oracle时间格式处理

oracle时间处理：

查询时使用to_char(time,’yyyy-mm-dd hh24:mi:ss’)

insert时使用to_date(‘03-08-2017 09:59:22’, ‘dd-mm-yyyy hh24:mi:ss’)

举例：

insert into t_GIS_GPS (CPH, COORDX, COORDY, TIME, GPSID, ZT, SPEED, DIRECTION, XZQH, DQDZ, JSSJ, YSXX, COORDX_B, COORDY_B, ZHSJ, JZSJ)
values ('宁A11111', '116.336257', '39.982345', to_date('03-08-2017 09:59:22', 'dd-mm-yyyy hh24:mi:ss'), '宁A11111', '0', '5645646', '21', null, null, to_date('03-08-2017 09:59:00', 'dd-mm-yyyy hh24:mi:ss'), '$,宁A11111,2017-08-03 09:59:22,116.336257,39.982345,5645646,21,0,40000000,25,0000000000000000', '116.336257', '39.982345', to_date('03-08-2017 09:59:00', 'dd-mm-yyyy hh24:mi:ss'), null);

oracle日期时间数据类型字段更新例子

update CASH_REPLENISH_PLAN set d_transaction_date = to_date(‘18-03-2016’, ‘dd-mm-yyyy’);

update MOD_RECORD set c_mod_or_che_date = to_date(‘14-03-2016 11:44:03’, ‘dd-mm-yyyy hh24:mi:ss’);

查询时两种方式：

1、select * from t_tjfx_ycrktj where sjscsj>=to_date(‘2018-01-05’,’yyyy–mm-dd’)

2、select * from t_tjfx_ycrktj where to_char(sjscsj,’yyyy-mm-dd’) = ‘2018-01-05’
