问题
So I have an acces table : Data
Data is made of :
- Client ID
- Product ID
- Sell Category ( exemple : Sell Dones, Sell Planed ,Forecast Sales) ,written all in letters
- Quantity sold .
- unitary price.
I am trying to build a single Acces query which would display things like :
|Client ID||Product ID||Total Sell Dones||Total Sell Planed||Total Forecast Sell||Quantity Sell Dones||Quantity Sell Planed||Quantity Forecast|
How can I do that ?
Like if I had only one type of sell and one single quantity I could simply do :
SELECT (sells*quantity) AS [Total Sells]
But the thing here is have different quantity and different types of sells could I put IF into the select ?
Something like :
Select (IF Data.Sell Category="Planned Sell" THEN quantity Sold*Unitary Price
ELSE 0) as [Total Planned Sell] , etc etc (for every single one ?
The thing is I am using acces 2003 and I dont think I can create a sql function in acces 2003 and use it in my select , but if I can I am willing to do so , else if I can only use "select,delete,update " in acces 2003 I guess I will have to do it like this
