I posted a question earlier but that did not help me.

I need to insert data from joined files A - B into C

The tables are joined by the fields: SUN_DB & ACCOUNT_NR

BUT!!!!

The name of file B's is partial "variable" and comes out of file A
field: SUN_DB

Example:
Row of File A: field SUN_DB = "ZZZ" so File A has to be joined
with Table: "B_ZZZ" by the fields SUN_DB & ACCOUNT_NR

Row of File A: field SUN_DB= "YYY" so File A has to be joined
with Table: "B_YYY" by the fields SUN_DB & ACCOUNT_NR

There are +- 700 SUN_DB codes and so 700 TABLES TO JOIN WITH
IN SHORT I need to run +-700 joines between Table A and variable Table
Name B named: SALFLDG'||SUN_DB||'

Do I make myself clear?

I use the following script but some say it is far too complex for I
try to achieve. For me this script is working fine but it is ignoring
the following conditions "AND ACCNT_TYPE <> 'P' AND ANAL_A0 LIKE
'ABNA%'; "
Can anyone explain me why?

DECLARE retval INTEGER; CURSOR obj_cur IS

SELECT DISTINCT 'INSERT INTO C_SPIN (SUN_DB, ACCNT_CODE, TRANS_DATE,
AMOUNT, ANAL_A0, ANAL_T0)

SELECT SSRFACC.SUN_DB,SRFACC.ACCNT_CODE,TRANS_DATE,
AMOUNT,SSRFACC.ANAL_A0, ANAL_T0 FROM SSRFACC,SALFLDG'||SUN_DB||'

WHERE SSRFACC.ACCNT_CODE = SALFLDG'||SUN_DB||'.ACCNT_CODE AND
SSRFACC.SUN_DB ='''||SUN_DB||''' ' CMDSQL
FROM SSRFACC

WHERE SUN_DB LIKE 'B%' AND ACCNT_TYPE <> 'P' AND ANAL_A0 LIKE
'ABNA%';

drop_cursor INTEGER;
out_str VARCHAR2(1000);
BEGIN FOR obj_rec IN obj_cur LOOP drop_cursor :=
DBMS_SQL.OPEN_CURSOR;
out_str := obj_rec.cmdsql;
DBMS_SQL.PARSE (drop_cursor, out_str,
DBMS_SQL.NATIVE);
retval := dbms_sql.EXECUTE(drop_cursor);
DBMS_SQL.CLOSE_CURSOR (drop_cursor);
END LOOP;
END;

Hello ITAPORT06,
maybe it's worth to rethink your database design. What about putting all
700 tables into one adding a column sun_db so that you can join on this
column? This would eliminate the need for dynamic SQL altogether.

I don't see why the where condition is not executed but there is
something that you can improve:
I would put the dbms_sql.open_cursor and dbms_sql.close_cursor out of
the loop. A SQL cursor can be used for more than one SQL. You can reuse
it just by parsing a new SQL.
Maybe it would help to output the SQLs using dbms_output to see what's
wrong.
Eventually, you might have a look at the execute immediate feature of
Oracle 8i and up. This is a bit easier to handle and according to the
docs it is more performant.

Hope that helps,
Lothar

Lothar & Paul thank your for yor contribution but my prblem is still
not solved.

Paul: Yes the application I want to extract data from is Systems
Union Sun. So you are aware of the database structure. The dynamic sql
statement underneath works fine BUT I only have one problem is the
statement almost at the end of the script:

>WHERE SUN_DB LIKE 'B%' AND ACCNT_TYPE <> 'P' AND ANAL_A0 LIKE
>'ABNA%';

It does NOT ignore SUN_DB Like B% BUT is does ignore ACCNT_TYPE <>
'P' AND ANAL_A0 LIKE 'ABNA%'

It does not select records on the last 2 argument
Why is that and how can Isolve this?
Thanks

Sorry, I didn't really check the original SQL; I responded to the
'Redesign!' comment.
As to the original problem, is it an issue with nulls?
