Check users in a security group in SQL Server

Question

In the Security/Users folder in my database, I have a bunch of security groups, include \"MyApplication Users\". I need to check if I am (or another user is) in this group,

Answer 1

The code that is provided on the Microsoft page here works for me, every time.

SELECT DP1.name AS DatabaseRoleName,   
   isnull (DP2.name, 'No members') AS DatabaseUserName   
 FROM sys.database_role_members AS DRM  
 RIGHT OUTER JOIN sys.database_principals AS DP1  
   ON DRM.role_principal_id = DP1.principal_id  
 LEFT OUTER JOIN sys.database_principals AS DP2  
   ON DRM.member_principal_id = DP2.principal_id  
WHERE DP1.type = 'R'
ORDER BY DP1.name;

Please let me know if this works for you!
