我有这个查询： 

SELECT `manufacturers`.*, `languages`.*, COUNT(`products`.`id`) AS productcount
FROM (`manufacturers`)
WHERE `manufacturers`.`flushed` = `0`
JOIN `languages` ON `manufacturers`.`lang` = `languages`.`id`
LEFT OUTER JOIN `products` ON 
`products`.`manuf` =  `manufacturers`.`mid`
GROUP BY manufacturers.id
ORDER BY `languages`.`id` asc, `manufacturers`.`mid` asc;

如果没有 WHERE 行，一切正常，但有了它，我的脸上就会出现错误 1064（语法错误）。我想这与查询中 WHERE 行的实际位置有关，所以我试图移动它，但没有任何运气。

我能做些什么？

where 连接之后，group by 之前（连接被认为是from子句的一部分）

检查这个：

SELECT `manufacturers`.*, `languages`.*, COUNT(`products`.`id`) AS productcount
FROM (`manufacturers`)
JOIN `languages` ON `manufacturers`.`lang` = `languages`.`id`
LEFT OUTER JOIN `products` ON 
`products`.`manuf` =  `manufacturers`.`mid`
WHERE `manufacturers`.`flushed` = `0             -- where comes after joins 
GROUP BY manufacturers.id
ORDER BY `languages`.`id` asc, `manufacturers`.`mid` asc;
