MySQL-在表1中创建表2中创建记录

Question

Say I have 2 tables, ballplayers and stats in my Database.

when I add a ballplayers record (add someone new to the team) is there a way to create a new entry for that player in the stats table as well?

    ballplayers                           stats
 id, playername, number          id, totalpts, totalrebounds

(they are referenced using the id column in each table.)

So like this... Say I add to ballplayers

    ballplayers
 id, playername, number
  1    Nick        22

How can MySQL create a new entry in stats which is triggered on that entry creation in ballplayers with the given id and having defaults of totalpts and totalrebounds set to 0?

    stats
 id, totalpts, totalrebounds
  1     0           0

Is this bad DB design? Is it possible without having to write two queries? ( INSERT INTO ballplayers; & INSERT INTO stats; )Any help would be appreciated.

Answer 1

If you chose to go the route of a trigger, which would automatically add a row to the second table, you could do so using the following code:

create trigger trig_ballplayers_after_insert after insert on ballplayers
for each row insert ignore into stats values(new.id, 0, 0);
