SQL中的语法错误？哪里？

Question

SELECT `bio_community_events`.`id`, 
     `bio_community_events`.`begin_on`, 
     `bio_community_events`.`name` 
    FROM `bio_community_events` 
    JOIN `bio_contacts` 
    ON (`bio_contacts`.`contact_id` = `bio_community_events`.`user_id`) 
    JOIN `bio_community_groups` 
    ON (`bio_community_groups`.`id` = `bio_community_events`.`group_id`) 
WHERE `bio_contacts`.`user_id` = '33' 
WHERE `bio_community_events`.`group_id` = '1' 
LIMIT 10 

UNION ALL 

SELECT `bio_community_events`.`id`, 
     `bio_community_events`.`begin_on`, 
     `bio_community_events`.`name` 
    FROM `bio_community_events` 
    JOIN `bio_contacts` 
    ON (`bio_contacts`.`user_id` = `bio_community_events`.`user_id`) 
    JOIN `bio_community_groups` 
    ON (`bio_community_groups`.`id` = `bio_community_events`.`group_id`) 
WHERE `bio_contacts`.`contact_id` = '33' 
WHERE `bio_community_events`.`group_id` = '1' 
LIMIT 10 

它说：

[错误] 1064 - 你在你的 SQL语法错误;检查手册， 对应于您的MySQL服务器 版本的正确语法使用 'WHERE bio_community_events'附近。 group_id = '1'

我找不到语法错误！

编辑：

我包都变成支架，并添加 “在哪儿”。不工作...仍然是同样的错误。

新建查询：

SELECT `bio_community_events`.`id`, 
`bio_community_events`.`begin_on`, 
`bio_community_events`.`name` 
FROM `bio_community_events` 
JOIN `bio_contacts` 
ON (`bio_contacts`.`contact_id` = `bio_community_events`.`user_id`) 
JOIN `bio_community_groups` 
ON (`bio_community_groups`.`id` = `bio_community_events`.`group_id`) 
WHERE (`bio_contacts`.`user_id` = '33') 
AND WHERE (`bio_community_events`.`group_id` = '1') 
LIMIT 10 

UNION ALL 

SELECT `bio_community_events`.`id`, 
`bio_community_events`.`begin_on`, 
`bio_community_events`.`name` 
FROM `bio_community_events` 
JOIN `bio_contacts` 
ON (`bio_contacts`.`user_id` = `bio_community_events`.`user_id`) 
JOIN `bio_community_groups` 
ON (`bio_community_groups`.`id` = `bio_community_events`.`group_id`) 
WHERE (`bio_contacts`.`contact_id` = '33') 
AND WHERE (`bio_community_events`.`group_id` = '1') 
LIMIT 10

我看着你的榜样。愚蠢的我！谢谢。

Answer 1

您有2 WHERE条款，您需要用AND或OR替换您的第二个WHERE。

编辑：像ypercube指出的，你在UNION条款的子查询中都有错误。

例如：

SELECT `bio_community_events`.`id`, 
    `bio_community_events`.`begin_on`, 
    `bio_community_events`.`name` 
FROM `bio_community_events` 
JOIN `bio_contacts` 
    ON (`bio_contacts`.`user_id` = `bio_community_events`.`user_id`) 
JOIN `bio_community_groups` 
    ON (`bio_community_groups`.`id` = `bio_community_events`.`group_id`) 
WHERE `bio_contacts`.`contact_id` = '33' 
AND `bio_community_events`.`group_id` = '1' 
LIMIT 10 

编辑2：

甲WHERE子句需要一个布尔表达式。每个查询只能有一个WHERE子句。

SELECT syntax

Expression syntax

如果你想连接2倍的表达，你必须使用OR或AND等 你不需要再写WHERE条款。这一切都进入一个WHERE。
