How to fetch a get a data for this scenario

[Kumar6]

Hello all,

I am facing problem in deriving the solution for below problem

Load 

dt_diff, sequence

5  , 1

45, 2

90, 3

180, 4

270, 5

I wanted a solution like this  below

dt_diff, sequence

5  , 0

45, 1

90, 2

180, 3

270, 4

Anything  less than dt_diff  45 should come under the sequence 0, then it should populate sequentially

hope my question is clear

any inputs appreciated

@Kumar6  just to understand what is the expected output from this :

dt_diff, sequence

5 , 1

45, 2

90, 3

4,4

180, 5

270, 6
