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

Описание

bool PDOStatement::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.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Примеры

Пример 1. Fetching multiple rowsets returned from a stored procedure

The following example shows how to call a stored procedure, MULTIPLE_RESULTS, 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";
}
?>

Результат выполнения данного примера:

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
