MySql trigger Syntax - mysql

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

mysql CREATE trigger not working, error while creating the trigger

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

Mysql Trigger creation query - Syntax error

I am getting an error in my mySql query when i execute my create trigger query in mysql using phpmyadmin which is provided below.
Error:
Error Message :
#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 5
MySql Query:
CREATE TRIGGER Trigger_INSERT_club_app_member_contact_info After INSERT ON club_app_member_contact_info
FOR EACH ROW
BEGIN
INSERT INTO club_app_events_list(type_id,event_title,event_description,event_date,event_time,event_venue)
values(1,CONCAT('Happy Birthday ',NEW.title,NEW.name),NEW.mobile_no,NEW.dob,'8.30AM','');
IF NEW.ismarried == 'Yes' THEN
INSERT INTO club_app_events_list(type_id,event_title,event_description,event_date,event_time,event_venue)
values(1,CONCAT('Happy Birthday ',NEW.title_for_spouse,NEW.nameOf_spouse,'Spouse of (',NEW.title,NEW.name,')'),NEW.spouse_mobileNo,NEW.spouse_dob,'8.30AM','');
INSERT INTO club_app_events_list(type_id,event_title,event_description,event_date,event_time,event_venue)

END IF
END
I don't know what's wrong with my query.Can anyone help me to find a solution.

Few thing i noticed IF NEW.ismarried == 'Yes' THEN it should IF NEW.ismarried = 'Yes' THEN BEGIN and END IF should end with semicolon ; although BEGIN end enclose END;
But since i am trying to execute this query using phpmyadmin I have to remove Delimiter from the bottom text box of phpmyadmin.
But note that this is only phpmyadmin analysis warnings not a mysql server response.

Adding Triggers in phpmyadmin

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;

Error on SQL query right syntax to use near '' at line 4

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.

MySQL CREATE TRIGGER, Syntax Error. What I'm doing wrong?

DELIMITER ||
CREATE TRIGGER `monthly_insert` BEFORE INSERT ON `history_monthly`
FOR EACH ROW
BEGIN
NEW.`uid` = CONCAT(OLD.`year`, OLD.`month`, OLD.`charactersId`);
END;
||
DELIMITER ;
And it returns an error:
#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 '.`uid` = CONCAT(OLD.`year`, OLD.`month`, OLD.`charactersId`);
END' at line 4
It's my first time with triggers and I was doing my best to try to find soultion but I failed ;<

You need to add the word SET in this line:
SET NEW.`uid` = CONCAT(OLD.`year`, OLD.`month`, OLD.`charactersId`);
Also, as the commenter pointed out, there is no OLD value in a BEFORE INSERT trigger.
