SQL select statement with increment
- by Matt
Currently I'm using a for statement in PHP to get all the months for this SQL statement, but would like to know if I can do it all with SQL.
Basically I have to get the average listing price, and the average selling price for each month going back 1 year where the sellingdate = the month.
simple with PHP, but that creates 12 database hits.
I'm trying the sql statment below, but it returns listings totally out of order
SELECT
avg(ListingPrice),
avg(SellingPrice),
count(ListingDate),
DATE(SellingDate) as date,
MONTH(SellingDate) as month,
YEAR(SellingDate) as year
FROM `rets_property_resi`
WHERE Area = '5030'
AND Status = 'S'
AND SellingDate
Output:
867507.142857 877632.492063 63 1996-12-24 12 1996
971355.833333 981533.333333 60 1997-11-18 11 1997

799484.615385 791551.282051 39 1997-01-15 1 1997
As you can see, it pulls from random dates, I need to to pull from 2010-03, 2010-02, 2010-01, etc...
any help is appreciated!
