SELECT * from table where fieldname LIKE '% $textinupt %' but it is giving case sensitive result bcos the field which im comparing with text input is blob. what should i do to avoid case sensitive result??? is it required to convert input text also in boob format?? then how to do that?? thnx and regds, smita. _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com
