My name is Lokesh Sharma, I have 5 years of experience working with SQL and am really interested in exploring more and more about this fascinating language. My aim here is to share some of the challenges that I faced while working with SQL and also to get feedback whether the approach I followed is an optimal one or not.
  • Interests: Writing and troubleshooting SQL Queries obviously :-). Other than that a fitness freak

Question of the Day

BIT_COUNT II

In SQL Server 2025, I have a table (dbo.UserPermission) that contains this data: 

UserID  UserPermissions
15
23
37
4       NULL
What is returned when I run this code: 
select bit_count(UserPermissions) as PermissionCount
from dbo.UserPermission
where UserID = 4;
