# PDO->lastInsertId()

(no version information, might be only in CVS)

PDO->lastInsertId() -- Returns the ID of the last inserted row or sequence value

## Descrição

class PDO {
string lastInsertId ( [string name] )
}

Returns the ID of the last inserted row, or the last value from a sequence object, depending on the underlying driver. For example, PDO_PGSQL() requires you to specify the name of a sequence object for the `name` parameter.

> Nota: 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.

## Parâmetros

`name`

  Name of the sequence object from which the ID should be returned.

## Valores de retornado

If a sequence name was not specified for the `name` parameter, PDO->lastInsertId() returns a string representing the row ID of the last row that was inserted into the database.

If a sequence name was specified for the `name` parameter, PDO->lastInsertId() returns a string representing the last value retrieved from the specified sequence object.

If the PDO driver does not support this capability, PDO->lastInsertId() triggers an `IM001` SQLSTATE.
