PL/SQL query IN comma deliminated string

Question

I am developing an application in Oracle APEX. I have a string with user id\'s that is comma deliminated which looks like this,

45,4932,20,19

Answer 1

I have faced this situation several times and here is what i've used:

SELECT * 
  FROM users u 
 WHERE ','||to_char(:P5_USER_ID_LIST)||',' like '%,'||to_char(u.user_id)||',%'

ive used the like operator but you must be a little carefull of one aspect here: your item P5_USER_ID_LIST must be ",45,4932,20,19," so that like will compare with an exact number "',45,'".

When using it like this, the select will not mistake lets say : 5 with 15, 155, 55.

Try it out and let me know how it goes;)
