PDOStatement->nextRowset()

Advances to the next rowset in a multi-rowset statement handle ()

PDOStatement {
  bool nextRowset();
}

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 1791. 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->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";

}
?>

The above example will output:
