        There is a standard, %, I don't know if its in writing but everything I've seen except Access uses it :) Access (and DAO) is used on windows only, so it made sense to use * as the 'match anything wildcard' which is what windows uses. James Sonork: Hasaki "I left there in the morning with their God tucked underneath my arm their half-assed smiles and the book of rules. So I asked this God a question and by way of firm reply, He said - I'm not the kind you have to wind up on Sundays." "Wind Up" from Aqualung, Jethro Tull 1971

          Well , I wrote a little app in VB that queries a table. I used DAO.I created a SQL generator that builds up a statement. But somehow only if I use * instead of % it works. For example , if i execute

          select * from Phonebook where Firstname like 'M*'

          I will get the appropriate records beginning with M. but if i write:

          select * from Phonebook where Firstname like 'M%'

          than all i get is an empty recordset! Why is that?! i remember that i used % before and it worked just fine. maybe someone knows what is the problem? thx!

          Because * replace the rest of characters and % replace only One Character.... For Example if you have a table with the following records Mother My Mine M* get all the records and M% only the Second Record... Best Regards Carlos Antollini. Sonork ID 100.10529 cantollini

                In T-SQL (SQL Server) the % character will do a wildcard beyond that point(all characters)

                'boo%' results in book, books, boobs....

                the _ character will act as a single wildcard

                'b_ok' will find anything for the second character(i.e. - book). Nick Parker

                      Dammit! I'm totaly confused now! Someone said that % is for one char and * for all. Someone else said % is standard and * for DAO/ADO. What happening!? :-) - Dan "Intel inside - Idiot outside"
