Subject COMPUTED BY (SELECT SUM("Cost") FROM Costs WHERE Costs.ID = ID)
Author Raymond Kennington
The manual states that <expr> for a COMPUTED column can be any valid query that returns a single
result set.

The following gives an error like 'unknown token' for SELECT:

COMPUTED BY (SELECT SUM("Cost") FROM Costs WHERE Costs.ID = ID)

so is it possible?
