Question

我在SQL Server 2008数据库中有一个具有datetime2字段的视图。我需要能够通过链接的SQL Server 2005从该视图进行查询。当我打开我的光标并获取记录时，我得到一个“从字符串转换日期时转换失败”。错误。如何使光标正确转换datetime2？

这是我的查询失败

DECLARE @time DateTime

DECLARE db_cursor CURSOR FOR
SELECT [DateTime] FROM [LINKEDSERVER].[DATABASENAME].[dbo].[ViewName] 
  WHERE Name = 'blah'

OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @time

WHILE @@FETCH_STATUS = 0
BEGIN
  Print @time
  FETCH NEXT FROM db_cursor INTO @time
END

CLOSE db_cursor
DEALLOCATE db_cursor

有什么想法吗？

尝试按以下方式声明游标：

DECLARE db_cursor CURSOR FOR
SELECT cast([DateTime] as DateTime) FROM [LINKEDSERVER].[DATABASENAME].[dbo].[ViewName] 
  WHERE Name = 'blah'

<强> BUT

如果来自DATETIME2字段的远程值超出允许的DateTime类型，请尝试以下

DECLARE @time NVARCHAR(100)

DECLARE db_cursor CURSOR FOR
SELECT CAST([DateTime] as NVArCHAR(100)) FROM [LINKEDSERVER].[DATABASENAME].[dbo].[ViewName] 
  WHERE Name = 'blah'

OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @time

WHILE @@FETCH_STATUS = 0
BEGIN
  Print @time
  FETCH NEXT FROM db_cursor INTO @time
END

CLOSE db_cursor
DEALLOCATE db_cursor

由于datetime2，SQL转换错误
