I tried to insert data using an zsql, insert fine How manage error with zsql.
Before
<dtml-try>
   <dtml-call insert_data>
   Data inserted!!!
<dtml-except>
   Error type:<dtml-var error_type>
   Error type:<dtml-var error_value>
</dtml-try>



Now (All files are ZPT)

[index_html]
...
<form action="proyecto_alta.html">
    <input type="text" name="field1" id="field1" />
    ...
    <input type="text" name="field2" id="field2" />
</form>


[proyecto_alta.html]
<div tal:on-error="structure here/error_insertar">
       tal:condition="context/insert_data.zsql"
       tal:content="string: Data inserted!!!">

</div>


[error_insertar]
error=_['error']
if error.type==ZeroDivisionError:
    return "<p>Can't divide by zero.</p>"
else:
    return """<p>An error ocurred.</p>
              <p>Error type: %s</p>
              <p>Error value: %s</p>""" % (error.type,
                                           error.value)


But say
