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:

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
