关键字"table"附近的语法不正确

Question

我收到此错误.我正在做的是尝试从一个表和一个数据库中获取数据并将其放入另一个数据库和表中.表格并不完全相同.我正在使用FETCH游标,因此我从db1表中获取第一行,然后将每个列值放入声明的变量中.然后我将insert语句运行到db2表中并获取下一个值.这一切似乎都正常工作,因为它运行良好,但最后我得到这个错误,

关键字"table"附近的语法不正确.

整个事务语句在TRY/CATCH中,在CATCH块中具有错误处理表达式.除此之外我不知道是什么原因引起的.请帮忙.

这是代码

  BEGIN

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

  BEGIN TRY
    BEGIN TRANSACTION

    --TURN OFF ITENDITY COLUMNS
    SET IDENTITY_INSERT [DB].[dbo].[TEST] ON

    --TURN OFF ALL CONSTRAINTS 
    ALTER TABLE [DB].[dbo].[TEST] NOCHECK CONSTRAINT ALL

    -- Insert statements for procedure here
    DECLARE  @ID int,
             @DT datetime,
             @PID varchar(10),
             @AREA varchar(20)


    DECLARE FETCH_TEST CURSOR FOR

    SELECT [ID]
      ,[Date]
      ,[PID]
      ,[Area]

    FROM [OLDDB].[dbo].[TEST] as db1

    OPEN FETCH_TEST;

    FETCH NEXT FROM FETCH_TEST INTO @ID, 
             @DT,
             @PID,
             @AREA


    WHILE @@FETCH_STATUS = 0
      BEGIN

             --INSTER VALUES INTO THE TABLE
            INSERT INTO [DB].[dbo].[TEST]
                       ([ID]
                       ,[DT]

首先,在您的代码中永远不会声明@TRAIN_ID

必须声明标量变量"@TRAIN_ID".

第二是你不需要光标,而是基于SET的操作有什么问题呢？它会表现得更好!! 用这个替换光标部分

INSERT INTO [DB].[dbo].[TEST]
                       ([ID]
                       ,[DT]
                       ,[PID]
                       ,[AREA])

SELECT [ID]
      ,[Date]
      ,[PID]
      ,[Area]
FROM [OLDDB].[dbo].[TEST] as db1

你还有一个额外的逗号

 FETCH NEXT FROM FETCH_TEST INTO 
             @ID, 
             @DT,
             @PID,
             @AREA,

应该

 FETCH NEXT FROM FETCH_TEST INTO 
             @ID, 
             @DT,
             @PID,
             @AREA

但就像我说的那样你不需要光标
