hi all,

SQL-specific (and probably different according to SQL version), so one
would need a mechanism to generalise this to other types of storage
(e.g. bdb).

>What are you trying to do with the like operator ?
 
 Thank Stephen for a lot!    I use 'like' for imprecise substring searching from database; such as string 'eagle' !='eag'  but 'eagle' like '%eag%'.
   As you say,I'd like to send my proplem mail to jabberd mail list!
best regards
