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?
