Parse Comma(,) String in MySql stored procedure - mysql

Question

Stored procedure:
CREATE PROCEDURE lead_to_loan(xReffID_list text)
I want to use this xReffID_list variable in a select statement as
SELECT * FROM XXXX where xreffID IN (xReffID_list);
but the xreffID is a int Variable
How Can I use xReffID_list text which is a string of comma separated numbers in the INcondition for int variables ?
Stored procedure:

Answer 1

You can use find_in_set to do this:
SELECT * FROM XXXX WHERE find_in_set(xreffID, xreffID_list) > 0

Answer 2

Hey you can use cast() function available with Mysql
