无法在 mySQL 中构建架构

Question

我有 mysql 架构

 CREATE TABLE foo(_id INTEGER PRIMARY KEY, name TEXT);

insert into foo (_id, name) values (1, "Foo A");
insert into foo (_id, name) values (2, "Foo B");

CREATE TABLE bar (_id INTEGER PRIMARY KEY, title TEXT);

insert into bar (_id, title) values (1, "Bar A");
insert into bar (_id, title) values (2, "Bar B");

CREATE TABLE bridge
(
    foo_id INT NOT NULL,  
    bar_id INT NOT NULL,  
    FOREIGN KEY (foo_id) REFERENCES foo(_id) ON UPDATE CASCADE,  
    FOREIGN KEY (bar_id) REFERENCES bar(_id) ON UPDATE CASCADE
)

在http://www.sqlfiddle.com/#!9/b0e77f，效果很好，但是当我尝试在桥中插入数据时

INSERT INTO bridge (foo_id, bar_id) values (1, 1);
INSERT INTO bridge (foo_id, bar_id) values (2, 1);

它说

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 'INSERT INTO bridge (job_id, cate_id) values (1, 1)' at line 9

Answer 1

CREATE TABLE bridge(...) ;:

后需要加分号

CREATE TABLE foo(_id INTEGER PRIMARY KEY, name TEXT);

insert into foo (_id, name) values (1, "Foo A");
insert into foo (_id, name) values (2, "Foo B");

CREATE TABLE bar (_id INTEGER PRIMARY KEY, title TEXT);

insert into bar (_id, title) values (1, "Bar A");
insert into bar (_id, title) values (2, "Bar B");

CREATE TABLE bridge
(
    foo_id INT NOT NULL,  
    bar_id INT NOT NULL,  
    FOREIGN KEY (foo_id) REFERENCES foo(_id) ON UPDATE CASCADE,  
    FOREIGN KEY (bar_id) REFERENCES bar(_id) ON UPDATE CASCADE
) ;  -- HERE

INSERT INTO bridge (foo_id, bar_id) values (1, 1);
INSERT INTO bridge (foo_id, bar_id) values (2, 1);

在 SQLFiddle 中，每个语句都应以终止符 (;) 结尾。更多信息在我的
