This might not be the most elegant solution but it works. Create a function that sorts the Number then you can do a GROUP BY.

IF OBJECT_ID (N'dbo.SortNumer', N'FN') IS NOT NULL
DROP FUNCTION dbo.SortNumer;
GO
CREATE FUNCTION dbo.SortNumer(@number INT)
RETURNS VARCHAR(100)
AS
BEGIN
DECLARE @sortnums TABLE (digit VARCHAR(1));
DECLARE @sortString VARCHAR(3) = CAST(@number AS VARCHAR(100));
DECLARE @length INT = LEN(@sortString);
DECLARE @i INT = 1;
DECLARE @sorted VARCHAR(100) = '';
WHILE (@i <= @length)
BEGIN
INSERT INTO @sortnums VALUES(SUBSTRING(@sortString,@i,1));
SET @i = @i + 1;
END;
SELECT @sorted = @sorted + digit FROM @sortnums ORDER BY digit
RETURN @sorted
END;
GO
SELECT dbo.SortNumer(231)

/*
ID Number Amount
1 123 10
2 213 20
3 321 10
4 123 60
5 122 30
*/
IF OBJECT_ID('tempdb..#Amount') IS NOT NULL
DROP TABLE #Amount
CREATE TABLE #Amount (
ID INT IDENTITY(1,1),
Number INT,
Amount INT
)
IF OBJECT_ID('tempdb..#TempAmount') IS NOT NULL
DROP TABLE #TempAmount
CREATE TABLE #TempAmount (
ID INT,
Number INT,
Amount INT
)
INSERT INTO #Amount(Number, Amount)
VALUES (123, 10),
(213, 20),
(321, 10),
(123, 60),
(122, 30)
INSERT INTO #TempAmount (ID, Number, Amount)
SELECT ID, CAST(dbo.SortNumer(Number) AS INT), Amount
FROM #Amount
SELECT Number, SUM(Amount) AS Total
FROM #TempAmount
GROUP BY Number

Results

Number Total
----------- -----------
122 30
123 100

That is why I suggested using the GROUP BY phrase. Not off the mark its same thing you suggested.

The links I provided show exactly the same type of solution but a bit more elegant.

And allow the user to review a few approaches to the problem to solidify their knowledge.

You might want to re-read the OPs original question. The basis of the problem is not GROUP BY how to group all combinations of 123, 231, and 321. Neither of the posted links cover how to do this.

You will need to use the GROUP BY phrase on the number field then total the Amount column.

Hi march11,

I appreciate your response, though that's not what i'm looking for. I know how to group data. :) My problem is to group the set of number combination in the column. I think what Mgebhard solution will work.

Thank you.

## Sum of amount for all set of number combination

Mar 12, 2017 06:06 AM|vinz|LINK

Hello SQL Experts!

I am no sql guru and I have trouble getting the result i wanted. I have tried searching the web for the solution but to no avail. :(

Here's the situation. Given, I have the following table with simple data:

ID Number Amount

1 123 10

2 213 20

3 321 10

4 123 60

5 122 30

I want to get the summary of that table by summing the Amount of numbers to result to this:

Number Total

123 100

122 20

The first combination should display in the summary. The output above displays the Number '123' since '213' and '321' are a combination of '123'.

I appreciate any guidance. Thank you in advance. :)

You will need to use the GROUP BY phrase on the number field then total the Amount column.

This might not be the most elegant solution but it works. Create a function that sorts the Number then you can do a GROUP BY.

Your answer is off the mark. The OP requested a design that groups all combinations of the Number field; 123, 231, and 321.
