PDOStatement->nextRowset()

(PHP 5 >= 5.1.0, PECL pdo:0.2-1.0.3)

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

说明

PDOStatement

bool 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.

返回值

如果成功则返回 TRUE，失败则返回 FALSE。

范例

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";
}
?>

上例将输出：

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
