Обсуждение: PHP3 and PostgreSQL

SORRY, WRONG SUBJECT IN PREVIOUS MESSAGE.

Hi all,

I'm trying to do the equivalent of the following command of
mysql (inside PHP3 code) in postgreSQL.

while (($row = mysql_fetch_object($result))) .....

I know there is the pg_fetch_object($result, ?) but I don't
know what to use for ?. I tried 0 and it does an exhaustive
search. I tried using something like $num

$num=0
while (($row = mysql_fetch_object($result,$num))) ...

$num++;

this is the error message I get :

Warning: Unable to jump to row 1 on PostgresSQL result index 2

Any ideas ?

thanks,
-Sheila

Try something like:
$NumRows = pg_NumRows($Result);
for ($CurRow =0; $CurRow < $NumRows;  $CurRow++) {
         $row = pg_Fetch_Object($Result, $CurRow);
         ....
}

I've never used Fetch_Object, but I know that this works with
Fetch_Array.  Also, if you consult the pg_Fetch_Object item in the quick
reference on http://www.php.net/ it will probably have a code example.

Oh I see there can help only Oliver Elphick or Paul DuBois.

The function prototype looks right now like:

/* {{{ proto object pg_fetch_object(int result, int row)
   Fetch a row as an object */

While the function prototype in MySQL looks:

/* {{{ proto object mysql_fetch_object(int result [, int result_typ])
   Fetch a result row as an object */

The optional result_typ is a constant and can be set to MYSQL_ASSOC,
MYSQL_NUM, or MYSQL_BOTH.

This means, you don't have a second row numbered 1 in result index 2.

PS: If this is misleading, I should read the PHP documentation myself a
couple of times.
