Need to convert 1 column into multiple columns

J

Java

Hi, I have a table that has a column called ShipDate. I need to have
ShipDate in multiple columns - Date1, Date2, Date3, etc... (not the actual
date as the column).
The cross tab gives me the actual date as column which is not what is
needed.

This is just a sample. I'm not sure why this is needed but it is being
requested of me.

MyTable
CustomerID ProductID Quantity ShipDate
123 T100 5 8/23/2008
123 T100 5 8/24/2008
123 T100 5 8/25/2008
123 T200 10 8/23/2008
123 T200 10 8/24/2008
123 T200 10 8/25/2008
123 T300 15 8/23/2008

One way is to use a Ranking in a Group query to produce a temp table then
crosstab query off that.

SELECT Q.CustomerID, Q.ProductID, Q.Quanity, Q.ShipDate, (SELECT COUNT(*)
FROM [MyTable] Q1
WHERE Q1.[CustomerID] = Q.[CustomerID]
AND Q1.[ProductID] = Q.[ProductID]
AND Q1.[ShipDate] < Q.[ShipDate])+1 AS Rank INTO MyTable_ShipOrder
FROM MyTable AS Q
ORDER BY Q.CustomerID, Q.ProductID, Q.Quanity, Q.ShipDate;

TRANSFORM First(MyTable_ShipOrder.ShipDate) AS FirstOfShipDate
SELECT MyTable_ShipOrder.CustomerID, MyTable_ShipOrder.ProductID,
MyTable_ShipOrder.Quanity
FROM MyTable_ShipOrder
GROUP BY MyTable_ShipOrder.CustomerID, MyTable_ShipOrder.ProductID,
MyTable_ShipOrder.Quanity
PIVOT "Date" & [Rank];

Here's my thinking but I haven't fully figured it out.

If you could add a column on to your original table of "DateCounter" and had
it iterate per CustomerID

MyTable
CustomerID ProductID Quantity
ShipDate DateCount
123 T100 5 8/23/2008 Date1
123 T100 5 8/24/2008 Date2
123 T100 5 8/25/2008 Date3
123 T200 10 8/23/2008 Date1
123 T200 10 8/24/2008 Date2
123 T200 10 8/25/2008 Date…
123 T300 15 8/23/2008 Date…

then you could pivot off that DateCount Column

Karl,

You know way too much about this stuff! Great answer. I had the concept
but not the know how. Another trinket to add to my knowledge base.

I was twiddling this around in my head and hoping someone would come along
with the answer.

Thanks!
