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

[Qingliang Li]

Hi everyone,

I was confusing with such problem of Z SQL.
How can send comparison operations to  the  Z SQL?
I mean in the following example:
    select * from BAMD
       <dtml-sqlgroup where>
            .....
       <dtml-sqltest ID op=eq type=nb optional>
           .....
I want to send operations of "eq"/"gt"/"ne" ...(=, >, ....)  to  the 
"op"  according to user in the web interface.
Any help would be appreciated.
Thanks.
