Hello I have the following struture in my folders: sql - oracle - postgresql - odbc I've the idea to share most of the SQL-Methods via aqusition (they are in sql), but have the specific ones (not ANSI SQL) in the db folder (e.g Oracle with it's to_date function. I've tried this statement for an <dtml-in>: <dtml-set query="sql.oracle.browse()"> #1 See bottom <dtml-in "query" size=12 start=query_start> which works fine. I'd like to have it more dynamicly, so I tried: <dtml-set query_string="'sql.'+getDatabase()+'.browse()'"> #1 See bottom <dtml-set query="_.getitem(query_string)"> #1 See bottom <dtml-in "query" size=12 start=query_start sort="code,bez"> getDatabase is a Python-Script which get's the db for the folder (oracle,postgresql,odbc). But it doesn't find the object: Error Type: KeyError Error Value: sql.oracle.browse() This resource may be trying to reference a nonexistent object or variable sql.oracle.browse Anybody can give me an advice for the correct syntax? Thanks Dieter #1 I'm using the dtml-set tag, so <dtml-call "REQUEST.set(foo, 10)"> is: <dtml-set foo='10'>
