How to insert variable for table name in Select statement ?

I am creating a stored procedure which will take two table names as IN parameters. Within the procedures I would like to use the parameters in the following manner;
     SELECT count(*)
     INTO v_target_cnt
     FROM TargetTable;
TargetTable is one of the parameters passed in. When I do this however it does not recognize the parameter. I have tried assigning the parameter to a local variable and using the variable, with not luck.
Any help....thanks

Null,
What you are describing is called a LEXICAL parameter, which is allowed (preceded by an ampersand) in sql but not in pl/sql because it would not be possible to compile it. That is why you need to use Andrew's suggestion to make the sql dynamic. In older versions you would need to use DBMS_SQL which is horrible and now thankfully redundant.

How to use bind variable value for table name in select statement.

Hi everyone,
I am having tough time to use value of bind variable for table name in select statement. I tried &p37_table_name. ,
:p37_table_name or v('p37_table_name) but none worked.
Following is the sql for interactive report:
select * from v('p37_table_name') where key_loc = :P37_KEY_LOC and
to_char(inspection_dte,'mm/dd/yyyy') = :P37_INSP_DT AND :p37_column_name is not null ;
I am setting value of p37_table_name in previous page which is atm_state_day_insp.
Following is error msg:
"Query cannot be parsed, please check the syntax of your query. (ORA-00933: SQL command not properly ended) "
Any help would be higly appreciated.

Interestingly enough I always had the same impression that you had to use a function to do this but found out from someone else that all you need to do is change the radio button from Use Query-Specific Column Names and Validate Query to Use Generic Column Names (parse query at runtime only). Apex will substitute your bind variable for you at run-time (something you can't normally do in pl/sql without using dynamic sql)

Dynamically assigning table name in select statement

how can i assign the table name dynamically in Select statement?
i tried following code
create or replace procedure proc1
as
x varchar2(100);
y varchar2(10);
begin
x='UNIT_MASTER';
execute immediate 'select unit_code into y from x where
rownum=1';
dbms_output.put_line(y);
end;
the procedure is created but when i execute the procedure the
error is shown in the execute immediate statement

Do the following :
Create or replace procedure pro1 as
x varchar2(100);
y varchar2(10);
begin
x := 'UNIT_MASTER';
EXECUTE IMMEDIATE 'select unit_code from '||x||' where rownum
= 1' INTO y;

How user variable table names in select statement

Dear all,
I have three table gp1,gp2,g3. i want user variable table in sql query
for example at oracle forms have a list table showing table names gp1,gp2,gp3
at form i want user this query
select gpno from :table where gpno=120;
how i can specify table name Dynamicly in select query
Thanks

Forms_DDL is a one-way street: You can only pass DDL commands TO the database; you cannot get data back using Forms_DDL.
Exec_SQL is the Forms package that enables dynamic sql within a form. But to retrieve data, you have to make a Exec_SQL call for every column in every row. So it is not a good thing to use, either.
The ref cursor method should work. You could also retrieve the data into a record group using populate_group_with_query -- it also enables dynamic data retrieval.
But if you already know you have three distinct tables and you know their names, I would keep it simple and just write three sql select statements.

Using a Variable for Table Name with a cursor

Hello All
Is it possible to use a Parameter passed to a procedure as the table name
in a cursor selection statment. I thought the below would work but I get
a error. Does anyone have any ideas?? The Error is listed below to.
Here's the code I just complied
CREATE OR REPLACE PROCEDURE Dup_Add(NEWQATABLE IN VARCHAR2) IS
CURSOR c1 IS SELECT MUNI,PROV FROM NEWQATABLE GROUP BY MUNI, PROV;
c1rec c1%ROWTYPE;
BEGIN
OPEN c1;
LOOP
FETCH c1 INTO c1rec;
EXIT WHEN c1%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(c1rec.MUNI);
END LOOP;
CLOSE c1;
END;
Here is the errors

If you are going to have a table name or a column name as a parameter, then you have to open the cursor dynamically. The following example uses Native Dynamic SQL (NDS) to open a ref cursor dynamically. I also eliminated the group by clause, since it is intended for use with aggregate functions and you weren't using an aggregate function. Also notice that there are some other differences in terms of defining variables and fetching and so forth.

Variable as table name in update statement

Hi everyone,
I am trying to update a table whose name is based on bind variables in the form and is unknown until runtime. However, I haven't been able to find a way to do this. I'm currently trying the FORMS_DDL built-in, but no success here either. Has anyone ever done this?
DECLARE
matrix_temp_table VARCHAR2(50);
BEGIN
matrix_temp_table := 'TEMP_'||:mgmt_matrix_master.div_idkey||'_'||TO_CHAR(:mgmt_matrix_master.dept_idkey);
FORMS_DDL('UPDATE '||matrix_temp_table||' SET create_date = :mgmt_matrix_master.create_date');
END;

You're right, issuing the statement using the table name itself only works outside of FORMS_DDL. After trudging through the documentation it seems the best way to accomplish what I am trying to do is by using the EXEC_SQL package. But, once again, I cant get this to work either. It seems to me what I am trying to do is a fairly simple thing, but apparently not. I'm now trying to use this code, but the table still isn't being updated.
PROCEDURE update_matrix_temp_table IS
matrix_temp_table VARCHAR2(50);
update_connid EXEC_SQL.ConnType;
update_cursor EXEC_SQL.CursType;
ignore PLS_INTEGER;
BEGIN
matrix_temp_table := 'TEMP_'||:mgmt_matrix_master.div_idkey;
update_connid := EXEC_SQL.CURR_CONNECTION;
update_cursor := EXEC_SQL.OPEN_CURSOR(update_connid);
EXEC_SQL.PARSE(update_connid, update_cursor, 'UPDATE '||matrix_temp_table||' SET emp_no = '||:mgmt_matrix_master.emp_no);
ignore := EXEC_SQL.EXECUTE(update_connid, update_cursor);
EXEC_SQL.PARSE(update_connid, update_cursor, 'COMMIT');
ignore := EXEC_SQL.EXECUTE(update_connid, update_cursor);
EXEC_SQL.CLOSE_CURSOR(update_cursor);

How to declare variable for Table type in the ABAP Editor

Hi!
I have Table Type 'FIELDNAME_TAB' (Table of fieldnames). I want to pass the list of fieldnames to this Table Type in the ABAP Editor.
Can anyone help me in this?

You would declare the internal table like so.
data: itab type FIELDNAME_TAB.
data: wa like line of itab.
wa = 'This_value'.
append wa to itab.

i have simillar insert:

and this one statement work correctly

Do NOT use "execute immediate". What is the reason for trying it this way?
If the column update_date is of type date, then you have a bug in the code, as you are trying to insert a string. If it is not a date data type, then you have a bug, because it is not of type date.
What is the outcome of:
INSERT INTO aTABLETKA_HISTORY (update_id, update_type, update_date,
      old_db_version, description, patch_number)
   values (m_id(v_rec), m_package(v_rec), to_date('07-NOV-2007', 'dd-MON-yyyy'),

Using variables as table names. Ideas for alternative designs

Hi,
I am designing an application which uses synonyms to pull information from 'client' DBs via DB Links. The synonyms are created with a DB_ID in the name (example: CUSTOMER_100, CUSTOMER_200... where 100 and 200 are DB IDs from 2 separate client DBs.
I have a procedure which selects data from the synonym based on what DB_ID is passed to the procedure. I want to be able to run this one procedure for any DB_ID that is entered. I am now aware I cannot use variable names for table names and using EXECUTE IMMEDIATE doesnt seem to fit for what I am trying to do.
Does anybody have any suggestions or re-design options I could use to achieve this generic procedure that will select from a certain synonym based on the DB info input parameters? Thanks.

Hi
rules engine style with table that holds the logic or code SQL directly in the procedure and IF THEN ELSE with db_id. Latter is better because SQL is native and objects are checked every time procedure is compiled.
James showed the simplest way but this rather complex way gives you more flexibility between instances if ever needed.

How to insert into a table with a nested table which refer to another table

Hello everybody,
As the title of this thread might not be very understandable, I'm going to explain it :
In a context of a library, I have an object table about Book, and an object table about Subscriber.
In the table Subscriber, I have a nested table modeling the Loan made by the subscriber.
And finally, this nested table refers to the Book table.
Here the code concerning the creation of theses tables :
Book :
create or replace type TBook as object
number int,
title varchar2(50)
Loan :
create or replace type TLoan as object
book ref TBook,
loaning_date date
create or replace type NTLoan as table of TLoan;
Subscriber :
create or replace type TSubscriber as object
sub_id int,
name varchar2(25)
loans NTLoan
Now, my problem is how to insert into a table of TSubscriber... I tried this query, without any success...
insert into OSubscriber values
*(1, 'LEVEQUE', NTLoan(*
select TLoan(ref(b), '10/03/85') from OBook b where b.number = 1)
Of course, there is an occurrence of book in the table OBook with the number attribute 1.
Oracle returned me this error :

Chadru, another option is for you to bind the table UI field to an internal table and to populate the internal table. Then, automatically, your Table UI field will be populated with the data from the internal table. Here is the code that does that and works for me. Good luck!
method FILL_DATA .
DATA: node_level1 type ref to if_wd_context_node,
      node_level2 type ref to if_wd_context_node,
      node_items type ref to if_wd_context_node,
      stru_ResItems type BAPI2093_RES_ITEM,
      tab_ResItems TYPE TABLE OF BAPI2093_RES_ITEM,
      n type i.
node_level1 = wd_context->get_child_node( name = 'BAPI_RESERVATION_CRE' ).
node_level2 = node_level1->get_child_node( name = 'CHANGING' ).
node_items = node_level2->get_child_node( name = 'RESERVATIONITEMS' ).
n = 2.
do n times.
    insert stru_ResItems into table tab_ResItems.
enddo.
node_items->bind_table( tab_ResItems ).
endmethod.

Can substitution strings be used for table name references?

Hi,
I was wondering if it's possible to use substituion strings for table names in SQL queries. This would allow for me to edit all references to a table at one location. For instance, if a table name or dblink changed, I could edit the substitution string or application item to ensure all the queries reference the new table.
For example:
select * from &table1.
table1 would be the substitution string for the actual table name
I know this is possible if I used a pl/sql function returning a query, but I would much rather use a substition string in a SQL query.
Thanks in advance.
Brian

i think not
because how create the fields of * in this case
in the other because all is dynamic, i think that you obtain only an error

How to create variant for table/view ?

Hi,
When I go through SM30, I find a radio button called variant. I don't know the effect.
Can anyone tell me how to create variant for table / view ?
I want to know when we need to create variant for table/view.
Best regards,
Chris Gu

hi ,
Whenever you start a program in which selection screens are defined, the system displays a set of input fields for database-specific and program-specific selections. To select a certain set of data, you enter an appropriate range of values.
For further information about selection screens, refer to Selection Screens in the ABAP User's Guide.
If you often run the same program with the same set of selections (for example, to create a monthly statistical report), you can save the values in a selection set called a variant
Procedure
To create a new variant:
       1.      On the ABAP Editor initial screen, enter the name of the program for which you want to create a variant, select Variants, and choose Change.
       2.      On the variant maintenance initial screen, enter the name of the variant to be created.
Note the naming convention for variants (see below).
       3.      Choose Create.
If the program has more than one selection screen, a dialog box for screen assignment appears. The dialog box does not appear if the program only has one selection screen. The selection screen appears in this case.
       4.      If there is more than one selection screen, select the screens for which you want to create the variant
5.      Choose Continue.
The (first) selection screen for the report appears.
If your program has more than one selection screen, use the scroll buttons in the left-hand corner of the application toolbar to navigate between them and to fill the fields with values. If you keep scrolling forwards, the Continue button appears on the last selection screen.
       6.      Enter the desired selection values, including multiple selection and dynamic selection.
       7.      Choose Continue.
