在触发器上更新插入的记录

Question

我在通过外部应用程序将数据插入数据库时​​尝试更新记录时遇到问题。

我需要记录从应用程序的用户被插入取值MinimumStock从表AERO_LOCATIONSTOCKMIN上它们是父位置和资产类型

LOCATIONSTOCKMINID ASSETTYPEID LOCATIONID MINIMUMSTOCK 
    54000000001  54000000043 43200000357  12.00 
    54000000002  54000000043 43200000883  6.00 

这是目的：当用户尝试要在Asset表中插入记录（通过外部应用程序），触发器必须检查用户是否已为该Asset选择位置。如果是这样，触发器必须检索所选位置的父级位置，并检查是否存在为此AssetType定义的库存最小值以及此父级位置。

如果全部满足，则触发器必须将字段UDFText01设置为上表中定义的最小库存。

这是我到目前为止尝试过的。触发器正在检查需求，但在尝试更新并引发以下错误时失败：

The transaction ended in the trigger. The batch has been aborted。

我试图以许多方式修改UPDATE语句，但它们都引发了相同的错误消息。

编辑

继@Sean Lannge的建议我已经编辑了扳机，以管理多个刀片。触发器不再显示错误消息，但更改（插入）未保存到数据库中。

基础上进一步讨论，在这里看到，如果这样的事情是不是有点接近你正在尝试做的。

ALTER TRIGGER [spectwosuite].[TRI_ASSET_STOCKMIN] ON [spectwosuite].[ASSET] FOR INSERT AS 
IF (UPPER(USER) != 'SPECTWOREPLENG') 
BEGIN 

    create table #MyInsertedCopy 
    (
     --whatever columns go here that you want to display for error rows 
     ErrorMessage varchar(50) 
    ) 

    insert #MyInsertedCopy 
    select i.* --use your real columns, not * 
     , 'Please fill the Location for the Asset' as ErrorMessage 
    from inserted i 
    left join Location l on l.LocationID = i.LocationID 
    where l.LocationID IS NULL 

    insert #MyInsertedCopy 
    select i.* --use your real columns, not * 
     , 'The parent location for that Asset doesn''t have minimum stock defined' as ErrorMessage 
    from inserted i 
    left join AERO_LOCATIONSTOCKMIN a on a.AssetTypeID = i.AssetID 
    left join Location l on l.ParentLocationID = i.LocationID 
    where a.AssetTypeID is NULL 

    update a 
    set UDFText01 = MinimumStock 
    FROM INSERTED I 
    INNER JOIN spectwosuite.ASSET T ON T.AssetID = I.AssetID 
    INNER JOIN AERO_LOCATIONSTOCKMIN a on a.AssetTypeID = i.AssetID 
    INNER JOIN Location l on l.ParentLocationID = i.LocationID 

    IF EXISTS(select * from #MyInsertedCopy) 
     --do something to report that there are rows that failed 
     select * from #MyInsertedCopy 
END
