Find if a polyline is a subset of a bigger polyline

I am entirely new to MySQL but I have intermediate level knowledge of MS SQL 2000, 2008. I am familiar with a little of spatial oracle.

I want to know if I can use MySQL for writing Spatial Queries at all. If so, which version of it?

I want to write a query which takes in source and destination geo-locations (Lat, Lng), computes the route(s) covering those two points in public transportation (buses). (Assume I have the GIS data with me.)

That would involve finding the routes (polylines) from my GIS which contain the two points (source and deestination); finding the distance between them along each of the routes, etc.

I would want to get started provided this can be achieved with the "spatial" features of MySql.

Also, can any one plz suggest some source to get myself started and going.

I hardly might have to write at most 2 spatial queries for my application. Any suggestions would be appreciated.
