在SP的select語句中選擇null時日期是01-01-1900

我有一個存儲過程如下。在我的sales_order表中有一個日期列CP_Created_On。在某些日期的表格中，我插入了01-01-1900。現在我正在從表中選擇記錄。當某些行的日期爲01-01-1900時，我想選擇NULL。我以這種方式需要它，因爲我通過DATASET將記錄導出到Excel。請幫忙在SP的select語句中選擇null時日期是01-01-1900

謝謝。

集ANSI_NULLS ON 設定QUOTED_IDENTIFIER ON 去

谷歌，我想這就是你需要 –

我想這樣做什麼，但它並沒有幫助「時，選擇的情況下」。這是我寫情況下 \t \t \t \t \t當CP_Created_On = 1900年1月1日 \t \t \t \t \t然後' \t \t \t \t \t當CP_Created_On！= 1900年1月1日 \t \t \t \t \t然後CP_Created_On \t \t \t結束爲'C關於'\t， – Ankur

您必須將日期包裝到適當的sql日期中。我現在不在電腦後面，但我認爲你的語法不對。（當其他情況下），但我看到其他人正在幫助語法.. –

也許：

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

真棒..！非常感謝..！！那工作..！ – Ankur

NullIF()是你的朋友在這裏！

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

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