No it will not cause any issue to SQL server database.Backup request reads data from disk using separate thread you just killed the thread.

SQL Server Database backup

Hi Team ,
I have SQL Cluster 2012 server running with Couple of Critical data base instance . Each instance installed in different drive.
One of my application database is having mdf of size 1 Gb and ldf is 250 GB . Database is set to full recovery model.
Now I want to change recovery model to simple and want to shrink the los also. before than I want to take database backup.
I have 50 GB space left in drive .
i want to take full database backup on same drive .please let me know how much space i need on that drive to take full backup.
thanks
Ravi

There are two options for you here
1. Take transaction log backup and try shrinking the log file but you might have to take multiple transaction log backups to actually shrink the log file
2. If you are switching from full recovery to simple you dont need to take full backup reason is switching from full to simple breaks log chain so its better to have Transaction log backup and like Praveen suggested if you take transaction log backup with
compression it likely it would fit in free space. But you have to try.
3. This you have to do on your own risk: (If backup of log in point 2 fails) I dont think changing from full recovery to simple would cause any
data loss. So you can switch to simple shrink logs switch back to full and schedule frequent log backups
Reason why log grew so much because you did not took sufficient transaction log backups. So create maintenance plan which would take frequent log backups also if you dont want point in time recovery for this database let it be in simple recovery

SQL Server Database backup and restore issue

Hi
I am trying to take a backup of the database and using restore to create its copy on the same server
Basically I am following this approach
http://stackoverflow.com/questions/3912221/ms-sql-2008-create-a-copy-of-the-database-without-the-data
Using the restore command is giving me the following error
RESTORE DATABASE [TargetDB]
FROM DISK = N'D:\backup.bak' WITH FILE = 1,
MOVE N'OriginalDB' TO N'D:\sql data\TargetDB.mdf',
MOVE N'OriginalDB' TO N'C:\SQL Data\TargetDB_1.ldf',
NOUNLOAD, STATS = 33
Logical file "ORIGINALDB" is not part of database "TARGETDB" . Use RESTOREFILELIST only to list
plz suggest as I checked the syntax is fine too as per
https://technet.microsoft.com/en-us/library/ms190447%28v=sql.105%29.aspx
I am using SQL Server 2012

LogicalName cant be same for mdf and ldf. verify again with FILELISTONLY. Also you have put wrong logical name
MOVE N'OriginalDB' TO N'D:\sql data\TargetDB.mdf'
Please paste the output of
RESTORE FILELISTONLY FROM DISK = 'D:\backup.bak'

Full Database Backup in DB13 for MS SQL Server databases

Hello,
We have some SAP systems using the MS SQL Server database. I want to know if it is possible to setup the Full Database Backup option in transaction DB13 to store the files in a hard disk space.
I already did this type of configuration in SAP systems in Oracle databases and for this I used the init<SID>.sap where we can put all the configuration, for instance the disk path where we want to save the backup files! But for MS SQL Server databases, in DB13, I don´t know how to do that, when I add the "Full Database Backup" option in DB13, this show me some options but only for tape, but I don´t want to store the backup files in tapes, I want to store/save the files on the server disk itself or else to an external disk but I don´t see where I can set this way of storage!
This is what you see in DB13 (when using a MS SQL Server database) in "Full Database Backup" and as you see I only have options for TAPE not for a disk or other type of storage! How can I do that? (if that is possible):
Can you help me please?
Kind regards,
samid raif

Hello Raja
Sorry for the delay of my answer! Many thanks for that tip, it helps a lot and it solve the last error/problem that I reported here, in fact, the problem was we had named the device with two words containing a space. So we removed that space from the backup device (in SQL management studio) with one word only and the job runs successfully without any errors!
It works in Development and Quality systems but in our Production system (AM1) the Full backup option in DB13 stopped with the following error, in fact the error is on verification of backup, it means that the Full backup finished with success, but when it does the backup verification, the job in DB13 stops with an error, the following one:

How to create a .mdf SQL Server database from a Data-Tier Application file that has data?

This is a noob question, though I do use SQL Server databases all the time with Entity Framework when I code in C# using Visual Studio 2013. The development environment is found below at [A]. I am trying to make a clone of a SQL Server 2008 R2
database (.mdf) that exists online. I can read, connect and work with this database in Visual Studio 2013, but I wish to make a local copy of the database, as an .MDF file. Somewhere in my notes I have a way of creating a local copy from
an online database when using Visual Studio but I forgot how (it seems, reviewing my notes, that it deals with ADO.NET which is deprecated in Visual Studio 2013 these days, or so it seems). So I'm looking for another way. What I did was create
(or export) a "Data-Tier Application File" from the online SQL Server database, with data, and it seems to have worked in that this Data-Tier Application file exists on my hard drive and seems to have data in it ("SQL Server Replication Snapshot"
is the format it seems). It contains skeleton code to create a database, but when I tried to execute it with SQL Server 2014 Management Studio, I got a bunch of errors.
So my question is:
1) Can I somehow create a .MDF SQL Server Database from an Data-Tier Application file that has data? What tool do I use? I saw this link, http://social.technet.microsoft.com/wiki/contents/articles/2639.how-to-use-data-tier-application-import-and-export-with-a-windows-azure-sql-database.aspx
and it relates to Azure, but is there a tool for C#Visual Studio 2013, standalone?
2) If there's an easy way to create a .mdf SQL Server Database file from an online file, within SQL Server Management Studio? I don't think so, since it would require Administrator permissions on the online server, which I don't have. I have permission
to read, update, delete the online database file, but strangely not to download it (the service I use has a tool for backup, but not for download).
3) same question as 2), but for Visual Studio 2013? I don't think so, since I notice none of the templates even mentions ADO.NET anymore, but instead they go with Entity Framework. Using EF I can of course do anything I want with the online database
(CRUD), but it remains online. Maybe there's a switch to make a local copy? I guess I could write a short program to suck all the data out of the online database and put it into a new, duplicate database having the same tables, that I create on
my localhost, but my question here is if there's an easier way than this, maybe a tool or command I can run from inside Visual Studio?
Any advice on any of the above questions is appreciated.
Thank you,
Paul

Thanks but these links are too general to help.
"2. what do you mean by online file?" - I mean the SQL Server database file is on a remote web server that I rent from, but I am not the administrator of. I can access my database using SQL Server Authentication, but nothing more.
Paul
What do you mean by too general? It explains on how you can use data tier application to create and deploy databases
May be this will help you to understand better

SAP ECC6.0 cannot connect to SQL Server Database after recreating DB server

We had a disaster with our ECC 6.0 Development system a few days ago. The system is called “DEV”. The SQL Server database server got wiped out and we didn’t have a backup. Luckily, we did have a backup of the database. Our system engineers rebuilt the server and our DBA reinstalled SQL Server and restored the database. The database came up fine, but when we try to start SAP, it fails. “R3trans –d” also fails. The database is SQL Server 2008R2 10.50.2769. The OS is Windows Server 2008R2.
We verified that the “devadm” and “SAPServiceDEV” accounts have permissions on the on the server. We set the following Environment Variables for the devadm account on the database server:
DBMS_TYPE = mss
MSSQL_DBNAME = DEV
MSSQL_SCHEMA = dev
MSSQL_SERVER = <database server name>
SAPLOCALHOST = <database server name>
SAPSYSTEMNAME = DEV
We also set the following Registry Key:
HKEY_LOCAL_MACHINE/Software/SAP/DEV
Type:     REG_SZ
Value:   AdmUser
String:   <database server name>\devadm
We didn’t install any kind of SAP software on the database server.
Is there any kind of SAP components we need to install on the database server? Do we need to run the SAP installer on the database server to get everything setup correctly? I looked at another one of our SQL Server database servers and it has SAP Management Console installed and there is a C:\Program Files\SAP\hostcntl folder. I don't know what that is or it has anything to do with SAP being able to connect to the database.
Here is the error message in the R3trans log file:

RickTextbox - getting and saving the text to and from SQL server database

I have no trouble saving the data to an SQL Server database. Here is a sample of what is saved.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}
\viewkind4\uc1\pard\f0\fs17 testing the\par
rich\par
text box\par
when I retrieve the text from the database, I end up with exactly what is shown above. I am retrieving the text with a SqlDataReader. here is the code that I am using;
while (sqlDataReader.Read())
string special_Instructions = ""; //first I was using this line but both lines have the same result // special_Instructions = sqlDataReader["Special_Instructions"].ToString();
special_Instructions = sqlDataReader.GetString(5);
special_InstructionsRichTextBox.Rtf = special_Instructions;
any guidance or help will be greatly appreciated.

Michael,
Lets begin with, 'Thanks for your guidance'. With your last run of questions, I was able to figure it out.
Here is what I learned, (by the way, this is in Winforms):
When I checked the properties of the RichTextBox control, I saw and then remembered that the control was bound to the form. First thing I did was comment out the code I was using (above) to fill the control and tested the program. I actually
received the same issue with the contents of the control as before.
I then dropped a new RichTextBox control from the tool box to my form and positioned it next to the original control. I un commented the above code and used it to fill the new
richTextBox1.Rtf and ran the program. The original control that was bound to the form still gave the incorrect result but the new control worked perfectly.
I hope this helps others and Thanks again for your guidance. If there is anything else you think could be added to this reply please let me know.

Move SQL Server database for App Controller

I need to migrate our App Controller server to another SQL Server.
I have copied the relevant SQL Server database. How can I reconfigure App Controller to use this new database?

Hi evilclive1,
To minimize the risk of data loss, I recommend the following steps:
Export the AES encryption key
from your existing App Controller installation
Make sure you have a backup of the App Controller database
On a spare VM, install a new instance of App Controller and connect to the new SQL server (you'll need the AES key from step 1).
Verify that the new instance of App Controller works correctly with the new SQL server (this will verify that you have a good copy of the App Controller database on the new SQL server)
Uninstall the original App Controller
On the original App Controller server, reinstall and point to the new database (you'll need the AES key from step 1)
Verify that this instance of App Controller works correctly with the new SQL server
There isn't a supported way to just change the database used by an existing install.
Kind Regards,
Richard

Can Oracle view refer a table in Sql Server Database

Can a view created in Oracle database refer a table created in SQL Server database. If yes, how do we do it. Code will be very help full.
Again, if yes does it require any special software and what would be price of that software.
Thanks for your response in advance.
Venkat Sathiamurthy

You would need to configure Oracle Heterogeneous Connectivity to create a database link to the SQL Server system. This can either be done via the Oracle Transparent Gateway for Microsoft SQL Server, which retails for $15,000 per server at http://store.oracle.com or by configuring Oracle Generic Connectivity and using ODBC to go after the SQL Server data. Depending on the operating system you run Oracle on, there may be a free (or cheap) ODBC driver for SQL Server that could be used.

How can I get an accurate count of computers (workstations) logged in to my SQL Server database?

We license our software by number of workstations.
I have a query that I have used for years to get an accurate count of the workstations logged in to my SQL Server database. For simplicity, all users use the same login name/password. This is built in to the script that attaches to the DB. They
have access only to that DB with the exception of
USE [Master] GRANT VIEW SERVER STATE to MyUser
The query that has been working is below:
Basically this relies on the mac address (Master.dbo.sysprocesses.net_addre
SELECT COUNT(Users) AS UserCount FROM (SELECT COUNT(Master.dbo.sysprocesses.hostname) AS Users FROM Master.dbo.sysprocesses LEFT OUTER JOIN Master.dbo.sysdatabases ON Master.dbo.sysdatabases.dbid = Master.dbo.sysprocesses.dbid WHERE (Master.dbo.sysdatabases.name = 'MyDatabase') GROUP BY Master.dbo.sysprocesses.net_address) AS UserCount_1
ss), since both Workstation names and ip addresses can be duplicated.
Recently this has stopped working at a number of customers. Suddenly individual workstations are showing multiple net addresses for the same workstation causing a substantial overcount of users. This may be related to SQL Server 2012 - not sure.
What I need is a very reliable way to get a count of workstations logged in to my database.
If anyone can tell me why I am suddenly getting multiple net_addresses for each workstation and how to prevent that that would be one possible solution.
Otherwise if anyone can give me a rock solid way to get a workstation count other than the above that would be great. Our largest customer is 50 users by the way.
Thanks in advance for any help.
Kim

I think your count is getting skewed because of duplicate rows in sysprocesses because of parallelism. Add DISTINCT to your query:
SELECT COUNT(Users) AS UserCount
FROM
( SELECT COUNT(DISTINCT Master.dbo.sysprocesses.hostname) AS Users
FROM Master.dbo.sysprocesses LEFT OUTER JOIN Master.dbo.sysdatabases
ON Master.dbo.sysdatabases.dbid = Master.dbo.sysprocesses.dbid
WHERE (Master.dbo.sysdatabases.name = 'MyDatabase'
GROUP BY Master.dbo.sysprocesses.net_address) AS UserCount_1

Is it possible to have different authentication mode for SQL Server Database Engine and corresponding SQL Server instance?

Hi,
I have installed the x64 SQL Server 2008 R2 Express with default settings and run MBSA 2.3 (using default settings too). It shows three SQL Server instances: MSSQL10_50.SQLEXPRESS, SQLEXPRESS and SQLEXPRESS (32-bit). For the first, authentication
mode is Windows, for the rest two - mixed. Here https://social.msdn.microsoft.com/Forums/sqlserver/en-US/03e470dc-874d-476d-849b-c805acf5b24d/sql-mbsa-question-on-folder-permission?forum=sqlsecurity question
about such multiple instances was asked and the answer is that "MSSQL10.TEST_DB
is the instance ID for the SQL Server Database Engine of the instance, TEST_DB", so in my case, it seems that MSSQL10_50.SQLEXPRESS is the instance ID for SQL Server Database Engine of the SQLEXPRESS instance.
I have two questions:
1) How can it be that SQL Server DB Engine instance has different authentication mode than corresponding SQL Server Instance?
2) Why 32-bit instance reported although I installed only 64-bit version?
Also, this https://social.technet.microsoft.com/Forums/security/en-US/6b12c019-eaf0-402c-ab40-51d31dce968f/mbsa-23-reporting-sql-32bt-instance-is-running-in-mixed-mode-when-it-is-set-to-integrated?forum=MBSA question seems to be related to this
issue, but there is no answer :(.
Upd: Tried on clean Windows 8 installation and Windows 7 with the same result.

Because I DO NOT want the three people who will be having access to the production SQL Server to also have access to the primary host ProductionA. Since I have to allow them to RDC into the box to manage the SQL Server, I figure why not create
a separate VM for each one of them and they can RDC into those instead.
Does this make any sense?
Any tips are greatly appreciated. The main reason for doing this is because the three people who will be accessing the box, I need to isolate each one of them and at the same time keep them off of the primary ProductionA.
Thanks for your help.
M
Hello M,
Since you dont want the 3 guys to have access to Production machine A.You can install SQL Server client .By client i mean SQL server management studio(SSMS) on there local desktop and then create login for them in SQL Server.Open port on which your SQL server
is running for three of the machines so that they can connct.Now with SSMS installed on each machine each can connect to SQL server from there own machine.
I would also like you to be cautious with giving Sysadmin privilege to all three of them ,first please note down what task they would do and then decide what rights to be provided.
Your option will also work but you need to create 3 VM for that .Which is more tedious task.
Hope this helps

Best practise for creating an application that connects to a SQL Server database

I am fairly new to vb.net and have read a few books and followed a few tutorials on youtube, what I would like to know is, are there any disadvantages
to the way I have connected to a SQL database using the SQLControl.vb. A lot of the vb books include data adapter and dataset within the form, I'm not sure if I'm following best practice by have the connection details outside of the form.
My other question is, I have created two connections in the SQLControl and call these connections within the same form using the same data adapter
and dataset. It all works fine but I just wanted to know of any potential issues?
Public SQLCon As New SqlConnection With {.ConnectionString
= "Data Source=;Initial Catalog=;Integrated Security=True"}
'connection 2
    Public SQLCon1 As New SqlConnection With {.ConnectionString
= "Data Source;Initial Catalog=;Integrated Security=True"}
Thanks

My other question is, I have created two connections in the SQLControl and call these connections within the same form using the same data adapter and dataset. It all works fine but
I just wanted to know of any potential issues
1) You are not using Sepration of concerns for a solution that is doing data access, like using a DAL.
http://en.wikipedia.org/wiki/Separation_of_concerns
2) You are directly issuing SQL commands at the UI, leading to sql injection attacks.
3) You are not using a UI design pattern, which leads you to tightly couple database activity to the UI.
http://www.codeproject.com/Articles/228214/Understanding-Basics-of-UI-Design-Pattern-MVC-MVP
@System243trd, parameters are important to prevent SQL injection attacks (people will insert SQL commands into the database if you do not perform basic checking of what you are passing to the database). If you write a stored procedure try to make
the variables the correct SQL server data type to avoid problems later of people trying to call it directly.  Darnold924 is right, I see no code to prevent against SQL injection attacks. In addition, during development in some instances LocalSQLDB
database system is used and during deployment you usually need to use the production SQL server database. Moreover, Linq-to-SQL is used on Windows Phone 8.1 and it is required for phone development later and so I highly recommend learning
it if you plan on developing windows phone applications.
@System243trd, If you want the code for the windows phone app I think it uses the MVVM model or that might be for universal apps or regular windows phone apps. I have been using the windows phone Silverlight pivot or panorama template (it might
be pieces of both). I've already submitted to the windows phone marketplace and it had to go through certification first. I plan on later making an article on it but I need to first fix one or two simple problems I have with it. Here's a link to
the source code if you later want to look at the source code (in vb.net):
