My teacher sent me this code, we are doing mysql, last time she sent oraclesql code, so this might be oraclesql:
CREATE TRIGGER Kontrola
ON DATABASE
FOR DROP_TABLE, ALTER_TABLE
AS PRINT "Brisanje i izmena nad objektima nije dozvoljena!"
ROLLBACK
And it says:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'ON IZVRSIOCI
AFTER INSERT
AS BEGIN
PRINT 'Novi zapis u tabeli'
END' at line 2

I am new to MySQL and am trying to write a basic procedure that deletes all the email addresses that are not in the correct format. In this case, a invalid email address is anything that does not have an # symbol anywhere in the email.
But when I try to execute the query, it gives me the error #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'END' at line 4. This is the query I have so far.
Create Procedure DeleteInvalidEmail ()
Begin
DELETE FROM mockdata__2_ WHERE email NOT REGEXP '#+'
END
I was using the MySQL documentation example so I'm really not sure whats wrong
While I'm attempting to make a mySQL function to find a player by their ID, I'm getting repeated syntax errors no matter what I fix, and I'm unclear as to what I'm doing wrong. I've tried reading through other source materials on here to help, but anything I've tried hasn't been successful.
I've tried reading through Error while using lookup function and "MySQL syntax error" while creating a function which I don't think really pertain to my syntax errors, though I'm really new to coding functions in mysql, so I'm unsure what my problems even are.
delimiter //
DROP FUNCTION IF EXISTS findRaider//
CREATE FUNCTION findRaider(ID INT) RETURNS VARCHAR(20)
BEGIN
DECLARE NAME_FOUND VARCHAR DEFAULT " ";
SELECT name INTO NAME_FOUND FROM players WHERE player_id=ID;
RETURN NAME_FOUND;
END;//
delimiter ;
Expected: SELECT findRaider(1); RETURNS "Seranul"
Actual:
ERROR 1327(42000) Undeclared variable: NAME_FOUND
ERROR 1064(42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'RETURN NAME_FOUND' at line 1

I want to add a trigger in my database in phpmyadmin to rollback an insertion into the table if a particular attribute is greater than 100.
Here is my code that I wrote in the window for define in the "Add Trigger" window:
BEGIN
ROLLBACK IF NEW.max_allowed > 100
END;
I am getting this error:
MySQL said: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'IF NEW.max_allowed > 100 END' at line 2
Can someone please suggest what I'm missing?
ROLLBACK can't be used together with IF in the same statement.
Check the documentation.
I suggest this code for your trigger:
BEGIN
IF NEW.max_allowed > 100 THEN
ROLLBACK;
END IF;
END;
i'm trying to create a trigger on my database but i'm getting this error "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 4 " but i can't understand why. This is the query:
CREATE TRIGGER cancella_associativa AFTER DELETE ON libro
FOR EACH ROW
BEGIN
DELETE FROM annuncio_autore
WHERE libro.`idLibro` = annuncio_autore.`idAnnuncio`;
END
Using phpMyAdmin, thanks in advance.
The ; after the line that contains WHERE ends your (incomplete) CREATE TRIGGER query. You need to change the delimiter:
delimiter //
CREATE TRIGGER ... //
delimiter ;
For more information see MySQL manual.
Could someone please tell me what's wrong with my Mysql-syntax in the following trigger?
CREATE TRIGGER hQual AFTER INSERT ON Musikstück FOR EACH ROW BEGIN
IF(length(NEW.bitrate)=4) THEN
IF ((CONVERT(substr(NEW.bitrate,2,3),SIGNED INTEGER))<320) THEN
UPDATE Album SET High_Quality = 0 WHERE Album.Albumname=NEW.Albumname;
END IF
ELSEIF((CONVERT(NEW.bitrate,SIGNED INTEGER))<320) THEN
UPDATE Album SET High_Quality = 0 WHERE Album.Albumname=NEW.Albumname;
END IF
END
It's too late over here, I'm tired and I don't see it :) MySql is just saying:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 4
