Список параметров

A valid stmt resource containing a result set.

Примеры
Пример #1 Iterating through a forward-only cursor
If you call db2_fetch_assoc() without a specific row number, it automatically retrieves the next row in the result set.
<?php
$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$stmt = db2_prepare($conn, $sql);
$result = db2_execute($stmt);
while ($row = db2_fetch_assoc($stmt)) {
printf ("%-5d %-16s %-32s %10s\n",
$row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']);
}
?>
Результат выполнения данного примера:
0 Pook cat 3.20 5 Rickety Ride goat 9.70 2 Smarty horse 350.00
Пример #2 Retrieving specific rows with db2_fetch_assoc() from a scrollable cursor
If your result set uses a scrollable cursor, you can call db2_fetch_assoc() with a specific row number. The following example retrieves every other row in the result set, starting with the second row.
<?php
$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$result = db2_exec($stmt, $sql, array('cursor' => DB2_SCROLLABLE));
$i=2;
while ($row = db2_fetch_assoc($result, $i)) {
printf ("%-5d %-16s %-32s %10s\n",
$row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']);
$i = $i + 2;
}
?>
Результат выполнения данного примера:
0 Pook cat 3.20 5 Rickety Ride goat 9.70 2 Smarty horse 350.00
