聲明不funtion使用PostgreSQL

Question

這是我工作的功能。

這是輸出：

ERROR: invalid type name "CONCAT(translate,'=true') INTO tempo FROM seo_content WHERE name"

即使當我刪除的concat和我只是不停地翻譯，我得到

ERROR: invalid type name "translate INTO tempo FROM seo_content WHERE name"

感謝

試試這個：

CREATE OR REPLACE FUNCTION public.func_leonard_test2(
    IN url text, 
    OUT translation text) 
    RETURNS text AS 
$BODY$ 

DECLARE tempo text; 
BEGIN 

SELECT CONCAT(translate,'=true') INTO tempo FROM seo_content WHERE "name"=url;  

    CASE 

     WHEN tempo = 'location_town' THEN 

      translation := 'A'; 

     ELSE 

      translation := 'B'; 

    END CASE; 

END;$BODY$ language plpgsql;
