從* to_tsvector中選擇* - 連接表

Question

我想設置to_tsvector語言（例如：'French'），以便在渲染FTS矢量時使用正確的字典。

表格消息有一個locale_id列，該列在locales表中。然後，我需要將locales表加入locale_id的languages表中以獲取實際的語言名稱。但我發現了一個模糊的;錯誤：

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); 

ERROR: syntax error at or near ";" LINE 1: ....id)

inner join languages as t3 on (t2.language_id = t3.id);

Answer 1

新代碼：

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); 

原修復：

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);
