PDO::lastInsertId --
Returns the ID of the last inserted row or sequence value
Description
string
PDO::lastInsertId ( [string name] )
Returns the ID of the last inserted row, or the last value from a
sequence object, depending on the underlying driver.
注:
This method may not return a meaningful/consistent result across different PDO
drivers, because the underlying database may not even support the notion
of auto-increment fields or sequences.
返回值
If a sequence name was not specified for the name
parameter, PDOStatement::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, PDOStatement::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.
