Question

需要帮助。

我正在尝试从toad中提取数据，其中一列（EFFECTIVE_FROM）包含时间戳中的日期dd / mm / yy hh：mi：ss：mmmAM例如（2015年5月8日下午2:14:19）但我希望DD-MM-YYYY的日期即2015年5月8日

我使用以下查询

请帮助

SELECT B.USER_NAME AS CREATED_BY, A.CREATION_DATE, C.USER_NAME, A.LAST_UPDATE_DATE, A.PFIZER_ITEMCODE, A.SYSTEM_ITEMCODE AS ORACLE_ITEM_CODE,
A.ITEM_DESCRIPTION, A.BATCH_NUMBER, A.MFR_CODE, A.MFR_DESC AS MFR_DESCRIPTION, A.MFR_DATE, A.EXPIRY_DATE, A.EFFECTIVE_FROM  
FROM xxdhl_pf_batch_pricing A,
     fnd_user B,
     fnd_user c
where 1=1
AND A.CREATED_BY = B.USER_ID
AND A.LAST_UPDATED_BY = C.USER_ID
AND A.SYSTEM_ITEMCODE = 'xx' AND A.BATCH_NUMBER = 'yy'

Answer 1

假设EFFECTIVE_FROM是日期或时间戳字段，您可以使用TO_CHAR函数：

SELECT TO_CHAR(A.EFFECTIVE_FROM,'DD-MON-YYYY'), B.USER_NAME AS CREATED_BY, A.CREATION_DATE, C.USER_NAME, A.LAST_UPDATE_DATE, A.PFIZER_ITEMCODE, A.SYSTEM_ITEMCODE AS ORACLE_ITEM_CODE,
A.ITEM_DESCRIPTION, A.BATCH_NUMBER, A.MFR_CODE, A.MFR_DESC AS MFR_DESCRIPTION, A.MFR_DATE, A.EXPIRY_DATE, A.EFFECTIVE_FROM
FROM xxdhl_pf_batch_pricing A,
     fnd_user B,
     fnd_user c
where 1=1
AND A.CREATED_BY = B.USER_ID
AND A.LAST_UPDATED_BY = C.USER_ID
AND A.SYSTEM_ITEMCODE = 'xx' AND A.BATCH_NUMBER = 'yy'

Answer 2

您可以使用TO_DATE()，如下所示：

SELECT B.USER_NAME AS CREATED_BY,
   A.CREATION_DATE,
   C.USER_NAME,
   A.LAST_UPDATE_DATE,
   A.PFIZER_ITEMCODE,
   A.SYSTEM_ITEMCODE AS ORACLE_ITEM_CODE,
   A.ITEM_DESCRIPTION,
   A.BATCH_NUMBER,
   A.MFR_CODE,
   A.MFR_DESC AS MFR_DESCRIPTION,
   A.MFR_DATE,
   A.EXPIRY_DATE,
   to_date(A.EFFECTIVE_FROM, 'DD-MON-YYYY')
FROM xxdhl_pf_batch_pricing A, fnd_user B, fnd_user c
where 1 = 1
   AND A.CREATED_BY = B.USER_ID
   AND A.LAST_UPDATED_BY = C.USER_ID
   AND A.SYSTEM_ITEMCODE = 'xx'
   AND A.BATCH_NUMBER = 'yy'

Answer 3

如果您希望将月份写成您的示例（2015年5月8日），则不需要“MM”。 MM会给你一个月号，所以你最终会得到'08 -05-2015'。

使用：

to_char(A.EFFECTIVE_FROM,'DD-MON-YYYY')

请参阅此处的格式模型： http://docs.oracle.com/cd/B19306_01/server.102/b14200/sql_elements004.htm
