당신이 날이 문제를 해결하는 데 도움시겠습니까 말한다 오류가 표시습니까? 나는 그것을 더 쉽게 이해할 수 있도록 예제를 제공해 주셔서 감사하게 생각합니다.

Answer 1

달성 할 의미가있는 WHERE 절은 무엇입니까? 이 뜻이야?

WHERE 
     Stu_info.Id_num = Development_fee.Id_num 
    AND Stu_info.Id_num = Tuition_fee.Id_num 
    AND Stu_info.Id_num = Registration_fee.Id_num 
    AND Stu_info.Id_num = Form_fill_up_fee.Id_num 
    AND Stu_info.Id_num = Examination_fee.Id_num 
    AND Stu_info.Id_num = monthly_instal.Id_num 

또한 FROM tableA, TableB, TableC은 매우 오래된 스타일 표기법입니다. AND 또는 OR 아닌 쉼표

Answer 2

분리하여 절) 및 표 별칭을 사용하여 검색어를 더 쉽게 이해하고 읽기 쉽게 만들 수 있습니다.

SELECT 
    stu.Id_num, stu.Stu_name, 
    df.Dvf, 
    tf.Acy, tf.Tui_fee, 
    rf.Reg_fee, 
    ffuf.Acy, ffuf.FFF, 
    ef.E_typ, ef.Exm_fee, 
    mi.Instm, mi.Paid  
FROM 
    [SUIMT].[dbo].[Stu_info] stu 
INNER JOIN 
    [SUIMT].[dbo].[Development_fee] df ON df.Id_num = stu.id_num 
INNER JOIN 
    [SUIMT].[dbo].[Tuition_fee] tf ON tf.Id_num = stu.id_num 
INNER JOIN 
    [SUIMT].[dbo].[Registration_fee] rf ON rf.Id_num = stu.id_num 
INNER JOIN 
    [SUIMT].[dbo].[Form_fill_up_fee] ffuf ON ffuf.Id_num = stu.id_num 
INNER JOIN 
    [SUIMT].[dbo].[Examination_fee] ef ON ef.Id_num = stu.id_num 
INNER JOIN 
    [SUIMT].[dbo].[monthly_instal] mi ON mi.Id_Num = stu.Id_num 

이렇게하면 못생긴 WHERE 절도 필요하지 않습니다 .....

Answer 3
