I'm trying to perform the following: SELECT * FROM table <dtml-sqlgroup where> <dtml-sqltest terminal op=like type=string optional> <dtml-and> <dtml-sqltest principal op=like type=string optional> <dtml-and> <dtml-sqltest product op=like type=string optional> </dtml-sqlgroup> if I pass only terminal and product I get the following: SELECT * FROM table WHERE terminal like 'foo' AND product like 'bar' but I need it to render like this: SELECT * FROM table WHERE terminal like '%foo%' AND product like '%bar%' so I read the mailing list archives and found out many people is doing a <dmtl-let fieldName="'%' + fieldNamel + '%'"> but this would break my optional attribute.. here's an example result using let on each field and passing only terminal and product as parameters: SELECT * FROM table WHERE terminal like '%foo%' AND principal like '%%' AND product like '%bar%' this is not tolerated since the principal field might be null, and doing a like '%%' would discard those entries. so, shouldn't dtml-test get patched to support at least the following op attributes: op=like_begin ( like '%foo' ) op=like_end ( like 'foo%' ) op=like_any ( like '%foo%' ) or is there any solution for this already? thanks Alex
