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 )

I have a table called USER. This table has 2 columns as end_date, access_date. access_date is empty right now but i want to populate it like:
if end_date exists : access_date = end_date + 1 year (anway i can make that operation) but my problem i could not construct the cursor i have not use cursor logic before.
i need something like:
DELIMITER $$
CREATE PROCEDURE user_procedure ()
BEGIN
DECLARE v_finished INTEGER DEFAULT 0;
DECLARE v_user varchar(100) DEFAULT "";
-- declare cursor for user
DEClARE user_cursor CURSOR FOR
SELECT * FROM USER;
-- declare NOT FOUND handler
DECLARE CONTINUE HANDLER
FOR NOT FOUND SET v_finished = 1;
OPEN user_cursor;
get_user: LOOP
FETCH user_cursor INTO v_user;
IF v_finished = 1 THEN
LEAVE get_user;
END IF;
-- operation
-- something like:
set #end_date = select from cursor
update expiry... etcs
END LOOP get_user;
CLOSE user_cursor;
END$$
DELIMITER ;
CALL user_procedure();
but the problem i do not know how to define the cursor because as you see in example:
DECLARE v_user varchar(100) DEFAULT "";
i am pretty sure it is wrong and i try to fetch it into
FETCH user_cursor INTO v_user;
So how can i properly define the cursor and fetch as a whole row and make change ?
Edit: some people did not understand and claimed i have asked same question again, ok i will edit the real code, now as below according to people's comment. This update must be applied to each individual row.
set #key = 'bla bla';
delimiter $$
create procedure select_or_insert()
begin
IF EXISTS (select USER_EXPIRY_DATE from USER) THEN
update USER set ACCESS_EXPIRY_DATE = DATE_ADD(USER_EXPIRY_DATE, INTERVAL 1 YEAR);
ELSE IF EXISTS (select USER_START_DATE from USER) THEN
SET #start_date = (select USER_START_DATE from USER);
SET #start_date_to_be_added = aes_decrypt(#start_date,#key)
update USER set ACCESS_EXPIRY_DATE = DATE_ADD(USER_EXPIRY_DATE, INTERVAL 1 YEAR);
END IF;
end $$
delimiter ;
but in here for example:
ELSE IF EXISTS (select USER_START_DATE from USER)
is returning more than 1 row.
You don't need a cursor for that, you can simply use an update statement:
UPDATE User
SET access_date = DATE_ADD(end_date, INTERVAL 1 YEAR)
WHERE end_date IS NOT NULL
I need to write a stored procedure using mysql.
In the repeat loop showing below, if I use something as:
SET VDATEI=(SELECT A.DATEI FROM STAFF_CONVENIOS A WHERE
A.CONV_ID=CONVE AND A.STAFF_ID=MED LIMIT 1);
the stored procedure works well and I get a result set.
But, I need select into multiple variables. Something as:
SELECT
A.DATEI, A.DIAI, A.HORAI
INTO
VDATEI, VDIAI, VHORAI
FROM
STAFF_CONVENIOS A
WHERE
A.CONV_ID = CONVE AND A.STAFF_ID = MED
LIMIT 1;
In this case my stored procedure is broken I get no result set.
How to use select into to multiple variables into stored procedure with temporary tables?
My stored procedure is similar to:
CREATE PROCEDURE P_GETHORARIOS(
IN `MED` BIGINT,
IN `DATAREF` DATE,
IN `ESPEC` BIGINT,
IN `CONVE` BIGINT
)
BEGIN
DECLARE BDONE,BTEMP, BOCUP INT;
DECLARE DIA;
DECLARE VDIA,OK TINYINT;
DECLARE VDURACAO TINYINT;
DECLARE VDATEI DATE;
DECLARE VDIAI TINYINT;
DECLARE VHORAI TIME;
DECLARE VHORA, VHORAI,VHORAF TIME;
DECLARE CURS CURSOR FOR SELECT DIA,COALESCE(A.DURACAO,30) AS DURACAO, A.HINI FROM STAFF_ESCALA A
WHERE A.DIA=DIA;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET BDONE = 1;
DROP TEMPORARY TABLE IF EXISTS TBLRESULTS;
CREATE TEMPORARY TABLE IF NOT EXISTS TBLRESULTS (
DATA_AG DATE,
DIA TINYINT,
HORA TIME );
SET DIA=DAYOFWEEK(DATAREF);
OPEN CURS;
SET BDONE = 0;
REPEAT
SET OK=TRUE;
FETCH CURS INTO VDIA,VDURACAO,VHORAI;
-- SET VDATEI=(SELECT A.DATEI FROM STAFF_CONVENIOS A WHERE A.CONV_ID=CONVE AND A.STAFF_ID=MED LIMIT 1);
SELECT A.DATEI, A.DIAI,A.HORAI INTO VDATEI, VDIAI,VHORAI FROM STAFF_CONVENIOS A WHERE A.CONV_ID=CONVE AND A.STAFF_ID=MED LIMIT 1;
SET BTEMP=IF(VDATEI IS NULL,TRUE,FALSE);
SET OK=OK AND BTEMP ;
IF (OK) THEN
INSERT INTO TBLRESULTS VALUES (DATAREF,VDIA,VHORA);
ELSE INSERT INTO TBLRESULTS VALUES (VDATEI,VDIAI,VHORAI);
END IF;
UNTIL BDONE END REPEAT;
CLOSE CURS;
SELECT A.* FROM TBLRESULTS;
END
I have posted a sample of my problem. Here is the real stored procedure:

The problem is with the lines:

If I use "SET #EOK..." all works well.
If I use SELECT 1 INTO #EOK.. the problem appears.

You may have to use user/session variables (the #xyz kind). The documentation does not explicitly state such, but it only shows examples with them.
https://dev.mysql.com/doc/refman/5.7/en/select-into.html
If it is an issue with the NOT FOUND handler getting triggered from something other than the cursor, you could try structuring your code something like this (very pseudocode):
FETCH
WHILE( NOT DONE )
BEGIN
DO STUFF
SET DONE = FALSE
FETCH
END
I have a stored procedure like the following. There is an error showing at the update statement before the cursor declaration. When I remove the cursor statement, the stored procedure works fine. Why can't be there an update statement before the cursor statement?
DROP PROCEDURE IF EXISTS GenerateAlert;

Found the answer: The declaration statments must come before any other transactional statement in MySQL stored procedure.
SQL, missing end, but why? Second comment in the answer.
What am I doing wrong?
CREATE DEFINER=`root`#`localhost` PROCEDURE `getAllPoints`()
BEGIN
declare done1, done2, done3, done4, pointAlive BOOLEAN DEFAULT FALSE;
*lots of declaring*
...
*lots of declaring*
declare cur1 cursor for select id, Owner_idOwner, longitude, lat,x,y from Point;
declare continue handler for not found set done1= TRUE;
DROP TEMPORARY TABLE IF EXISTS TEMP;
CREATE temporary TABLE IF NOT EXISTS TEMP (
*lots of stuff*
)ENGINE=MEMORY;
open cur1;
mainLoop: loop
fetch cur1 into pointid, ownerid, pointlong, pointlat, pointx,pointy;
if done1 then
set done1 = FALSE;
close cur1;
leave mainLoop;
end if;
insert into TEMP (тут работает);
BLOCK2:BEGIN
** Black is working right with cursor #1***
END BLOCK2 ;
BLOCK3:BEGIN
** Black is working right with cursor #2***
END BLOCK3;
That's what's not working:
pointid declared int with value "18045" fetched from cur1 cursor
call isAlive(pointid,#Alive,#timeTill);
update TEMP set Open = #Alive, TimeTill= #timeTill where Point_id = pointid;
end loop mainLoop;
select * from TEMP;
After calling isAlive loop seems to be interrupted and select query returns only 1 row with correct value in Open and TimeTill column instead of ~1200rows with correct values when isAlive is not called
END
This is the isAlive stored procedure:
CREATE DEFINER=`root`#`localhost` PROCEDURE `isAlive`(IN iPoint_id int, INOUT Alive int, INOUT timeTill time)
BEGIN
declare pointAlive int;
select count(id) into pointAlive from Schedule where
day = dayofweek(curdate())-1
and Point_id = iPoint_id
and Start < curtime()
and Stop > curtime();
if poinTalive then
select pointAlive,timediff(Stop,curtime()) INTO Alive, timeTill
from Points.Schedule
where day = dayofweek(curdate()) -1
and Point_id = iPoint_id;
else
select pointAlive,timediff(str_to_date(concat(curdate(),' ',#starttime), "%Y-%m-%d %T"),now()) INTO Alive, timeTill
from Points.Schedule
where day = dayofweek(curdate()) -1
and Point_id = iPoint_id;
end if;
END
Can you tell me what am I doing wrong? How can I call isAlive for every pointid ? Thank you

You want to use a stored procedure but are using a function. There's a difference, you know?
Also I think you don't need a procedure at all, let alone a cursor. Cursors are expensive as hell.
Does this get you what you want?
