通过执行以下存储过程，您可以在以下位置获取/检查SQL Server身份验证: XP模式:

By executing the below stored procedure, you can get/check SQL server authentication in XP mode:

DECLARE @AuthenticationMode INT
EXEC master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE',
N'Software\Microsoft\MSSQLServer\MSSQLServer',
N'LoginMode', @AuthenticationMode OUTPUT

SELECT CASE @AuthenticationMode
WHEN 1 THEN 'Windows Authentication'

ELSE 'Unknown'
END as [Authentication Mode]
