Question

我有一个存储过程如下。在我的sales_order表中，有一个日期列CP_Created_On。在某些行日期的表格中，我插入了01-01-1900。现在我从表中选择记录。我希望在某些行的日期为NULL时选择01-01-1900。我想以这种方式，因为我通过DATASET将记录导出到excel。请帮忙

感谢。

将ANSI_NULLS设置为ON 设置QUOTED_IDENTIFIER 去

Answer 1

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')

Answer 2

也许：

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

Demo

当日期为01-01-1900时，在SP中的select语句中选择null
