Hi Dhireendra Kumar!
   
  I'm going to start working with mysql as my spatial database, but have no idea how to use fdo2fdo to import geometry from .shp file to MySQL. would you please give me information about FDO2FDO,(I mean how I should prepare to use it, Is there any documentation for this task?). 
   
  Thank you very much for your cooperation,
