Can't create table (errno: 150)?

Question

i am using sequel pro on MACOSX and i've defined the table containing the foreign key and it still gives me this error 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

You need to specify which reference column is the target:

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)


)
