我有一个存储过程如下。在我的 sales_order 表中有一个 date 列CP_Created_On。在某些行日期的表格中，我插入为01-01-1900. 现在我从表中选择记录。我想选择NULL某些行的日期是什么时候01-01-1900。我想要这种方式，因为我通过DATASET. 请帮忙

谢谢。

设置 ANSI_NULLS ON 设置 QUOTED_IDENTIFIER ON 去

NullIF()是你的朋友！

DECLARE @d date = '1900-01-01';

SELECT @d As d
     , NullIf(@d, '1900-01-01')
     , NullIf(Current_Timestamp, '1900-01-01')

也许：

SELECT CASE 
         WHEN cp_created_on = '19000101' THEN NULL 
         ELSE cp_created_on 
       END AS CP_Created_On 
FROM   dbo.TableName
