SIMPLE SQL SELECT INTO GRAPH - sql

Question

I am having trouble outputting an SQL Select Statement to my XML to be used for my Graph
I have these results
December 2011 470 FRESENIUS
January 2012 434 FRESENIUS
February 2012 278 FRESENIUS
February 2012 2 STORESID
I need to output them like this so I can loop my Code and generate the XML
Month Year FRESNIUS STORESID
December 2011 470 0
January 2012 434 0
February 2012 278 2
take note i did not include the headers, these are all column results.
and also, STORESID and FRESNIUS are not STATIC Values. Multiple Storers Exists so I needed to Expand my number of Columns also , Dynamically.
I kinda need to output the second one to generate the XML properly thru PHP which I already have. Or are there any other proper way.
Thanks.
query below for the output i was talking about
SELECT
DATENAME(month, orderdate) + ' ' + CAST(Year(orderdate) AS VARCHAR(4)) AS 'Month Year' ,
count(*) 'Number of Orders',
storerkey
FROM orders
GROUP BY
storerkey,
DATENAME(month, orderdate) + ' ' + CAST(Year(orderdate) AS VARCHAR(4)),
CAST(Year(orderdate) AS VARCHAR(4)) + RIGHT('0' + CAST(Month(orderdate) AS VARCHAR(2)),2)
ORDER BY
storerkey,
CAST(Year(orderdate) AS VARCHAR(4)) + RIGHT('0' + CAST(Month(orderdate) AS VARCHAR(2)),2)

Answer 1

I am not 100% certain of the XML output you need but you can take advantage of SQL-Servers FOR XML clause and PIVOT function. This should get you started:
CREATE TABLE #Test (GraphDate DATETIME, Value INT, Type VARCHAR(50))
INSERT #Test VALUES
('01/12/2011', 470, 'FRESENIUS'),
('01/01/2012', 434, 'FRESENIUS'),
('01/12/2012', 278, 'FRESENIUS'),
('01/02/2012', 2, 'STORESID')
SELECT DATEPART(YEAR, GraphDate) [Year],
DATENAME(MONTH, GraphDate) [Month],
ISNULL(FRESENIUS, 0) [FRESENIUS],
ISNULL(STORESID, 0) [STORESID]
FROM #Test
PIVOT
( SUM(Value)
FOR Type IN ([FRESENIUS], [STORESID])
) PivotTable
FOR XML PATH('row'), ROOT
DROP TABLE #Test
EDIT
The below is the basic query you have asked for based on the query you have given.
SELECT DATENAME(MONTH, OrderDate) + ' ' + DATENAME(YEAR, OrderDate) [MonthYear],
ISNULL(FRESENIUS, 0) [FRESENIUS],
ISNULL(STORESID, 0) [STORESID]
FROM Orders
PIVOT
( COUNT(StorerKey)
FOR StorerKey IN ([FRESENIUS], [STORESID])
) PivotTable
ORDER BY DATEPART(YEAR, OrderDate), DATEPART(MONTH, OrderDate)
EDIT 2
I don't think PIVOT is supported by SQL-Server 2000. You will need to use aggregate functions:
SELECT DATENAME(MONTH, OrderDate) + ' ' + DATENAME(YEAR, OrderDate) [MonthYear],
COUNT(CASE WHEN StorerKey = 'FRESENIUS' THEN 1 END) [FRESENIUS],
COUNT(CASE WHEN StorerKey = 'STORESID' THEN 1 END) [STORESID]
FROM Orders
GROUP BY DATEPART(YEAR, OrderDate), DATEPART(MONTH, OrderDate), DATENAME(YEAR, OrderDate), DATENAME(MONTH, OrderDate)
ORDER BY DATEPART(YEAR, OrderDate), DATEPART(MONTH, OrderDate)
I think some FOR XML functionality is still available though so you may still be able to output your XML directly from SQL.
EDIT 3
DECLARE #SQL NVARCHAR(2000)
SELECT #SQL = ISNULL(#SQL, '') + ', COUNT(CASE WHEN StorerKey = ''' + StorerKey + ''' THEN 1 END) [' + StorerKey + ']'
FROM ( SELECT DISTINCT StorerKey
FROM Orders
) Keys
SET #SQL = 'SELECT DATENAME(MONTH, OrderDate) + '' '' + DATENAME(YEAR, OrderDate) [MonthYear]' + #SQL +
' FROM Orders
GROUP BY DATEPART(YEAR, OrderDate), DATEPART(MONTH, OrderDate), DATENAME(YEAR, OrderDate), DATENAME(MONTH, OrderDate)
ORDER BY DATEPART(YEAR, OrderDate), DATEPART(MONTH, OrderDate)'
EXECUTE SP_EXECUTESQL #SQL

Answer 2

You could join the table to itself. If I make assumptions about the column names, assume that either the FRESNIUS or STORESID could be absent, and use common table expressions (untested!):
WITH date_fresnius AS (
SELECT [Month Year], FRESNIUS
FROM original_table
)
, date_storesid AS (
SELECT [Month Year], STORESID
FROM original_table
)
SELECT
ISNULL( f.[Month Year], s.[Month Year]) AS [Month Year]
, ISNULL( f.FRESNIUS, 0 ) AS FRESNIUS
, ISNULL( s.STORESID, 0 ) AS STORESID
FROM
date_fresnius f
FULL OUTER JOIN date_storesid s ON (f.[Month Year] = s.[Month Year])
If you always have a FRESNIUS record you can use a LEFT JOIN instead.

Answer 3

Based on your query:
SELECT
DATENAME(MONTH, orderdate) + ' ' + CAST(YEAR(orderdate) AS VARCHAR(4)) AS [Month Year]
COUNT(CASE storerkey WHEN 'FRESNIUS' THEN 1 END) AS FRESNIUS,
COUNT(CASE storerkey WHEN 'STORESID' THEN 1 END) AS STORESID
FROM orders
GROUP BY YEAR(orderdate), MONTH(orderdate), DATENAME(MONTH, orderdate)
ORDER BY YEAR(orderdate), MONTH(orderdate)
Output:
Month Year FRESNIUS STORESID
December 2011 470 0
January 2012 434 0
February 2012 278 2
