I've been wrapping my head around this SQL statement I'm trying to make and I've reached a wall so to speak, if you could lend any advise as to what I am doing wrong that would be a big help. I get the error around the 2nd where statement but I dont really expect the last part of the code to work yet.
CREATE TRIGGER UpdateScores
AFTER INSERT ON CharSheet FOR EACH ROW
begin
DECLARE id_exists Boolean;
SELECT
1
INTO
#id_exists
FROM
ScoresTable
WHERE
ScoresTable.PlayerID= NEW.PlayerID;
IF #id_exists = 1
THEN
UPDATE
ScoresTable
SET
Exp = :New.Exp;
WHERE
ScoresTable.PlayerID = :NEW.PlayerID;
END IF;
IF #id_exists = 0
THEN
-- I don't expect this part to work yet.
INSERT INTO ScoresTable VALUES (:New.PlayerID, :New.Race, :New.Class, :New.Exp);
END IF;
END;
$$
The problem is in this block of code:
THEN
UPDATE
ScoresTable
SET
Exp = :New.Exp;
WHERE
ScoresTable.PlayerID = :NEW.PlayerID;
END IF;
Remove the semicolon at the end of the set statement.

Here is my trigger:
DELIMITER //
CREATE TRIGGER trg_pic_hours
AFTER INSERT ON CREW
FOR EACH ROW
BEGIN
IF NEW.CREW_JOB = 'Pilot' THEN
UPDATE PILOT
SET PIL_PIC_HOURS = PIL_PIC_HOURS+(SELECT CHAR_HOURS_FLOWN FROM CHARTER
WHERE CHAR_TRP = NEW.CHAR_TRP)
WHERE EMP_NUM = NEW.EMP_NUM;
END IF;
END;
It errors out on NEW.CHAR_TRP but if I remove the NEW it processes but does not work correctly. Any idea why?
I want to make a trigger that prevent inserting overlaping dates. For example:
If I have an offer "Oferta" with the date from 1/3/2016 to 5/3/2016, I can't insert a new offer with the date 2/3/2016 to 4/3/2016 or 4/3/2016 to 7/3/2016
My SELECT checks that condition I believe. What I don't know how to do is to make an error if such happens. I'm new to triggers and Im having syntax errors, I checked triggers syntax but couldnt find the problem...
DELIMITER $$
CREATE TRIGGER tri_check_date_overlap BEFORE INSERT ON Oferta
FOR EACH ROW
BEGIN
IF EXISTS(
SELECT * FROM Oferta WHERE
(new.morada = morada AND new.codigo = codigo
AND ((new.data_inicio BETWEEN data_inicio AND data_fim)
OR new.data_fim BETWEEN data_inicio AND data_fim)
)
)
/*CALL raise_application_error(3001, 'Not odd number!'); */
DECLARE msg varchar(255);
set msg = concat('Error: That right is not allowed!', cast(new.right as char));
signal sqlstate '45000' set message_text = msg;
END $$
DELIMITER ;
Your logic is ok, I think you just missed the 'then' condition after 'if' and 'end if' before the end of the trigger.
Following is the trigger I've written :
CREATE TRIGGER `test_BINS` BEFORE INSERT ON `phpfox_user` FOR EACH ROW
IF new.`full_name` = '' THEN SET new.`full_name` = NULL; END IF; END;
Following is the screen shot of the same:
Following is the image of error message that came :
Please somebody help me in adding this trigger.
DELIMITER $$
CREATE TRIGGER test_BINS BEFORE INSERT ON phpfox_user
FOR EACH ROW BEGIN
IF (NEW.full_name = '') THEN
SET NEW.full_name = NULL;
END IF;
END$$
DELIMITER ;
but if you want to add it using pma-interface, just place there this definition:
BEGIN
IF (NEW.full_name = '') THEN
SET NEW.full_name = NULL;
END IF;
END
The message is clear here. Whatever is present in the line 1 of your first image is not needed, as the information is already provided above.
Technically, your code tries to create a trigger inside another trigger. Remove the line 1 and it will be fine.
This should be the query:
FOR EACH ROW IF :new.full_name = '' THEN :new.full_name := NULL; END IF; END;
I am trying to run a SQL query, but something is messed up and I can't get below query to check if the data exists or not in the specified table.
The code I have is:
IF EXISTS(SELECT brth_day FROM sms.birthdaycheck WHERE brth_day = '2015-02-10')
THEN
BEGIN
UPDATE sms.birthdaycheck SET cnt = 1 WHERE brth_day = '2015-02-10'
END
ELSE
BEGIN
INSERT INTO sms.birthdaycheck(cnt,brth_day) VALUES (1,'2015-02-10')
END
END IF;
Edited solution :
delimiter ;;
create procedure XYZ(...parameters...)
begin
if exists(
SELECT brth_day FROM sms.birthdaycheck WHERE brth_day = '2015-
02-10')
then
UPDATE sms.birthdaycheck SET cnt = 1 WHERE brth_day = '2015-02-10';
else
INSERT INTO sms.birthdaycheck(cnt,brth_day) VALUES (1,'2015-02-10');
end if;
end;;
In MySQL, if control block must used inside a function or stored procedure.
So you need to rewrite your query:
I'm trying to write a trigger with mysql but it gives me several error. The last one has no description (MySQL says only Error!) and so i'm here to ask for your help

CREATE TRIGGER SellStockTrigger
AFTER INSERT ON UtenteHaAzione
FOR EACH ROW
BEGIN
DECLARE BUD DOUBLE;
DECLARE SOMMA DOUBLE;
SET BUD=(SELECT BUDGET
FROM UTENTE
WHERE CODUTENTE = NEW.CODUTENTE);
SET SOMMA= NEW.COSTOAZIONE*NEW.QTAAZIONE;
SET BUD=BUD-SOMMA;
IF (BUD<0)
raise_application_error (6002, 'budget exceeded');
ELSE
UPDATE UTENTE
WHERE CODUTENTE=NEW.CODUTENTE
SET BUDGET=BUD;
END IF;
END;
delimiter ;
This is my database structure.
Utente_Table
UtenteHaAzione_Table
Unfortunately i used to write trigger in Oracle Databases, so i'm sure that i'm missing something!
Thanks for your help
2 things -
First after the end you need the delim something as
END; |
delimiter ;
Next the update query is wrong and should be as
UPDATE UTENTE
SET BUDGET=BUD
WHERE CODUTENTE=NEW.CODUTENTE
;
