如果从机器上删除了 .mdf 和 .ldf 文件，如何从 SQL Server 中删除数据库？

Question

I have restore database into SQL Server as WMDATA.

One day my friend using my machine and removed .mdf and .ldf file for WMDATA.

Now I want to remove WMDATA database from my SQL Server but it gives me error for .mdf and .ldf file.

Answer 1

DROP DATABASE WMDATA should work, because it will drop a database even if it is suspect .

If that doesn't help, you should add some more useful information: what version of MSSQL; how are you dropping the database; what is the error message etc. You might also get a better answer on the DBA or Server Fault sites.

Answer 2

I run into this issue as well, while trying to delete some localdb databases through SSMS and DROP DATABASE didn't work for me. However, I found that it is possible to "recreate" the database after an unsuccessful deletion. I did the following:

1. Delete the database, get error that .mdf files are missing.
2. Create new database with the same name.
3. Delete the database again, this time without errors.

PS: If you don't do step 1, you get an error in step 2 that a database with that name already exists.

Answer 3

Right click on the DB > Delete

Uncheck "Delete backup and restore history information for databases" Check "Close existing connections"

And hit OK.
