I have 2 tables linked as

Table A
=======
Field1 - (FK to Table B)
Field2 - (Integer value)

Table B
=======
Field1 - Id (PK)
Field2 - Name(x,y,z)

I have these data in Table A
=============================
Field1 Field2
1 10
1 5
2 7
3 6

Table B Data
============
Field1 Field2
1 X
2 Y
3 Z

Now I need a query which will have aggregate SUM of Table A.Field2 for all id in TableB and aggregate SUM of Table A.Field2 for all id in TableB except id 2 as

SELECT SUM (Table A.Field2) for all id of Table B,
SUM (Table A.Field2) for all id of Table B except id 2

FROM Table A, TableB
WHERE .......

Is it possible to have it in single query? If so how can we do it? Please help me.

[code]SELECT
SUM (a.Field2) AS Toatl,
SUM (CASE WHEN b.Field1<> 2 THEN a.Field2 ELSE 0 END) AS Total2
FROM TableA a
JOIN TableB b
ON a.Field1=b.Field1
[/code]
