If you want to filter your query by a variable column name, you can either use getattr() on a mapped class, or the ".c" dictionary on the underlying table. For example: # If Table is a mapped class colname = 'some_column' column = getattr(Table, colname) session.query(Table).filter(column == value) # If Table is an instance of sqlalchemy.Table colname = 'some_column' column = Table.c[colname] session.query(Table).filter(column == value) Hope that helps, Simon -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
