Question

I have two tables:

Table “one”:

ServiceID, ApplicationCode, Success
1, 1, 2
1, 3, 2
2, NULL, 3

Table “two”:

ServiceID, ApplicationCode, Failure
1, 1, 1
1, 2, 3
2, NULL, 4
3, NULL, 1

I want to receive that result table:

Columns:

ServiceID, ApplicationCode, Success, Failure
1, 1, 2, 1
1, 3, 2, NULL
2, NULL, 3, 4
1, 2, NULL, 3
3, NULL, NULL, 1

I’m using SQL Server 2008.

What query should I use ?

EDITED: I’m looking to join the two tables by ServiceID and ApplicationCode.

EDITED 2:
Code I’ve tried:

INSERT INTO #MidResult(ServiceID,ApplicationCode,SuccessCount,FailureCount)
SELECT case rtrim(ltrim(s.ServiceID)) WHEN NULL THEN f.ServiceID ELSE s.ServiceID END,s.ApplicationCode,s.SuccessCount,f.FailureCount
FROM #SuccessResult s
FULL JOIN #FailureResult f on f.ApplicationCode = s.ApplicationCode and s.ServiceID = f.ServiceID

You might be able to use the following:

select 
  coalesce(t1.serviceid, t2.serviceid) serviceid,
  coalesce(t1.ApplicationCode, t2.ApplicationCode) ApplicationCode,
  t1.Success,
  t2.failure
from table1 t1
full outer join table2 t2
  on t1.ServiceID = t2.ServiceID
  and isnull(t1.ApplicationCode, '') = isnull(t2.ApplicationCode, '')
order by serviceid, ApplicationCode

See SQL Fiddle with Demo.

The result is:

| SERVICEID | APPLICATIONCODE | SUCCESS | FAILURE |
---------------------------------------------------
|         1 |               1 |       2 |       1 |
|         1 |               2 |  (null) |       3 |
|         1 |               3 |       2 |  (null) |
|         2 |          (null) |       3 |       4 |
|         3 |          (null) |  (null) |       1 |
