如何在两列不同的表中的字符串中查找公用名？

Question

Im building a program in c# that consist in import two differents excel files into tables in data base, similar to this:

First table[Details]:

 Description                                Cost 
 Aeroport ticket by John                    200
 Emily Ticket to cinema                     200
 Aeroport ticket by Anna to the first class 500

Second Table[ClientInform]:

CostumerName Cost
John         200
Emily        200
Anna         500

Result table:

Description                               ClientName    Cost
Aeroport ticket by John                      John        200
Emily Ticket to cinema                       Emily       200
Aeroport ticket by Anna to the first class   Anna        500 

I have to display this on a gridview but if I have the right query I think I can do it in asp.net fairly easy.. I just don't know How to Seach in a string that can be random lenght, I was thinking in something similar to this:

select * from Details
full join ClientInform
on ClientInform.CostumerName= Details.Description
where Details.Description Like '%' +ClientInform.CostumerName+  '%'

something that Searche's similiar strings in both columns

ps: the code in sql is just a demonstration

Answer 1

Try something like this:

SELECT d.Description, c.CustomerName, c.Cost 
FROM Details d
INNER JOIN ClientInform c on d.Description Like '%' +c.CostumerName+  '%' AND c.COst = d.cost

Note : Like used on joining condition is sure kill the query performance.
