One more thing. Right now, when I use AsValue of Select inside Insert:
sql & Insert(USERS)(USER_OID, Select(OID).From(PG_ROLES).Where(ROLNAME == User.GetData()).AsValue() )(USER_NAME, Name.GetData())(USER_SURNAME, Surname.GetData());
sql string looks like this:
insert into USERS(USER_OID, USER_NAME, USER_SURNAME) values (select oid from pg_roles where rolname = 'aaaaaaaa', 'aaaaa', 'aaaaaaa')
There should be another pair of parentheses around select, so AsValue should look like this:
SqlVal AsValue() const { return SqlVal(String("(") << text << ")", SqlVal::LOW); }
