SQL Server附加查询

Question

我有以下(不工作)查询:

insert into [MyDB].[dbo].[Reports_StepsStat]  
    (ActivityID,TaskID,StepIndex,StepStatus,TimeSpanInSeconds,Score)
VALUES (
  SELECT
    tasks.ActivityID as ActivityID,
    tasks.ID as TaskID,
    [StepIndex]=item.value('(StepIndex)[1]', 'NVARCHAR(MAX)'),
    [StepStatus]=item.value('(Status)[1]', 'NVARCHAR(MAX)'),
    [TimeSpanInSeconds] = DATEDIFF(MINUTE, item.value('(StartedOn)[1]',    'datetime'),item.value('(FinishedOn)[1]', 'datetime')),
    tasks.Score as Score
  FROM 
    [MyDB].[dbo].[Tasks] as tasks 
  CROSS APPLY 
    [Progress].nodes ('//Progress/Steps/ProgressStep') Progress(item)
)  

内部选择查询(SELECT task.ActivityID..)完美地工作并产生预期的表.

外部insert into部分应该通过名称将内部部分的结果附加到表中Reports_StepsStat.这不起作用.

我尝试并成功地使用SELECT INTO,但显然SELECT INTO只能用于创建一个新表,而不是附加到现有表,这是我需要的.

我得到的错误是:

消息156,级别15,状态1,行6
关键字"SELECT"附近的语法不正确.
消息102,级别15,状态1,行14
'''附近的语法不正确.

我认为VALUES (在您的查询中不需要.

 insert into [MyDB].[dbo].[Reports_StepsStat]  
 (ActivityID,TaskID,StepIndex,StepStatus,TimeSpanInSeconds,Score)
 SELECT
  tasks.ActivityID as ActivityID,
  tasks.ID as TaskID,
  [StepIndex]=item.value('(StepIndex)[1]', 'NVARCHAR(MAX)'),
  [StepStatus]=item.value('(Status)[1]', 'NVARCHAR(MAX)'),
  [TimeSpanInSeconds]=DATEDIFF(MINUTE,item.value('(StartedOn)[1]', 'datetime'),
  item.value('(FinishedOn)[1]', 'datetime')),
  tasks.Score as Score
 FROM [MyDB].[dbo].[Tasks] as tasks 
     CROSS APPLY [Progress].nodes ('//Progress/Steps/ProgressStep') Progress(item)
