Answer 1

试试这个

select (1- (s1 + s2 + s3) / (s4 + s5 + s6))*100,startdate
from
(   select sum(v1) as s1 ,sum(v2) as s2,sum(v3) as s3,sum(v4) as s4,sum(v5) as s5,sum(v6) as s6,startdate 
    from
    (   select avg(case when indicateur like '%Vmgw%' and compteur = 'pmNrOfAal2TermsRej' then valeur else null end) as v1,
        avg(case when indicateur like '%Vmgw%' and compteur = 'pmNrOfIpTermsRej' then valeur else null end) as v2,
        avg(case when indicateur like '%TdmTermGrp%' and compteur = 'pmNrOfTdmTermsRej' then valeur else null end) as v3,
        avg(case when indicateur like '%Vmgw%' and compteur = 'pmNrOfAal2TermsReq' then valeur else null end) as v4,
        avg(case when indicateur like '%Vmgw%' and compteur = 'pmNrOfIpTermsReq' then valeur else null end) as v5,
        avg(case when indicateur like '%TdmTermGrp%' and compteur = 'pmNrOfTdmTermsReq' then valeur else null end) as v6,
        startdate
        from MGW1
        group by startdate
    ) xDerived1 --  NEED AN ALIAS HERE
    group by startdate
) xDerived2 --  NEED AN ALIAS HERE

请注意我隐藏的两个派生表名（xDerived1和xDerived2）。它超过了错误代码1248

Answer 2

我在第11行遇到语法错误：

选择（1-（s1 + s2 + s3）/（s4 + s5 + s6））* 100作为succ_rate，startdate as Time 从（选择sum（v1）为s1，sum（v2）为s2，sum（v3）为s3，sum（v4）为s4，sum（v5）为s5，sum（v6）为s6，startdate 从（选择avg（如'％Vmgw％'和compteur ='pmNrOfAal2TermsRej'表示的情况，然后是valeur else null结束时的情况）为v1， avg（如'vmw％'和compteur ='pmNrOfIpTermsRej'那样表示为valeur else null结束时的情况）为v2， avg（在指示'％TdmTermGrp％'和compteur ='pmNrOfTdmTermsRej'然后valeur else null结束时的情况）为v3， avg（如'v V vw''和compteur ='pmNrOfAal2TermsReq'然后是valeur else null结束时的情况）为v4， avg（如'v V vw''和compteur ='pmNrOfIpTermsReq'然后valeur else null结束时的情况）为v5， avg（在指示'％TdmTermGrp％'和compteur ='pmNrOfTdmTermsReq'然后valeur else null结束时的情况）为v6，开始日期来自SUBSTR（date_format（startdate，'AAAA-％m-JJ HH：％m：％s'），1,10）的数据，如$ P {date_debut}和MGW，如$ P {par_mgw} group by startdate，MGW）

＃1248 - 每个派生表必须有自己的别名吗？ Error_mysql phpmyadmin
