PDOStatement::nextRowset

(PHP 5 >= 5.1.0, PECL pdo >= 0.2.0)

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

Descrição

public 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.

Valor Retornado

Retorna TRUE em caso de sucesso ou FALSE em caso de falha.

Exemplos

Exemplo #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";
}
?>

O exemplo acima irá imprimir:

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.
