Thank you for your response. Actually, I was trying to address the following query.
select LIEN_AC_NO from deposit_lien where deposit_no='0002114029832' and deposit_sub_no='1' and unlien_dt is null and unlien_remarks is null;
In the above query "deposit_sub_no" column is "numeric" type and passing '1' (as varchar). To address this I'd created the function and operator as I'd mentioned in the earlier mail. Even the following query throws error after creating the function and operator.
select * from deposit_lien where deposit_no='0002114029832';
ERROR: operator is only a shell: character varying = numeric LINE 1: select * from deposit_lien where deposit_no='0002114029832' ^ SQL state: 42883 Character: 44
In the above query "deposit_no" column is having "varchar" data type. But before creating the function and operator it was working fine. Tried dropping the same, even though the same error. How to proceed now?

Your operator has numeric on the left and varchar on the right. But your query is doing numeric on the RIGHT. Probably want to make a matching one to cover both cases.
