Can we use Select statement inside a loop in a Mysql Stored Procedure?
why is the code wrong
create procedure AbsentReportproc (INOUT fromdate DATETIME, INOUT todate DATETIME)
as
begin
DECLARE startdate DATE;
DECLARE enddate DATE;
DECLARE nofdays INT;
DECLARE counter INT;
DECLARE countdate DATE;
startdate=fromdate;
enddate=todate;
countdate=fromdate;
nofdays=DATEDIFF(DAY,startdate,endate);
counter=1;
while counter<=noofdays
loop
select CARDNO from test_prefixmaster
where CARDNO not in ( select CARDNO from test_prefixtransactions where Date(S_DateTime)=countdate)
set countdate=countdate+1;
set counter=counter+1;
end loop;
end//
Try this:
DELIMITER $$
DROP PROCEDURE IF EXISTS `AbsentReportproc`$$
CREATE DEFINER=`root`#`localhost` PROCEDURE `AbsentReportproc`(IN _fromdate DATETIME, IN _todate DATETIME)
BEGIN
CREATE TEMPORARY TABLE daterange (dte DATE);
SET #counter := -1;
WHILE (#counter < DATEDIFF(DATE(_todate), DATE(_fromdate))) DO
INSERT daterange VALUES (DATE_ADD(_fromdate, INTERVAL #counter:=#counter + 1 DAY));
END WHILE;
SELECT tp.cardno, tp.EMPCODE, tp.DEPARTMENT, GROUP_CONCAT(d.dte) Absentddate, COUNT(tp.cardno) Totalnoofabsentdates
FROM test_prefixmaster tp JOIN daterange d
LEFT JOIN test_prefixtransactions tpt ON tp.cardno = tpt.CARDNO AND DATE(S_DateTime) = d.dte
WHERE tpt.CARDNO IS NULL
GROUP BY tp.cardno;
DROP TABLE daterange;
END$$
DELIMITER ;
You didn't need a loop for this. You can do so:
SELECT
p.CARDNO,
COUNT(CARDNO) AS countdate
FROM test_prefixmaster p
INNER JOIN test_prefixtransactions t ON p.CARDNO = t.CARDNO
WHERE Date(t.S_DateTime) BETWEEN fromdate
AND todate
GROUP BY p.CARDNO;

i am trying to insert all date in daterange table within specific given date rane.here is my procedure but i am getting error and i can't solve it.
DELIMITER//
CREATE PROCEDURE example(IN sdate DATE, IN enddate DATE)
BEGIN
SET #sdate = sdate;
SET #enddate=enddate;
WHILE(#sdate < #enddate) DO
INSERT INTO daterange SET day = sdate;
sdate = DATE_ADD(sdate, INTERVAL 1 DAY);
END WHILE;
SELECT * FROM daterange;
END//;
DELIMITER ;
Try enter space into Delimiter and //
And your while have syntax erros, look at the fix procedure:
DELIMITER //
CREATE PROCEDURE example(IN sdate DATE, IN enddate DATE)
BEGIN
declare varDay date;
WHILE(sdate < enddate) DO
INSERT INTO daterange ([your-column]) values (varDay);
SET sdate = DATE_ADD(sdate, INTERVAL 1 DAY);
SET varDay = sdate;
END WHILE;
SELECT * FROM daterange;
END //;

I try to create following procedure:

I'm new in stored procedures.
How can I fix this error?
Declare all variables at the beginning, not in the middle of your code.
DROP PROCEDURE IF EXISTS my_super_procedure;
DELIMITER $$
CREATE PROCEDURE my_super_procedure(IN in_id VARCHAR(255), IN in_from_date timestamp, IN in_to_date timestamp)

WHILE tmp_date < in_to_date DO
SELECT count(*) as total_events FROM event e where e.scheduled between tmp_date and tmp_date + interval 1 day;
set tmp_date = DATE_ADD(tmp_date, INTERVAL 1 DAY);

I have the mysql version 5.5.38.
When I call a procedure that call a function inside there, handler condition its activated into function and raise up to procedure. I need that handler condition on function not affect the process on procedure. Included the function and procedure.
function:

I can't fix the problem, but I found a solution to replace the function, I capture empty result into IFNULL function and now I can set a specific value when select show me a empty result.
SELECT (
IFNULL(
(
SELECT ENDTLS.GALLONS
FROM TLS_TEMP_DATA ENDTLS
WHERE ENDTLS.FK_TANK = tank
AND ENDTLS.DATE LIKE ONCAT(DATE_FORMAT(DATE_ADD(DATE_FORMAT(INI_DATE, '%Y-%m-%d %H'), INTERVAL 1 HOUR), '%Y-%m-%d %H'),':%')
AND ENDTLS.REQUEST_TYPE = 1
)
, -1)
) INTO END_GAL;
So I'm trying to create a stored procedure in MySQL version 5.5.
I'm not sure what is wrong but what I want to accomplish is.
Get record From Table-A that over 7 days old. And then insert into Table-B, but I need to check if it is exist in Table B. If it is exists then skip, else Insert it.
So here is my code:
DROP PROCEDURE IF EXISTS `move_record`;
DELIMITER //
CREATE PROCEDURE `move_record`()
BEGIN
DECLARE done INT DEFAULT FALSE;
DECLARE dt DATETIME;
DECLARE uid,value BIGINT(20);
DECLARE category VARCHAR(30);
DECLARE data,comments VARCHAR(255);
DECLARE cancel TINYINT(1) DEFAULT NULL;
DECLARE curs CURSOR FOR SELECT `datetime`,user_id,category,data,comments,cancel FROM `record` WHERE `datetime` < DATE_SUB(CURDATE(), INTERVAL 7 DAY);
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
OPEN curs;
myloop: LOOP
FETCH NEXT FROM curs INTO dt,uid,category,data,comments,cancel;
IF done THEN
LEAVE myloop;
END IF;
IF NOT EXISTS (SELECT * FROM `record_arc`
WHERE record_arc.`datetime` = dt
AND record.user_id = uid )
INSERT INTO `record_arc` (`datetime`,user_id,category,data,comments,cancel) VALUES (dt,uid,category,data,comments,cancel);
END IF;
END LOOP myloop;
CLOSE curs;
DEALLOCATE curs;
END//
DELIMITER ;
Maybe you can do this without a loop.
INSERT INTO `record_arc`(
`datetime`,
user_id,
category,
data,
comments,
cancel
)
SELECT
`datetime`,
user_id,
category,
data,
comments,
cancel
FROM `record` r
WHERE
`datetime` < DATE_SUB(CURDATE(), INTERVAL 7 DAY)
AND NOT EXISTS(
SELECT 1
FROM `record_arc` r2
WHERE
r2.`datetime` = r.`datetime`
AND r2.user_id = r.user_id
)
Alias name you used it wrongly. Check the below code
IF NOT EXISTS (SELECT 1 FROM `record_arc`
WHERE record_arc.`datetime` = dt
AND record_arc.user_id = uid )
