PDOStatement->nextRowset — Advances to the next rowset in a multi-rowset statement handle

Description

bool PDOStatement::nextRowset ( void )

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.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 Fetching multiple rowsets returned from a stored procedure

The following example shows how to call a stored procedure, MULTIPLE_ROWSETS, 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 = $stmt->fetch(PDO::FETCH_NUM);
    if ($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";
}
?>

The above example will output:

  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
