Question

我在通过外部应用程序将记录插入数据库时尝试更新记录时遇到了麻烦。

我需要从应用程序中的用户插入的记录从表MinimumStock获取值AERO_LOCATIONSTOCKMIN，其中父级位置和资产类型

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

这就是目的：当用户尝试在Asset表上插入记录（通过外部应用程序）时，触发器必须检查用户是否选择了Asset的位置。如果是，则触发器必须检索所选位置的父位置，并检查是否存在为此AssetType和此父位置定义的库存最小值。

如果完成所有操作，触发器必须将字段UDFText01设置为上表中定义的最小库存。

这是我迄今为止所尝试的内容。触发器正在检查要求，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。

我尝试以多种方式修改UPDATE语句，但所有这些都会引发相同的错误消息。

修改

关注@Sean Lannge的建议我已经编辑了我的触发器以管理多个插件。触发器不再显示错误消息，但更改（插入）不会保存到数据库中。

根据此处的扩展讨论，看看这样的事情是否与你想要做的事情更接近。

if(chmod!=ch){
        chLast=chmod;
        i++;
          if(i==1)
        chFirst=chmod;
    }
