如何使用jdbc向YashanDB批量插入gis数据
以gis表为例：
drop table gis;
create table gis(id number not null, pos st_geometry not null);
使用如下的java代码片断，可以向gis表中插入POINT类型的gis数据：
|
conn.setAutoCommit(false); PreparedStatement ps = conn.prepareStatement("insert into gis values(?,ST_GEOMFROMTEXT(?))"); for(int i = 0; i < 10; i++) { ps.setInt(1, 1); ps.setString(2, "POINT(-137.690708 33.187434)"); ps.addBatch(); } ps.executeBatch(); conn.commit(); |
最终效果：
SQL> select id, st_astext(pos) from gis;
ID ST_ASTEXT(POS)
