I used below query from http://lists.mysql.com/mysql/219805
SET @center = GeomFromText( 'POINT(39.78824896727801 30.50930339115439)' )
;# MySQL returned an empty result set (i.e. zero rows).
SET @radius = 0.005;# MySQL returned an empty result set (i.e. zero rows).
SET @bbox = GeomFromText( CONCAT( 'POLYGON((', X( @center ) - @radius , ' ',
Y( @center ) - @radius , ',', X( @center ) + @radius , ' ', Y( @center ) -
@radius , ',', X( @center ) + @radius , ' ', Y( @center ) + @radius , ',',
X( @center ) - @radius , ' ', Y( @center ) + @radius , ',', X( @center ) -
@radius , ' ', Y( @center ) - @radius , '))' ) ) ;# MySQL returned an empty
result set (i.e. zero rows).
SELECT astext( point ) , Distance( @center , point ) AS dist
FROM psn.psn_place
WHERE MBRContains( @bbox , point )
ORDER BY dist
LIMIT 10;
I don't know type of 'dist' in this result, I need 'dist' column in meter
format.
