Scripts
A DateRange Table Valued function
The function is an inline table-valued function (or sometimes called a parameterised view) so it can be used just like a view or a table but needs parameters. It generates a single-column table of datetime2 with rows differing by any multiple of any of the dateparts that SQL Server provides.

Look up AD user properties using powershell
I realize that this is a bit of a lengthy script for something that you can use a one liner in the power shell:
Example:
Get-ADUser
But I needed to highlight certain properties of given user and take certain actions based on the values. And the result is this power shell script.

Question of the Day
The string_agg function
We create the following table and then insert some records in it:
create table t1 ( id int primary key, category char(1) not null, product varchar(50) ); insert into t1 values (1, 'A', 'Product 1'), (2, 'A', 'Product 2'), (3, 'A', 'Product 3'), (4, 'B', 'Product 4'), (5, 'B', 'Product 5');What happens if we execute the following query in both Sql Server and PostgreSQL?
select id,
category,
string_agg(product, ';')
over (partition by category order by id
rows between unbounded preceding and unbounded following) as stragg
from t1; See possible answers
