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

    Опис

    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.

    Приклади

    Приклад #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";
    }
    ?>

    Поданий вище приклад виведе:

    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);
    ?>
