Hi all,
I have been working on this script all day trying to get it to work.
Just can't figure it out. There are no error messages but nothing happens.
The script was copied of the internet and adjusted for my purposes. I have a large number of database that will have to be created soon. All I will get is a folder with a llot of backupfiles and possibly a list with databasenames .
Any help would be greatly appreciated,

Usually, we backup all databases with a script. Restore is usually per database (as on need). Why do you want to restore all databases? How many databases you need to restore with this script?
Copying from blogs & running it blindly on PROD server is very dangerous. Test your scripts on Test Server first.

Hi,
The databases are for a cloud invironment.
Al large number of customers will have to be created on the databaseserver.
The customerdatabases will be delivered as .bak files.

If it’s less than 20, I would still prefer writing individual restore commands else your approach.
January 11, 2012 at 8:57 am
Actually it os somewhere between 300 and 700

Now I agree with your approach.
Please add a PRINT statement in IF block for debugging and post the results.
IF @@ROWCOUNT = 2

Looking at the restore command itself, logically it makes sense. You're going to have to break down & issue print statements to validate that everything is working. Instead of trying to run the restores, just issue a select statement so that you see all the data coming back and you can ensure that it's correct to fill in the properties for the restore statement. Then try using the data in a single restore statement. Nothing is jumping out as being especially problematic.

Hi ,
Actually I added serveral ' print step(n) ' to the script to see how far it would go.
It stops short of this part:
-- ** -------------------------------------** --
DECLARE @max_rows INT, @Row_Count INT
SET @Row_Count = 1
SELECT @max_rows=count(*) FROM @DATABASES_TO_RESTORE
The piece that procedes it works just fine.
SELECT '25000994', '25000994'
UNION
SELECT '25001905', '25001905'
A select on the temporary database shows the values.
But after this nothing is printed anymore despite the print statements that follow.
cheers,
Cor

Please alter your script with following & let us know the result.
--IF @@ROWCOUNT = 2
IF 1 = 1
January 11, 2012 at 9:25 am
Hi,
Same as before I am afraid.
(2 row(s) affected)
The values in the temporary database are shown. Nothing more.
cheers,

Also, if that insert statement is commented out, you'll never enter the WHILE loop.
January 11, 2012 at 9:32 am
I feel really stupid 🙂
I have been looking at it all day and never saw the insert statement commented out.
Thanks!!
There are some more problems now but I will look at it tomorrow,
Looks like the variable substitution is failing.
Thanks all so far!!

No worries, done it plenty of times myself 🙂
Your set statements are just setting your paths to e.g. '@data_file_path@restore_as@mdf_extension'
Drop all the ' from them and you should be ok.
January 12, 2012 at 12:32 am
Indeed that does seem to solve the problem except for 1 thing:
Msg 8114, Level 16, State 12, Line 103
Error converting data type varchar to nvarchar.
it seems to be here:
RESTORE DATABASE @restore_as
FROM DISK = @full_backup_path WITH FILE = 1,
MOVE 'U4S33_Data' TO @data_file_full_path,
MOVE 'U4S33_Data1' TO @data_file_1_full_path,
MOVE 'U4S33_Log' TO @log_file_full_path
I tried setting @restore_as to NVARCHAR but that didn't work.
I then added these satements to the script
print @data_file_full_path
print @data_file_1_full_path
print @log_file_full_path
Results:
D:\Data\25000994.ndf
D:\Logs\25000994.ldf
The first SET statement is not shown.(.mdf file) So I think the problem is there.
Cheers,
Cor

It turned out there was a typo in the
SET @ndf_extension = '.ndf' statement.
everything works now
Thanks to all for your help!
Much appreciated!
Cheers,
Cor
