all, I don’t think that my boss would create reports by himself. I believe that creating reports would be my task, and I will be doing it after hours,
being the only user at the moment. Or maybe I could make de-normalized copy of database that would be populated after hours to make it possible for my boss to get his reports faster by himself, as I’ve heard that was the way of making BI in older non-express
editions.
So, I do suggest that we finally close this thread for sake of other readers. I’ll start another one with this subject when I find the time to do it.
Again, thanks for being with me along this journey. -
SELECT statement comparing 2 fields in a table.
Hi,
Can someone help me out in making a efficient SELECT statement for the follwing requirement.
Say, I want to select all the records from a database table where the field, PLANT is equal to field SALESORG in the table (i.e., when both fields are equal select that record).
Thanks & regards,
SreeHello,
I think this is the answer to your question... if you explain a bit more we can formulate a query.
Subquery
Variants:
1. ( select )
2. ALL ( select )
3. ANY ( select )
4. SOME ( select )
Effect
A subquery is a SELECT statement select that occurs within a
SELECT,
OPEN CURSOR,
UPDATE, or
DELETE statement
in the WHERE clause or HAVING clause, to check whether data from database tables or views meets certain criteria.
Subqueries have a restricted syntax in comparison to the normal SELECT statement:
SELECT result FROM source [WHERE where] [GROUP BY fields] [HAVING having].
Variant 1
( select )
If the subquery returns a single value, you can use any relational operator except LIKE and BETWEEN.
Example
Selecting the flights with the most passengers:
DATA: WA TYPE SFLIGHT.
SELECT * FROM SFLIGHT
INTO WA
WHERE SEATSOCC = ( SELECT MAX( SEATSOCC ) FROM SFLIGHT ).
WRITE: / WA-CARRID, WA-CONNID, WA-FLDATE.
ENDSELECT.
Note
If you use a subquery with a relational operator instead of EXISTS, you may only specify one column in the SELECT clause. This can be either a field from the database table or an aggregate expression. Subqueries of this kind are referred to as scalar subqueries.
Variant 2
ALL ( select )
If the subquery returns several lines, each containing one value, you specify that the comparison should apply for all of the values it returns.
Example
This example shows how to use ALL. It displays a list of the customer IDs of the customer (or customers) who have made the most bookings:
DATA: ID TYPE SBOOK-CUSTOMID, CNT TYPE I.
SELECT CUSTOMID COUNT( * ) AS C FROM SBOOK
INTO (ID, CNT)
GROUP BY CUSTOMID
HAVING COUNT( * ) >=
ALL ( SELECT COUNT( * ) FROM SBOOK GROUP BY CUSTOMID ).
WRITE: / ID, CNT.
ENDSELECT.
Variant 3
ANY ( select )
Variant 4
SOME ( select )
If the subquery returns several lines each containing one value, this variant specifies that the comparison should apply to at least one of the values returned. The IN operator is the same as the combination = ANY.
&ABAP_HINT
If you use a subquery with the EXISTS operator, the expression is true if the subquery selects at least one line. You can useuse * in the SELECT clause of subqueries that use EXISTS.
Example
Selecting all flights from Frankfurt to New York between 1.1.1999 and 31.3.1999 that are not yet full:
DATA: WA_SFLIGHT TYPE SFLIGHT.
SELECT * FROM SFLIGHT AS F INTO WA_SFLIGHT
WHERE SEATSOCC < F~SEATSMAX
AND EXISTS ( SELECT * FROM SPFLI
WHERE CARRID = F~CARRID
AND CONNID = F~CONNID
AND CITYFROM = 'FRANKFURT'
AND CITYTO = 'NEW YORK' )
AND FLDATE BETWEEN '19990101' AND '19990331'.
WRITE: / WA_SFLIGHT-CARRID, WA_SFLIGHT-CONNID,
WA_SFLIGHT-FLDATE.
ENDSELECT.
Subqueries such as the one in this example, in which the WHERE clause uses fields from the main query, are known as correlated subqueries. Subqueries can be nested, and a given subquery may contain any fields from other, hierarchically-superior subqueries.
In a correlated subquery, the subquery is executed for each line r returned by the main query. In the above example, the main query finds all flights in table SFLIGHT that are not full and that have a date that meets the selection criterion. The statement then performs the subquery for each of the records returned by the main query, using the corresponding values of CARRID and CONNID, to check whether the relevant flight operates between Frankfurt and New York.

move l2gr to int_report_data-i_l2gr.
modify int_report_data.
endif.
endloop.
first Billing document (I have to check fkart = ZRTY for second billing *document..how can i write the statement)
select vbeln from vbfa into (tabvbfa-vbeln) where vbelv = int_report_data-i_l2xblnr or vbelv = int_report_data-i_l1xblnr.
select single vbeln from vbrk into tabvbrk-vbeln where vbeln = tabvbfa-vbeln and fkart = 'IV'.
if sy-subrc eq 0.
move tabvbrk-vbeln to int_report_data-i_l2vbeln.
modify int_report_data.
endif.
endselect.
Thanks in advance,
YadHi!
Which of your selects is slow? Make a SQL-trace, check which select(s) is(are) slow.
For EKBE and VBFA you are selecting first key field - in general that is fast. If your z-tables are the problem, maybe an index might help.
Instead of looping and making a lot of select singles, one select 'for all entries' can help, too.
Please analyze further and give feedback.

Regarding Logical database and select statement..
Hi
Experts.
i would like to know the diff b/w logical data base & select statement while using report.
wt is the use of logical databases in R/3. is there any advantage used in the reports.
Thanks & Regards..
Spandana.Dear Spandana,
Go through the below description of LDB. I hope you wil get a fair amount of idea.
SAP comes loaded with all the extras. Among the extras that are most helpful to IT managers are all the access routines needed to pull any business object that managers can think of out of SAP databases. However, SAP has not thought of everything where your particular applications are concerned. SAP organizes its standard database tables to service business units based on conventional business applications. Itu2019s likely your business requires something new, perhaps even something exotic. In that case, you will need to create a new database, using information from different places. Basically, you need a logical database. You need to create a virtual business data object repository consisting of a new kind of record or table that suits your purposes. In addition, the repository should be composed of information that is actually stored in a number of different locations, none of them necessarily logically associated with one another. Letu2019s take a closer look at creating logical databases.
A case for a logical database
Suppose my company manufactures widgets of the most obscure variety, and they are components of other widgets. I sell my widgets as raw material for the more sophisticated widgets built by others, but in some cases I actually partner with other manufacturers in creating yet another class of widget. Now, in my world, I consequently have customers who are also partners. I sell to them and I partner with them in manufacturing and distribution. Also, I need an application that uses both of these dual-use relationships.
Essentially, I have a customer database and a partner database. Neither contains records that are structured to contain the identifying particulars of the other. Thus, I need a hybrid database that gives me tables detailing these hybrid relationships. What can I do? I can go the long way around and write a new database, pulling information from both and creating new objects with a customized program that I write by hand. However, this process is cumbersome and contains maintenance issues. On the other hand, I can use SAPu2019s logical database facility, create my logical database in a couple of minutes, and have no maintenance issues at all.
Logical database structures
There are three defining entities in an SAP logical database. You must be clear on all three in order to create and use one.
u2022 Table structure: Your logical database includes data from specified tables in SAP. There is a hierarchy among these tables defined by their foreign keys (all known to SAP), and you are going to define a customized relationship between select tables. This structure is unique and must be defined and saved.
u2022 Data selection: You may not want or need every item in the referenced tables that contributes to your customized database. There is a selection screen that permits you to pick and choose.
u2022 Database access programming: Once youu2019ve defined your logical database, SAP will generate the access subroutines needed to pull the data in the way you want it pulled.
Creating your own logical database
ABAP/4 (Advanced Business Application Programming language, version 4) is the language created by SAP for implementation and customization of its R/3 system. ABAP/4 comes loaded with many predefined logical databases that can construct and table just about any conventional business objects you might need in any canned SAP application. However, you can also create your own logical databases to construct any custom objects you care to define, as your application requires in ABAP/4. Hereu2019s a step-by-step guide:
1. Call up transaction SLDB (or transaction SE36). The path you want is Tools | ABAP Workbench | Development | Programming Environment | Logical Databases. This screen is called Logical Database Builder.
2. Enter an appropriate name in the logical database name field. You have three options on this screen: Create, Display, and Change. Choose Create.
3. Youu2019ll be prompted for a short text description of your new logical database. Enter one. Youu2019ll then be prompted to specify a development class.
4. Now comes the fun part! You must specify a root node, or a parent table, as the basis of your logical database structure. You can now place subsequent tables under the root table as needed to assemble the data object you want. You can access this tree from this point forward, to add additional tables, by selecting that root node and following the path Edit | Node | Create. Once youu2019ve saved the structure you define in this step, the system will generate the programming necessary to access your logical database. The best part is you donu2019t have to write a single line of code.
Watch out!
The use of very large tables will degrade the performance of a logical database, so be aware of that trade-off. Remember that some tables in SAP are very complex, so they will be problematic in any user-defined logical database.
Declaring a logical database
Hereu2019s another surprising feature of logical databases: You do not assign them in your ABAP/4 Code. Instead, the system requires that you specify logical databases as attributes. So when you are creating a report, have your logical database identifier (the name you gave it) on hand when you are defining its attributes on the Program Attributes screen. The Attributes section of the screen (the lower half) will include a Logical database field, where you can declare your logical database.
Logical databases for increasing efficiency
Why else would you want to create a logical database? Consider that the logical databases already available to you begin with a root node and proceed downward from there. If the data object you wish to construct consists of items that are all below the root node, you can use an existing logical database program to extract the data, then trim away what you donu2019t want using SELECT statementsu2014or you can increase the speed of the logical database program considerably by redefining the logical database for your object and starting with a table down in the chain. Either way, youu2019ll eliminate a great deal of overhead.

b) what you're storing is a string of characters. Oracle isn't going to miraculously know that that is some expression that has to be evaluated, so why should it decide to treat it as such?
c) this poor design can lead to security issues especially around SQL injection.
d) to actually perform what you want would require you to build a dynamic SQL statement and then execute that using EXECUTE IMMEDIATE or DBMS_SQL (or for a 3rd party client, a Ref Cursor), but then there are numerous issues around doing dynamic SQL, aside from SQL injection, in that you are producing code that is not validated at compile time and can thus lead to bugs showing only at run-time and sometime only under certain conditions; the code is harder to maintain; the code can potentially be avoiding the use of bind variables, impacting on resources and performance on the database; the final query can be difficult to know just from reading the code, making further development or debugging a pain in the posterior. Essentially, dynamic SQL is considered very poor design and is 99.9% of the time used for the wrong reasons.
So, why are you trying to do this? What is the business requirement you are trying to solve? -
How to test the select statement.
Hi All,
How to test the select statement.
Is there any Oracle sqlplus or toad kind of tool to test the query.
thanks
sivaUse SQL Trace (ST05) and choose 'Explain one SQL Request'. Enter your SQL command as it should be executed in the underlying database. e.g. if the db is Oracle, the statement should be entered as:
SELECT matnr,werks,lvorm,dispo
FROM marc
WHERE mandt = :a AND
matnr = :b AND
werks = :c
In the above :a, :b and :c are place holders for the actual comparison values. You dont have to enter those values. When you choose 'Explain' button, you will find the 'Execution Plan'. The important parameter which denotes the efficiency of the SQL statement is the 'Cost'. The cost should be as low as possible. The table access should be through INDEX UNIQUE SCAN. If you get a FULL TABLE SCAN and higher cost, you need to fine-tune your statement by modifying the where clause.
If you dont know Oracle SQL statements, execute the program in trace mode and go to the trace and you will find the underlying SQL statements issued to the database.

Hi folks!!
I have a few doubts about the select statements, it may be a silly things but its useful for me.
what is difference between below statment.
1)SELECT * FROM TABLE.
2)SELECT SINGLE * FROM TABLE
3)SELECT SINGLE FROM TABLE.
Hope i will get answer,thanks in advance.
Regards
Richie..Hi,
try this and if possible use sap help.i mean place the cursor on select and press F1.
Types of select statements:
1. select * from ztxlfa1 into table it.
This is simple select statement to fetch all the data of db table into internal table it.
2. select * from ztxlfa1 into table it where lifnr between 'V2' and 'V5'.
Thisis using where condition between v2 and v5.
4. select * from ztxlfa1 where land1 = 'DE'. "row goes into default table work Area
5. select lifnr land1 from ztxlfa1
into corresponding fields of it "notice 'table' is omitted
where land1 = 'DE'.
append it.
endselect.
Now data will go into work area. and then u will add it to internal table by
append statement.
6. Table 13.2 contains a list of the various forms of select as it is used with internal tables and their relative efficiency. They are in descending order of most-to-least efficient.
Table 13.2 Various Forms of SELECT when Filling an Internal Table
Statement(s) Writes To
select into table it Body
select into corresponding fields of table it Body
select into it Header line
select into corresponding fields of it Header line
7. SELECT VBRK~VBELN
VBRK~VKORG
VBRK~FKDAT
VBRK~NETWR
VBRK~WAERK
TVKOT~VTEXT
T001~BUKRS
T001~BUTXT
INTO CORRESPONDING FIELDS OF TABLE IT_FINAL
FROM VBRK
INNER JOIN TVKOT ON VBRKVKORG = TVKOTVKORG
INNER JOIN T001 ON VBRKBUKRS = T001BUKRS
WHERE VBELN IN DOCNUM AND VBRK~FKSTO = ''
AND VBRK~FKDAT in date.
Select statement using inner joins for vbrk and t001 and tvkot table for this case based on the conditions
8. SELECT T001W~NAME1 INTO TABLE IT1_T001W
FROM T001W INNER JOIN EKPO ON T001WWERKS = EKPOWERKS
WHERE EKPO~EBELN = PURORD.
here selecting a single field into table it1_t001winner join on ekpo.
9. SELECT BUKRS LIFNR EBELN FROM EKKO INTO CORRESPONDING FIELDS OF IT_EKKO WHERE EBELN IN P_O_NO.
ENDSELECT.
SELECT BUTXT FROM T001 INTO IT_T001 FOR ALL ENTRIES IN IT_EKKO WHERE BUKRS = IT_EKKO-BUKRS.
ENDSELECT.
APPEND IT_T001.
here I am using for all entries statement with select statement. Both joins and for all entries used to fetch the data on condition but for all entries is the best one.
10. SELECT AVBELN BVTEXT AFKDAT CBUTXT ANETWR AWAERK INTO TABLE ITAB
FROM VBRK AS A
INNER JOIN TVKOT AS B ON
AVKORG EQ BVKORG
INNER JOIN T001 AS C ON
ABUKRS EQ CBUKRS
WHERE AVBELN IN BDOCU AND AFKSTO EQ ' ' AND B~SPRAS EQ
SY-LANGU
AND AFKDAT IN BDATE AND AVBELN EQ ANY ( SELECT VBELN FROM
VBRP WHERE VBRP~MATNR EQ ITEMS ).
Here we are using sub query in inner join specified in brackets.

Hi,
Can anybody explain me why HITS keyword is used with SELECT statement, whats the use of if, How to find the HINTS for a particular table.
SELECT recn, recnroot, ippers
INTO CORRESPONDING FIELDS OF TABLE <ITAB1>
FROM CCIHT_IP
FOR ALL ENTRIES IN <ITAB2>
WHERE ippers = <ITAB2>-ippers
AND valfr LE sy-datum
AND valto GE sy-datum
AND iptype = 'INJ'
%_hints db2 '&max_blocking_factor 500&&max_in_blocking_factor 500&u2019.
-RajivHi,
Complex database statements or large numbers of secondary indexes that can be very
similar make it difficult for the database optimizer and the R/3 database interface to process
most efficiently. In some database systems, you can expressly influence decisions made by
database optimizer by what are known as hints.
Ex- %_HINTS ORACLE '&SUBSTITUTE VALUES&'.
Search with HINTS in SELECT STATEMENT you will get so many ans -
Update with a select statement
hi experts,
I need some help again.. :)

and u.ip_unitid = unit_id
and ui.ip_userid = ru.nf_userid
and ui.nf_statusid = 1
and n_internal = 0
and ui.ip_userid not in (select user_id
from newsmail_recipient
where user_id = ui.ip_userid

MERGE can UPDATE existing rows, and INSERT new rows at the same time. In a MERGE statement, you give a table or a sub-query in the USING clause, and define how rows from that result set match rows in your destination table. If rows match, then you can UPDATE the matching row with values from the sub-query.
Very often, MERGE is easier to use, and perhaps more efficient, than UPDATE just for changing existing rows. That is, while MERGE can do both INSERT and UPDATE, it doesn't have to . You can tell MERGE just to do one or the other if you wish.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Since you're asking about a DML statement, such as UPDATE, the sample data will be the contents of the table(s) before the DML, and the results will be state of the changed table(s) when everything is finished.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).
