How to convert varchar2 to = , and operators

Question

I have a procedure like
create or replace procedure emp_fill(operator1 varchar2, operator2 varchar2, emp_salary number, emp_comm number)
is
begin
select * from employees where salary [>|=|<] emp_salary and commission_pct [>|=|<] emp_comm;
end;
Now the problem is I am sending operator parameter in this procedure either '>' or '=' or '<'
But I cannot write select * from employees where salary operator1 emp_salary and commission_pct operator2 emp_comm;
What I have to do to convert operator1 and operator2 which are varchar2 type, to change them as [>|=|<] operators and use them in the procedure.
pls help

Answer 1

First of all:
You are assuming PL/SQL has the same syntax as T-SQlL. As Microsoft doesn't understand a procedure can't return anything other than via an OUT parameter the procedure is wrong anyway.
For this time only (I hate people asking doc questions) I will correct your code.
create or replace procedure emp_fill(p_operator1 varchar2, p_operator2 varchar2, p_emp_salary number, p_emp_comm number, cv OUT sys_refcursor)
is
begin
open cv for
'select * from employees where salary '||p_operator1|| ' :p_emp_salary '
||' and commission_pct '||p_operator2||' :p_emp_comm' using p_emp_salary,p_emp_comm;
end;
