I don't quite understand the masterdb. The documentation online says it will store "user login" but what does that mean? When a user logs in, will it store info such as whether or not it was a successful login?

Understanding the masterDB -- would be it be able to tell me when user login attempts fail?

Delete and insert in transaction. Select returns not all records.
Hello,
Recently I have found some very interesting situation. It seems like a bug.
I have table:
CREATE TABLE [dbo].[_TestTable]([ID] [uniqueidentifier] NOT NULL,
[DataID] [uniqueidentifier] NOT NULL,
[Value1] [varchar](50) NOT NULL,
[Value2] [varchar](50) NOT NULL,
CONSTRAINT [PK__TestTable] PRIMARY KEY CLUSTERED
(
[ID] ASC
) ON [PRIMARY]
) ON [PRIMARY]
And .NET code witch do the following:
var cn = new SqlConnection();cn.ConnectionString = "Server=myserver;Database=mydatabase;User Id=myuser;Password=mypass";
cn.Open();
while (true)
{
var dataId = new Guid("53767E35-57B1-4729-9363-D14C2BC5D9AE");
using (var tr = cn.BeginTransaction())
{
var cmd = new SqlCommand($"delete from _TestTable WHERE DataID = '{dataId}'", cn, tr);
cmd.ExecuteNonQuery();
cmd.Dispose();
for (var i = 0; i < 10; i++)
{
var sqlQuery = $"insert into _TestTable(ID, DataID, Value1, Value2) values(newid(), '{dataId}', 'Some value 1 - {i}', 'Some value 2 - {i}')";
cmd = new SqlCommand(sqlQuery, cn, tr);
cmd.ExecuteNonQuery();
cmd.Dispose();
}
tr.Commit();
}
}
Then I open SSMS and execute the simple query
select * from _TestTable
In most cases I get 10 records. But sometimes I get 9, 8 or 7 records.

Giving dynamic sheet name while importing data from Excel in OPENROWSET query
I want to import data from Excel to table in SQL server. Sheets in Excel file can have any name. I want to get data from first sheet of the excel file.

MSDTC Failure - Enlist operation failed: 0x8004d01c(XACT_E_CONNECTION_DOWN).
Hi,
We had to recycle MSDTC for some other reason and noticed that all transactions started failing with the below error.
Enlist operation failed: 0x8004d01c(XACT_E_CONNECTION_DOWN). SQL Server could not register with Microsoft Distributed Transaction Coordinator (MS DTC) as a resource manager for this transaction. The transaction may have been stopped by the client or the resource manager.
All these transactions were going through fine until we recycled the dtc service. We noticed in some forums that the only solution is to restart sql server service.
Curious to know -
- What is the sql server registration process with MSDTC and what could cause this to fail?
- Any other resolution other restarting the services ?
- Any proactive measures to avoid this failure?

Uncommittable transaction when testing connectivity to (offline) linked server
Issue: when testing connectivity to an offline linked server wrapped inside a transaction, my transaction becomes uncommittable. However, I still need to execute the remaining code in the stored procedure. I am using sys.sp_testlinkedserver for testing connectivity. How to get around this issue?
Background:
I have two servers: ServerA and ServerB. Both are running SQL Server 2016. On ServerA I have a production database, and on ServerB I have a Historian database.
ServerA has a Linked Server object HISTORIAN which points to ServerB (using SQL User authentication) and has the default server options, except Collation Compatible which is set to True. Provider: SQL Server Native Client 11.0.
On ServerA a stored procedure sp_A1 is executed which starts a production order. This stored procedure calls another stored procedure sp_A2 that queries the Linked Server via the four-part name syntax, which queries certain Historian data and stores this on the production database with the started order.
Goal: if the Historian is not accessible (wrong user, server offline, MSSQLSERVER service not running) I still want to start the production order (we just don't store the Historian values in the production database).
Constraints: sp_A1 is always wrapped in a transaction, because of the way the user application connects to SQL Server on ServerA. I cannot change this, but I can change the stored procedures itself and SQL Server configuration. I cannot separate the calls to sp_A1 and sp_A2, meaning all the work that needs to be done needs to be initiated by a single stored procedure.
Example:
As a simple example I have created the excerpt below. Referring to the background discussed above, everything inside the BEGIN/COMMIT TRANSACTION would be sp_A1. And everything between the first and last SELECT statement would be sp_A2.
BEGIN TRANSACTION
SELECT'execute some code...'
DECLARE@return_codeINT
DECLARE@sSQLNVARCHAR(MAX)
--Use try and catch to test whether the Historian is accessible through linked server
BEGINTRY
PRINT('Testing
connection with the linked server.')
-- Tests the connection to a linked server. If the test is unsuccessful the procedure raises an exception
with the reason of the failure.
EXECsys.sp_testlinkedserverHISTORIAN
ENDTRY
BEGINCATCH
PRINT('Error
with accessing Historian, error_code = -5')
SELECT@return_code=-5;
ENDCATCH
SELECT@return_code
IF@return_code<>-5
BEGIN
SET@sSQL='SELECT
value1,value2 FROM HISTORIAN.Runtime.dbo.History WHERE order_id = ''12345678'''
EXECSP_EXECUTESQL@sSQL
END
SELECTXACT_STATE()
SELECT'execute
some more code...'
COMMIT TRANSACTION
Note that dynamic SQL is used to prevent syntax checking for the Linked Server on creation of the stored procedure (in cases where the linked server object has not yet been created, or when ServerB is not yet installed).
What I find is that when I execute this code without BEGIN/COMMIT TRANSACTION (and my Linked Server is unreachable), no error is thrown. But, when including the BEGIN/COMMIT TRANSACTION statements, the transaction becomes uncommittable. From what I understand is that this means SAVEPOINTS do not help here. The issue is that I have no way around the BEGIN/COMMIT TRANSACTION statements (see Constraints).
Is there a way around this? Or an alternative method to access the database on ServerB from a stored procedure on ServerA?
Thanks for your help and thoughts.

How to set up “log on” to the SQL Server running on my computer.
Because of the corruption of the personal account I have been using, I can no longer access to my SQL Server using “Window Authentication.” Therefore, I should like to set up a new “log on” as a Microsoft administrator using SQL Server Configuration Manager. As I display the menu of the running Server, I see the “Local System” checked. I also see the “This Account” unchecked with the login name box and the password box. How can I set up the new “Window Authentication” from the Microsoft administrator account? In case this is not possible, how can I set up “SQL Server Authentication” with this menu? Please instruct me. Thank you.

What I am trying to do is now use the authentication from the Azure AD to control access to rows in a table.
Does anyone have any documentation to get me to this point? I'm not sure how I link the Authentication token given to the API to access the SQL Server.
