【YashanDB知识库】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) ----------- ---------------------------------------------------------------- 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 1 POINT (-137.690708000000001 33.187434000000003) 10 rows fetched.
