Question

I have a table like this:

TransId.   LayerNo.  AccountId.   
100.       1.        2.        
100.       2.        3.        
120.       1.        5.        
120.       2.        6.    
120.       3.        12.     
70.        1.        2.   

I want to find transId(s) where:
(LayerNo = 1 and (accountId = 2 or 5))
and
(LayerNo = 2 and (accountId = 3 or 6))

And result set would be row no 1,2,3,4.
How could I write query to get the result?
My database is SQL server 2008 r2
Thanks in advance

SELECT TransId
FROM   your_table
WHERE  ( layerno = 1
         AND accountid IN ( 2, 5 ) )
INTERSECT
SELECT TransId
FROM   your_table
WHERE  ( layerno = 2
         AND accountid IN ( 3, 6 ) )
