Reliable Method Of Restoring Over Existing Database
Dec 29, 2007
I have a process that restores a backup from a primary server to a backup server daily. When doing the restore, sometime it fails (for various reasons).
I have coded a job to Set offline, set online, an then do the restore:
RESTORE DATABASE [xxx] FROM DISK = N'D:Backup Stagingxxx.bak' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10
Sometimes it fails to bring back online, other errors as well. Is there a reliable method of doing this?

Hi All,
I would like to restore database using RESTORE DATABASE ... REPLACE command.
If database exists already and has any open connections this command will fail.
I would like to close all existing connections to specific database before running RESTORE DATABASE ... REPLACE command.
I can do closing from Management Studio using checkbox "Close Existing Connection" when deleting database. Actually I need to do the same but from script.
Please advice me how to do it.
Thanks in advance,
Roman

Hi,
For this scenario, what is the best method of exporting data to sql 2005.
I want to export data from desktop app across internet to sql which can do on a row by row basis, but this is very slow and if the connection goes down halfway then pretty much buggered.
What is the best, reliable and fastest way to copy data across internet (several thousand rows), I have read about Bulk Insert etc... but also how would get around an upload and crashes half way, is there a way of uploading and until the whole upload goes through then the data is inserted into the database.
Would appreciate any guidance.

I need to recover some data in a table but i'm not 100% sure the right way to do this safely.
I'll need to query the two tables to compare the before and after but how do i go about restoring/attaching the backup database to SQL without causing conflicts?
If I restore, i assume this would just overwrite which is obviously the worst thing that can happen. If i attach the backup, how does this affect the current live DB? how do i make sure that it's not getting accessed and mistaken for the live DB?
The SQL server is 2008 R2 running as a VM.

I want to restore a database (from an encrypted .bak file) - but *not* over the live original if you take my meaning. Encryption is the standard AES-256 that comes with Sql Server 2014 btw. I don't want the original touched/altered in any way. I would like to capture a success message if possible.I can extract the physical device name of the database in question using the following code:
SELECT physical_device_name, *
FROM msdb.dbo.backupmediafamily
WHERE media_set_id =(SELECT TOP 1 media_set_id
FROM msdb.dbo.backupset
WHERE database_name='MyDatabase'
AND type='D'
ORDER BY backup_start_date DESC)
I would like if the newly restored database was rename to something different than 'MyDatabase' (as shown above) and has different logs than the original. If possible, and capture a success message when restored.

It may sound like crazy question, But just curious to know if any one tested this scenario.
I was restoring an existing database from a backup. While the restore is in progress, I found i was restoring with old back, then I canceled the operation.
Now Will it restore the partial data or it rolls back the entire transaction and brings back to original status or it will currupt the database??

My question is two fold. First, What is the best method for mirroring to a fail-over server? Replication has limits on tables that do not have key fields, and I am finding that Log Shipping is harder to work with.
I have set it up several times, and conducted tests with test databases, but when it fails, I get no indication as to why, and I also can find no way to re-initiate it (without deleting the maintenance plan and starting over). Which leads to my second question, is there a way to manually initiate a log shipping plan already defined?
Thanks in advance!

I am using MS SQL 2005 Express. I have a database with two filegroups, the PRIMARY default filegroup, and then filegroup X. I have a backup of the PRIMARY filegroup only, and am trying to restore it to my database. When I select the .bak file to restore from, I am NOT given any 'backup sets to restore' - I therefore cannot select the filegroup to restore it. Can anyone advise? (NOTE - I have backed up the transaction log on the database I am restoring to already)
Thanks

I did a full backup of a db from one server(Express2005) and trying to restore it to a different instance of SQL2005 on the same development machine. (Also had some fulltext columns if that means anything)
Many failures but finally got it to report all was successful except the icon in Object Explorer shows (Restoring...) with no indication of any real activity going on. It's a tiny database with hardly any data in it.
Just not sure what the heck is going on there. It also won't let me into the database until this the (Restoring...) goes away.
Any advice on how to get this thing finished out?

SQL 7.0I have a form in ASP.NET and I want to write the values to the SQLServer tables.The tables are Customer and Address tables.There will be an insert into the Customer table, and I need to use theIdentity of this inserted record for the Foreign Key in the Addresstable insert.For exampleINSERT INTO Customer (CustomerName)VALUES (@CustomerName)Select @@identity as CustomerIDINSERT INTO Address (Address, CustomerID)VALUES (@Address, CustomerID)My question is this. If I put this into a single stored procedure canI absolutely GUARANTEE that the @@identity value will be from theCustomer table insert, or could it feasibly be from another, as itwere, colliding operation?TIAEdward--The reading group's reading group:http://www.bookgroup.org.uk

How reliable the SQL Compact 3.5 is?
What I need is to make sure that in case if my Windows CE based device lost power supply my SQL Compact 3.5 database will not be corrupted and I can read data from it.
Has anybody any experience in this area?
This is critical requirement for our project and I want to know it is feasible or not.

Hi..
I have a SQL Server 2005 Database .. I develop for the customers a C# Application , that sends some specific Information to my central Database.
If I would create a connection over tcp/IP (in order to send data to central database) like
sqlconnection1.ConnectionString = "Data Source=192.XXX.Y.ZZ,1433;Initial Catalog=Muster;Integrated Security=True";
it would not be reliable. How can we make that safe?
Thanks...

I have set up two Maintenance Plans to do daily backups overnight for our two DBs that are on our SQL server.
As a separate strategy we want to have a second backup done nightly that would involve
#1 detach the db(s)
#2 copy the mdf(s) and ldf(s) to L:xxx
#3 attach the db(s) again
#4 zip up the db(s)
#5 copy the files to a different server for storage.
I created #1, and #3 in query analyzer and saved the script.
I want the process to run at say 2AM and don't know how to schedule them to run - that is #1 ... #2 ... #3. Anyone have sample scripts for this kind of a backup strategy?
This seems like a very simple process especially for a restore and especially since there would not be any trasaction logs involved. This way if we had a KRASH we could take the backup from the separate server and install it on a warm SQL backup server.
Apart from the new servers name then what other steps would I need to cover to get the apps up and running in the quickest time. The app software runs as a client install - Access 97DB] I'm especially curious if I need to have more than a fresh MS2000 SQL server install.
I'm know I'm asking a lot for a first timer.
It seems we want to handle disaster recovery BEFORE we even have our first system crash.
many thanks

Maybe I am just a lot better at this than I thought, but I figure that somewhere there is a mathematical rule that is being overlooked. When I run dbcc sqlperf (lrustats) on some of my production machines, I sometimes end up with a cache hit ratio (which is defined as a percentage, mind you) that is slightly over the limit:
Statistic Value
-------------------------------- ------------------------
Cache Hit Ratio 100.00898
Cache Flushes 0.0
Free Page Scan (Avg) 0.0
Free Page Scan (Max) 0.0
Min Free Buffers 331.0
Cache Size 4362.0
Free Buffers 9434.0
I suspect some counter somewhere is getting wrapped around its 4 byte limit. Is there any reliable source for getting statisics about SQL Server performance? Users tend be unreliable and say everything is slow.

Hi-I have a sql server database, and am wring web apps to access it.I've created databases different ways, and ended up with different owners (eg dbo, nt authorityetwork services...)I also have connection strings using windows authentication, and some using a user name and password.I have read that using windows authentication is the best way to go, as far as security goes, but I have noticed some connectivity issues when I upload the site to the server, and test it remotely. What is the safest 'owner' of the database, and what's the safest way to connect?Thanks Dan

I have been tring to get this one line figured out for a few days now.
'Job2 Info
Dim selectSQL2 As StringselectSQL2 = "SELECT * FROM '" & CompanyKey & "'" '<<-------HERE
Dim cmd2 As New SqlCommand(selectSQL2, con)
'Job2 Select
Try
con.Open()
reader = cmd2.ExecuteReader()
(I have the full code below.) So here is the problem, this code is not populating the datagrid. There is data in the table I am selecting from. When I log in, my CompanyKey value displays in the label as "21". When I take out the "CompanyKey" variable, and just type in 21, the grid is populated. It is confusing the heck out of me. I have tried it this way:
selectSQL2 = "SELECT * FROM [" & CompanyKey & "]"
-and this way:
selectSQL2 = "SELECT * FROM & CompanyKey
and all the other ways I could think of. I researched it and can just not get it to work any way I do it. Any suggestions? Full code below:

I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.

Hi, My server went dead(problems with the hard disk), but I have a copy of the whole sql server directory including the database in a external hard disk. I have a new server now and I would like to copy this database (with the reports from reporting services too) from the external hard disk to my new server. can anybody help me please? Thanks.
Note : I have a plain copy of all the sql server directory with all the files including the database not a SQLServer backup done with the wizards.

Hi guys,
I've been assigned the task of setting up access to our SQL Server 2005 box. A consultant developing for us has accessing to 2 databases and I've set this up fine. It appears however that one of these databases is re-copied over to the server every night to keep data reasonably current.
I'm not interesting in changing this method as I'm not the maintainer (as yet).
Basically I would like to know if I've setup access to this database (it works fine), when the database is updated (with an SSIS package) the account seems to get deleted. Do the original permissions from the source database overwrite those of its destination?
Cheers

I posted a more detailed technical question a couple of weeks ago
with Subject = "Compact Edition 2005 Subscribers - Merge Agent failed after detecting that retention-based cleanup has deleted metadata"
But I got no replies.
Now my question is simpler: Is SQL Server 2005 Merge Replication reliable with Compact Edition subscribers on WindowsXP tablets?
We deleted all users' local databases a couple of weeks ago, and republished two publications with retention = 60 days.
Now we have at least one user who can't sync with the server, and replication monitor shows the error below.
But if she e-mails her sdf file to a support person, they can successfully sync her database.
We're sure that it's not a permissions issue, which is a normal suspicion when one user can perform a task that another can not.
It doesn't seem like a retention problem, because she's well inside the retention period.
She can successfully sync with the publication with upload/download tablers, but not with the publication with download only tables. Both publications were created on the same day, by the same DBA, with nearly identical properties.
This problem user has operated in the past with no problem, and she's configured identically to all of the others. It just seems like random flakyness with merge replication for Compact Edition subscribers.
I feel stupid saying that, because it sounds like I believe in a magical ghost in the machine. So my question is - IS MERGE REPLICATION A LITTLE BIT FLAKY FOR COMPACT EDITION SUBSCRIBERS ON XP MACHINES?
We've applied SP2 to the server, but no subsequent HotFixes.
We're trying to sell users and management on developing a larger occasionally connected system with the same replication scheme, so we need to know if it deserves our confidence.
Error messages:
The Merge Agent failed after detecting that retention-based metadata cleanup has deleted metadata at the Publisher for changes not yet sent to the Subscriber. You must reinitialize the subscription (without upload). (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199402)

I am new to sql and my boss want me to write the program for database and he wants to pull the info from existing table from sql server which is used by Microsoft GP Dynamics and write me code or some kind of front end so when he wants he can pull same data from GP dynamics table and generate some report with other custom table.
How i can do this task? What I have to do in sql so I can use same table to view info in real time so that means if i enter new data in the table it will show up same time in the front end as well.

Hi,I have a table which I need to store times in. What is the best way of doing this? The only way I can think of so far is to save the times as a datetime such as '1/1/1900 03:00 PM' then format the date as "hh:mm tt" so that the day isn't displayed. Is this the best method?Thanks,Curt.

Lets assume database A is production, B is copy. SQL Server 2005 sp2, SQL CE 3.5
Database A has a variety of transactions against it 24x7
Database B (the copy) is for reporting and as a source of merge replication for SQL CE instances
Merge replication and reporting is used 24x7 as well
I have the following requirements:
Maintain an up to date copy of the production database (need not be up to the minute, could be hourly, even daily update)
Database B is read-only. The merge replication is NOT bi-directional.
Here is the caveat (which I think prohibits using some solutions to this problem):
The production application accomplishes much of it's functionality with in-memory copies of records. I have no control over the production application. When it works against the database, it sort of does a 'withdrawal-deposit' scenario. (to the best of my knowledge it's not using SQL Server transactions) So, for every record it works with, a copy is made out of the database, changes are made in memory, a delete of the database record is done, then the record is re-inserted.
With this kind of behavior in db A, I'm not sure what it would do to log-shipping or transactional replication. I do know that I want to minimize the changes required at the SQL CE instances to keep the sync operation to a minimal cost.
Any suggestions?

I have a table that is corrupted and want to remove and add a backup version of it. How can i remove this table and add it again preserving all the foregin key restraints, permissions, dependencies, etc? Simply exporting and importing does not work. I could painfully remove the table and then painfully reconnect it again, recreating all the foreign key restraints, etc, by hand; but there has to be an easier way! What is the How-to?
Thank you!

I wanted to set up a mechanism that would transfer blocks of records (a few dozen to in rare cases a few thousand), with slight modification, from one database to another. It's a sort of custom partial archiving process that would be triggered from a web-based admin application in plain old ASP (not .net alas). Records in the target db would be identical except:
-- the primary key in the source table, an identity field, would be just an integer in the target table
-- the target table has an extra field, an integer batch ID supplied by the web application that triggers the process
It's a simple, if not efficient matter to do it within the web application: query the source table, suck the records into memory, and insert them one by one into the target db. This will be an infrequent process which can be done at off-hours, so a bit of inefficiency is not the end of the world. But I wondered if there is a more sensible, orthodox approach:
-- Could this process be done, and done efficiently, as a stored procedure with the batch ID passed as a parameter?
-- Is there any way to do a bulk insert from a recordset or array in memory using plain ASP, ADO and SQL? And if so, is that better than inserting records one by one?
I realize that the ASP.NET tableadapter and dataset features might provide a good solution, but in the short run I can't rewrite the whole application. Advice on the best general approach from an ASP-ADO platform would be appreciated, and I will try to figure out the details.

I have a Subscriber database updated using transactional
replication and want to create a copy for development & testing. The Distribution database is running on the
same 2005 instance as the Subscriber and the Publication database on another
server running SQL Server 2005.
If I use a TSQL script to run the restore, the database is
restored to a usable state but I get the following messages:
Msg 15247, Level 16, State 1, Procedure
sp_MSrepl_check_job_access, Line 112
User does not have permission to perform this action.
The replication agent job [job name] was not removed because
it has a non-standard name; manually remove the job when it is no longer in use.
(I€™ve removed the job name from the message)
RESTORE DATABASE successfully processed 46219 pages in
935.413 seconds (0.404 MB/sec).
It looks like an attempt is being made to restore
replication information too. I note that
the RESTORE statement has a KEEP_REPLICATION options which implies (I would have
thought) that by default the replication information is not be restored.
Incidentally, before implementing replication, backing up
the live database and restoring the backup to a new database took < 7
minutes but running the same process with a Subscriber database backup takes
about 15 minutes.
I€™d be interested to know if anyone has any idea what I€™m
overlooking or doing wrong.
ThanksTim

I have made a small asp.net project which uses a local database file as a part of the project. The project is running fine om my local machine, but when I upload it to the remote server, the login fails for the server.
I suspect this is can be solved by using sqlserver authentication. But I have now spent a lot of time trying to configure the database file to use this authentication mode. As I see it there are three possible solutions to the problem.
use management studio express to configure the local mdf file (Ecxept that I cant find out how to connect to the mdf-file) and from here change the authentication method to sqlserver authentication.
use Visual Web developer to change the authentication method (but how???)
make the windows authentication work on the server (this would probably require that mannamgement studio express connects to the remote database. (Same problem as no 1)
Help will be higly appreciated.

1) We have got the database dump (.bak) file in one machine and we need to restore this to another machine where the SQL server (version 7) is running. But in the restore option there is no way to choose any mapped or shared drives in remote machine. Any pointer to resolve this problem?
2) Can you set up a database if you have the .mdf and .ldf files?
