ovf layer (mysql) won't show

[Tero Alén]

Hi,

I have problems to showing ovf layer on MapServer 4.8.1. Layer contains
linestring-geometry from MySQL 5.0.18.

MapServer doesn't print any errors but layer won't show. Could somebody tell
me what's wrong?

Here is what is in ovf-file:

<OGRVRTDataSource>

    <OGRVRTLayer name="article_poly">
        <SrcDataSource>ODBC:opus at myodbc</SrcDataSource>
        <SrcSQL>select id, astext(article_poly.linest) as geometry from
article_poly</SrcSQL>
        <GeometryField encoding="WKT" field="geometry"/>
     </OGRVRTLayer>

</OGRVRTDataSource>

And what I get from ogrinfo:

ERROR 4: Update access not supported for VRT datasources.
Had to open data source read-only.

using driver `VRT' successful.

And layer definition from map-file:

       LAYER
                CONNECTION "ovf/espoo.ovf"
                CONNECTIONTYPE OGR
                NAME article_poly
                TYPE LINE
                STATUS DEFAULT
                CLASS
                 DEBUG ON
                  STYLE
                   COLOR 255 0 0
                  END
                END

        END
