QUESTION
I inherited a database, there is no backup.
This database was created on SQL Server 2017 (v14) and the server is no longer available.
I have the .MDF
, .LDF
and the filestream.hdr
files.
Now I want to attach this database to SQL Server 2017.
As you guess it, the attached process fails.
If I try to attached from Management Studio, I get an error that the file stream folder cannot be located.
However, if I point to the folder in script, I get File Activation Error.
There are two folders in the MyDB_Filestream folder but both are empty.
$FSGC
and $FSLOG
What am I missing?
...ANSWER
Answered 2021-May-11 at 05:23Based on another post I did the following to resolved this issue:
Create a new database with the same name as the database I am attempting to attach. (The MDF and LDF names must match)
Take the database offline and terminate all connections.
Go to the folder where the new database is located and delete both the MDF and LDF files.
Copy the files of the database I am attempting to attach and put them into the exact folder where the new DB was located before they were deleted.
Make sure SQL Server has adequate access to the pasted DB file, MDF, LDF.
Now in SSMS bring the database back online.
I did the above and everything worked.
I immediately backed-up the databases.

Syncing a windows app with a linux website, I use a bash script which transfers each day a MS-SQL database from a Windows machine to a Linux installation, and uploads it to the mssql-server with the code below:
...ANSWER
Answered 2021-Apr-25 at 23:58You're already using the -b
flag to terminate the job if it fails. This sets the exit status of that command to non-zero. (A bit like how %ERRORLEVEL%
works on Windows.)
The last command's exit status can be accessed in a bash script with $?

Something like this could work:

QUESTION
ANSWER
Answered 2021-Mar-25 at 15:59From my experience you can only use one ldf per LIN bus. If you have a second bus this one can have another ldf.
Maybe consider to combine the two ldf files into one before importing? The concept of lin with a single master controlling all the traffic should lead to no need of two different description files.
QUESTION
Every week I have to restore 2 different databases. I submit a ticket to Epi support and they give me .BAK files with different dates appended to them.
Running SQL Server 2014 (on remote server), Visual Studio 19 (on local machine), and Integration Service Project.
So far, my SSIS package removes previous .BAK files from SQL Server Backup directory, moves the new ones from my Downloads folder to the SQL Server Backup directory, and deletes one of previously existing backups (I like to delete them because WITH REPLACE does not update the LAST RESTORED DATE and I like to keep those up-to-date).
I would think that I could re-use the filename and the directory from when I move the BAK files with a File System Task in order to generate the RESTORE DATABASE statement, but I am not sure how to pass those fields in SSIS.
Now, I need to EXECUTE SQL TASK to RESTORE DATABASE, but it is hard to execute this in one statement with a dynamic filename.
I have looked at many different articles and tried different things, but none have worked.
The following script is what I want to be able to run, but I get errors even when the filename is hardcoded:
RESTORE DATABASE [Insite.Commerce.horizon.Sandbox] FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\horizon-sandbox-20210412.bak'
The errors that this draws are below:
Msg 5133, Level 16, State 1, Line 2 Directory lookup for the file "d:\sqldata\\Insite.Commerce.horizon.mdf" failed with the operating system error 21(The device is not ready.).
Msg 3156, Level 16, State 3, Line 2 File 'Insite.Commerce.horizon' cannot be restored to 'd:\sqldata\\Insite.Commerce.horizon.mdf'. Use WITH MOVE to identify a valid location for the file.
Msg 5133, Level 16, State 1, Line 2 Directory lookup for the file "l:\sqllogs\\Insite.Commerce.horizon_log.ldf" failed with the operating system error 3(The system cannot find the path specified.).
Msg 3156, Level 16, State 3, Line 2 File 'Insite.Commerce.horizon_log' cannot be restored to 'l:\sqllogs\\Insite.Commerce.horizon_log.ldf'. Use WITH MOVE to identify a valid location for the file.
Msg 3119, Level 16, State 1, Line 2 Problems were identified while planning for the RESTORE statement. Previous messages provide details.
Msg 3013, Level 16, State 1, Line 2 RESTORE DATABASE is terminating abnormally.
I am not sure how to address these errors and/or if they are even relevant because I do not know if I am going about a database restore in SSIS the right way.
Regardless, as of now, I am trying to execute the following SQL statement in SSIS in order to return the SQL statement it generates as a result or variable that can be passed to another SQL statement and then executed. See below:
...ANSWER
Answered 2021-Apr-16 at 16:29WITH MOVE needed to be used, but the DB name changed so all the logical filenames also had to change.
In short, what I did was use the UX in SSMS to set-up the database restore.
I picked my file from my device and changed the Restore To name as necessary. Then, I clicked "Script" in the top left of the Restore Database window and then clicked "New Query Editor Window".
This scripted everything out to a new query. It included the WITH MOVEs that needed to take place and a few other settings.
Although, how I got this to work in SSIS was I copied that new script to an Execute SQL Task in SSIS, but I added that text into another dynamic query that grabbed the filename I needed.
Here is the full query for the restore:
