我的MYSQL触发器出错了。我使用了某种形式的语法,但仍然出现语法错误。希望有人可以帮助我。
CREATE TRIGGER after_insert_table_a AFTER INSERT ON table_a
FOR EACH ROW BEGIN
DECLARE colorL VARCHAR(7);
SET linesT = (
SELECT COUNT(id)
FROM lineas
WHERE fk_id = NEW.fk_id
);
IF (linesT = 0) THEN
SET colorL = '#D3D3D3';
ELSE IF (linesT = 1) THEN
SET colorL = (
SELECT l.color
FROM sel_lineas AS tl
INNER JOIN lineas AS l ON l.id = tl.line_id
WHERE tl.fk_id = NEW.fk_id
);
ELSE
SET colorL = '#000000';
END IF;
UPDATE tabla_colors SET colour_l = colorL WHERE id = NEW.fk_id;
END;
我会帮助您提供任何帮助。
以下是错误消息: MySQL说:#1064 - 你的SQL语法有错误;检查与MySQL服务器版本对应的手册,以便在#DEC; DECLARE colorL VARCHAR(7)附近使用正确的语法; SET linesT =(SELECT COUNT' at line 1
