Steve Hughes is the Director of Consulting at 3Cloud. In my current role, I manage the West and Central Data & AI consultant team at 3Cloud. I did a similar role at Pragmatic Works before our merger with 3Cloud. I focus on team development and company growth with this role. In my previous role as a Principal Consultant Lead at Pragmatic Works, I focused on designing solutions for customers on Microsoft technologies including SQL Server, Power Platform, and Azure.

Kristyna Hughes is the Team Lead for BI at GlobalTranz. I have played an instrumental role in moving our company from 3 different reporting platforms to hosting our reporting within Power BI. I provide advice on security structures within the platform, manage the gateways, create and implement design strategies, train, and build reports for both our internal operations committee and external customers. I will also be aiding in embedding Power BI within an unified TMS and ensuring various levels of security are maintained within the embedded reports.

Question of the Day

Using Outer Joins

I have this data in a SQL Server 2019 database:

Customer table
CustomerID CustomerName
1          Steve
2          Andy
3          Brian
4          Allen
5          Devin
6          Sally

OrderHeader table
OrderID CustomerID OrderDate
1       1          2024-02-01
2       1          2024-03-01
3       3          2024-04-01
4       4          2024-05-01
6       4          2024-05-01
7       3          2024-06-07
8       2          2024-04-07
I want a list of all customers and their order counts for a period of time, including zero orders. If I run this query, how many rows are returned?
SELECT 
  c.CustomerName, COUNT(oh.OrderID)
 FROM dbo.Customer AS c
LEFT JOIN dbo.OrderHeader AS oh ON oh.CustomerID = c.CustomerID
WHERE oh.Orderdate > '2024/04/01'
GROUP BY c.CustomerName
