mysql - 无法创建表(errno : 150)?

Question

我在 MACOSX 上使用 sequel pro，我已经定义了包含外键的表，它仍然给我这个错误 Can't create table (errno: 150)

CREATE TABLE members (
mem_id INTEGER,
f_name VARCHAR(10),
l_name VARCHAR(10),
address VARCHAR(40),
name VARCHAR(20),
domain VARCHAR(15),
PRIMARY KEY(mem_id)
)

CREATE TABLE member_phone (
mem_id INTEGER,
phone_no INTEGER,
PRIMARY KEY (mem_id,phone_no),
FOREIGN KEY (mem_id) REFERENCES members
)

Answer 1

您需要指定目标引用列:

CREATE TABLE members (
mem_id INTEGER,
f_name VARCHAR(10),
l_name VARCHAR(10),
address VARCHAR(40),
name VARCHAR(20),
domain VARCHAR(15),
PRIMARY KEY(mem_id)
)

CREATE TABLE member_phone (
mem_id INTEGER,
phone_no INTEGER,
PRIMARY KEY (mem_id,phone_no),
FOREIGN KEY (mem_id) REFERENCES members (mem_id)


)
