import java.sql.Timestamp;import java.text.DateFormat;import java.text.SimpleDateFormat;import java.util.Date;
DateFormat df =newSimpleDateFormat("yyyy-MM-dd HH:mm:ss:SSS");
Date date = null;
Timestamp st = null;
date = df.parse("2020-05-24 22:22:54:423");
st =newjava.sql.Timestamp(date.getTime());//从数据库取出毫秒级字段()to_char(t.CCOLLECTIONTIME,'yyyy-mm-dd hh24:mi:ss.ff3')
2.向空间坐标系插入数据的例子
insert into monitor_point_geometry(pointcode,geometry)
values ('630011326050',
MDSYS.SDO_GEOMETRY(2003,8307,NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1,2,1),、MDSYS.SDO_ORDINATE_ARRAY(112.98097,28.21696)));
3.分页查询例子
//查询10-20条数据
SELECT * FROM
(SELECT
ROWNUM AS rowno,
t.*
FROM
table_name t
where ROWNUM <=20) table_alias
WHERE
table_alias.rowno >=10;
4.left join 1对n的情况取其中一条
select
t.ccollectionagencies ,
ats.bikenumber,
ats.company
from
table_name t
left join
(select
MAX(inputtime) AS REPORTTIME,
company,bikenumber
from
left_table_name
group by
bikenumber,company) ats
on
ats.bikenumber = t.ccarnumber
```
