各位大家好，请原谅我的英语不好我试图解决我的问题超过4天了：每个触发器都运行良好但是当我将它们组合起来时会出现错误： the subquery returns more than 1 value。

我试图遵循本网站和其他人的所有提示，但我无法使其有效。有关表格包括：PIECES，COMPOSITIONSGAMMES，术语和情况。我希望触发器做的是：

当用户在＆＃34; SITUATIONS＆＃34;上插入新行时如果＆＃39; nomstrategie＆＃39; =＆＃34; DST＆＃34; （它是一个策略的名称，但这个细节并不重要，我的意思是对于那些会帮助我的人），我需要插入其他行以相同的参考（参考），相同的策略（nomstrategie）。只有＆＃39; ancienposte＆＃39;和＆＃39; nouveauposte＆＃39;必须改变。事实上，第一个价值必须是全部的Numeroposte＆＃39;从表格＆＃34; Compositionsgammes＆＃34;。第二个值必须是＆＃39; ???＆＃39;
我需要，当我插入一个新行并且＆＃39; nomstrategie＆＃39; =＆＃39; DST＆＃39;时，其他行将插入所有＆＃39; piecesfilles＆＃39;在表格＆＃34; Nomenclatures＆＃34; 参考文献＆＃39;参考文献＆＃39;在用户插入的行中。而且在“ancienposte＆＃39;”中，应该有“numeroposte＆＃39;在表格＆＃34; compositiongammes＆＃34;。
我需要，当用户插入新行并且“删除”时，要插入另一行，例如：

插入行：参考A ancienposte：P01 Nouveauposte：P02 Nomstrategie：Delestage ............

要插入的行：Ref A ancienposte：P02 Nouveauposte：NULL Nomstrategie：Delestage ............
我需要，对于表格中的每一行＆＃34;情境＆＃34;，计算一个名为＆＃39; charge＆＃39;在表中情况charge =（TS / Taillelot）+ Tu

以下是我已经完成的触发器：

create trigger [dbo].[ALLDST]
ON [dbo].[SITUATIONS]
AFTER INSERT /*pas d'update*/
as 
        begin
        set nocount on
            insert into SITUATIONS(ReferencePiece,nomstrategie,AncienPoste,nouveauposte,DateStrategie)
            select distinct i.referencepiece, i.nomstrategie,COMPOSITIONSGAMMES.NumeroPoste,'???',i.DateStrategie

            from inserted i, PIECES, compositionsgammes, SITUATIONS s
            where i.ReferencePiece is not null 
            and i.NomStrategie='DST' 
            and i.ReferencePiece=pieces.ReferencePiece and pieces.CodeGamme=COMPOSITIONSGAMMES.CodeGamme 
            and i.AncienPoste<>COMPOSITIONSGAMMES.NumeroPoste
            and i.DateStrategie=s.DateStrategie

            end



create trigger [dbo].[Calcul_Charge]
on [charges].[dbo].[SITUATIONS]
after insert 
as
begin


update situations

set charge= (select (cg.TS/pieces.TailleLot)+cg.tu from situations s
inner join COMPOSITIONSGAMMES cg on cg.NumeroPoste=SITUATIONS.AncienPoste
inner join pieces on SITUATIONS.ReferencePiece=pieces.ReferencePiece 
inner join inserted i on s.DateStrategie=i.DateStrategie
where cg.CodeGamme=pieces.CodeGamme and NumeroPoste=situations.AncienPoste
)   

end


create trigger [dbo].[Duplicate_SITUATIONS]
ON [dbo].[SITUATIONS]
AFTER INSERT
as 
        begin
        set nocount on
        declare @ref varchar(50)
        declare @strategie varchar(50)
        declare @ancienposte varchar(50)
        declare @datestrategie date
        declare @pourcentage decimal(18,3)
        declare @coeff decimal(18,3)
        declare @charge decimal(18,3)
        /*while (select referencepiece from situations where ReferencePiece)  is not null*/
            select @ref=referencepiece, @strategie=nomstrategie,@ancienposte=NouveauPoste,
            @datestrategie=datestrategie, @pourcentage=PourcentageStrategie,@coeff=coeffameliorationposte,@charge=charge
            from inserted,POSTESDECHARGE 
            where ReferencePiece is not null
            and POSTESDECHARGE.NumeroPoste = inserted.AncienPoste
            if @strategie = 'delestage' and @ancienposte is not null
            /*if GETDATE()>= (select datestrategie from SITUATIONS)*/
            begin
            insert into SITUATIONS(ReferencePiece, nomstrategie,AncienPoste,DateStrategie,
            StatutStrategie,DateModification,PourcentageStrategie,charge)
            values
            (@ref, @strategie, @ancienposte, @datestrategie,1,getdate(),@pourcentage,@charge*@coeff)
            end
            end

我最熟悉T-SQL（MS SQL），不确定这是否适用于您的情况..但我通常使用子查询避免更新并重写您的更新：

update situations

set charge= (select (cg.TS/pieces.TailleLot)+cg.tu from situations s
inner join COMPOSITIONSGAMMES cg on cg.NumeroPoste=SITUATIONS.AncienPoste
inner join pieces on SITUATIONS.ReferencePiece=pieces.ReferencePiece 
inner join inserted i on s.DateStrategie=i.DateStrategie
where cg.CodeGamme=pieces.CodeGamme and NumeroPoste=situations.AncienPoste
)

如下

update s set 
    charge= (cg.TS/pieces.TailleLot)+cg.tu
from situations s
    inner join COMPOSITIONSGAMMES cg on cg.NumeroPoste=SITUATIONS.AncienPoste
    inner join pieces on SITUATIONS.ReferencePiece=pieces.ReferencePiece 
    inner join inserted i on s.DateStrategie=i.DateStrategie
where cg.CodeGamme=pieces.CodeGamme and NumeroPoste=situations.AncienPoste

四个触发器：它不起作用
