我有个问题。我正在使用游标。每次获取最后的记录并打印其数据后，光标都会打印一条附加行。要理解我的意思，请考虑以下示例示例：我只想打印有关10个客户的信息。

USE Northwind
GO

DECLARE myCursor CURSOR 
FOR SELECT TOP(10) ContactName FROM Customers
DECLARE @RowNo int,@ContactName nvarchar(30)
SET @RowNo=1
OPEN myCursor
FETCH NEXT FROM myCursor INTO @ContactName
PRINT  LEFT(CAST(@rowNo as varchar) + '      ',6)+'  '+ @ContactName
SET @RowNo=@RowNo+1
SET @ContactName=''
WHILE @@FETCH_STATUS=0
  BEGIN
        FETCH NEXT FROM myCursor INTO @ContactName
        PRINT + LEFT(CAST(@rowNo as varchar) + '      ',6)+'  '+ @ContactName
        SET @RowNo=@RowNo+1
        SET @ContactName=''
  END
CLOSE myCursor
DEALLOCATE myCursor

现在看一下输出：
