Msg 5105, Level 16, State 2, Line 1
A file activation error occurred. The physical file name ‘%.*ls’ may be incorrect. Diagnose and correct additional errors, and retry the operation.
This error message appears when a file activation error is encountered during a CREATE/ALTER DATABASE statement.
The T-SQL statement can be parsed, but causes the error at runtime.
Errors of the Severity Level 16 are generated by the user and can be fixed by the SQL Server user. The statement cannot be executed this way. This error can have multiple root causes, that you need to eliminate one by one.
All versions of SQL Server.
ALTER DATABASE MyExample
NAME = Test1dat2,
FILENAME = ‘abc.ndf’,
SIZE = 5MB,
MAXSIZE = 10MB,
FILEGROWTH = 50MB
In the above example we try to add a file named ‘abc.ndf’ to the MyExample database. Because the file extension .ndf is reserved for non-primary database files, the error is raised.
