Pregunta
I am trying to create foreign key for my database. My database is for a gym system.
I have the table called user. Within that table I have user_id which is my primary key. I have another table call member within this table I also have user_id which I want to make a foreign key so it relates to my user_id within the user table.
But i keep getting the following error..
#1452 - Cannot add or update a child row: a foreign key constraint fails (
Gym_System
.#sql-247a_3c1
, CONSTRAINT#sql-247a_3c1_ibfk_1
FOREIGN KEY (user_id
) REFERENCESmembers
(user_id
))
Can anyone help?
