AW: [Zope] multiple optional args to zsql method?

[Ulrich Wisser]

Hi,

I usually use a dml-if construct to do this

>>      <dtml-sqlgroup where>
>>        <dtml-sqltest name="id" op="eq" type="int" optional>
>>      <dtml-or>
<dtml-if zope_username>
>>        <dtml-sqltest name="zope_username" op="eq" type="string" optional>
</dtml-if>
>>      </dtml-sqlgroup>

only problem with this approach is, that you can not test
for a blank user name. In that case

<dtml-if "_.has_key('zpe_username')">

should help.

Ulli
