However,, I'd like to still insert the record and I'd like to do something like:
INSERT INTO test VALUES( 0, 'abc', 12345, IF( (SELECT foo FROM bar) ==
NULL, "postgres", <select_result>), /*more data follow*/);
What would be the best way to achieve this?
The “coalesce” function.
This is the query I use for my ODBC calls:
qry2 = L"INSERT INTO \"test\" VALUES( ?, ?, (SELECT c.oid
FROM pg_class c, pg_namespace nc WHERE nc.oid = c.relnamespace AND
c.relname = ? AND nc.nspname = ?), COALESCE((SELECT tableowner FROM
pg_tables WHERE tablename = ? AND schemaname = ?), \"postgres\"), ...)
ON CONFLICT DO NOTHING;";
Calling SQLExecute after parameter binding results in
"L"ERROR: column \"postgres\" does not exist;\nError while preparing
parameters"std::basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t>
