SQL Server 2008 - Attach mdf without log - Operating system error 5: 5(Access is denied.)

问题

I am trying to attach database without log file.

Attach a SQL Server database with a missing transaction log file

Error on SSMS

Error on TSL

Msg 5120, Level 16, State 101, Line 1 Unable to open the physical file "....mdf". Operating system error 5: "5(Access is denied.)".

I'm not sa, but I'm in sysadmin role. I'm not really sure what access permission I need. Or is it because the .mdf is corrupted?

Thank in advance!

That's a bug in the SSMS interface. It can be done using T-SQL. Just don't include the log file in the list of files.

exec sp_attach_db 'dbname', 'filename'

sp_attach_db (Transact-SQL)

Start SQL Server manager as Administrator (right-click on the program, choose "Start as administrator"): problem solved!
