[MonetDB-users] Fwd: wkb representation of a geometry
Hi,
I need to get the Well Known Binary representation of a geometry but I didn't find any function in documentation to do this. Any ideas?
George,
where do you need to get the Well Known Binary representation of a geometry? As documentation? In C? In MAL? In SQL?

I need something like that SELECT AsWKB('POINT(1, 2)');

Another example would the following. Suppose that we have the table geometries(id INT, shape GEOMETRY) and we would like to retrieve the WKB and WKT representation of the geometry. For example we would like to ask the following query:
select id, AsWKB(geo) AS GeoWKB, AsWKT(geo) AS GeoWKT from geometries

I have tried GeomFromText but it doesn't seem to return WKB.

Assume that you have a table like geometries(id INT, shape GEOMETRY) and the query SELECT id, GeomFromText(shape) FROM geometries . Would this query return the WKB representation of the geometries "directly" or is there an intermediate step where the geometry is being converted to WKT (WKB --> WKT --> WKB)?

In Postgres the WKB representation of a geometry is returned as a byte array. For example,
LGD=# SELECT ST_AsBinary(ST_GeomFromText('POINT(1 2)',-1)); st_asbinary ---------------------------------------------- \x0101000000000000000000f03f0000000000000040 (1 row)

This is not available in MonetDB (as far as I can tell by quickly looking at the code).
What you get when you do SELECT * FROM t; where t contains a column of type geometry is the string representation of the internal (WKB) representation produced by the function GEOSGeomToWKT(). I.e., one conversion WKB->WKT.
If you do SELECT GeomFromText(g,0) FROM t; where g is a column of type geometry, it does a conversion WKB->WKT->WKB->WKT because an intermediate table is created with the result of GeomFromText. GeomFromText expects a string (varchar) and so an automatic WKB->WKT conversion takes place. GeomFromText itself does the WKT->WKB conversion, and you get an extra WKT->WKB conversion because the select produces a textual representation of the column.

"...and you get an extra WKT->WKB conversion because the select produces a textual representation of the column. ..." You mean "WKB->WKT conversion", don't you? Why is this last conversion needed? Isn't it extra work for monetdb? Is there any way to tweak the code in order to bypass the last conversion ?

In Postgres the WKB representation of a geometry is returned as a byte array. For example,

This is not available in MonetDB (as far as I can tell by quickly looking at the code).
What you get when you do SELECT * FROM t; where t contains a column of type geometry is the string representation of the internal (WKB) representation produced by the function GEOSGeomToWKT(). I.e., one conversion WKB->WKT.
If you do SELECT GeomFromText(g,0) FROM t; where g is a column of type geometry, it does a conversion WKB->WKT->WKB->WKT because an intermediate table is created with the result of GeomFromText. GeomFromText expects a string (varchar) and so an automatic WKB->WKT conversion takes place. GeomFromText itself does the WKT->WKB conversion, and you get an extra WKT->WKB conversion because the select produces a textual representation of the column.

Undoubtedly I did.
Why is this last conversion needed? Isn't it extra work for monetdb?
This has to do with the way data is sent from the server to the client.
Is there any way to tweak the code in order to bypass the last conversion ?
Only by not sending the results to the client. If you want to do something with the results in your client application, you will need to send them, but if you want to work further using SQL, you should try to keep the data inside the server, for instance by storing them in a temporary table.
There is currently no way to avoid the WKB->WKT conversion in the client-server protocol.
