Google being useless tonight - now that's new :-) What I'm trying to do is the following and I'm certain there is a simple solution which eludes me: I have a query like this: SELECT a,b,c, (select problem from other_table where id=a) as problem FROM mytable WHERE a=1 So far so good. Actually "problem" always resolves to one record, so it's not the "multiple records returned" problem. What I try to do is this: SELECT a,b,c, (select problem from other_table where id=a) as problem FROM mytable WHERE a=1 and problem = 3 see the "problem=3" part in the where clause? The error I get is SQLError: (ProgrammingError) column "problem" does not exist Do I miss something? Shouldn't the "as" assignment make this virtual column available to the where clause? I think this should work and I know it works if I'd make a view out of the query. However, the query is built dynamically, so turning it into a view isn't really an option. Any pointer will be greatly appreciated.
