I am trying to build a function which check for the schema and table in database if present then select the table values else create that schema and table and passing schema and table name as parameters of a function.
when calling this funtion it is throwing error
select * from master.chkbypram('xyz','04','9,8','4,5,9');
CREATEOR REPLACE FUNCTION master.chkbypram(schemaname text,state text,wallmaterial text,roofmaterial text)
