BUG:
----
We have an SQL statement that is giving wrong output.
Here is an example of the whole statement:
SELECT
*, Date_Part('Month', CAST ('5/25/2001' AS DATE))
- Date_Part('Month', purchasedate ) + 1 AS thismonth
FROM customers
WHERE CAST('5/25/2001' AS DATE) - CAST ('12 months' AS INTERVAL) <
purchasedate
AND purchasedate <= CAST ('5/25/2001' AS DATE)
AND 25 <= Date_Part('Day', purchasedate)
AND Date_Part('Day', purchasedate) <= 25
AND merchantnumber != 'odc12'
ORDER BY thismonth, id_num
Here is a simple example:
SELECT DATE_PART('DAY', CAST('04/1/2001' AS DATE)) as dayofmonth
dayofmonth
----------
31
Why does April 1st display as May 31st?
Here is the table def:
CREATE TABLE "customers" (
"id_num" int4 DEFAULT nextval('customers_id_num_seq'::text) NOT
NULL,
"merchantnumber" character varying(9),
"producttype" character varying(7),
"purchasedate" date,
"emailaddress" character varying(60),
"firstname" character varying(25),
"lastname" character varying(50),
"customerfullname" character varying(40),
"salesordernumber" character varying(20),
"notes" character varying(80)
);
