What kind of check should I do? Substring helping

Question

Hi guys, I'm struggling to fin a solution to this problem: I'm building a package in SSIS that allow me to load, transform, check thousand of xls file. Everything is ok but now I ran into a logic issue ( and maybe I'm too tired to concentrating on properly).
The xls format has this format:
Sample 1
Title
dc_cost_201404_16-07-2014 180022
Row
dc_cost:201404:R000251178
dc_cost:201404:R000251178
dc_cost:201404:R000251178
Sample 2
Title
cl_exempt_chg_201405_16-07-2014 180022
Row
cl_exempt_chg:201405:R000250503
cl_exempt_chg:201405:R000250503
I'm trying to find a meaning. I was thinking something like Findstring([column], @file,1)....or something with the SubString..
any idea? Thanks

DECLARE @forumTable TABLE (col1 VARCHAR(20), col2 VARCHAR(20), col20 VARCHAR(20), col12 VARCHAR(20))
INSERT INTO @forumTable (col1, col2, col20, col12)
VALUES
('dc_cost:201404','dc_cost_201404','chj_charge_lmt', '201402'), --In this case match
('dc_cost:201404','dc_cost_201405','chj_charge_lmt', '201402'), --In this case no match
('xx_cost:201404','dc_cost_201404','chj_charge_lmt', '201402'), --In this case no match
('xx_cost:201404','xx_cost_201404','chj_charge_lmt', '201402') --In this case match
SELECT *, col20 + '_' + col12,
CASE WHEN LEFT(col1,2) = LEFT(col2,2) AND RIGHT(col1,6) = RIGHT(col2,6) THEN 'MATCH!'
ELSE 'NO MATCH!'
END,
CASE WHEN CHARINDEX(col20 + '_' + col12,'chj_charge_lmt_201402_16_07_2014 11000BB') > 0 THEN 'Title Match!'
ELSE 'No Title Match!'
END
FROM @forumTable
