mysql - MySQL で last_insert_id() を使用するには?

Question

次のような私のSQL文：

INSERT INTO foo (val1) VALUES('v1');      -- ID in first table
foo_id = SELECT last_insert_id();

INSERT INTO bar (val2) VALUES ('v2');     -- ID in second table
bar_id = SELECT last_insert_id();

INSERT INTO foobar (foo_id, bar_id, val3)
VALUES (foo_id, bar_id, 'text');          -- third table

上記は機能していませんfoo_id = statement。

Answer 1

INSERT INTO foo (val1) VALUES ('v1');     -- ID in first table
SET @foo_id = last_insert_id();

INSERT INTO bar (val2) VALUES ('v2');     -- ID in second table
SET @bar_id = last_insert_id();

INSERT INTO foobar (foo_id, bar_id, val3)
VALUES (@foo_id, @bar_id, 'text');        -- third table
