[Sandeep Kumar Jakkaraju]

what is the units of distance parameter in the buffer function  ...

buffer(geom,distance,[integer])   ---> buffer(GEOMFROMTEXT('POINT(28.0 79.0
)'),1);

if my geom is in lat/lon ..... how much will be 1 !!

can some one throw more light on the 3 rd optional parameter !!! the manual
