MySQL get Primary Key after Insert Statment

问题

I need to use the following insert statement, and the primary key field is auto increment. I need to return the new primary key value after the insert. Preferably using one statement to do the insert and return primary key value.

$query = $database->connection->prepare("INSERT INTO accounts (created, priviledge, password, token, idle) VALUE ('$created', '1', :password, '$token_encrypt', '$idle')");    
$query->bindParam(":password", $password_hash);    
$query->execute();

回答1:

As soon as you're using PDO you need to use

$database->connection->lastInsertId()

And it guarantees you to return the value from the current session. So answering to your question from comments - there is no chance you get the wrong value from a concurrent session.

回答2:

assume your primary field name is id then try this code

SELECT max(id) FROM tableName

or try this

LAST_INSERT_ID();

回答3:

Use mysql_insert_id(); to get the ID generated in the last query.

It retrieves the ID generated for an AUTO_INCREMENT column by the previous query (usually INSERT).

回答4:

DELIMITER $$
DROP TRIGGER IF EXISTS `TR_AI_mytable`;
CREATE TRIGGER `TR_AI_mytable` AFTER INSERT 
    ON `mytable` FOR EACH ROW 
BEGIN
    SET @mylastPK = new.PKField;
END;
$$
