I wish to build a table based on values from another table.
I need to populate a table between two dates from another table. Using
the START_DT and END_DT, create records between those dates.
I need a new column that is the days between the date and the MID_DT
The data I wish to end with would look something like this:
PERIOD DATE DAY_NO
200602 2005-07-06 -89
200602 2005-07-07 -88
200602 2005-07-08 -87
<...>
200602 2005-10-02 -2
200602 2005-10-03 -1
200602 2005-10-04 0
200602 2005-10-05 1
<...>
200602 2005-12-18 75
CREATE TABLE "dbo"."tblDates"
("PERIOD" CHAR(6) NOT NULL,
"START_DT" DATETIME NULL,
"MID_DT" DATETIME NULL,
"END_DT" DATETIME NOT NULL)
INSERT INTO tblDates VALUES('200505',2005-04-12,2005-07-05,2005-09-12)
INSERT INTO tblDates VALUES('200602',2005-07-06,2005-10-03,2005-12-18)
INSERT INTO tblDates VALUES('200603',2005-10-04,2006-01-17,2006-03-27)
INSERT INTO tblDates VALUES('200604',2006-01-18,2006-04-10,2006-06-19)
INSERT INTO tblDates VALUES('200605',2006-04-11,2006-07-04,2006-09-11)
INSERT INTO tblDates VALUES('200702',2006-07-05,2006-10-02,2006-12-18)
