Обсуждение: pg_result

    I have looked all over the site and I can not find good description for
'pg_result'  I am having this problem.  My database and everthing is
working fine but when I try to run a query from an html webpage it is not
working and I believe it is my 'pg_result' command.  I have a table with
5-6 columns of information and I want total records to be selected.  I then
reference the call to a variable and call it further in my HTML, but
nothing prints up.  I have tried naming all the fields where 'row1' is
below but it also doesn't work.  I am not getting any errors and html
prints back except for any values for '$rows', not even the row1 values
will come back. My query command works fine in psql.
    Does anyone see my problem?

$result = pg_Exec($conn, "$query");
if (!$result);
        echo "An error occured inserting information into our database.\n";
        exit;
else;
        pg_close ($conn);
endif;
$rows = pg_result($result,0,"row1");

    Thanks in advance,
    Dave

(Assuming you're using php3)

I think something like this is what you're looking for:

   $conn = pg_Connect("localhost", "5432", "", "", "efakt");
   if (!$conn) {
      echo "Cannot connect to PostgreSQL database.\n";
      exit;
   }

   $result = pg_Exec($conn, "set datestyle='ISO';
             select * from invoices
              where seqid = $invid");
   if (!$result) {
      echo "Faktuur niet gevonden! ($resinv $invid)\n";
      exit;
   }


   $num = pg_NumRows($result);
   $i = 0;

   while ($i < $num) {
      echo pg_Result($result, $i, "invoiceno");
      $i++;
   }

   pg_FreeResult($result);
   pg_Close($conn);
