Beispiele

Beispiel 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, $sql); while ($row = db2_fetch_assoc($result)) {     printf ("%-5d %-16s %-32s %10s\n",         $row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']); } ?> Das oben gezeigte Beispiel erzeugt folgende Ausgabe: 0 Pook cat 3.20 5 Rickety Ride goat 9.70 2 Smarty horse 350.00

Beispiel 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; } ?> Das oben gezeigte Beispiel erzeugt folgende Ausgabe: 0 Pook cat 3.20 5 Rickety Ride goat 9.70 2 Smarty horse 350.00
