Przykłady

Przykład 1. Iterating through a forward-only cursor If you call db2_fetch_array() 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 ($row = db2_fetch_array($stmt)) {     printf ("%-5d %-16s %-32s %10s\n",         $row[0], $row[1], $row[2], $row[3]); } ?> Powyższy przykład wyświetli: 0 Pook cat 3.20 5 Rickety Ride goat 9.70 2 Smarty horse 350.00

Przykład 2. Retrieving specific rows with db2_fetch_array() from a scrollable cursor If your result set uses a scrollable cursor, you can call db2_fetch_array() 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_array($result, $i)) {     printf ("%-5d %-16s %-32s %10s\n",         $row[0], $row[1], $row[2], $row[3]);     $i = $i + 2; } ?> Powyższy przykład wyświetli: 0 Pook cat 3.20 5 Rickety Ride goat 9.70 2 Smarty horse 350.00
