How to Join two diff pl/sql table ???

i have three queries
1.One Query returns office and city
2.Second Query return City - State
3.Third Query returns State and Sub region
I use three cursors and i want the output as Office -City -State -Sub region
city is the joining for 1 and 2
state is the joining for 2 and 3
I am thinking of putting into pl/sql table .if it is okay tell me by giving how u will join the two pl/sql tables and if there is any other way kindly let me know .It is urgernt and please give me the code logic so that i can proceed

First thing why are you using cursors? You can do it
using SQL.Agreed, it can all be specified in a single SQL statement.
Secondly I don't think there is some as Pl/Sql TableThere used to be something called a PL/SQL Table, but these have now, thankfully, been renamed to Associative Arrays, because that is what they are, Arrays, not tables. You can't treat Assoc. Arrays as database tables so you can't do Joins in the same way as you would with an SQL statement. To implement a join using arrays would require some (possibly recursive) loops to process each of the arrays to get the required data. This would of course be a lot slower than just using SQL on database tables.

How to join two tables

hi
how to join two tables using inner join if the first table has two primary keys and second table has 3 primary keys

Would describe type of joins in ABAP, which might differ with other joins.
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 additions not be used: NOT, 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.
Note
If the same column name occurs in several database tables in a join expression, they have to be identified in all remaining additions of the SELECT statement by using the column selector ~.
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.
ENDLOOP.

How to join two ITAB

Hai
         i have created an program using ALV and i had created two internal tables namely ITAB and ITAB1.But i wasn't unable to get an output.so i like to know how to join two ITAB in ALV.

MAhesh,
Check this ex:
ITAB1 is having fields "A","B", "C".
ITAB2 is having fields "A","D", "E".
Create i_final internal table to have all fields of 2 internal tables.
i_final is having "A","B","C","D","E".
SORT itab1 ,itab2 by A
LOOP AT ITAB1.
READ TABLE itab2 WITH KEY a = itab1-a BINARY
                                                              SEARCH.
   IF SY-SUBRC EQ 0.
     MOVE : itab1-a TO i_final-a,
                  itab1-b TO i_final-b,

How to join two similar layers together?

Hey all! Please help me out, It is a little thing to do, but I am really stocked at this. How to join two layers together?? For example two Text layers or anything. Pleas can you describe the way to do it and write (if it exist) the shortcut for it?
Now I know, that layers in AAF can't be joined, there is just a "Pre-Compose". But this function is disabled the FX colone, and I have to have it there.
In this tut http://www.videocopilot.net/tutorials/shatterize/ he joined two text layers. But with some shortcut so I don't know, how he did it.
Can anyone help me plz?

Now you need to look up precomposing in the help system. It's all explained there.
Nesting and precomping are advanced functions and require careful planning or inspired improvisation within the limits of the software. You also need to look up how the rasterization button works in its two operation modes.

How to join two open endpoints?

How to join two open endpoints?
I keep getting this error message even though the endpoints do not have this: "To join, you must select two open endpoints. If they are not the same path, they cannot be on text paths nor inside graphs, and if both of them are grouped, they must be in the same group."
I've ungrouped everything.
I've tried using the pen tool to manually join.
I've moved the endpoint, then tried joining them.
I've tried command+J.
Same message everytime.
And if I use the Pathfinder, I'll get unwanted results (i.e. a new path going right though the art)
What's going on!?

blueribb,
While uploading an AI file is unsorted, you may consider at least one option:
One is that you have at least one hidden extra Anchor Point, either on one of the paths or as stray or belonging to a third path.
You may find out by:
1) Using the Direct Selection Tool to click, not drag over, both end Anchor Point and then Cmd+J, and/or
2) Using the Direct Selection Tool to click, not drag over, each end Anchor Point by itself and then move it a bit.

How to join two pl/sql tables .,.,,Urgent pls help

Hi,
Please tell me how to join to pl/sql tables with example
thanks
asp

If your main intention is to get the common records/or getting whole records from the 2 different pl/sql arrays then , pls check this piece of code & explanation
The SQL language has long offered the ability to apply set operations (UNION, INTERSECT, and MINUS) to the result sets of queries. In Oracle Database 10g, you can now use those same high-level, very powerful operators against nested tables (and only nested tables) in your PL/SQL programs and on nested tables declared as columns inside relational tables.
Let's take a look at some of the syntax needed to do this, starting with UNION.
First, I create a schema-level nested table type:
CREATE OR REPLACE TYPE strings_nt
IS TABLE OF VARCHAR2(100);
Then I define a package and within it create and populate two nested tables of this type, each containing some of my father's and my favorite things:
CREATE OR REPLACE PACKAGE favorites_pkg
IS
my_favorites strings_nt
:= strings_nt ('CHOCOLATE'
, 'BRUSSEL SPROUTS'
, 'SPIDER ROLL'
dad_favorites strings_nt
:= strings_nt ('PICKLED HERRING
, 'POTATOES'
, 'PASTRAMI'
, 'CHOCOLATE'
PROCEDURE show_favorites (
title_in IN VARCHAR2
, favs_in IN strings_nt
END;
In this package, I also include a procedure to show the contents of a strings_nt nested table. This will come in very handy shortly.
By defining these collections in a package, outside any program, they persist (they maintain their state and values) for the duration of my session or until I change or delete them. This means that I can now write programs outside the package to manipulate the contents of those collections.
Note that this package has been simplified for the purposes of presenting collection functionality. In a production application, you should always take care to "hide" your package data, as with these collections, in the package body, and then provide procedures and functions to manage the data.
Suppose, for example, that I would like to combine these two collections into a single collection of our favorites. Prior to Oracle Database 10g, I would have to write a loop that transfers the contents of one collection to another. Now, I can rely on the MULTISET UNION operator, as shown below:
DECLARE
our_favorites
strings_nt := strings_nt ();
BEGIN
our_favorites :=
favorites_pkg.my_favorites
MULTISET UNION ---- Use INTERSECT , if you want to know common records
favorites_pkg.dad_favorites;
favorites_pkg.show_favorites (
'ME then DAD', our_favorites);
END;
The output from this script is:
ME then DAD
1 = CHOCOLATE
2 = BRUSSEL SPROUTS
3 = SPIDER ROLL
4 = PICKLED HERRING
5 = POTATOES
6 = PASTRAMI
7 = CHOCOLATE

How to join two Source tables

Hi
I am doing a POC on joing two MSSQL 2K source tables and populating into Oracle table.
I did not find the joiner operator and other transformation operators.
Can anyone help me in using them?
Thanks,
Ganesh

Hi,
First, just drag&drop the two source table in the interface.
Then, connect the two tables with eachother using your mouse while selecting the two columns that you want to use in your join.
Transformations can be found when selecting a field in your target datastore; you will see a screen appear in the 'properties-panel' of your interface-editor; here you can edit transformations.
Good luck ...

Joining java array with SQL table in a stored procedure

Hey,
I am calling a pl/sql stored procedure from a java program passing two arrays (employees) and (departments) as parameters to the procedure. Within the procedure I have stored the arrays in a table of records like this:
type t_emp_type is record (employee_id number, department_id number);
type t_emp_tbl_type is table of t_emp_type index by binary_integer;
Where all elements in employees are stored in the employee_id column and departments are stored in the department_id column. So basically I've got a table like:
l_employee_tbl t_emp_tbl_type;
Looped through the arrays and stored the data like:
for i in 1..p_employees.count loop
l_employee_tbl(i).employee_id := p_employees(i);
l_employee_tbl(i).deparment_id := p_departments(i);
end loop;
Now I would like to compare my l_employee_tbl with a SQL table in the database. Basically I would like to join my l_employee_tbl table with a SQL table named departments on department_id, returning all department_id:s that was not found in table departments.
However, it is not possible to select from a user-defined table type. I have also tried to use the table() function and to cast l_employee_tbl, but found out it can't be done with records. And I would really like to use records or some other type where define my PL/SQL data. I know that you should not mix PL/SQL and SQL but in this case I think it is more efficient to try joining these "tables". Does anyone have a solution for this or advice to try something else out? It would be most appreciated.

Basically I would like to join my l_employee_tbl table with a SQL table named departments on department_id, returning all department_id:s that was not found in table departments. Of course, not possible as the SQL engine does not support PL/SQL user defined types. PL/SQL however support user defined SQL types. Which makes SQL defined types a lot more flexible.
However, it is not possible to select from a user-defined table type. I have also tried to use the table() function and to cast l_employee_tbl, but found out it can't be done with records. Never mind SQL and PL/SQL - as a generic programming data structure principle. How do you expect being able to cast an associative array (name-value pairs) to a standard array? The two data structures are very different. So I'm puzzled in how you expect to move a non-scalar name-value pair data structure into a non-scalar value only data structure?
And I would really like to use records or some other type where define my PL/SQL data. Why exactly? If the Java or PL/SQL data structure is populated using SQL data and database data, and wanting to use that data structure in SQL, what is the point? Why pull SQL data into a client data structure at all then - surely it is far more performant and scalable to rather keep that data in the database, and do the joins/selects/filters/etc using SQL?
There is also the issue of scalability of local data structures in PL/SQL. The PL/SQL engine runs inside an Oracle server process, consuming private process memory on the server. The bigger the data structures used in PL/SQL, the more server memory needs to be allocated to that server process. This does not scale. Especially not if 10 or more such server processes are running the same PL/SQL code and each server needs to grab large chunks of server memory.
If the data from Java comes from another source (e.g. keyboard, etc), and you need a means of storing this data server-side for use by PL/SQL and SQL. There are 2 basic choices. PL/SQL arrays for smallish amounts of data - and basing these arrays preferable on SQL data types allowing the array to be used by both SQL and PL/SQL engines. If the amount of data is not smallish, then it should be stored in the SQL engine (database) as that is designed for that exact purpose. And if the data is transient, then a GTT (global temp table) structure can be used (and indexed for optimal access).
