[MYSQL BUGS] UPDATE with double-nested queries and no default database

[11 Sep 2007 21:25] Keith Mendoza
This issue might be more an issue with the UPDATE statement, than the stored procedure. 
I attempted to execute an UPDATE statement involving 3 tables without first executing a USE database, 
and I got the same error warning. 
However, after I executed "use mysql" then reran the statement it worked.
