问题
I have a database created in SQL Server 2014 x64 express edition with SSMS 2014 and have some table in the database. I backup the database with this tsql
BACKUP DATABASE dbFile
TO DISK='D:\dbFile_170125.bak' WITH FORMAT;
In other computer, i have SQL Server 2016 x64 express edition with SSMS 2016. I create new database, then i restore database from file "dbFile_170125.bak" with replace option. The restore is success.
The problem is when i expand the Tables in Object Explorer in SSMS 2016, it show error :
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression. (Microsoft SQL Server, Error:512)
In SSMS 2014, there is no problem like that. Perhaps someone can help me. Thanks.

Multiple users have the problem, it seems, for now, the only solution is to roll back the update.
