MySQL stored proc WHILE give only last result - mysql

Question

I want to extract a count for every Date between two dates (#sdate,#edate) but it gives me only the count for the last day and not for all days.
How can i output all results? Here is my stored proc.
DELIMITER $$
USE `cmd_storeinfo`$$
DROP PROCEDURE IF EXISTS `test2`$$
CREATE DEFINER=`USER`#`%` PROCEDURE `test2`()
BEGIN
SET #sdate = (DATE_SUB(CURDATE(), INTERVAL 6 MONTH));
SET #edate = (CURDATE());
SET #x='';
SET #Y='';
WHILE #sdate <= #edate DO
SELECT COUNT(*) INTO #y
FROM cmd_storeinfo.strinfo
WHERE LiveDate <= #sdate AND DeinstallDate >= #sdate OR DeinstallDate IS
NULL AND LiveDate IS NOT NULL
AND CHAIN != 1 && CHAIN != 2 && CHAIN != 999
GROUP BY #sdate
SET #x = #sdate;
SET #sdate = (DATE_ADD(#sdate, INTERVAL 1 DAY));
END WHILE;
SELECT #x,#y;
END$$
DELIMITER ;
Thanks for you help.

Answer 1

You should try to use temporary table. Here is a nice answer about it.
Something like this could work:
DELIMITER $$
USE `cmd_storeinfo`$$
DROP PROCEDURE IF EXISTS `test2`$$
CREATE DEFINER=`USER`#`%` PROCEDURE `test2`()
BEGIN
CREATE TEMPORARY TABLE tmpTable (currentDate DATE, startDate INT);
SET #sdate = (DATE_SUB(CURDATE(), INTERVAL 6 MONTH));
SET #edate = (CURDATE());
SET #x='';
SET #Y='';
WHILE #sdate <= #edate DO
INSERT INTO tmpTable (currentDate, startDate)
SELECT #sdate, COUNT(*)
FROM cmd_storeinfo.strinfo
WHERE LiveDate <= #sdate AND DeinstallDate >= #sdate OR DeinstallDate IS
NULL AND LiveDate IS NOT NULL
AND CHAIN != 1 && CHAIN != 2 && CHAIN != 999
GROUP BY #sdate
SET #sdate = (DATE_ADD(#sdate, INTERVAL 1 DAY));
END WHILE;
SELECT * FROM tmpTable;
DROP TEMPORARY TABLE IF EXISTS tmpTable;
END$$
DELIMITER ;

Answer 2

You should use Temporary table to store all values.
DELIMITER $$
USE `cmd_storeinfo`$$
DROP PROCEDURE IF EXISTS `test2`$$
CREATE DEFINER=`USER`#`%` PROCEDURE `test2`()
BEGIN
SET #sdate = (DATE_SUB(CURDATE(), INTERVAL 6 MONTH));
SET #edate = (CURDATE());
SET #x='';
SET #Y='';
CREATE TEMPORARY TABLE tmpTable (x datetime,y bigint); -- creating tmp table
WHILE #sdate <= #edate DO
SELECT COUNT(*) INTO #y
FROM cmd_storeinfo.strinfo
WHERE LiveDate <= #sdate AND DeinstallDate >= #sdate OR DeinstallDate IS
NULL AND LiveDate IS NOT NULL
AND CHAIN != 1 && CHAIN != 2 && CHAIN != 999
GROUP BY #sdate
SET #x = #sdate;
insert into tmpTable (x,y) values (#x,#y); -- inserting values
SET #sdate = (DATE_ADD(#sdate, INTERVAL 1 DAY));
END WHILE;
SELECT x,y from tmpTable order by x; -- output temp table results
END$$
