Sorry - switched address to the wrong list :(
*I* hate reply not going to the right place - but one of these days I switch to something that just ignores the on board miss direction ;)

I'm building a multi-database system, although my main targets are MySQL, Postgres, and SQLite. How would those handle something like "a string that ends in 100%"?Personally this is one of the reasons that PDO has never attracted me. Providing the tools to flatten some of the differences between *SQL* variations is just as important as flattening the name differences in functions. My own use of LIKE tends to process the string and then add the wrapping %% when passing it to the param array, but do all databases HANDLE 'escaped %' in the LIKE data? Firebird allows a escape character but you need to include it in the SQL LIKE '%100#%%' ESCAPE '#' But I think MySQL actually uses \% to achieve the same thing - and the ESCAPE '\' is then optional? -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/lsces/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
