Some database servers support stored procedures that return more than one
|
|
rowset (also known as a result set).
|
|
<function>PDOStatement::nextRowSet</function> 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.

<title>Fetching multiple rowsets returned from a stored procedure</title>
|
|
<para>
|
|
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 <function>PDOStatement::nextRowset</function> method, which
|
|
returns false and terminates the loop when no more rowsets can be returned.
