PHP 8.4.2 Released!

PDOStatement::nextRowset

(PHP 5 >= 5.1.0, PHP 7, PHP 8, 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.

Parameters

This function has no parameters.

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, which returns three rowsets. We use a do-while loop to call the PDOStatement::nextRowset() method until it returns false and terminates the loop when no more rowsets are available.

<?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

PDO::nextRowset() does not appear to be currently supported by the Firebird PDO driver. Unfortunate.

on MSSQL and 'dsn' => 'dblib:...',:
If you know how many count rowset then don't use contruction of do..while.

<?php
do {
$pdoStatement->fetchAll(\PDO::FETCH_ASSOC);
} while (
$pdoStatement->nextRowset()
);
?>
When I get large fetchAll(over 30) for second nextRowset. I get error - Segmentation fault.

Uses step-by-step insted do..while is fix for this bug:
<?php
$pdoStatement
->fetchAll(\PDO::FETCH_ASSOC);
$pdoStatement->nextRowset();
$pdoStatement->fetchAll(\PDO::FETCH_ASSOC);
?>
