Replacing MDF & LDF files from a tape backup

We have a database named 'lime' which became corrupt after a data import on Monday.

Path to the files is
E:\MSSQL Server\Data\MSSQL\Data\lime_Data.MDF
and
E:\MSSQL Server\Data\MSSQL\Data\lime_Data.LDF

I moved the lime_Data.MDF & lime_Data.LDF files to another location before restoring previous copy of the files from the image backup tape made on Friday into E:\MSSQL Server\Data\MSSQL\Data\

Now when use the SQL manager it shows lime(suspect). I tried putting back Modays files but still get the same 'suspect' mark on the database

Obviously moving the files and replacing them with previous ones has caused a problem. How can I get SQL to accept the files from Friday. (or any of the files!!)

Drop the database, create a new one with the same name and same files, stop sql server, overlay your database and log files, start sql server.

Hi hassalla,

I would be more tempted to use sp_attach_db to see if this works first, the example below creates a new copy of the pubs db from file copies of the mdf & ldf while SQL server is stopped:

sp_attach_db 'pubs3', 'C:\Program Files\Microsoft SQL Server\MSSQL\Data\pubs3.mdf', 'C:\Program Files\Microsoft SQL Server\MSSQL\Data\pubs3_log.ldf'

Essentially you can do exactly the same, but just try a different db name than your current db first like lime2.

FYI you can also use sp_detach_db to drop the current suspect databases without deleting the underlying mdf and ldf files

I would guess either works.  BOL says:

sp_attach_db should only be executed on databases that were previously detached

which is the case here.

Hi hassalla,

BOL is books on line, MSSQLs online help, drop in the sense that mastoo has used it means 'delete', and 'damage' in the way non_zero has used it. Overlay as mastoo has used implies file copying the files over the top of the existing files.

THANKS TO EVERYONE WHO CONTRIBUTED
all is well now.
I used the
sp_attach_db 'dbname'
method to clear things up.

no doubt I will be back with more questions about SQL as it took me a while to figure out stored procedures and hot ot run them. RTFM might have helped me.
