PDOStatement::nextRowset
(PHP 5 >= 5.1.0, PHP 7, PECL pdo >= 0.2.0)
PDOStatement::nextRowset — Advances to the next rowset in a multi-rowset statement handle
Description
public PDOStatement::nextRowset ( ) : 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.
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 = $stmt->fetchAll(PDO::FETCH_NUM); if ($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:
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
