Compare subsets

Hello,
Does anybody know how to compare the subsets of two columns on different
tables? We have a column A in Table A that we want to compare any 10
characters to column B in Table B. Does anybody know the code to do this?
ThanksYou can join tables using the LIKE comparison operator, but it will result
in a table scan.
select
TableA.*
from TableA
join TableB on TableB.B like '%' + TableA.A + '%'
