I have a database for a game server and another one for web.
I would like to call a procedure which take a data from a table of the web database.
I have seen many examples like this 'db1.dbo.table_name' but I don't know what is dbo (Data Base Owner ?)
Here is my actual procedure
CREATE DEFINER=`root`#`localhost` PROCEDURE `donationCheck`()
BEGIN
UPDATE `gameserver.players` SET `donatorlvl` = (SELECT `grade` FROM `web.donations` as dona WHERE dona.steamid = player.playerid) where steamid = '76561198125956777';
END
The error is that gameserver.web.donations does'nt exists (normal);
Sorry for my bad english.
CREATE DEFINER=`root`#`localhost` PROCEDURE `donationCheck`()
BEGIN
UPDATE gameserver.players a
INNER JOIN web.donations b ON a.playerid = b.steamid
SET a.donatorlvl = b.grade;
END

I was getting an error of "Delimiter" is not valid at this position, expecting CREATE" as I was writing a stored procedure and couldn't figure out the cause. I think it might be an issue with MySQL workbench possibly, because the following code gives the same error but was copied straight off of this website.
DELIMITER $$
CREATE PROCEDURE GetTotalOrder()
BEGIN
DECLARE totalOrder INT DEFAULT 0;
SELECT COUNT(*)
INTO totalOrder
FROM orders;
SELECT totalOrder;
END$$
DELIMITER ;
Edit: My real stored procedure is:
DELIMITER //
CREATE PROCEDURE GetSimilar(inputdate char(10))
BEGIN
Declare id(tinyint) DEFAULT 0;
Set id := (select t.IdTimelineinfo
From timelineinfo t
WHERE t.Date = inputdate);
SELECT t.Date From timelineinfo t where t.date = inputdate;
SELECT o.Name, o.Race, o.Sex, o.IdOfficer
FROM timelineinfo
JOIN timelineinfo_officer ON timelineinfo.IdTimelineinfo = timelineinfo_officer.IdTimelineinfo
JOIN officers o ON timelineinfo_officer.IdOfficer = o.IdOfficer
WHERE timelineinfo.IdTimelineinfo = id
UNION
SELECT s.IdSubject, s.Name, s.Race, s.Sex
FROM timelineinfo
JOIN timelineinfo_subject ON timelineinfo.IdTimelineinfo = timelineinfo_subject.IdTimelineinfo
JOIN subjects s ON timelineinfo_subject.IdSubject = s.IdSubject
WHERE timelineinfo.IdTimelineinfo = id;
UNION
Select *
From media m
Where (m.IdTimelineinfo = id);
END //
DELIMITER ;
Watch out where you edit the procedure SQL code. There's a dedicated routine object editor (just like there are for tables, triggers, views etc.), which only accept SQL code for their associated object type. Hence they don't need a delimiter and even signal an error if you use one.
On the other hand you can always directly edit SQL code in the SQL IDE code editors, where no such special handling is implemented. In this case you need the delimiter.
I have procedure:
CREATE PROCEDURE channge_max_priority()
BEGIN
update feeds set max_post_priority =
(
select max(feed_posts.priority)
from feed_posts
where feed_posts.feed_id = feed_id
)
where feeds.id = feed_id;
END
And I want to create three triggers:
CREATE TRIGGER feed_post_after_test AFTER INSERT (And update and delete ) ON feed_posts
FOR EACH ROW EXECUTE PROCEDURE change_max_priority();
Procedure work correctly, but when I try start trigger - I get error:
Error in query (1064): Syntax error near 'PROCEDURE change_max_priority()' at line 2
You have a double nn in name procedure :
replace :
CREATE PROCEDURE channge_max_priority()
by
CREATE PROCEDURE change_max_priority()
Try changing the update statement to use a join instead, this should work:
update feeds
set max_post_priority = max(feed_posts.priority)
FROM feeds f
INNER JOIN feed_posts fp on feed_posts.feed_id = f.feed_id
Group BY f.feed_id
In mysql, a procedure is executed using CALL:
CREATE TRIGGER feed_post_after_test AFTER INSERT (And update and delete ) ON feed_posts
FOR EACH ROW CALL change_max_priority();
I don't see why you should execute the procedure for each row though, the whole feeds table is update in one procedure call.
Also not sure the last where feeds.id = feed_id; (just before END) is correct in the procedure.
I have a table that holds a bunch of values for an order, I can do basic calculations on it until I get to a percentage. Right now I have my query as follows
declare #MyNumber decimal
set #MyNumber = (select SalesTax from [OrderHeader] where OrderHeaderID = 20)
select
sum(o.MaterialPrice) as "MatPrice",
sum(o.LaborPrice) as "LaborPrice",
sum(o.MaterialCost) as "MaterialCost",
sum(isnull(o.MaterialPrice,0)) - sum(isnull(o.MaterialCost,0)) - sum(isnull(o.LaborPrice,0)) * #MyNumber as "RESULT"
from [OrderDetail] o
inner join [OrderHeader] oh on oh.OrderHeaderID = o.OrderHeaderID
where o.OrderHeaderID = 20

In the code below I'm trying to create a trigger which inserts 'incidentimg' table id along with an image path if the user of the web application did not upload a image with the form belonging to 'incidentreport' table, however, I'm only getting the error "MySQL said: #1422 - Explicit or implicit commit is not allowed in stored function or trigger"
DROP TRIGGER IF EXISTS `insertImage`;
CREATE TRIGGER `insertImage` AFTER INSERT ON `incidentreport`
FOR EACH ROW
BEGIN
IF(SELECT incidentimg.incidentImgId FROM incidentimg
LEFT JOIN incidentreport ON incidentimg.imgs_incidentReportId = incidentreport.incidentReportId
WHERE incidentimg.incidentImgId IS NULL)
THEN INSERT INTO incidentimg(incidentImgId, imgUrl)values(NEW.incidentReportId, 'images/no-image.png');
END IF;
END
;
Here are the tables being used
Can someone assist me on how to correct this problem
I finally got the code to work. Now the code will check whether 'incidentimg' table has all the 'incidentReportId' that the 'incidentreport' table has, and if it doesn't then the last inserted id from the 'incidentreport' table along with a default image path will be inserted into 'incidentimg' table AFTER INSERT.
CREATE TRIGGER insertImage AFTER INSERT ON incidentreport
FOR EACH ROW
BEGIN
IF(SELECT incidentreport.incidentReportId
FROM incidentreport
LEFT JOIN incidentimg ON incidentreport.incidentReportId = incidentimg.imgs_incidentReportId
WHERE incidentimg.imgs_incidentReportId IS NULL)
THEN INSERT INTO incidentimg(imgs_incidentReportId, imgUrl) VALUES(NEW.incidentReportId, 'images/no-image.png');
END IF;
END
I am not much sure but I am guessing that probably it's because of the IF .. THEN conditional INSERT. Try modifying your INSERT statement with an EXISTS like
DROP TRIGGER IF EXISTS `insertImage`;
CREATE TRIGGER `insertImage` AFTER INSERT ON `incidentreport`
FOR EACH ROW
BEGIN
INSERT INTO incidentimg(incidentImgId, imgUrl)
SELECT NEW.incidentReportId, 'images/no-image.png'
FROM DUAL WHERE EXISTS (
SELECT 1 FROM incidentimg
LEFT JOIN incidentreport
ON incidentimg.imgs_incidentReportId = incidentreport.incidentReportId
WHERE incidentimg.incidentImgId IS NULL
)
END;
I'm fairly new to SQL in general and even more so to MySQL and I've hit a stumbling block. I'm attempting to use a procedure to copy the value of one field to another if the original field is not null, this procedure is then called by triggers whenever the table is updated or has a new row inserted into it. Here is what I have so far:
-- WORK_NOTES_PROCEDURE - This copies the contents of the estimate notes to the work order notes if the original estimate had any notes with it.
DROP PROCEDURE IF EXISTS 'WORK_NOTES_PROCEDURE';
DELIMITER $$
CREATE PROCEDURE WORK_NOTES_PROCEDURE()
BEGIN
DECLARE var_temp VARCHAR(50);
SET var_temp := (SELECT ESTIMATE_NOTES FROM ESTIMATES WHERE ESTIMATES.ESTIMATE_NUMBER = WORK_ORDERS.ESTIMATE_NUMBER);
IF var_temp IS NOT NULL THEN
UPDATE WORK_ORDERS SET WORK_ORDER_NOTES = var_temp WHERE WORK_ORDERS.ESTIMATE NUMBER = ESTIMATES.ESTIMATE_NUMBER;
END IF;
END$$
DELIMITER ;
Absolutely any help would be appreciated, the error I'm getting is a syntax error for the line where I'm assigning a value to var_temp.
try,
SET var_temp = (SELECT ESTIMATE_NOTES
FROM ESTIMATES INNER JOIN WORK_ORDERS
ON ESTIMATES.ESTIMATE_NUMBER = WORK_ORDERS.ESTIMATE_NUMBER
LIMIT 1);
