SQL & PL/SQL

Hi Friends,

I'm new to oracle. I have a IF condition that checks if the variable is not equal to empty. But the condition fails even if the variable has its value. I have added the part of the code below.

 v_MyTestVar := 'Success!' ;

 IF v_MyTestVar <> '' THEN
   DBMS_OUTPUT.PUT_LINE('v_MyTestVar IS NOT EQUAL TO NULL');
 END IF;

Please anyone help me with the solution for this problem.

Thanks,
Ram
