Fredo

DerFredo aka Thomas holds a degree in Business Economics, but has been a data explorer and a developer at heart ever since the days of dBase and Turbo Pascal. He touched his first SQL Server at V6.5, used covering indexes before they became a feature and joined the PASS community in 2006.

Thomas has been developing in Navision/Dynamics/Business Central systems for quite some time (since 2001, one year before MS acquired Navision), got his hands on R in 2014 (the year before MS bought Revolution Analytics), on the Power Platform from 2020 and the Arduino world from 2024 on. He has worked for ISVs as well as end-user companies, as a developer, consultant, accidental data engineer and is an author for data-related articles as well as a speaker at data events across Europe.
  • Skills: SQL, R, BC, ERP, Arduino

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?
