Hi All, I tried to build a search feature using sql in zope, this is what I normal do in sql to do a range search : select * from table1 where table1_id = %field1_value% But when I try it with zope, it will become select * from table1 where table1_id = %'value'% Which return an error : [ODBC Microsoft Access 97 Driver] Syntax error in query expression 'table1_id alike %'field1_value'%'.") Any idea or work around ?? Please help Cheers Wai
