How to generate a Score table easily?

Question

I would like to ask how to generate a Score table easily. The Score table has fields ID, StartValue, EndValue and Score, see below.
The logic is if a field is between the StartValue and EndValue, a score is given.

The StartValue and the EndValue have six decimal places.
An interval between two adjacent numbers for the Score field is 0.5.
An interval between the StartValue and the EndValue is around 5.
The values of the EndValue field are from -500 to 500.

Score Table
ID StartValue EndValue Score
1 0.000001 5.000000 0.5
2 5.000001 10.000000 1
3 10.000001 15.000000 1.5
4 15.000001 20.000000 2
.....
100 455.000001 500.000000 50

101 -4.999999 0.000000 0
102 -9.999999 -5.000000 -0.5
103 -14.99999 -10.000000 -1
104 -19.99999 -15.000000 -1.5
105 -24.99999 -20.000000 -2
......
xxx -504.999999 -500.000000 -50

Thanks in advance!

Hi @Rainbow1517 ,

Welcome to Microsoft Q&A!

Please refer below:

create table Score   
(ID int,   
StartValue decimal(12,6),  
 EndValue  decimal(12,6),  
 Score decimal(5,1))  
 
 ;with cte as (  
 select row_number() over (order by (select null))  as n  
       from   master..spt_values    
          )  
 insert into Score  
 select n,0.000001+5*(n-1),5.000000*n,0.5*n from cte where n<=100  
 union all  
 select n,0.000001-5*(n-100),-5.000000*(n-101),-0.5*(n-101) from cte   
 where n>100 and n<=201  
  
select * from Score
