Depending on the way a database is configured, one may be using char fields which are 'blank packed' fixed length, or varchar which would normally only include white space when it is actually added. It's not uncommon though to cast numeric fields to 'char' to create fixed length records and I would not like to say how many legacy systems still use that approach for building tables of data? -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
