Hi Frank,

one last question, was this done after GDAL 1.3.1? Using your fwtools Mapserver binaries I can display the layer, but not using DM Solutions' binaries (Mapserver 4.6.1 combined with GDAL 1.3.1 from maptools.org). Or were there changes in Mapserver for this after 4.6.1?

If this was done after GDAL 1.3.1, will there be a GDAL 1.3.2 release just before the final Mapserver 4.8 release?

Best regards.
Bart

Hi list,

I have done a bit more analysis but have been unable to solve this unfortunately.

1) creating a view with all the columns does not make a difference, still no geometry is read (only XMIN, XMAX etc.)
2) properly filling the SRS table and column does not make any difference.

I have attached an example BLOB field, maybe somebody could judge from this what is going wrong.

I tried with CPL_DEBUG ON but could not get any useful messages out of ogrinfo. Btw my data is (multi) polygon data.

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?

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
