我寫這樣的代碼：如何解決「錯誤代碼是1054'unknown列

select dp.c201_user_id 
     ,dp.c201_name 
     ,ct.c202_week_id 
     ,ct.c203_start_timing 
     ,edu.college_ID 
     ,edu.complete_year 
from physidesk.doctor_personal dp 
join physidesk.clinic_timing ct on c201_USER_ID =ct.C101_USER_ID 
join physidesk.t207_education edu on ct.C101_USER_ID=edu.C101_USER_ID;

可以說任何的ocurring錯誤

哪裏是表't207_education'？ – Jens

'ct.C101_USER_ID'必須是'ct.C201_USER_ID' – Jens

c201_USER_ID = ct.C101_USER_ID必須是dp。 c201_USER_ID = ct.C201_USER_ID – nacho

嘗試此查詢 -

select dp.c201_user_id 
     ,dp.c201_name 
     ,ct.c202_week_id 
     ,ct.c203_start_timing 
     ,edu.college_ID 
     ,edu.complete_year 
from physidesk.doctor_personal dp 
join physidesk.clinic_timing ct on dp.c201_USER_ID =ct.C101_USER_ID 
join physidesk.t207_education edu on ct.C101_USER_ID=edu.C101_USER_ID;

又是錯誤 –

你得到了什麼錯誤。請用代碼發佈完整的錯誤。 –

假設你的edudation表是t207_education，下面的查詢應該可以工作。在第一次加入期間，您必須擁有dp.c201_user_id而不是c201_user_id。

select dp.c201_user_id 
    ,dp.c201_name 
    ,ct.c202_week_id 
    ,ct.c203_start_timing 
    ,edu.college_ID 
    ,edu.complete_year 
    from physidesk.doctor_personal dp 
    join physidesk.clinic_timing ct on dp.c201_user_id =ct.c201_user_id 
    join physidesk.t207_education edu on ct.c201_user_id=edu.c201_user_id;
