ADD Specific values in SQL Column determined by other Column - sql

Question

I have a Database that determines different values based on a label.
Where the label determines whether it's an exempted value or not.
For instance, 2 = non exempted and 3 = exempted. If I run a query my results look something like this
|Name |ExemptionStatus |Total Value|
|X |2 |100 |
|X |3 |200 |
My Query is
SELECT NAME, EXEMPTIONSTATUS
SUM(TOTAL_VALUE) AS 'TOTAL VALUE'
FROM ORDER_ACCOUNT JOIN ACCOUNT_INVOICE
WHERE ORDER_ACCOUNT.DATE BETWEEN 'M/D/YEAR' AND 'M/D/YEAR'
GROUP BY NAME, EXEMPTIONSTATUS
ORDER BY NAME ASC
How can I get my query to create a new column for the values, for example:
|Name |NON EXEMPT VALUE|EXEMPT VALUE|
|X |100 |200 |
I just don't know how how I would sort it whether it's in my Where clause or not.

Answer 1

Use a CASE statement within a SUM to only total NON EXEMPT, then EXEMPT, and select them as separate columns. Similar to the following (might need to add TOTAL_VALUE to the GROUP BY, or remove EXEMPTIONSTATUS)
SELECT
NAME
,SUM(CASE WHEN EXEMPTIONSTATUS = 2 THEN TOTAL_VALUE ELSE 0 END) AS 'NON EXEMPT VALUE'
,SUM(CASE WHEN EXEMPTIONSTATUS = 3 THEN TOTAL_VALUE ELSE 0 END) AS 'EXEMPT VALUE'
FROM ORDER_ACCOUNT JOIN ACCOUNT_INVOICE
WHERE ORDER_ACCOUNT.DATE BETWEEN 'M/D/YEAR' AND 'M/D/YEAR'
GROUP BY NAME, EXEMPTIONSTATUS
ORDER BY NAME ASC
EDIT: New code below adds new columns to your existing table. you will need to replace the #Test with your tables, but I believe this will get you what you're looking for.
SELECT
NAME,
EXEMPTIONSTATUS
,[TOTAL_VALUE]
,(SELECT SUM(CASE WHEN EXEMPTIONSTATUS = 2 THEN TOTAL_VALUE ELSE 0 END) FROM #Test t WHERE t.NAME = NAME) 'NON EXEMPT VALUE'
,(SELECT SUM(CASE WHEN EXEMPTIONSTATUS = 3 THEN TOTAL_VALUE ELSE 0 END) FROM #Test t WHERE t.NAME = NAME) 'EXEMPT VALUE'
FROM #Test
This gives me the following output
| NAME | EXEMPTIONSTATUS | TOTAL_VALUE | NON EXEMPT VALUE | EXEMPT VALUE |
| X | 2 | 100 | 100 | 200 |
| X | 3 | 200 | 100 | 200 |

Answer 2

Let's say your table structure is like this:
CREATE TABLE tab(ID int, Name nvarchar(20), ExemptionStatus int, TotalValue int);
INSERT INTO tab(ID, Name, ExemptionStatus, TotalValue) values (1, 'X', 2, 100);
INSERT INTO tab(ID, Name, ExemptionStatus, TotalValue) values (2, 'X', 3, 200);
So your data looks like this:
ID Name ExemptionStatus TotalValue
1 X 2 100
2 X 3 200
Then the query you'd use is:
SELECT NotExempted.Name,
NotExempted.NonExemptValue,
Exempted.ExemptValue
FROM (SELECT Name,
CASE
WHEN ExemptionStatus = 2 THEN TotalValue
END
AS 'NonExemptValue'
FROM #tab
) NotExempted
INNER JOIN (SELECT Name,
CASE
WHEN ExemptionStatus = 3 THEN TotalValue
END
AS 'ExemptValue'
FROM #tab
) Exempted ON NotExempted.Name = Exempted.Name
WHERE NotExempted.NonExemptValue IS NOT NULL
AND Exempted.ExemptValue IS NOT NULL
GROUP BY NotExempted.Name,
NotExempted.NonExemptValue,
Exempted.ExemptValue
You result will look like this :
Name NonExemptValue ExemptValue
X 100 200

Now, let's say you have data like this :
CREATE TABLE #tab(ID int, Name nvarchar(20), ExemptionStatus int, TotalValue int)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (1, 'X', 2, 100)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (2, 'X', 3, 200)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (3, 'X', 2, 1000)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (4, 'X', 3, 2000)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (5, 'X', 2, 1045)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (6, 'X', 3, 2045)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (7, 'X', 2, 1034)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (8, 'X', 3, 2023)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (9, 'X', 2, 1023)
INSERT INTO #tab(ID, Name, ExemptionStatus, TotalValue) values (10, 'X', 3, 2076)
which looks like this:
ID Name ExemptionStatus TotalValue
1 X 2 100
2 X 3 200
3 X 2 1000
4 X 3 2000
5 X 2 1045
6 X 3 2045
7 X 2 1034
8 X 3 2023
9 X 2 1023
10 X 3 2076
If you need to sum the total value up, then you can use the following query (which is a slight modification of the query above):
SELECT NotExempted.Name,
NotExempted.NonExemptValue,
Exempted.ExemptValue
FROM (SELECT Name,
CASE
WHEN ExemptionStatus = 2 THEN (SELECT SUM(TotalValue) FROM #tab WHERE ExemptionStatus = 2)
END
AS 'NonExemptValue'
FROM #tab
) NotExempted
INNER JOIN (SELECT Name,
CASE
WHEN ExemptionStatus = 3 THEN (SELECT SUM(TotalValue) FROM #tab WHERE ExemptionStatus = 3)
END
AS 'ExemptValue'
FROM #tab
) Exempted ON NotExempted.Name = Exempted.Name
WHERE NotExempted.NonExemptValue IS NOT NULL
AND Exempted.ExemptValue IS NOT NULL
GROUP BY NotExempted.Name,
NotExempted.NonExemptValue,
Exempted.ExemptValue
Your result will look like this :
Name NonExemptValue ExemptValue
X 4202 8344

Hope this helps!!!
