Doing an insert into two related tables at once in MYSQL

I have two tables.   One is called dictionary, the other one is called tokendictionary.  
the identity column in the dictionary corresponds to a column in the tokendictionary called dindx.   Thus, when I make an entry in the dictionary, I need to make a corresponding entry in the tokendictionary such that the identity column in the dictionary equals the foreign key, dindx in the token dictionary.    I know how to do this using TSQL in a MS SQL database.

Here is an example of the script I use:
DECLARE id int;
BEGIN TRANSACTION;
INSERT INTO [dictionary] ([code], [acute], [gender], [codetype],  [codingsystem],[papplydate],[capplydate],[type]) VALUES
('0208T','a','n','p','9','9999-01-01','2014-01-01','0');
Select @id = SCOPE_IDENTITY();
INSERT INTO [tokendictionary] ([dindx], [token]) VALUES
( @id,'AUDIOMETRY AIR ONLY');
COMMIT TRANSACTION;

Open in new window


My question is, how do I do this in MYSQL?

LAST_INSERT_ID() is used in Mysql

Try to get identity like below
SELECT LAST_INSERT_ID() as fileId

INSERT INTO table1 (title,userid) VALUES ('test', 1);
SET @last_id_in_table1 = LAST_INSERT_ID();
INSERT INTO table2 (parentid,otherid,userid) VALUES (@last_id_in_table1, 4, 1);

You don't even have to use the variable in the middle. You can call the function directly in the second INSERT statement:

INSERT INTO table2 (parentid, otherid, userid) VALUES (LAST_INSERT_ID(), 4, 1);

The function works only with AUTO_INCREMENT fields.

This is a very nice solution to my problem.   It's so much easier than MS SQL.
