Re: unknown function DISTANCE() in mysql 5.1.30 ??
Note
Currently, MySQL does not implement these functions according to the specification. Those that are implemented return the same result as the corresponding MBR-based functions. This includes functions in the following list other than Distance() and Related().
These functions may be implemented in future releases with full support for spatial analysis, not just MBR-based support.
