This has been repeatedly dealt with here in the c.d.o. usenet groups over the last three or four months. Until 9i CASE was handled in the SQL engine and not in the PL/SQL engine. So in 8i it works in SQL*Plus and in native dynamic SQL. In 9i it works everywhere. So if you need it in a stored procedure just wrap it in NDS.
