Question

I trying to use list of numbers like this.

SELECT *
FROM users
WHERE id in (list_of_ids)

this is part of sql procedure and the variable ‘list_of_ids’ is varchar and it contains id’s like this: 1,2,3,4,5……..
How can i use this list and this query

Answer 1

Try this as well. This could be the better solution as it wont require any additional function to create.
oracle regexp_substr will split comma seperated values into different rows and passes to query.

SELECT *
FROM users
WHERE id in 
(SELECT regexp_substr(list_of_ids,'[^,]+', 1, level) FROM dual
connect by regexp_substr(list_of_ids, '[^,]+', 1, level) is not NULL)
