Oracle-时间与字符串转换
UPDATE_TIME 是时间，直接转成字符串
SELECT to_char(MAX(UPDATE_TIME), ‘yyyy-mm-dd hh24:mi:ss‘) as lastUpdateTime,
to_char(sysdate, ‘yyyy-mm-dd hh24:mi:ss‘) as accountTime
FROM QLK_AREA;
-- LASTUPDATETIME 是字符串，先转成时间，再转成字符串
SELECT to_char(to_date(MAX(LASTUPDATETIME), ‘yyyymmddhh24miss‘),
‘yyyy-mm-dd hh24:mi:ss‘) as lastUpdateTime,
to_char(sysdate, ‘yyyy-mm-dd hh24:mi:ss‘) as accountTime
FROM PSN_MZ_LHDJXX_BL;
