如何获取主键字段的最后插入值？

I am using MySQL.I have to get the last inserted record's primary key value. How can i get this?

This will return the last inserted id.

SELECT LAST_INSERT_ID();

OR

if ((result = mysql_store_result(&mysql)) == 0 &&
    mysql_field_count(&mysql) == 0 &&
    mysql_insert_id(&mysql) != 0)
{
    used_id = mysql_insert_id(&mysql);
}

mysqli_insert_id()
PDO::lastInsertId()
mysql_insert_id()

It's well worth checking the documentation if you are likely to meet "race" conditions. http://uk3.php.net/manual/en/function.mysql-insert-id.php etc.

Use follwoing query:

  SELECT LAST_INSERT_ID();

There are two function that return this value:

mysql_insert_id()--> PHP function

LAST_INSERT_ID()--> MySQL function that can be used by PHP and other Languages or in MySQL command line interface or MySQL front-end
