Re: insert ..... returning <column> problem

I was just trying to use it similar to oracle handling in "returning COLUMN into :VAR"
So in postgres I should not explicitly specify destination variable for 'returning'
value in query itself, but rather retrieve the result from PGresult returned by PQexec().
ok, thanks for clarification!
