How can i resolve a hostname in t-sql? a 2000 compatible method is preferred. Although something that works on 2005/2008 would also be helpful.
eg. If i have the hostname stackoverflow.com i want to return 69.59.196.211
Well, I suppose you could use xp_cmdshell to execute nslookup and parse the results. Seems like a really awkward thing for SQL Server to be doing, though.
exec master..xp_cmdshell 'nslookup intel.com'
.. then you'll probably want to stuff that in a temp table and walk through the results.
You could also, if you can get access to SQL Server 2005 or 2008, build a stored procedure or function in .NET and do a simple call to Dns.GetHostAddresses().
SQL Server may block access to procedure 'sys.xp_cmdshell' as part of the security configuration. As a system administrator you can enable the use of 'xp_cmdshell' as follows:
-- Allow advanced options.
EXEC sp_configure 'show advanced options', 1;
GO
-- Update the currently configured value for advanced options.
RECONFIGURE;
GO
-- Then, enable the feature.
EXEC sp_configure 'xp_cmdshell', 1;
GO
-- Update the currently configured value for this feature.
RECONFIGURE;
GO
-- Then you can go ahead and run ...
exec master..xp_cmdshell 'nslookup microsoft.com'
GO

Can you please help me to fix this query?
SELECT
FROM OPENROWSET('SQLNCLI',
'Server=.;Trusted_Connection=Yes;',
'SET FMTONLY OFF;EXEC master.sys.xp_readerrorlog')
I get this error:
Msg 11519, Level 16, State 1, Procedure sys.sp_describe_first_result_set, Line 1 [Batch Start Line 12]
The metadata could not be determined because statement 'EXEC master.sys.xp_readerrorlog' invokes an extended stored procedure.
I have enabled Ad-Hoc Distributed Queries as well by using below query but getting same error.
EXEC sp_configure 'show advanced options', 1;
RECONFIGURE;
EXEC sp_configure 'Ad Hoc Distributed Queries', 1;
RECONFIGURE;
GO
You cannot use OPENROWSET for an extended stored procedure. You could create a linked server
EXEC {Your Linked Server Name}.master.sys.xp_readerrorlog;
But you say you have 120 instances. (Quite why you don't have management software for so many, is another question...) So you are better off using Powershell to do this. For example
Get-SqlErrorLog
-Since LastMonth
-ServerInstance "your","Server","Instances","Here"
You would probably want other code to filter and group the results, but you haven't shown what you want.
For example you could do something like this
Get-Content "ServerInstances.txt"
| Get-SqlErrorLog -After "2022-09-16 10:00:00"
| Where Source -eq "Backup"
I need to change degree of parallelism, but when i run that i am getting error
Could not find stored procedure 'sp_configure'.
Here is my script for that
USE test;
GO
EXEC sp_configure 'show advanced options', 1;
GO
RECONFIGURE WITH OVERRIDE;
GO
EXEC sp_configure 'max degree of parallelism', 8;
GO
RECONFIGURE WITH OVERRIDE;
GO
It seems you are using Azure SQL Database where sp_configure is not available. Use ALTER DATABASE SCOPED CCONFIGURATION instead to configure MAXDOP.
I'm desperately trying to activate FileStream only with queries. By following the MSDN procedure everything is ok, but I would like to enable it without using SQL Server Configuration Manager or SQL Server Management Studio.
On several website I read that this query was enough to activate this feature (this query is done in the MSDN procedure but after some configuration in SQL Server Configuration Manager ) :
EXEC sp_configure 'filestream_access_level', 2;
GO
RECONFIGURE
GO
The message L option de configuration filestream access level est passée de 2 à 2. Pour installer, exécutez l'instruction RECONFIGURE." is gave but if I check the service's proprieties Filestream is steal disabled, even if I execute RECONFIGURE again. If I try to open a connection to a base featuring Filestream columns i get a message confirming Filestream is not enabled.
I also tried this query :
USE master
GO
EXEC sp_configure 'show advanced options'
GO
EXEC sp_configure filestream_access_level, 3
GO
EXEC sp_filestream_configure
#enable_level = 3
, #share_name = N'FS';
GO
RECONFIGURE WITH OVERRIDE
GO
Without succes, althougth the sp_filestream_configure seems to not exist.
This website tell the issue could be the default language of my server, but after change the default language to English nothing was better.

I hope someone will be able to help me. Thanks. Sorry for my bad english, I'm french ;)
You have to do both. One is enabling the feature in the configuration manager. The other is setting the access level.
Here's the MSDN guide to walk through:

You're only doing step 11, you need to do the first 10 steps as well.
I've got a problem whereby I need to read data from a .txt file into a variable in SQL Server. The read needs to be performed programmatically, as it's going to form part of a stored procedure, and it needs not to utilise the BULK method, as I don't have permissions to use the BULK method on the database in question. Is this possible?
Thanks in advance :)
Can you get them to allow Ad Hoc Distributed Queries? Then you can use OpenRowset or OpenDatasource.
SELECT *
FROM OPENROWSET('MSDASQL',
'Driver={Microsoft Text Driver (*.txt; *.csv)};DefaultDir=c:\users\graham\desktop;',
'SELECT * FROM [data.txt];'
Here's the recofiguring code, if you need it:
EXEC sp_configure 'show advanced options', 1;
RECONFIGURE;
EXEC sp_configure 'Ad Hoc Distributed Queries', 1;
RECONFIGURE;
go
This is a laborious technique, though -- you sure you can't use client code? Even, I dunno, VBA in Excel or something?

There is no other way to read the contents of a file without these permissions in SQL Server, or without setting up a link to the file. Otherwise, you have to do this through SSIS or using programming.
The solution is to get the permissions to solve your issue.
Opening a batch file using SQL Server procedure....
For this, I took the example of opening a notepad. And able to open it with the following code :
start "c:\windows\system32" notepad.exe
--- saved as : note.bat
I tried to open it with following procedure :
ALTER procedure [dbo].[executebat]
as
begin
EXEC master.dbo.xp_CMDShell 'D:\ducont\note.bat'
end
also I enabled the xp_cmdshell option with following code ::
-- To allow advanced options to be changed.
EXEC sp_configure 'show advanced options', 1
GO
-- To update the currently configured value for advanced options.
RECONFIGURE
GO
-- To enable the feature.
EXEC sp_configure 'xp_cmdshell', 1
GO
-- To update the currently configured value for this feature.
RECONFIGURE
GO
But when I try to execute the procedure, it showing continuously
" Query Executing..."
and no output !!
Guide me if I went wrong anywhere .
Simple answer. When you run xp_cmdshell it is creating a shell to do any work you ask it to. Your bat file is running inside that shell, and will open notepad, again inside the shell. You just won't be able to see it. Since it's expecting input (and can't get any) you are stuck with the " Query Executing..."
There really isn't a good way to do what you are asking for other than possibly using CLR. Unfortunately I don't know enough about it to say for certain one way or another. There may be an easier way in SQL 2012 or 2014 but I haven't seen it yet.
