[Zope] ZSQL Method Question

Fri, 25 Feb 2000 09:36:59 -0600

Your question intrigued me so I played around a little.  

This works:

Number of rows in query = <dtml-var "_.len(t1)"><br>
<dtml-with "_.namespace(t1=Query.OrderItems())">
<dtml-var "t1[0].orderdetid" html_quote> <dtml-var "t1[0].engname" html_quote><br>
<dtml-var "t1[1].orderdetid" html_quote> <dtml-var "t1[1].engname" html_quote><br>
<dtml-var "t1[2].orderdetid" html_quote> <dtml-var "t1[2].engname" html_quote><br>
<dtml-var "t1[1].orderdetid" html_quote> <dtml-var "t1[1].engname" html_quote><br>
<dtml-var "t1[5].orderdetid" html_quote> <dtml-var "t1[5].engname" html_quote><br>
</dtml-with>

you will, of course need to substitute your own query and column names

This wasn't originally my line of questioning, but it inspired me...and I
subsequently became stuck.

I've done the following:
<dtml-call "REQUEST.set('rows',MaintNames())">
and successfully set 'rows' to the value returned by the SQL Method
MaintNames.  I can <dtml-in rows> through the list and do fun stuff.

After scouring the documentation, I still can't find how to select the
values from an arbitrary row, say row 3 without combining <dtml-in> and
<dtml-if> while using the sequence-item value.  Is there a more elegant way?

If your SQL Method is called sql_GetAll then you can do something like:

<!-- Get the rows -->
<dtml-call "REQUEST.set('rows',sql_GetAll())">

<!-- Display the total number of rows -->
<dtml-var "_.len(rows)">

<!-- Display the records -->
<dtml-in rows>
  <!-- whatever -->
</dtml-in>

That way you can unlink the code that writes the hidden form input field
from the dtml-in code.

HTH.
