Yesterday, one of my colleague asked that if he traced a wrap’ed PL/SQL procedure, would the SQL statements show up in the trace ? Very simple thing but at that moment i got, sort of into doubt. So i ran a simple test and yes they do show up 😉

CREATE OR REPLACE PROCEDURE wrap1
AS
v_today   DATE;
BEGIN
SELECT SYSDATE
INTO v_today
FROM DUAL;
END;
/

C:\>wrap iname=wrap1.sql

And here is the output from the trace file, showing the SQL statement:

BEGIN wrap1; END;
