Restore database from file and reduce datafile while restoring


SQL 2005 Standard.

I want to restore a database from a .bak file. This bak file is referred to a database with fixed size datafile but they are bigger than I need for the new database.

Is there a way to reduce datafile size, during restore process ? I ask this because I will have to do this operation programmatically.


Restore database from system dbs and log file when .mdf file size set to 0KB after Windows Update ?


This can't be right. Friday I tried to install some Windows updates including ‘Security Update for …Windows Server 2008 for x64-based Systems (KB2416473)’ on both my host Server 2008 box and on a VM instance of Server 2008 running on the same physical box. An important SQL Server 2008 instance lives on that VM.


The above mentioned update failed on both the host and the VM, but a system shutdown and reboot were required for both OS’s anyway. When SQL Server started up again on the VM, the *.MDF file size for 2 (out of maybe 15 total) databases had been reduced to 0KB. Additionally, 1 of accompanying *.LDF files was now also 0KB in size, while the other *.LDF file was probably its normal size of 2.9GB. All the other databases and log files, including Master.mdf, seem to be okay.


I’m new to SQL Server and have a couple of questions of cours

An example of packaging web application containing database upgrade SQL file

A few months ago, we have a blog talking about extending the web publishing pipeline to package database project deployed SQL file.  In this blog, I'll show step by step example of packaging web application with SQL Server database upgrade SQL file using Visual Studio 2010.  This way, we can generate a web package with incremental SQL script to certain database version.  The scenario may help distributions of a web upgrade package which needs to be installed on many different locations, each with their own SQL server database.   1. Create a Web Application Project 2. Add a new "SQL Server 2008 Database Project" to the solution 3. Prepare a development database, such as my test1 database as the following: 4.

attempting to restore to a new DB and it keeps trying to save the mdf file as the original mdf file

This is using SQL Server 2005. I've had several problems and this is where I've ended up. 1. Despite the claim that this will create a new DB it doesn't.  I was getting errors about the new DB not having the specified logical file name (despite the new DB not existing).  At the time I was specifying the logical file name as it appeared in the backup. 2. if I manually create the DB I still get the error as above unless I manually change the logical file name via sql management studio.  This is meant to be an automated solution so that is not accceptable. 3. I am now giving it the logical file name of the DB that I want to restore onto (if it doesn't exist I create it), but now it's trying to save the file with the old physical file name, which is absolutely *not* what I want. My instincts tell me I need to change the logical file name in the database I'm wanting to restore onto, but I don't know how to do this via SMO.  All of the explanations I've seen are through the SQL Management Studio and that is not acceptable as this needs to be an automated solution. I have copy/pasted the code from the msdn examples verbatim changing only the dbName and the .bak file location and it has consistently failed. Here is the code in it's current incarnation. var serverName = @"myServer"; var dbName = "MIQDesignTest3"; var backupFileN

SQL2008 - Cannot Restore a new database from a full backup of a different one, database in use

I am trying to restore a brand new database from a copy of another one and am encountering an error message stating: System.Data.SqlClient.SqlError: The file <Backup source database file location> cannot be overwritten.  It is being used by database <Backup Source Database>. (Microsoft.SqlServer.Smo) I am running the Restore procedure with the REPLACE option and am wondering why it is stating that the source database is the database in use when I am trying to restore and overwrite a completely different database. This issue happens when running the replace both in C# using SMO and when manually restoring with SqlServer Management Studio Interesting note is, the original source database is created / deployed using a database project within VisualStudios 2010 and then deployed to SqlServer through VisualStudios. Any thoughts on why this is happening? Thanks in advance for any help!

Error in RESTORE in LOG FILE. Anyway to exclude it?

I'm trying to install a database (on a SQL Server 2008 machine) with test data sent by a partner company in the form of a .BAK file. (Version of SQL Server they are using unknown). I'm using this script: Use Master RESTORE DATABASE XEMS FROM DISK = 'C:\temp\xemstest6-29.bak' WITH REPLACE, MOVE 'XEMS' TO 'E:\XEMS DATABASE\XEMS.MDF', MOVE 'XEMS_Log' TO 'E:\XEMS DATABASE\XEMS_Log.LDF' The Restore process churns for a while, then I get: Processed 2576 pages for database 'XEMS', file 'XEMS' on file 1. Processed 5 pages for database 'XEMS', file 'XEMS_log' on file 1. Msg 3283, Level 16, State 1, Line 2 The file "XEMS_log" failed to initialize correctly. Examine the error logs for more details. Msg 3013, Level 16, State 1, Line 2 RESTORE DATABASE is terminating abnormally. At this point the database is unusable - trying to do anything with it produces an error indicating the database is still in a Restore state. There is some problem with the LOG portion of the backup, which I really don't need anyway. I'd like to just NOT restore the log. Came across this article which seemed to refer to the exact problem I'm having...  http://support.microsoft.com/kb/915385/en-us They offered this suggestion: "Use the WITH NO_LOG clause during the restore process." However - in checking the RESTORE syntax.... http://msdn.microsoft.com/en-us/libr

Single-page restore/recover in an online database

I am working with SQL Server 2008 64-bit (10.0.2531) on Windows Server Datacenter 2008 SP2 (64-bit). The problems I am having almost certainly stem from my lack of understanding of how SQL Server's transaction log is handled during recoveries. I am using this document as a rough guide. Here' what I am doing: 1. I intentionally corrupt a single data page in a normal table, so that I can practice single-page recovery. 2. I attempt to read the corrupt block in SQL. As expected I receive an error. 1> select top 10 firstname from ds2.dbo.customers 2> go Msg 824, Level 24, State 2, Server IP-0AF647E0, Line 1 SQL Server detected a logical consistency-based I/O error: incorrect pageid (expected 4:896; actual 3:0). It occurred during a read of page (4:896) in database ID 5 at offset 0x00000000700000 in file 'C:\sql\dbfiles\cust1.ndf'. Additional messages in the SQL Server error log or system event log may provide more detail. 3. I take a log tail backup before I do anything to try to fix the corruption: 1> backup log ds2 to disk = 'c:\sqlbackup\ds2.bak' with norecovery 2> go Processed 5 pages for database 'ds2', file 'ds_log' on file 1. BACKUP LOG successfully processed 5 pages in 0.041 seconds (0.857 MB/sec). 4. I  restore the corrupt page from backup: 1> restore database ds2 page='4:896' 2> from disk='c:\sqlbackup\ds2.bak' 3> with norecovery 4&
