Okay, I am one step further, it seemed to be caused by the wrong case in the F_TABLE_NAME and G_TABLE_NAME fields.

But now ogrinfo does not report any geometries, it just reports the attributes from the  F_TABLE_NAME table.Why is this?

C:\Programs\FWTools0.9.9>ogrinfo ODBC:synfonie/synfonie at tatukgistest BIS_LOC_FEA  -summary
INFO: Open of `ODBC:synfonie/synfonie at tatukgistest'

  XCOORD (Real) =     78898
  YCOORD (Real) =    444712
  TAB_LABEL (String) = (null)

  XCOORD (Real) =     78720
  YCOORD (Real) =    444737

Hi list,

I am trying to connect OGR through ODBC to a WKB database. The WKB database was created using TatukGIS (www.tatukgis.com).

I am getting the following error back from OGR:

C:\Programs\FWTools0.9.9>ogrinfo ODBC:synfonie/synfonie at tatukgistest
ERROR 1: No column definitions found for table 'bis_loc_FEA', layer not usable.
INFO: Open of `ODBC:synfonie/synfonie at tatukgistest'
using driver `ODBC' successful.

This is the record in the GEOMETRY_COLUMNS table (in XML format):

<main>
  <DATA_RECORD>
    <F_TABLE_NAME>bis_loc_FEA</F_TABLE_NAME>
    <F_GEOMETRY_COLUMN>GID</F_GEOMETRY_COLUMN>
    <G_TABLE_NAME>bis_loc</G_TABLE_NAME>
    <STORAGE_TYPE>1</STORAGE_TYPE>
    <GEOMETRY_TYPE>11</GEOMETRY_TYPE>
    <COORD_DIMENSION>2</COORD_DIMENSION>
    <MAX_PPR>0</MAX_PPR>
    <SRID>1</SRID>
  </DATA_RECORD>
</main>

The tables are defined as:

CREATE TABLE BIS_LOC
(
  GID           NUMBER(9)                       NOT NULL,
  XMIN          FLOAT(126),
  YMIN          FLOAT(126),
  XMAX          FLOAT(126),
  YMAX          FLOAT(126),
  WKB_GEOMETRY  BLOB
)

CREATE TABLE BIS_LOC_FEA
(
  GID        NUMBER(9)                          NOT NULL,
  LOC_CODE   VARCHAR2(11 BYTE),
  XCOORD     NUMBER(9),
  YCOORD     NUMBER(9),
  TAB_LABEL  VARCHAR2(5 BYTE)
)

What could be the problem? Thanks in advance. It seems TatukGIS does not write SRS info, but that does not seem to be the cause of the above error.

Best regards,
Bart
