Solution 1

Use SUBSTRING and CAST to extract the number part of your string and sort on that value.
SQL - Substring Function | 1Keydata[^]
CAST and CONVERT (Transact-SQL)[^]

Solution 3

Your query will be

SQL

select   Names  from myTable order by
CAST(RIGHT(Names,len(Names)-5) AS int)

Then your Result will be:

LD_B_1
LD_B_2
LD_B_10
LD_B_100
LD_B_101
LD_B_200

Happy Coding! :)
