当我在我的功能中没有EventReceivers时,项目构建和部署,并在我这样做时失败.我不完全确定FileNotFoundException指的是哪个文件

视觉工作室给出错误

Error   1   Error occurred in deployment step 'Activate Features': Failed to load receiver assembly "Decisions.Features, Version=1.0.0.0, Culture=neutral, PublicKeyToken=8d09acb153961cfd" for feature "Decisions.Features_DeployDecisionCommittee" (ID: 779492d8-f053-45ce-8340-5fa6d7f87a90).: System.IO.FileNotFoundException: Could not load file or assembly 'Decisions.Features, Version=1.0.0.0, Culture=neutral, PublicKeyToken=8d09acb153961cfd' or one of its dependencies.

让我说我有这样的表变量声明...

DECLARE @LocalTable TABLE
(
    IdField NVARCHAR(MAX),
    NameField NVARCHAR(MAX)
)

我这样填充它......

INSERT INTO @LocalTable
SELECT
    IdColumn,
    NameColumn
FROM SourceTable

NameColumn在源表中可能有重复的值,因此NameField在本地表中将具有相同的重复值.

让我们说我想将本地表插入到目标表中,就像这样......

INSERT INTO TargetTable (NewIdColumn, NewNameColumn)
    SELECT
        IdField,
        NameField
    FROM 
        @LocalTable

但是:NewNameColumnin TargetTable有一个UNIQUE约束,因此重复会导致异常.

我想应用这个例子,

ROW_NUMBER() OVER(PARTITION BY NameField ORDER BY NameField)

这样NameField附加/后缀有表示其重复的数字.

我有这个工作示例可以选择正确的附加值,但我无法在这样的更新语句中使用它:

UPDATE localtable 
SET NameField = AppendedNameField 
FROM @LocalTable AS localtable

SELECT 
    CONCAT(Ref.NameField, ROW_NUMBER() OVER (PARTITION BY Ref.NameField 
                                             ORDER BY Source.IdField)), *
FROM 
    @LocalTable AS Source
INNER JOIN …
