Cause: When I restore the database, other users are using the database, so the above prompt will appear.

There are three solutions:

First, use the cursor to loop through all processes that are using the database and kill the process.

Declare @ dbname varchar (50)
Set @ dbname = 'database name'
Declare @ SQL varchar (50)
Declare cs_result cursor local for select 'Kill '+ cast (spid as varchar (50) from sys. sysprocesses where db_name (dbid) = @ dbname
Open cs_result
Fetch next from cs_result into @ SQL
While @ fetch_status = 0
Begin
Execute (@ SQL)
Fetch next from cs_result into @ SQL
End
Close cs_result
Deallocate cs_result
