Question

Here\'s the query that fails:

CREATE TABLE `data` (
`id` int(10) unsigned NOT NUL         


        

Answer 1

After cruising through the answers above, and experimenting a bit, this is an effective way to solve Foreign Key errors in MySQL (1005 - error 150).

For the foreign key to be properly created, all MySQL asks for is:

• All referenced keys MUST have either PRIMARY or UNIQUE index.
• Referencing Column again MUST have identical data type to the Referenced column.

Satisfy these requirements and all will be well.
