I'm trying to get a list of fields returned by a dynamic SQL query. I've found a howto telling me to write something like : <dtml-in SQL.names> <dtml-var sequence-item> </dtml-in> But it doesn't work : I get the error "Attribute Error : names". I've tried with .items, .keys and .fields too. Well, since the SQL will return a list, firsly you would have to index it... also, .keys et al are Python stuff, so...(untested) <dtml-in "SQL[0].keys()"> might be more what you're looking for. Or... <dtml-in SQL> <dtml-in "keys()"> <dtml-var sequence-item> </dtml-in> </dtml-in> should iterate through the keys of each line of the returned table. It doesn't work too. I can't understand why. More general, I'd like to extract all the variables available in a namespace (and if I can do it, I'll can get the list of the fields).
