Re: question about CONTAINS SQL
Hello Paul, If it like your mean,these parameters aren't beneficial to help user to ensure the correctness with their code. On the contrary,mysql depend on these parameters to ensure the integrality and security. If it like this,these parameters increase use difficulty about user. Should mysql to perfect these function? - Original Message - From: Paul DuBois [EMAIL PROTECTED] To: Rhino [EMAIL PROTECTED]; wangxu [EMAIL PROTECTED] Cc: mysql mysql@lists.mysql.com Sent: Friday, January 20, 2006 3:20 PM Subject:Re: question about CONTAINS SQL At 8:29 -0500 1/19/06, Rhino wrote: I am copying the rest of the list with this so that everyone may benefit from the discussion.

I use DB2 a lot more than I use MySQL - and I'm not currently using a version of MySQL that supports stored procedures and user-defined functions - so I assumed that the MODIFIES/READS/CONTAINS clauses actually _do_ something in MySQL. Since MySQL and DB2 both try to follow roughly the same SQL standards that seemed like a reasonable assumption. Obviously, I was wrong and bow to your superior knowledge of what MySQL actually does with these clauses. If the MODIFIES/READS/CONTAINS clauses are just checked for spelling and otherwise ignored, i.e. if they are not enforced, then why does Wangxu's procedure not work? Again, my version of MySQL doesn't support procedures so I can't try it for myself.
