Database Version Control

By placing under source control everything we need to describe any version of a database, we make it much easier to achieve consistent database builds and releases, to find out who made which changes and why, and to access all database support materials. Matthew Skelton explains how to make sure your version control system fully supports all phases of the database lifecycle, from governance, development, delivery and through to operations.

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;
