You didn't provided solution, that is just an article of capabilities.
I don't have to provide a solution. I'm not at work, this 'advice' is being given in my own spare time. I could be doing something productive, like the dishes, but I had chosen to answer this question. Might benefit someone, and I'm sure the dishes do not mind waiting

You already have - it's called the documentation[^]. Right on the first lines, it states short and precise;
There are two possible modes: Windows Authentication mode and mixed mode.

By the way, I don't use MySQL nor Oracle.
They were provided as alternative solutions to your problem.
I'm not going to provide any further pointers, as doing the dishes seems like a more important task suddenly.
Select EventID,(select count(*) from <myeventtable> E2 where E1.EventID = E2.EventID) As Count_of_A, (select count(*) from <myeventtable> E3 where E1.EventID = E3.EventID) As Count_of_B,
from <myeventtable> E1
I haven't tried this, however my first try would look like this:
SELECT DISTINCT UserID, StateCount_of_A, StateCount_of_B FROM tablename AS T1
LEFT JOIN (SELECT UserID, COUNT(*) AS StateCount_of_A FROM tablename AS TA WHERE State='A') ON TA.UserID = T1.UserID
LEFT JOIN (SELECT UserID, COUNT(*) AS StateCount_of_B FROM tablename AS TB WHERE State='B') ON TB.UserID = T1.UserID
ORDER BY UserID
(Actually I would try a subset of it with a single state first, then expand for the exact requirements).
The fundamental trick is to use the same table more than once, and give each "instance" a different name using the AS keyword.
And then one might have to throw in a couple of COALESCE functions to replace null counts by zeroes.
,CASE WHEN [State]='A' THEN 1 ELSE 0 END StateA
,CASE WHEN [State]='B' THEN 1 ELSE 0 END StateB
GROUP BY UserID
No, my 'base' or don't know how to call it server works fine and I am connecting to it as usual via 'Microsoft SQL Server Management Studio'. But when I enter to 'Microsoft SQL Server Management Studio' and try to register new server i.e. from the menu I choose from menu 'Register...' then appears the form 'New Server Registration' I cannot save this new server but cannot start it.
Testing the registered server failed. Verify the server name, login credntials, and database, and then click Test again.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40- Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
Yes I am using Windows authentication (in fact I can login via 'sa' also).
