Counting Parents and Children with Count Distinct

  • Article

The aggregate functions in SQL Server (min, max, sum, count, average, etc.) are great tools for reporting and business analysis. But sometimes, you need to tweak them just a little bit to get exactly the results you need. For example, if your manager came to you and asked for a report on how many sales have been made to your clients and how large they were, would you know how to get the data you need efficiently? Mark ran into something like this recently and here's the approach he took to solve the problem.

Question of the Day

Multiple Sequences

In SQL Server 2022, I run this code:

CREATE SEQUENCE myseqtest START WITH 1 INCREMENT BY 1;
GO
CREATE TABLE NewMonthSales
  (SaleID    INT
  , SecondID int
 , saleyear  INT
 , salemonth TINYINT
 , currSales NUMERIC(10, 2));
GO
INSERT dbo.NewMonthSales
  (SaleID, SecondID, saleyear, salemonth, currSales)
SELECT
  NEXT VALUE FOR myseqtest
, NEXT VALUE FOR myseqtest
, ms.saleyear
, ms.salemonth
, ms.currMonthSales
FROM dbo.MonthSales AS ms;
GO
SELECT * FROM dbo.NewMonthSales AS nms

Assume the dbo.MonthSales table exists. If I run this, what happens?
