Login trigger SQL SERVER

Good afternoon!

I need to create a logon trigger that blocks some login access via Management Studio.

I need to inform the list of logins that must have access to access SQL Server via Management Studio.

Can someone help me please?

Thank you very much

So here's a simple version that should do the trick:
CREATE TRIGGER logon_trigger_filter
ON ALL SERVER FOR LOGON AS
BEGIN
IF APP_NAME() LIKE 'Microsoft SQL Server Management Studio%' AND LOWER(SYSTEM_USER) IN ('testlogin')
	ROLLBACK
END

Open in new window

It wouldn't be too difficult to enhance this basic logic so the APP_NAME values and the SYSTEM_USER values can be read from a table that is maintained. I suppose you could also join SYSTEM_USER on the sys.server_role_members table to tie this to a server role based approach. Here's a quick & dirty query that will show all server roles to whom the SYSTEM_USER belongs.
SELECT * FROM [sys].[server_role_members]
INNER JOIN [sys].[server_principals] ON [principal_id] = [role_principal_id]
INNER JOIN [sys].[server_principals] [members] ON [members].[principal_id] = [member_principal_id]
WHERE
[members].[name] = SYSTEM_USER

Open in new window
