PDO::nextRowset() does not appear to be currently supported by the Firebird PDO driver. Unfortunate.
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
Descrizione
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.
Elenco dei parametri
Questa funzione non contiene parametri.
Valori restituiti
Restituisce true in caso di successo, false in caso di fallimento.
Esempi
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";
}
?>Il precedente esempio visualizzerà:
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

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);
?>

If you use PDO::fetch instead of PDO::fetchAll and do not reach the end the result set, PDO::nextRowset() will fail with "SQLSTATE[HY000]: General error: PDO_DBLIB: dbresults() returned FAIL."
