I restore the backup to a test system(so yes a duplicate database) then I test a series of .Net apps on the restored data as a sort of sniff test.
SQL Server is 'generally' good at telling you if a backup restored with corruption - you could run a select query on the major tables as a sniff test, just to ensure that what comes back looks ok.
As a DBA you want to make sure that when the SHTF you can get the systems back to working within an agreed SLA(which is another point - make sure that you have an agreed SLA on how long a restore of a broken system will take and double the time you think it will take you, I can't stress how important this is because when things go wrong people behave irrationally and you need to be able to hold up that piece of paper to give yourself some space, in order to get on with fixing the systems).
A few useful sites worth reading.
Backups[^]
Validating a backup[^](if you are not subscribed it is well worth joining this site)
Database integrity[^]
I would strongly recommend an image backup every month with daily incremental image backups - disk space is cheap and rebuilding systems is expensive.
Another tip - if you are not running this all on a virtual machine, ensure that the SQL Server install is on a different disk to the software accessing it(this will further ensure its integrity and speed up access).

This should be easy enough to implement... I think.... (Well at least a duplicate database on the same server instance)

Good point - the guy is a mate, but he should know what is a reasonable recovery time...

I will suggest that he implements this (I think he brings in a consultant to help out with servers etc)

Not entirely sure what you mean here? The app is a standalone windows forms app, installed on the workstations, so I guess that should be fine.
Thanks for the links - will have a look shortly

Even more important to have an agreed SLA as it is good to be clear on where the boundaries of being a mate and being an employer lie

I take it there there is one central instance of an SQL Server rather than an instance on each workstation.
If there is one central instance then try to get it off the OS drive(probably the C: drive) so that disk access is not competing between OS calls and SQL Server calls - does that make sense?

Yes - one server instance on the server. Any yes I see what you mean. It makes sense, and I do remember reading something like that, but when I installed, I seemed to have missed where I could specify a different install location, so it installed on the C: drive (default).. At the moment there are way more serious performance hits in the app itself (populating too many datagrid rows at a time etc) - Only realized this when I got a copy of their data a year after the initial installation... I'd been testing with a bare bones DB on my machine - so yeah what those poor users have been going though - aw shame!

Hi,
I have been asked solution for this.
I have Vendors where i get different excel file (diffrenct structure) from different vendor.
Vendor1 excel file
------------------
Name, Address, Age
Vendor2 Excel file
------------------
CandidateName, PhysicalAddress, Age
what ever Header Names but meaning is same.
Order of Headers are may vary different...
but i need to map in Sqlserver with correct mapping means i have table like (CandidateName,CandidateAddress,Age).... Here i need to store correct data columns which are mapped from above two excels.
Is there any solution in Sqlserver or ssis or .NET solution to identify Generic Columns of excel(xls) and map to Sqlserver Table correctly.
Thanks,
Ravikiran

Unless you have "something" that you can use to identify the type of data in that column, there's nothing to map. If both names and order change, then the computer will no longer be able to distinguish between a first-name (string) and a last-name (string).
I'd suggest to use the table-headers to "propose" a mapping for that particular vendor, based on the current file and your best guess (based on a "contains"-call on the header to try and identify it) and to save/use that.

Oh the joys of dealing with people who use Excel as a data source  .
The only reliable way will be to maintain a mapping table for each source, Load your data into staging tables (I use bulkcopy, creating a new table based on the source), then test the structure against your map, process or spit the dummy based on the structure check.

The only solution I know of is to load the data excel data into raw tables - stage this data then qc it with queries etc.
Once you are happy with the integrity of the data you can then load it into your database.
Basically this amounts to a datawarehousing system - you will need human input between the staging and load to warehouse. This is where the qc comes into effect.
All data that comes from a client needs to be qc'd with a human eye as invariably there will be data that breaks your business logic.
Don't trust client data, especially if it is in Excel format!
If any data is incorrect then the standard procedure is to ask the client to resend the corrected data - it should never be the software or receivers job to 'correct' raw data, since as soon as you 'correct ' the data you then become responsible for its contents.

Create an "adaptor" (concept rather than a specific type of implementation) specific to each vendor. I suggest STRONGLY that you use extensive error checking on such an adaptor because that is the only way you will detect when they change the format.
The vendor files are delivered to a vendor specific folder and that is used as a key to determine which adaptor is used to process them.
The adaptor could be written in either SQL or C#. I would choose C# because it provides more flexibility for this sort of operation. Note that a C# solution need not go directly to the database. In can just output a file, with a fixed known format, which is then used as an import file to SQL Server.
The adaptors should also have error reporting, logging is good, to report on failed conversion attempts, as well as when successful ones ran.

How can I backup my db through the terminal, what is the command?

Hi All,
I am trying to run this query on my database and I am getting an error Incorrect syntax near the keyword 'JOIN'.
USE IVRCallCenterTest
Go
SELECT *
FROM dbo.OutputPromptItem WHERE SegmentId=7198
JOIN dbo.OutputPrompt
ON dbo.OutputPromptItem.PromptId=dbo.OutputPrompt.PromptID
Go
what is wrong with my code ?
Thanks in advance
|

Your Where clause needs to come after From.
USE IVRCallCenterTest
Go
SELECT *
FROM dbo.OutputPromptItem JOIN
dbo.OutputPrompt ON OutputPromptItem.PromptId = OutputPrompt.PromptID
WHERE SegmentId = 7198
Go
|
|
|
|
|
You should use Where Clause at End of Statement
Like
SELECT *
FROM dbo.OutputPromptItem
JOIN dbo.OutputPrompt
ON dbo.OutputPromptItem.PromptId=dbo.OutputPrompt.Promp WHERE SegmentId=7198

I went through security and added. Checked the owners and added sa and admin account. I just can't seem to figure out what I have missed! DBs detached, copied, and moved from test server to actual network server seems to have not included a "setting" or "configuration". Any ideas? Using Windows Authentication.
The odd is that I can connect and see the Master, but not the attached databases that were added. And yes, they were attached and brought online. The fact that I can see the master tells me that I have the router rules set correctly. I am open to any suggestions. Throw it at me. I have to have missed something obvious.
FIXED!
The problem exists in policy, whether group or user I did not explore further. Installed SQL Server as a local machine with local admin. I completely took the server offline for the initial setup. Reconnected using the suggested username/password as well.
Not a problem at all.

What UI are you using to manage the databases?

The following are the only possibilities.
- The database has not been attached,
- You are not connecting to the database server that you think you are.
- The user permissions are wrong.
PrissySC wrote: <layer> The fact that I can see the master tells me that I have the router rules set correctly
If you couldn't route to the database server then you couldn't connect nor log in. It has nothing to do with whether you can see databases.

See, that is where I am puzzled!
I specifically went in and gave public access as well as set the Owner to the account.
So then, thinking aloud, I should look at the owner.
Should I look at builtin\users or default admin account?
I already set the NT. From there, I assume, properties, user mapping. Checked the DB in question and provided membership to owner and public.
I will check the server roles and grant status for the user too. Hmmm .... at least you agree with me!
Thanks, and if you think of something else, I will check back and keep this thread updated.

If you have restored/attached the database from a different server you may need to drop and reapply the user permissions, while the name is the same the id values are different.
While I use windows authentication in SSMS I have all my apps have a SQL identity and uses that, so a connection string ALWAYS has a userid and password, never integrated.

I would have agreed, but I created a new database on the SQL server. I went to a client machine to connect, and once again, the new database does not show in the list. I get the SQL list with master and such.
Truly, this is really bothersome. It is almost as if there is a "scope" problem. Could the GPO affect this? It is an Admin of the domain, but what was given to me was that this admin account has full access. I would think to differ only because ... SQL installs with a local machine admin yes?
Creator/Owner does have special permissions by default on 2008 ... would any portion of this effect the DATA folder where the database has been relocated for attachment?
Lastly, I will try using nonintegrated methods and consider troubleshooting ID values as well per Mycroft Holmes' post.

I have set up a second instance of SSRS 2005 on a Microsoft 2003 server using the custom security extension sample. I have the report server login working with the custom security extension, but cannot seem to get the report manager working with this.
The error I am getting is "The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version."
Now what I thought was that the logon form would display, the admin would login and then be able to add roles, etc. Is this wrong? If so, how is it supposed to work and how to I configure it to work that way?
Below is how I have my report manager config's configured.
ReportManager folder - RSMGRPOLICY.CONFIG
<CodeGroup
class="UnionCodeGroup"
version="1"
PermissionSetName="FullTrust">
<IMembershipCondition
class="UrlMembershipCondition"
version="1"
Url="$CodeGen$/*"
/>
</CodeGroup>
ReportManager folder - RSWEBAPPLICATION.CONFIG
<UI>
<CustomAuthenticationUI>
<loginUrl>/Pages/UILogon.aspx</loginUrl>
<UseSSL>False</UseSSL>
</CustomAuthenticationUI>
<ReportServerUrl>http:/servername/ReportsExternal</ReportServerUrl>
</UI>
ReportManager folder - WEB.CONFIG
<identity impersonate="false"/>

Dear friends,
For days now, I have been trying to restore a backup of the database (with command prompt) I had made with mysqldump. This is my line of code.
"C:\Program Files\MySQL\MySQL Server 5.5\mysql --user=root --password=mypassword --host= localhost --port= 3306 --database=dbname < C:/Backup/dbname.sql"
I get "The filename, directory name, or volume lable syntax is incorrect" error messsage. I have googled for this error to no avail as to do with mysql.
- My mysql server is up and running with no problem. (Even the mysqldump command works)
-Problem is the same even if I open the command prompt from C:\Program Files\MySQL\MySQL Server 5.5\mysql
-I have tried to remove "", did not help.
- I tried to change / with \ but no success.
For this one, I will really appreciate any help.

Get the MySQL GUI Tools and try with them. That's the easiest way.
My impression is that you do something wrong with spaces and quotation marks. What about
"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysql.exe" --user=root --password=mypassword --host=localhost --port=3306 --database=dbname < "C:\Backup\dbname.sql"
In case of the GUI tools, you need not worry about that.

Thank you. I got through it, and yes, the trick was to remove " before the first --user...

Hi all,I have a problem with back up command!
I use this code but it doesnt work:
string constr = @"DataSource=.\SQLEXPRESS;AttachDbFilename=C:\Users\EHSAN\Documents\Visual Studio 2010\Projects\hokm\hokm\App_Data\Database1.mdf;Integrated Security=True;User Instance=True;";
System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection ();
con.ConnectionString = constr;
con.Open();
System.Data.SqlClient.SqlCommand comm=newSystem.Data.SqlClient.SqlCommand();
comm.CommandText = @"backup database Database1 to disk ='c:\Users\EHSAN\Documents\Visual Studio 2010\Projects\hokm\hokm\DBbackup.bak' with init,stats=10";
comm.Connection = con;
comm.ExecuteNonQuery();
con.Close();
and when I run it, I get this error:
Database 'Database1' does not exist. Make sure that the name is entered correctly.
BACKUP DATABASE is terminating abnormally.
but I use the database1 and I connect it successfully!
what is the problem?
