Question of the Day

The Range of Customers

I have this data in the OrderHeader table in a SQL Server 2025 database (ordered by CustomerID ASC):

orderid orderdate               customerid complete
3       2025-05-10 00:00:00.0002          1
21      2024-01-10 00:00:00.0003          1
15      2023-10-28 00:00:00.0004   1
13      2025-03-08 00:00:00.0006          1
11      2024-04-02 00:00:00.0007          1
If I run this query, how many rows are returned?
SELECT *
 from dbo.OrderHeader
 where customerid between 3 and '6'
