Comments for Dynamic IN-Lists
Nicole said...I used something like this and it worked fine for me:
CREATE OR REPLACE TYPE in_list_t AS TABLE OF VARCHAR2 (4000);
CREATE OR REPLACE TYPE in_list_v AS VARRAY(10) OF VARCHAR2 (4000);
WHERE job IN (SELECT pl.column_value FROM TABLE(CAST(in_list_v('SALESMAN, MANAGER') AS in_list_t)) pl)
ORDER BY ename;
DROP TYPE in_list_t;
DROP TYPE in_list_v;
Mark said...I think it might be worth mentioning that use of the "MEMBER OF" construct is not 100% equivalent to the "sub-SELECT from TABLE" construct in the sense that the former will cause the table function to be called for EACH row/value that is tested! (Tested on 10gR2 by including some dbms_output to the function to show each invocation.)

Durga said...Thank you for the solutions given here.
In the Temporary Table Sub-Select example, the data or the IN-list data has VARCHAR datatype.
It will help us if you demonstrate the same example when the IN-list has Numeric data.
Can you please post an example wherein the IN-list has numeric datatypes?
I had tried to write a code on similar lines but i got ORA-03001 ora-03001 unimplemented feature
As requested, each section has a number in-list example at the end. :)
Markus said...You can also use CONNECT BY with REGEX:
WHERE empno IN (SELECT REGEXP_SUBSTR('7782 7566 7369 7521', '\d+', 1, level) FROM DUAL
CONNECT BY REGEXP_SUBSTR('7782 7566 7369 7521', '\d+', 1, level) IS NOT NULL
ORDER BY ename
