Hello,
Syntax-wise , what's wrong with the following query :
-- Trigger DDL Statements DELIMITER $$
USE mydb
$$
DROP TRIGGER IF EXISTS annual_scenario;
CREATE TRIGGER annual_scenario
AFTER INSERT ON quote FOR EACH ROW
BEGIN
SET @annual_date = (SELECT NEW.date - INTERVAL 1 YEAR);
SET @annual = (SELECT COUNT(DISTINCT Q.date)
FROM quote Q, instrument I
WHERE Q.date = I.date
AND Q.ticker = I.date
AND Q.market = I.date
AND I.type != 'bank'
AND Q.date = @annual_date
AND Q.ticker = NEW.ticker
AND Q.market = NEW.market
);
SET @annual_close = (SELECT Q.close
FROM quote Q
WHERE Q.ticker = NEW.ticker
AND Q.date = @annual_date
AND Q.market = NEW.market
);
SET @ratio = (NEW.close / @annual_close);
IF @annual = 1 THEN
INSERT INTO
scenario(period,ticker,date_1,date_2,close_1,close_2,ratio)
VALUES('annual',NEW.ticker,NEW.date,@annual_date,NEW.close,@annual_close,@ratio);
ENDIF
END $$
DELIMITER ;
It outputs the following error :
Error Code: 1064

What i am trying to do is checking if annual returns 1 then i would insert a new record into the table scenario with the corresponding values.
