Question

我想设置to_tsvector语言（例如：'French'），因此在渲染FTS向量时它会使用正确的字典。

表消息的locale_id列位于locales表中。然后，我需要将locales表加入locale_id上的languages表以获取实际的语言名称。但是我收到了一个含糊不清的;错误：

select * from to_tsvector(t3.language, t1.message) 
inner join message as t1 
inner join locales as t2 on (t1.locale_id = t2.id) 
inner join languages as t3 on (t2.language_id = t3.id);

错误：语法错误在“或”附近第1行：.... id）

内连接语言为t3 on（t2.language_id = t3.id）;

Answer 1

较新的代码：

select to_tsvector(t3.language, t1.message) 
from message as t1 
inner join locales as t2 on (t1.locale_id = t2.id) 
inner join languages as t3 on (t2.language_id = t3.id);

原始修复：

select * from to_tsvector(t3.language, t1.message) 
inner join message as t1 on 1 = 1 /* an ON join criteria is mandatory here even if you are doing an implicit cross join */
inner join locales as t2 on (t1.locale_id = t2.id) 
inner join languages as t3 on (t2.language_id = t3.id);

从to_tsvector中选择* - 连接表格
