我正在使用此查询
select ST_Segmentize((st_transform(way,3785),100)) from planet_osm_line where road_id = 1640527
这是数据库结构
z_order | integer |
way_area | real |
way | geometry(LineString,900913) |
road_id | integer | not null default nextval('planet_osm_line_road_id_seq'::regclass)
Indexes:
"planet_osm_line_pkey1" PRIMARY KEY, btree (road_id)
"planet_osm_line_index" gist (way)
"planet_osm_line_pkey" btree (osm_id)
错误是
No function matches the given name and argument types. You might need to add explicit type casts.
我该怎么办?我想功能是正确的,我从文档页面属性类型检查也匹配(几何,米)。 为了清楚起见,3785用于转换为米。
