I'm using the Pg package that came with 6.3, and I'm having problems using the
error codes generated by $result->resultStatus. Basically I just want to know
if a query came back null before I try to use it. Here's the code
$result = $conn2->exec("select totalusage from usage where name =
\'$username\'\;");
if ($result->resultStatus == PGRES_EMPTY_QUERY)
{
print "BAD VOODOO!\n";
}
The error message I continue to receive on empty queries is
PQgetvalue: There is no row 0 in the query results. The highest numbered row
is -1.
Can anyone tell me what I'm doing wrong here, and point me in the right
direction to using the error codes correctly?
thanks a ton!
