How to achieve this

[techvarun]

Hi Experts,

I have a table like below

Level	Account
10	A123
11	A245
12	123
12	133
12	143
12	153
12	163
12	173
12	183
12	193
11	A456
12	456
11	A466
12	476
8	A567
9	A678
10	A124

If I filter the by a where clause A123 it has to check the Level 10 and I need all the numerical values between Level 10 or less than 10 as the result.

123
133
143
153
163
173
183
193
456
466
476

If I select A245 The result would be

123
133
143
153
163
173
183
193
