Get the Unique ID for the Last Inserted Row

Question

I want to get the Unique ID for the Last Inserted Row inside stored procedure, I make like this

DELIMITER //
 CREATE PROCEDURE addNewUsers(IN userName varchar(128),IN password varchar(128), IN addedBy INT)

BEGIN

 DECLARE id int default 0;

  id = mysqli_insert_id (insert into  `system_users`( `username`,`password`) values (userName ,md5(password)) );
  IF id <> 0 THEN     
        insert into  `user_profile`( `full_name`,`Date_time_ added`,`added_by`) values (userName ,CURRENT_TIMESTAMP(),addedBy ) where `user_id`=id ;
  END IF


END //

DELIMITER ;

This error occur

  #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '= mysqli_insert_id (insert into `system_users`( `username`,`password`) values (' at line 7

I doubt it's from mysqli_insert_id , what should I do ?

Answer 1

Your mysqli_insert_id is the problem, you're writing a MySQL stored procedure, not PHP. You want to use the last_insert_id() function:

LAST_INSERT_ID() (with no argument) returns a BIGINT (64-bit) value representing the first automatically generated value successfully inserted for an AUTO_INCREMENT column as a result of the most recently executed INSERT statement.

You also need to fix your assignment syntax. Something more like this:

DELIMITER //
CREATE PROCEDURE addNewUsers(IN userName varchar(128),IN password varchar(128), IN addedBy INT)
BEGIN
  DECLARE id int default 0;

  insert into  `system_users`( `username`,`password`) values (userName ,md5(password));
  set id = last_insert_id();
  if id <> 0 then
    -- ...
