Question

I have this table :

TABLE Transaction
Trans_ID    Name    Value    Total_Item  
100          I1     0.33333333        3  
100          I2     0.33333333        3  
100          I5     0.33333333        3  
200          I2     0.5               2  
200          I5     0.5               2  
300          I2     0.5               2  
300          I3     0.5               2  
400          I1     0.33333333        3  
400          I2     0.33333333        3  
400          I4     0.33333333        3  
500          I1     0.5               2  
500          I3     0.5               2  
600          I2     0.5               2  
600          I3     0.5               2  
700          I1     0.5               2  
700          I3     0.5               2  
800          I1     0.25              4  
800          I2     0.25              4  
800          I3     0.25              4  
800          I5     0.25              4  
900          I1     0.33333333        3  
900          I2     0.33333333        3  
900          I3     0.33333333        3  
1000         I1     0.2               5  
1000         I2     0.2               5  
1000         I4     0.2               5 

I need to find what transaction containing some item.
EX: 2 item combination

I1 and I2 and keeping only related item value;

Trans_ID    Name    Value    Total_Item  
100          I1     0.33333333        3  
100          I2     0.33333333        3  
400          I1     0.33333333        3  
400          I2     0.33333333        3  
800          I1     0.25              4  
800          I2     0.25              4    
900          I1     0.33333333        3  
900          I2     0.33333333        3    
1000         I1     0.2               5  
1000         I2     0.2               5  

note that i only show transaction containing both item.

or perhaps 3 item combination
I1,I2 and I3

800          I1     0.25              4  
800          I2     0.25              4  
800          I3     0.25              4   
900          I1     0.33333333        3  
900          I2     0.33333333        3  
900          I3     0.33333333        3  

How do i code that in sql?
i’m working with msaccess)

Answer 1

These will work in Access:

SELECT * FROM Transaction t 
WHERE t.Trans_ID IN 
    (SELECT t1.Trans_ID
     FROM (SELECT *
           FROM Transaction 
           WHERE [Name]="I1")  AS t1 
     INNER JOIN 
          (SELECT *
           FROM Transaction 
           WHERE [Name]="I2")  AS t2 
     ON t1.Trans_ID = t2.Trans_ID)

AND t.Name IN ("I1","I2")


SELECT * FROM Transaction t 
WHERE t.Trans_ID IN 
    (SELECT t1.Trans_ID
     FROM ((SELECT *
           FROM Transaction 
           WHERE [Name]="I1")  AS t1 
     INNER JOIN 
          (SELECT *
           FROM Transaction 
           WHERE [Name]="I2")  AS t2 
     ON t1.Trans_ID = t2.Trans_ID)
     INNER JOIN 
          (SELECT *
           FROM Transaction 
           WHERE [Name]="I3")  AS t3 
     ON t1.Trans_ID = t3.Trans_ID )

AND t.Name IN ("I1","I2","I3")
