i have a backup from a data base (SQL Server), i never worked with this type (always with MySQL and PhpMyAdmin to see the data). How can i see the data who is inside the backup? there is a Microsoft program to do that? like access.
Using SQL Server Management Studio, you use Restore feature. The process is laid out in the MSDN documentation.
Obviously, you restore to another SQL Server database instance. The version of the instance can be newer than the version the backup came from - the compatibility level will just be set accordingly.
depends whether you want to pay for the solution ;)
If you have the disk space and don't want to pay then you have to restore the backup.
If you dont have the disk space, and/or don't mind paying and/or you only want to restore a certain subset of the data you can use quest software's litespeed http://www.quest.com/litespeed-for-sql-server

On my development box, I always run the latest version of SQL Server. I often deploy databases from my dev box to a live/staging area for review or testing. I've done this many times and it has always been a painful process, but I am realizing that I need to find an easier, more reliable and consistent way of performing this basic operation.
I normally use WebMatrix purely for deployment and it's worked fine, but I've been having problems getting it to work on my server for some reason. Consequently, I am seeking an alternative solution.
Creating a SQL dump file would probably work, but it's not an acceptable solution a database contains images and easily exceeds 2 gigs of data which would take forever.
The Import/Export utility fails due to issues with incomplete schema copies, identity inserts and checks. The solutions offered for these issues has failed to work in my particular case.
The Backup and Restore method also fails due to some strange incompatibilities between SQL Server 2008 and 2012. SQL Server 2008 Management Studio throws exceptions during the restore process of a 2012 database. It's odd that this happens, even though I set the compatibility of the database to version 2008.
I haven't tried the Detaching, copying and reattaching files method, but I haven't bothered trying since it would probably fail for the same reasons the backup and restore method did.
Are there other alternatives out there? Also, why is this so unbelievable hard for a task that is so common and important, especially in this day in age of 2013? Get real Microsoft!
We changed our method of deploying and moving databases between servers, instances and versions by adopting the tools from RedGate. They are expensive, but worth it IMHO.
My team creates scripts for ~everything.
Database Creation, Alter, Inserts, etc, etc.
And we write all scripts that check for the existence of things before trying to create them.
Aka, we can run the scripts over and over and get the same results.
And we deploy to different environments by using SqlCmd.exe.

=============
If that is "too much" then I agree with the other poster, RedGate is your friend.
Points below aside, have you considered the Database Projects within VS2012? they allow you to script off the tables, sp's, triggers, users etc you want, generate sql cmd scripts, make changes and schema compare and version control your database code, I'd certainly recommend it
"Creating a SQL dump file would probably work, but it's not an
acceptable solution a database contains images and easily exceeds 2

Why is this a problem? where are you transferring the file from and to and over what connection?
"The Backup and Restore method also fails due to some strange
incompatibilities between SQL 2008 and 2012. SQL 2008 Management
Studio throws exceptions during the restore process of a 2012
database. It's odd that this happens, even though I set the
compatibility of the database to version 2008"
This shouldn't be an issue if file is created in 2008 prior to restoring. If you create a new DB in your 2008 instance, then take a backup from that and restore it to a 2012 instance with 2008 compatiblity, then you should be able to use it there, back it up from the 2012 instance and restore to 2008 again afterwards.
I am installing a service pack on our shopping cart. They recommend backing up the SQL database before installing. I know we have backups to tape drives done by our hosting company, but I want one I know the exact time stamp for and can access quickly if I need to reload it because of a goof during the upgrade. (I don't want to have the store down for any longer than needed.)
How do you recommend backing up a SQL database for easy reloading for someone who is used to just writing queries and stored procedures? (I'd like to get everything - mappings & indices, etc - because I wouldn't know what all of them are or how to recreate them.)
I access the database via Remote Desktop and can link my hard drive and DVD drives, if that helps. It's MSSQL 2008.
Thank you so much.
Best wishes,
Andrea
BACKUP DATABASE databasename TO DISK='C:\somefile.bak' WITH COPY_ONLY, INIT, FORMAT, CHECKSUM
Obviosly replace databasename and the target C:\somefile.bak as appropriate. Remember, the file and path is on the server; connecting remotely won't change where backup file is stored--in other words it won't be on your local machine.
You can omit the WITH options if you want. Drop INIT if you don't want the target .bak file overwritten. COPY_ONLY isn't a big deal either way in your case. CHECKSUM is just for validating the data before it gets backed up, and may not matter if you don't have CHECKSUMs turned on for the database--though by default starting in MS SQL 2005 new databases were.
The MS documentation for BACKUP and RESTORE isn't too difficult to understand in its basic forms. You can also use the Management Studio Tasks->Back Up or Tasks->Restore GUI if you have access to it.
I want to copy all my database to remote database server. I have access to server using SQL server management studio.
How can I do this? I have created script with data of old database and tried to run it on new server but it is taking too much time and returns different errors like duplicate key etc.
If this is a one time deal, you should download Redgate's SQL tools. They can handle this easily and are free to test for 14 days I believe. (http://www.red-gate.com) You might even find they are worth the purchase as I have. The tools you would use are SQL Compare (to copy structure) and SQL DAta Compare to actually copy the data.
Assuming that you can restore databases to your remote SQL server, you can use SQL Server backup and restore? They're available in SQL Server Management Studio. See http://msdn.microsoft.com/en-us/library/ms187510.aspx. It's very easy to use.
Other than that, you can try copying the database MDF and LDF files from your local database onto your remote database filesystem, then attaching to the MDF file on your remote database.
Those are probably the fastest ways that you can copy and entire database to a remote location that I can think of.
Try Database publishing wizard by Microsoft. Good enough for no very big data amounts.
I have a live database on a shared hosting server. I am making some major changes to my site's code and I would like to fix some stupid mistakes I made in initially designing the database. These changes involve altering the size of a large number of fields, and enforcing referential integrity between tables properly. I would like to make the changes on both my local test server and the remote server if possible.
I should note that while I'm fairly comfortable with writing complex queries to handle data, I have very little experience modifying database structure without a graphical interface.
I can access the remote database in the visual studio database explorer but I can not use that for anything other than data manipulation. I installed Sql Management Studio express last night and after 40+ crashes I gave up - I couldn't even patch the damn thing.
The remote server is SQL 2005 / The MyLittleAdmin web interface is available.
So my question is what is the best way to accomplish these changes. Is there a graphical interface I can use on the remote server? If not is there an easy way to copy the database to my local machine, fix it, and re upload? Finally if none of the above are viable does anyone have links to a decent info on fixing referential integrity via query?
Sorry for the somewhat general question - I feel like I am making this far harder than it should be but after searching / trying all night i haven't gotten anywhere. Thanks in advance for the help. I really appreciate it.
...Also does anyone have a time machine I can borrow- I need to go kick my past self's ass for this.
Usually hosting providers allow you to backup and restore your database, so the easiest way to accomplish the move is to backup your live DB, download the backup file, restore it locally, do all the changes, do a backup of the local db, upload it, then restore it in the live service. Your site should be placed on an administrative shutdown during this time so it does not continue to update the data while you're doing this operations. You have to make sure your local SQL instance is exactly at the same build version (##version) like the hosting provider, otherwise your local SQL may upgrade the database structure and you'll be unable to restore it back on the hosting provider (or you'll be unable to restore in on your local server if your version is earlier than the host's). The MSDN BOL has a detailed guid on how to Copy Databases using Backup/Restore.
An alternative to backup/restore is to detach/attach the database, but I do not recommend this because you need to move both the MDF and the LDF in sync, and they're also larger in size than a backup.
This assumes you can do all the schema changes on your local copy in a wizardly manner, ie. fast and correct. Of course, that is not easy. The recommended way is to prepare in time a script that applies all the transformations needed to reach the new schema. There are tools like SQL Diff, SQL Compare, SQL Delta and other that can generate such a script. Also Visual Studio Database Edition can do this.
How I would do this would be like this:
Ensure I have exactly the same schema on my dev machine as on the live host. If not sure, I can take a backup of the live server and restore it localy. This would be my reference, v1. schema.
Keep the backup of v1. for reference
Start developing a script that changes the schema to my target. Sometimes I need to refresh my memory on script syntax myself, and what I do is I go to the SQL Server Management Studio wizards for the operation I want to do, select all the options in the UI and then select the 'show script options', that will show me exactly the script SSMS is running to accomplish my desired change.
For each change I add to the script, I can test it by restoring the v1. reference backup I have from step 1 and running the script.
Keep iterating on the script, adding one change at a time, until all the needed schema changes are done. After each change, I can test it again like in step 4.
Yourscript should do not only DDL changes to the schema, but also any DML changes needed (modifying reference data, changing values, moving columns between tabels etc).
When the script is ready, I can download a newer backup, apply the script, and upload the updated backup and restore it on the live host. Alternatively you can simply run the script on the live host (after of course you backed it up in case something goes horribly wrong).
In my projects I always rely on scripts to deploy and upgrade the database. In fact I use the database extended properties to store a 'version' of my application deployed schema and in my code I simply roll forward all the scripts that bring the schema to my last version. I have an article on my blog describing this technique: Version Control and your Database.
So at work, my team is using a central SQL server 2005 database server for integration testing and I want to move to testing on my local database. The only problem is that the central database is in excess of 10 Gb.
I am interested in importing the data objects and a rows for each table to ensure I can be up and running. Can you guys advise me on how I can do this?
I have VS 2008 professional and SQL Server management studio express. Would I need VS 2008 database edition?
Thanks
-Venu
EDIT : I will try logging into the central database server and seeing if the host machine has better tools. Thanks kpollock, I didn't think of that.
Both 2005 and 2008 Express editions have 4 gb limitation.
Have you thought about making a db copy on central server and dealing with it (just restore it into new db with other name)?

Looks like an SSIS job to me - which I think Express version of Management Studio doesn't have.
Or you could do it in C# calling Stored procs on the source database to extract the data if that's where your skills lie. (this is how I would do it as I think it's more widely comprehensible - but that's just my opinion).
If the database is live and new data comes in all the time perhaps you could set up the schema and reference data only then use replication to get the new data as it comes in (if you think that will get you a representative sample).
You will have to code up the sample extraction based upon an understanding of the schema - i.e. ensure you get a full set of linked records (e.g detail records for orders and all lookups e.g. customer, addresses, etc.).
