PDO::lastInsertId

Returns the ID of the last inserted row or sequence value

Description

public stringfalse PDO::lastInsertId(stringnull $name = null)

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 allows the name of any sequence object to be specified for the name parameter.

Note:
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.

Parameters

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

Return Values

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.

Errors/Exceptions

Emits an error with level E_WARNING if the attribute PDO::ATTR_ERRMODE is set to PDO::ERRMODE_WARNING.

Throws a PDOException if the attribute PDO::ATTR_ERRMODE is set to PDO::ERRMODE_EXCEPTION.
