Questions tagged [mysql-error-1005]

If MySQL reports an error number 1005 from a CREATE TABLE statement, and the error message refers to error 150, table creation failed because a foreign key constraint was not correctly formed. Similarly, if an ALTER TABLE fails and it refers to error 150, that means a foreign key definition would be incorrectly formed for the altered table.

From the MySQL documentation:

  • If MySQL reports an error number 1005 from a CREATE TABLE statement, and the error message refers to error 150, table creation failed because a foreign key constraint was not correctly formed.
  • If an ALTER TABLE fails and it refers to error 150, that means a foreign key definition would be incorrectly formed for the altered table.
