The DB2 internal geometry representation uses integer coordinate values
that are compressed. The ST_AsBinary and ST_AsText functions are
provided as ways for applications to work with the spatial data in an
industry standard (OGC and ISO) format.
The various spatial constructors accept data in
DB2 stores the vector data in an internal format (using 4 byte Integers).
This format is not official. Reading the data only as blob makes no sense
because you cannot apply any operations on it.
You have to use ST_ASBINARY if you want a WKB representation.
Other possibilities are
ST_ASTEXT f
Hi,
I want to reuse the code that has been written for the DB2 Plugin for
another tool that I am developing.
My question is on how to read the blob data that DB2 uses to store geometry
data. I looked through the DB2 Plugin, from what I understand ST_AsBinary is
used to convert the geometry blob d

Feel free if you would like. I agree its trivial.

the new db2 plugin would be ready to commit. The only showstoppers are
GEOT-2109 and especially GEOT-2095.
GEOT-2109 is an easy problem and if it is ok I would fix it.
Since the development of my imagemosaic-jdbc plugin I have installed all our
target databases (db2,oracle,postgis,mysql) and
