I recently had to find ways to programmatically backup and restore an
SQL Server Express database.
For backup, I found a one-liner stored procedure that does the job
(BACKUP DATABASE Toy to disk = 'c:ProjectsToy.bak'.
My question is, is there something as simple for a restore operation?
Thanks in Advance

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.
I've seen several post asking for that possibility, but all 've read, didn't help me.Some sing SQLDMO, other suggest to use SQLSMO, others only explaining to connect to a server and then do "CREATE DATABASE".I will do this within .Net. Connecting to a SQL Server 2005 and execute "CREATE DATABASE" I could realize.But how doing this with SQLExpress? Trying to do SqlConnection.Open with a non existing DB does not work., says "file not exists".Or do I only have the wrong connection string? Can someone post here an excample connection string, which works with a non existing database?Some hints I've read make me considering to use SQLSMO. But I don't have it on my computer. Where do I get it from? Any links would be nice.

Is the any easy way to clone a database programatically?
I've searched the web but did not come up with anything.
At the moment I create a new blank database (based on the model database)
and create tables, indexes, etc. via asp. (The databases are always exactly
the same)
It seems to me that it would be a better option to
create one database with tables, indexes, etc and copy
it to a new database (on the same server).
One of the options I'm considering would be to create a database,
fill it with tables and indexes, etc. and then detach it.
Whenever I need a new database all I would have to do is use the
file system object to copy and rename the mdf file and then reattach the
new mdf file.
I realise that I could also make the changes to the model
database so that all new databases have the same structure
but that would be my last resort.
Is there any easier way to do this? A stored procedure perhaps?
You're opinions and advice would be welcomed.

I know how to set up SqlDataSources and their insert, delete, update, and select commands. I also have code for querying a Sql table and populating a dataset and scanning the dataset for values. However, I do not know how to modify records in a Sql table programmatically. Here is what I need to do:
I need to open a Sql table.
I need to process record bny record to check a particular field for a particular value.
If the field has the particular value, I need to change it and write the record back to the table with the modification.
The table is named "SystemUser" and the field is call "SystemUserTypeId."
Can anyone provide me with sample code that would accomplish this? Thanks for the help.
I have seen this before. A 2000 restore fails, leaving the database thinking it is being restored but the restore job failed and errors when it is restarted. EM is clueless. I believe there is a proc to reset some flag. Can you share it with me???
Thanks!
Hi all
this is my code and i find it in microsoft's site
if i run it with sql server connection it works but if i try to use it with sql express it give me this error:

I'm trying to compact a SQL CE database programmatically. I've copied the code from MSDN, and it's fine as far as it goes, but there's a problem tying to compact a database in a ClickOnce application because you don't know the path to the database. You have to use the "|DataDirectory|" in your connection string to signify the path to the database. But when I try the file operations to replace the old database with the compacted version, I get an error message that the path "|DataDirectory|" is not valid. Here's the code:
SqlCeEngine engine = new SqlCeEngine("Data Source = " + src + "; Password =" + txtPassword.Text);
try
{
engine.Compact("Data Source = " + dest + "; Password =" + txtPassword.Text);
ShowMsg("Compacting...", MsgType.NoError);
}
catch (Exception ex)
{
MessageBox.Show("There was an error completing the operation: " + ex.Message);
}
engine.Dispose();
File.Delete(src);
File.Move(dest, src);
(dest is = src + ".tmp", i.e., a path to a tmp file to hold the database while compacting).
How do I locate the files to copy if I can't use "|DataDirectory|"?
Hi Guys,
I was wondering if there is a system procedure / T-SQL code to programmatically Failover a Database from Principal to mirror mode?
also,
We noticed that at times few of all the databases that were kept on 'Principal' mode get randomly 'Failover'. Does anyone have any idea?
If so, pls respond.
Thank you.
When my app starts up I want to ensure that the database compatibility level has been set to 90. I know about sp_dbcmptlevel, but that only seems to work in an interactive session; the documentation says it can't be used in a stored procedure, and that appears to be true. Does anyone know how I could read the database compatibility level in a stored proc?

View 7 Replies View RelatedRecently we had multiple production failures because one database was in single-user mode. I am trying to recreate this scenario to write a script that will kick out that connection that was holding database in single-user.In SSMS window 1 I run the following code:
use master

Yes, it shows one record, but the database name is master, not test. And indeed, I run it from the context of master. Also tried sp_who, sp_who2, sys.dm_exec_requests - nothing works. For dm_exec_requests it shows nothing because it does not run at the current moment.Any other solutions to catch this SPID with a script?

Trying to keep out sysadmins & sa during/between database RESTORE
Configuration:
WINNT Server Enterprise 4.0 w/SP5
SQL Server 7 Enterprise & SP1
2 SQL Servers:
Production Server
Standby server
I Backup (full backup) databases to disk on primary server (logical backup devices are physicaly located on a Standby server (dedicated gigabit NIC in each server for this process). Transaction logs are applied to the Standby server throughout the day.
Problem:
How to keep out "sa" and sysadmins from a database while I'm restoring (or between restores) to a standby server?
The database being restored cannot be in use during a restore.
If a DBA forgets that this process is happening, the statement fails (RESTORE)for the database they happen to be in at the time of the restore.
Example restore statement:
Standby Server -
RESTORE DATABASE databasename FROM database_dd WITH DBO_ONLY, REPLACE, STANDBY = 'g:Mssql7FromPrimaryDatabaseName_undo.ldf'
I could restrict Domain sysadmin access and change sa password. I could also put the database in "Single user" mode, however this could become problem if my process disconnects and then someone else connects - then my process is locked out. What I'm really looking for is to lock out all activity for a database that is in "standby mode" except for RESTORE processes.
Any ideas??

I'm taking a database(read-only) backup from one server and restoring it on other server. As soon as restore is done it is bringing database into single-user read-only mode.
why it is bringing the database into single user mode ?

View 2 Replies View RelatedAnybody figure a way around this:
In a development server you take a backup and you want to move the entire database to a production server. The production server does not contain the database, users, or logins in master.
When you restore the backup to production in 7.0, the users get moved to DBO because the logins do not exist and then you cannot delete them.
We are having to drop the users from the database on development, back up the database and restore it to production, then recreate the users on production.
This is bogus and did not happen in 6.5 because of the aliases.
Anybody come up with a better way?
I am fairly new to VS 2005 and SQL Server CE. I have developed a Desktop Windows application using VB 2005 and the SQL Compact Edition Database. This application will sell to users via web download.
When they download a service patch, or updated version, I wish for them to retain the data in their present database. In other words, fill the new database with the old data. The new table structures will remain intact except for added columns at the end.
Question is how to save the old data and update the new database with it. Is there an easy way to do this, or do I need to write a module to save a database copy, and update the new database with content at install time?
I have a problem when i restore my .DAT_BAK file. I am getting error like "The backup set holds a backup of a database other than existing database. Restore Database is terminating abnormally".
I tried by using
RESTORE DATABASE <DATABASENAME>
FROM DISK = 'D:DATAMYTEST.DAT_BAK'
WITH MOVE 'VZAI_DATA' TO D:PROGRAM FILES..MSSQLTEST.MDF',
MOVE 'VZAI_LOG' TO D:PROGRAM FILES..MSSQLTEST.LDF',
REPLACE
And also i tried like
RESTORE DATABASE <DATABASENAME>
FROM DISK = 'D:DATAMYTEST.DAT_BAK'
WITH REPLACE
When i use like this,
RESTORE FILELISTONLY FROM DISK = 'D:DATAMYTEST.DAT_BAK'. I am able to get the output as LogicalName, PhysicalName, Type, FileGroupName, Size, etc.
Can i anyone please help me out?

Sometime during the night last night some user account permissions were "lost". Am I right to think that restoring the master database would be the way to go? We have a 2 node 2012 cluster and I stop the cluster resource and start the db in single user mode from the active node. Somehow the sharepoint farm is still trying to connect so I can't get logged in single user. What method could I use to stop users from connecting when I don't have access to the sharepoint farm.
View 8 Replies View Relatedi have a development database that has updates and changes to a production database. rather than go through individually and alter all relevant tables and stored procedures, id like to back up the database on the development side and restore it on the production side as the production database. is there a way to restore the database on the production server but preserve all the security settings (ie logins and such)? i noticed on our development server, that if i try to restore the database with my development database, it overwrites the users and/or if the user is the same on both, it removes the login name for that user.

I have a client that has POS software called Restaurant Pro Express (RPE) from [URL] ...
Their old POS computer had a hardware failure, but I was able to attach the hard-drive to another computer and recover the data. RPE uses a MSSQL database system. However, my client doesn't seem to make backups very often
- the last one is dated January 5, 2015. I was able to copy the C:Program FilesMicrosoft SQL Server folder over which contained the instance as well as all the data files - and has up-to-date information. The instance in the recovered Microsoft SQL Server folder was called MSSQL.1. I installed the RPE software on their new computer, and it too now has an instance called MSSQL10_50.PCAMERICA. The new computer is using MSSQL 2008 R2, while I believe the old computer would have been using MSSQL 2005.
I am no DBA expert, especially when it comes to MSSQL. Is is possible to 'restore' the database from the 'raw' .mdf and .ldf files of the old computer to the new computer / database instance? If so, how should I proceed?
I had a major disk failure, and the only SQL Server files I was able to recover were master.dat, msdb.dat,msdblog.dat, two text files and two database devices. My question, is it possible in SQL 6.5 to restore a database from just the database device, and if so, how? Thank you.

The data in one of the tables in my datables got deleted.
I want to restore my database to an earlier time, but don't know how.
I'm not sure if I have any backups, I wasn't making any myself.
All I have is the ldf file, but I don't know how to open it or what it contains.
On a test server I had deleted the .MDF to testdb, before deleting the .mdf
I had backup the database inserted some records into a table and then backup
the transaction log.
I brought the server down and back up then did the following:
use master
go
BACKUP LOG test
TO TestRestore_Log2_Backup
WITH NO_TRUNCATE
GO
RESTORE DATABASE test
FROM Test_Backup
WITH NORECOVERY
GO
RESTORE LOG test
FROM TestRestore_Log1_Backup
WITH NORECOVERY
GO
RESTORE LOG test
FROM TestRestore_Log2_Backup
WITH NORECOVERY
I receive all kinds of errors like:
Primary file not available for database 'test'
( i'm sure that's because the .mdf is gone),One or more devices or files already exist use REPLACE, Which is fine but when I do I only get the full back and not the latest transaction log?
I was restoring a database from a backup I had made about a month ago and it gave me an error. I don't remember what it said exactly, but I know that it had to do w/ restoring the transaction log. Now, I can't access the database at all. When I try to access it through enterprise manager, it says "An error occurred while trying to access the database information." If I try through Query Analyzer, it says that the database is in the middle of a restore. I checked the sysprocesses table and there is nothing running against this database.
Is there anyway to recover this database, or am I going to have to recreate it from scratch. Please tell me I can recover the database!!!!

I have 2 servers SQl server 7 and 2000.
I got a backup file from the customer for one of the database. So I created a new database using similar script as below
create database TESTUP
ON
(NAME = TESTUPDATA,
FILENAME='C:PROGRAM FILESMSSQL7DATATESTUPDATA.dat',
SIZE=10GB)
LOG ON
(NAME = TESTUPLOG,
FILENAME='C:PROGRAM FILESMSSQL7DATATESTUPLOG.dat',
MAXSIZE=500MB)
GO
sp_addlogin TESTUP, TESTUP, TESTUP
GO
USE TESTUP
GO
sp_adduser TESTUP
GO
When I use enterprise manager to force restore that backup copy to this database I just created, even though I have setup maxsize for LOG as 500 MB it still gets all their logs 50 GB !!! I do not want their logs in the 1st place and then I tried to restrict them I could not do so.
So I restored it as it was urgent and then tried to shrink the datafiles for LOGS but they did not shrunk much.
Is their any way to avoid getting the transaction logs during the restore ???
In other words can just get the datafiles and not the transaction logs ?

I have a database that was not backed up and needs to be restored after an os crash. SQL was stopped gracefully and the server was rebooted, the os crashed and was reloaded, now sql is installed and I need to know if there is a way to restore the .mdf and .ldf files to the sql server.
