... 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

Do it in a "Script (Python)". It is much easier there.... Apart from that: "vypisSQL_LET[listing_number]" is the next hit (provided it exists). Thus, "vypisSQL_LET[listing_number].column" is the "column" field of the next hit. Be aware that you need to handle the boundary case (that you are already at the last hit). -- Dieter
