这是我正在创建的两个表的sql:
CREATE TABLE IF NOT EXISTS tbl_a(
id INT(6) UNSIGNED NOT NULL,
PRIMARY KEY(id)
)ENGINE = INNODB;
CREATE TABLE IF NOT EXISTS tbl_b(
id INT(6) UNSIGNED NOT NULL,
PRIMARY KEY(id),
FOREIGN KEY id REFERENCES tbl_a(id) ON DELETE CASCADE ON UPDATE CASCADE
)ENGINE = INNODB;
这是我得到的错误:
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 'REFERENCES a(id) ON DELETE CASCADE ON UPDATE CASCADE )ENGINE = INNODB' at line 4
有人可以建议我一个解决方案吗?

CREATE TABLE IF NOT EXISTS tbl_b(
id INT(6) UNSIGNED NOT NULL,
PRIMARY KEY(id),
FOREIGN KEY (id) REFERENCES tbl_a(id) ON DELETE CASCADE ON UPDATE CASCADE
