i tried this but the call to PQresultErrorField(PGresult, PG_DIAG_SQLSTATE)
is returning NULL, this is what trigger the exception in the function code:
ereport(ERROR,(errcode(ERRCODE_SQL_ROUTINE_EXCEPTION),errmsg("Plan with id
%s does not allow balance with id %s",plan_id,in_balanceid)));
and this is the caller code:
if(PQresultStatus(pg_res) == PGRES_FATAL_ERROR)
{
char *t = PQresultErrorField(pg_res,PG_DIAG_SQLSTATE);
log_debug("[C%03dH%03d] PQres returned NULL:
%s",handler->my_connection->id,handler->id,t);
}
the above call log_debug show that t is NULL. am i doing something wrong ?
thanks!
