OGR cut data after 510 characted?

[Tero Alén]

Hello everybody

First little background. Our server is Linux server and we are using  
MapServer 4.8.1 (PHPMapscript). Our data is in MySQL database (MySQL  
because other part of our application use it). We use ODBC/OVF to get  
data from database.

Problem is that query result give some unexpected result. If I make  
same query many times (using refresh) MapServer returns randomly two  
or three different results.

When I used ogrinfo to test our ovf file I found that it will cut the  
geometry fields value after 510 character. The data is correct in  
database when I make query by hand. Yes, we are using MySQL's spatial  
extension and geometry column's type is geometry.

ogrinfo also returns following error: ERROR 1: SetAttributeFilter()  
not supported on ExecuteSQL() results.

Thanks for any help.
