Hi,
 
does somebody knows how to get next iterations of columns from SQL query? I think that is only due my unknowledge of right pythonic syntax.
 

<dtml-let vypisSQL_LET="vypisSQL()"> -- ZSQL method results catch
<dtml-in vypisSQL_LET prefix="listing">
 
current value: <dtml-var column>
next value: <dtml-var "vypisSQL_LET.column[listing_number]"> -- here is an error

</dtml-in>
</dtml-let>
 
Do you have some ideas how to get next value, please?
 
It is possible to do with fill ['','',''....] fields or with memorizing/display last values as a main result, but it is not what I want, it is quite large sequence and ### columns.
 
Many thanks, JL.
