1 Problem description
First, in the work table, foreign keys are established for the two fields, employee and department, and then I want to look at the database relationship diagram, and an error is reported: the index exceeds the limit of the array. After testing other databases, the database relationship diagram can be created normally.
2 problem solved
Many solutions on the Internet say that the version is not OK. In view of the fact that other databases are OK, I think this method should not be OK, so I deleted the foreign key relationship, but it was still not OK, and then restarted SSMS, it was OK ! The database relationship diagram can be created normally!
