Hi Jorge,
Here is an example from www.zopeonarope.com, notice that there is only
one sqlgroup with a 'where'. The other sqlgroup tags lie between
dtml-and tags producing "and" logic. The idea is that you can supply
various parameters, and depending which ones are not the empty string,
different renderings of the template will result with the correct logic.
01 selectSQL:
02
03 <params>personID="" passwd="" roles=""
domains=""</params>
04 select personID, passwd, roles, domains from
Passwords_Basic
05 <dtml-sqlgroup where>
06
07 <dtml-sqlgroup>
08 <dtml-if personID>
09 <dtml-sqltest personID type=string>
10 </dtml-if>
11 </dtml-sqlgroup>
12 <dtml-and>
13 <dtml-sqlgroup>
14 <dtml-if passwd >
15 <dtml-sqltest passwd type=string>
16 </dtml-if>
17 </dtml-sqlgroup>
18 <dtml-and>
19 <dtml-sqlgroup>
20 <dtml-if roles >
21 <dtml-sqltest roles type=string>
22 </dtml-if>
23 </dtml-sqlgroup>
24 <dtml-and>
25 <dtml-sqlgroup>
26 <dtml-if domains >
27 <dtml-sqltest domains type=string>
28 </dtml-if>
29 </dtml-sqlgroup>
30
31 </dtml-sqlgroup>
Maybe give that a try?
take care,
-steve
