world borders into sql

i am now imported boundaries with shp2pgsql.

this is one item. how can i from this get coordinate?

gid | cat | fips_cntry | cntry_name | the_geom / 1 | 15 | AY | Antarctica | 010600000001000000010300000001000000260000003BC .. (snipped)

Use the st_astext function in your query, like "select cntry_name,st_astext(the_geom) from tablename..."

thank you.

your sql select work very well, but border is little moved. see picture: http://s18.postimg.org/6s75eqjy1/border.png

on northern hemisphere is latitude moved lower about 0.2 and on southern hemisphere is latitude moved higher about 0.2

i use this function for convert coordinate

double AQConverter::MercatorToLon(double x){

double rMajor = 6378137; //Equatorial Radius, WGS84

double shift  = M_PI * rMajor;

double lon    = x / shift * 180.0;

return lon;

}

double AQConverter::MercatorToLat(double y){

double rMajor = 6378137; //Equatorial Radius, WGS84

double shift  = M_PI * rMajor;

double lat    = y / shift * 180.0;

lat = 180.0/ M_PI * (2 * qAtan(qExp((lat * M_PI) / 180.0)) - M_PI / 2.0);

return lat;

}
