I need to write a Postgres function which executes a cursor. Query of this cursor however is created on the basis of parameters passed by user.
if(user_Input = 'a') l_query := l_query||a_from_clause ||'where ename in '||user_Input else if(user_Input = 'b') l_query := l_query||b_from_clause||'where ename in '||user_Input
OPEN csr FOR l_query;
How do we do it is postgres. My problem I know how to pass parameters like "ename=parameter", but If the SQL sentence is ename in (parameters). It does not work.
