Hello,
I'm an Access/SQL novice and I have an sql problem:
I have the following table Price:
FuelID PriceDate Price
LPG 1/05/2007 0,2
LPG 13/05/2007 0,21
SPS 2/05/2007 1,1
SPS 15/05/2007 1,08
And I have to make the following query:
FuelID PriceDate_from PriceDate_To Price
LPG 1/05/2007 13/05/2007 0,2
SPS 2/05/2007 15/05/2007 1,1
LPG 13/05/2007 0,21
SPS 15/05/2007 1,08
I tried this:
SELECT FuelID, min(FuelDate) AS Pricedate_from, max(FuelDate) AS
PriceDate_to FROM Price GROUP BY FuelID;
Problem is, when I put Price in the select, I get the error 'Price not part
of an aggregate function' :s
Eitherway, it doesnt work, I only have one FuelDate_from and one FuelDate_to
if I use min & max. While there should be several from...to... dates for a
particular fuel.
How can I solve this ?
