Re: Another nut to crack with insertion into tables... *sigh* - Mailing list pgsql-sql

I dunno about arrays, but this one I think I can answer:

I believe sub-selects are currently only supported in WHERE clauses.
Supporting them elsewhere is on the TODO list for a future release
(no, 6.4 won't have it).  In the meantime you'll have to read back
the result of the sub-select and include it in the text of the INSERT.

(I'm not sure whether the SQL spec allows a select in an INSERT like this
anyway.  What happens if the sub-select returns no tuples, or more than
one tuple?)
