Question

我是SQL开发人员的新手，但每次我收到查询时都会将时间戳更改为可读日期格式，但我希望我的结果是时间戳，因为它们在数据库中。

Answer 1

请转到：工具/首选项/数据库/ NLS，并将日期格式和时间戳格式设置为您想要的格式。

Oracle存储日期和时间戳类型，但根据NLS设置显示它。您可以致电alter session set NLS_TIMESTAMP_FORMAT = 'YYYY-MM-DD HH:MI:SS.FF';或在客户端工具中设置这些NLS设置。

我终于找到了要做的事，我刚刚从

更改了我的SQL查询

SELECT ALARMID,ALARMNAME,ALERTKEY,SITENAME,FIRSTOCCURRENCE,LASTOCCURRENCE,CLEARTIME,NODE,MANAGER
FROM ACROSSFM1.REPORTER_STATUS 
WHERE ALARMID IN ('301','21801','22202','29240','14001','29201','199087342',
'199087337','198099803','199083022','199066019','199083023',
'198094419','198094422','S1 Link is Broken',
'CELL LOGICAL CHANNEL AVAILABILITY SUPERVISION','UtranCell_NbapMessageFailure',
'UtranCell_ServiceUnavailable','UtranCell_RBSLocalCellNotAdded',
'Heartbeat Failure','ResourceConfigurationFailure','ServiceUnavailable',
'Resource Activation Timeout','ResourceAllocationFailure','S1apLinkDown')
AND Type = 2
AND LASTOCCURRENCE > (SYSDATE-(1/24));

到

SELECT ALARMID,ALERTKEY,ALARMNAME,SITENAME,CEIL(((FIRSTOCCURRENCE)- (TO_DATE('1970-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'))) * 86400),CEIL(((LASTOCCURRENCE)- (TO_DATE('1970-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'))) * 86400),CEIL(((CLEARTIME)- (TO_DATE('1970-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'))) * 86400),NODE,MANAGER
FROM ACROSSFM1.REPORTER_STATUS
WHERE ALARMID IN ('301','21801','22202','29240','14001','29201','199087342','199087337','198099803','199083022','199066019','199083023','198094419','198094422','S1 Link is Broken','CELL LOGICAL CHANNEL AVAILABILITY SUPERVISION','UtranCell_NbapMessageFailure','UtranCell_ServiceUnavailable','UtranCell_RBSLocalCellNotAdded','Heartbeat Failure','ResourceConfigurationFailure','ServiceUnavailable','Resource Activation Timeout','ResourceAllocationFailure','S1apLinkDown','21807','21825')
        AND Type = 2
        AND LASTOCCURRENCE > (SYSDATE-(1/24));

我会说

CEIL(((FIRSTOCCURRENCE)- (TO_DATE('1970-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'))) * 86400)

完成了这项工作。
