使用 SQL Server 导出向导时日期格式无效

Question

我正在尝试将数据从一个 SQL Server 导出到另一个。我有大约 12 个表，其中 11 个已成功导出，但是在一个表中出现问题，它有 2 列为 DateTime，在导出时我遇到了这个异常：

它成功复制了大约 4025 行，我有大约 21794 行，所以手动查看每一行有点困难，所以我尝试运行

SELECT
    *
FROM
   ClaimDetails
WHERE
    ISDATE(ActualDate) = 0

在这两个字段上，但它没有显示任何行，所以请告诉我我能做什么。

日期字段格式如下所示

谢谢

Answer 1

您应该先设置日期格式。查看您的记录应该是 ymd。

    SET DATEFORMAT ymd;

SELECT *
FROM ClaimDetails
WHERE ISDATE(ActualDate) = 0

Answer 2

按日期字段（从最早到最新）对表格进行排序。如果有 Null 值，则滚动到有数据的第一条记录。现在确保年份是正确的年份。
