我正在尝试使用UNION运算符创建sql视图。我先尝试执行sql，然后将其嵌入到视图中，结果就是成功。但是，当我尝试嵌入创建视图时，它返回了此错误
“错误代码：1064 您的SQL语法有错误;检查与您的MySQL服务器版本对应的手册，以便在'UNION附近使用正确的语法 SELECT p.product_media_id AS media_id，p.product_title AS title，p.product'at the line 8 “
我还保证所有列都具有相同的数据类型。
SQL视图：
CREATE
/*[ALGORITHM = {UNDEFINED | MERGE | TEMPTABLE}]
[DEFINER = { user | CURRENT_USER }]
[SQL SECURITY { DEFINER | INVOKER }]*/
VIEW `mydbname`.`s_views`
AS
(SELECT c.media_id AS media_id,
c.title AS title,
c.title_slug AS slug,
c.content_one AS description,
c.type AS cat
FROM content_content c
WHERE c.type = 'news'
OR c.type='travel_genius'
AND c.media_id IS NOT NULL
AND c.status = 1
UNION
SELECT p.product_media_id AS media_id,
p.product_title AS title,
p.product_title_slug AS slug,
p.product_description AS description,
'product' AS cat
FROM p_views p
WHERE p.product_media_id IS NOT NULL);
