You can't delete a branch that has any items or users (and possibly other data) associated with it. Edit or delete those first.

Hi, i want to delete some extra libraries from my koha system. Then, i could delete three from GUI; Koha-> Administration-> Libraries & Groups. But, there are more two including default "My library". Then i went to mysql an tried to delete those two library names, which are as sub-branch; but, i cannot delete those. Error shows:
mysql + #1451 - Cannot delete or update a parent row: a foreign key constraint fails
