PDOStatement::nextRowset

Beschreibung

Some database servers support stored procedures that return more than one rowset (also known as a result set). PDOStatement::nextRowSet() enables you to access the second and subsequent rowsets associated with a PDOStatement object. Each rowset can have a different set of columns from the preceding rowset.

Rückgabewerte

Gibt bei Erfolg TRUE zurück, im Fehlerfall FALSE.

Beispiele

Beispiel 1. Fetching multiple rowsets returned from a stored procedure The following example shows how to call a stored procedure, MULTIPLE_RESULTS, that returns three rowsets. We use a do / while loop to loop over the PDOStatement::nextRowset() method, which returns false and terminates the loop when no more rowsets can be returned. <?php $sql = 'CALL multiple_rowsets()'; $stmt = $conn->query($sql); $i = 1; do {     $rowset = $stmt->fetchAll(PDO_FETCH_NUM);     if ($rowset) {         printResultSet($rowset, $i);     }     $i++; } while ($stmt->nextRowset()); function printResultSet(&$rowset, $i) {     print "Result set $i:\n";     foreach ($rowset as $row) {         foreach ($row as $col) {             print $col . "\t";         }         print "\n";     }     print "\n"; } ?> Das oben gezeigte Beispiel erzeugt folgende Ausgabe: Result set 1: apple red banana yellow Result set 2: orange orange 150 banana yellow 175 Result set 3: lime green apple red banana yellow
