int
mysql_insert_id ( [resource spojeni])
mysql_insert_id() returns the ID generated for
an AUTO_INCREMENT column by the previous INSERT query using the
given spojeni. If
spojeni isn't specified, the last
opened link is assumed.
mysql_insert_id() returns 0 if the previous
query does not generate an AUTO_INCREMENT value. If you need to
save the value for later, be sure to call
mysql_insert_id() immediately after the
query that generates the value.
Poznßmka:
The value of the MySQL SQL function
LAST_INSERT_ID() always contains the most
recently generated AUTO_INCREMENT value, and is not reset
between queries.
| Varovßnφ |
mysql_insert_id() converts the return type of
the native MySQL C API function
mysql_insert_id() to a type of
long (named int in PHP).
If your AUTO_INCREMENT column has a column type of BIGINT,
the value returned by mysql_insert_id()
will be incorrect. Instead, use the internal MySQL SQL function
LAST_INSERT_ID() in an SQL query.
