Question

我需要创建

的程序

将源表中的数据插入或更新到target1表
将数据插入target2表并将获得插入的ID 来自target1，target2 tables
将它们插入目标表3
将target1.ID插入target4表

源表是一个临时表，我使用批量复制将大数据插入到该表中，然后将数据移动到目标表以获得性能。

MSPCompanies - insert or update по признаку INN
MSPDownloads insert
MSPAccepted insert MSPCompanies.ID и MSPDownloads.ID
MSPAcceptedNow insert MSPCompanies.ID

在MSPCompanies中插入或更新我使用MERGE

BEGIN
 BEGIN TRY
  BEGIN TRANSACTION
 -- SET NOCOUNT ON added to prevent extra result sets from
 -- interfering with SELECT statements.
 SET NOCOUNT ON;

    -- Insert statements for procedure here
 MERGE INTO [MSPCompanies] AS [Target]
USING [MSPTempTable] AS [Source]
 ON Target.INN = Source.INN
WHEN MATCHED THEN
UPDATE SET 
 Target.Name = Source.Name,
 Target.ShortName = Source.ShortName,
 Target.FIO = Source.FIO,
 Target.SubjectType = Source.SubjectType,
 Target.SubjectCategory = Source.SubjectCategory,
 @MSPCompaniesId = Target.MSP_Companies_ID

WHEN NOT MATCHED THEN
INSERT 
 (INN, Name, ShortName, FIO, SubjectType, SubjectCategory) 
VALUES 
 (Source.INN, Source.Name, Source.ShortName, Source.FIO, Source.SubjectType, Source.SubjectCategory);

IF @MSPCompaniesId IS NULL
BEGIN
    SET @MSPCompaniesId = CAST(SCOPE_IDENTITY() as [int]);
END
SELECT @MSPCompaniesId
--BEGIN
INSERT INTO dbo.MSPAcceptedNow
(MSP_Company_ID)
VALUES(@MSPCompaniesId)

但看起来似乎无法使用其他三个表进行其他操作，并尝试使用insert-update进行操作，但无论如何都无法做到。

BEGIN TRANSACTION MoveDataFromMSPTempTableT; 
UPDATE t
    SET 
  Name = s.Name,
  ShortName = s.ShortName,
  FIO = s.FIO,
  SubjectType = s.SubjectType,
  SubjectCategory = s.SubjectCategory
    FROM MSPCompanies t
        JOIN MSPTempTable s
        ON s.INN = t.INN;

INSERT INTO MSPCompanies
        SELECT s.INN,
               s.Name,
      s.ShortName,
      s.FIO,
      s.SubjectType,
      s.SubjectCategory
            FROM MSPTempTable s
                LEFT JOIN MSPCompanies t
                ON s.INN = t.INN
            WHERE t.INN IS NULL;

COMMIT TRANSACTION MoveDataFromMSPTempTableT;

谢谢。

您无法使用变量跟踪所有更改，但可以使用OUTPUT跟踪所有更改。

<style>
.txtArea{
    overflow:auto;
    height:100px;
    width:500px;
    -moz-transform: scale(0.9);
    -webkit-transform: scale(0.9);
    -o-transform: scale(0.9);
    transform: scale(0.9);
}
</style>
<textarea class="txtArea">
</textarea>
