Returns the ID of the last inserted row, or the last value from a
|
|
sequence object, depending on the underlying driver. For example,
|
|
<function>PDO_PGSQL</function> requires you to specify the name of
|
|
a sequence object for the <parameter>name</parameter> parameter.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
This method may not return a meaningful or consistent result across
|
|
different PDO drivers, because the underlying database may not even
|
|
support the notion of auto-increment fields or sequences.
