VPD Policy Tester
My VPD policies were causing troubles when I was running the Forms: ORA-28113 Policy Predicate Has Error . I could not easily figure out which Policy it was, as my data manipulation caused several triggers to fire that in turn performed queries and DML. So I wrote a simple procedure that can help me test all policies and find which ones are invalid.
It’s simple and really useful. Ideally it would disable all policies except the one being tested to be sure that any error is caused by that one. Feel free to add that functionality, I am under some time pressure right now.
create or replace procedure policy_tester is l_count number; procedure pl(p_text in varchar2) is begin dbms_output.put_line(p_text); end pl; begin for ply in ( select object_name, object_owner , policy_name , package from all_policies ) loop begin execute immediate 'select count(*) from '||ply.object_owner||'.'||ply.object_name into l_count; pl('Policy '||ply.policy_name||' on '||ply.object_owner||'.'||ply.object_name||' seems ok. ('||l_count||' records found)'); exception when others then pl('Error ('||sqlerrm||') in policy '||ply.policy_name||' on '||ply.object_owner||'.'||ply.object_name); end; end loop; end policy_tester; /
