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

### Descrierea

public PDOStatement::nextRowset ( void ) : bool

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.

### Exemple

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 = $stmt->fetchAll(PDO::FETCH_NUM);
if ($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";
}
?>`
