Updating xml clob in oracle
SDO_Geometry_Array),0.005) as geom from rd_road ro, rd_ro_sec ros where ros.rd_ro_ident = ro.rd_ro_ident and ro.rd_ro_ident = 1895101 group by ro.rd_ro_ident, ro.rd_ro_name, ro.com_code; took hours. A simple query learned I had 150 roads with more segments, and a maximum of 125 segments in the database.I could not just simply ignore them :) So this was not going to work either. I just wanted to throw all linestrings together into one geometry. Querying the geometries was really easy, so what if I joined the geometries outside of oracle? But there is a simple solution: convert the strings to WKT, and join all to make sure the open cursors were released.I used the boring/easy/manual approach, in short: So a person could be linked to different “personifiable” things, and sometimes the meaning of the relation can change (e.g.a person could be an owner or a renter –expressed by the relation type).So I decided to write a little script, and issue a sql statement for each single road, allowing me to track progress and added restartibility.For each road I issued a statement like: insert into street_geoms select ro.rd_ro_ident, ro.rd_ro_name, ro.com_code, sdo_aggr_set_union(CAST(COLLECT(ros.rd_ros_geometry) AS mdsys.And I had to make sure not to build a string literal which was too long (ORA-06550). The data is spanning two countries: Belgium and the Netherlands.But in the end I was able to join the road-sections for the 45.000 roads in approx 1.5h, which is not blindingly fast, but faster than 1 single We are in the process of migrating an old GIS system. Our system does something awful: all data is stored in RD (the dutch coordinate system, using Oracle SRID 90112).
We are using oracle 11, so my initial process was the following delete from mdsys.cs_srs where srid=31370; Insert into MDSYS.I have a little example demonstrating this, and so I imagined to submit a bug. Since you can just render html in any column, we do for instance the following for our KLIP platform : In our first we show our internal identifier, and the external identifier.Unfortunately the bug-tracker requires an OS-Geo account, and to get insert into original_be_geometries(originally_type, originally_id, geom) values ('Test', 2, ST_set SRID(ST_Geom From Text('LINESTRING Z (1.23445 2.234455 3.33445, 4.12345 5.12345 6.56789, 7.012 8.111 9.0001)'), 31370) ); :) [UPDATE] My team-mate has Postgis 2.2.2 and there this just works. In code this looks like this: But now the problem is: how can we, when filtering, automatically look for both fields?The root cause is that ruby on windows (or openssl) has no default root certificate.So I found a good description how to fix that on windows.
