[Zope-DB] How to send comparison operations (such as > = ) to Z SQL?

[Qingliang Li]

Thanks for your relply. Maybe I can't state my question clearly.
I mean it raise error when i try the following example:

    select * from BAMD
       <dtml-sqlgroup where>
            .....
       <dtml-sqltest ID op=<dtml-var myOperation> type=nb optional>
            .....

where the myOperation is a variable (it could be "eq", "gt", etc.).
Is there a method that can handle such a problem?

Thanks.
