I'm trying to create a table in a MySQL database that has three foreign keys, but am getting an error. This error is not obvious to me, and can use a third party check.
CREATE TABLE `main_message`(
id INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
strat_key INT NULL,
task INT NULL,
user INT,
comment VARCHAR(255) NOT NULL,
datestamp DATETIME,
FOREIGN KEY strat_key REFERENCES prod_main_strategicdirection(id) ON UPDATE CASCADE ON DELETE CASCADE,
FOREIGN KEY task REFERENCES main_task(id) ON UPDATE CASCADE ON DELETE CASCADE,
FOREIGN KEY user REFERENCES prod_auth_user(id) ON UPDATE CASCADE ON DELETE CASCADE,
) ENGINE = INNODB;
According to the output, I'm getting the error message
You have an error in your SQL syntax; check the manual that corresponds to your
MariaDB server version for the right syntax to use near ' foreign key strat_key
references prod_main_strategicdirection(id) on update cas'
just after the first foreign key declaration
FOREIGN KEY strat_key REFERENCES prod_main_strategicdirection(id)
but I see nothing obvious to what would be causing the error.
CREATE TABLE `main_message`(
id INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
strat_key INT NULL,
task INT NULL,
user INT,
comment VARCHAR(255) NOT NULL,
datestamp DATETIME,
FOREIGN KEY(strat_key) REFERENCES prod_main_strategicdirection(id) ON UPDATE CASCADE ON DELETE CASCADE,
FOREIGN KEY(task) REFERENCES main_task(id) ON UPDATE CASCADE ON DELETE CASCADE,
FOREIGN KEY(user) REFERENCES prod_auth_user(id) ON UPDATE CASCADE ON DELETE CASCADE
) ENGINE = INNODB;
Using FOREIGN KEY Constraints:
[CONSTRAINT [symbol]] FOREIGN KEY
[index_name] (index_col_name, ...)
REFERENCES tbl_name (index_col_name,...)
[ON DELETE reference_option]
[ON UPDATE reference_option]
reference_option:
RESTRICT | CASCADE | SET NULL | NO ACTION
