Question

下面的T-SQL语句导致我的一个SSIS打包在执行结束时“挂起”。由于没有错误消息或反馈，因为一些看不见的问题，软件包根本无法完成运行。想到的两件事是A）我想要推送的azure数据库不想给我更新/删除权限B）我的T-SQL语法有问题。

我将假设它的B因为10次中有9次可能是我的错误，而不是系统错误。这个陈述中有什么可能导致这个循环吗？

--UPDATE
BEGIN
  UPDATE
    REPORTING
  SET
    REPORTING.Supplier = dbo.SupplierQuality_ASL_TEMP.Supplier,
    REPORTING.Level = dbo.SupplierQuality_ASL_TEMP.Level,
    REPORTING.Status = dbo.SupplierQuality_ASL_TEMP.Status,
    REPORTING.[Core Competency Service Provided] = dbo.SupplierQuality_ASL_TEMP.[Core Competency Service Provided],
    REPORTING.Location = dbo.SupplierQuality_ASL_TEMP.Location,
    REPORTING.[Outsourced Process] = dbo.SupplierQuality_ASL_TEMP.[Outsourced Process],
    REPORTING.Contact = dbo.SupplierQuality_ASL_TEMP.Contact,
    REPORTING.Phone = dbo.SupplierQuality_ASL_TEMP.Phone,
    REPORTING.Email = dbo.SupplierQuality_ASL_TEMP.Email
  FROM
    [AZURE_REPORTING].[Reporting_Warehouse].[dbo].[SupplierQuality_ASL] as REPORTING
    INNER JOIN dbo.SupplierQuality_ASL_TEMP
      ON REPORTING.SubtaskID = dbo.SupplierQuality_ASL_TEMP.SubtaskID
  WHERE
    REPORTING.SubtaskID = dbo.SupplierQuality_ASL_TEMP.SubtaskID
    AND REPORTING.SubtaskID IS NOT NULL AND dbo.SupplierQuality_ASL_TEMP.SubtaskID IS NOT NULL
END
--DELETE
BEGIN
  DELETE REPORTING
  FROM [AZURE_REPORTING].[Reporting_Warehouse].[dbo].[SupplierQuality_ASL] as REPORTING
  WHERE
    NOT EXISTS
    (
      SELECT *
      FROM dbo.SupplierQuality_ASL_TEMP
      WHERE REPORTING.SubtaskID = dbo.SupplierQuality_ASL_TEMP.SubtaskID
    )
END

不是最终答案，但会显示锁定。尝试：

BEGIN
  DELETE top(10) REPORTING
  FROM [AZURE_REPORTING].[Reporting_Warehouse].[dbo].[SupplierQuality_ASL] as REPORTING
  WHERE NOT EXISTS ( SELECT 1
                     FROM dbo.SupplierQuality_ASL_TEMP as TEMP
                     WHERE REPORTING.SubtaskID = TEMP.SubtaskID
                   )
END

T-SQL语法导致循环？
