[ic] Nesting queries

[Peter Jakl <peter@jakl.net>]

Is it possible to nest [query] tags? I have one [query] that lists top level
categories and would like to list the selected subcategories with the main
category using another [query].

         [query list=1 st=db sql="select * from categories where
parent=null"]
         ... display main cat ...
         [if sql-code = [data session arg]]
         [then]
             [query list=1 st=db sql="select * from categories where
parent='[data session arg]'"]
             ... display sub-cat ...
             [/query]
         [/then]
         [/if]
         [/query]

Thanks,

Peter
