ST_Move for MySQL Spatial
A version of my Move functions for SQL Server Spatial and Oracle Spatial is available.
Function Declaration
DELIMITER $$ CREATE FUNCTION `ST_Move` ( p_geometry geometry, p_dX DOUBLE, p_dY DOUBLE, p_round INT ) RETURNS geometry BEGIN -- Processing RETURN geometry; END; DELIMITER ;
Function Testing
SELECT ST_AsText(ST_Move(ST_PointFromText('POINT(0 0)',0), -5.0, 30.1, 1)) AS movedGeom; # movedGeom 'POINT(-5 -5)' -- SELECT ST_AsText(ST_Move(ST_GeomFromText('LINESTRING(0.1 0.2,1.4 45.2)',0),-5.0,30.1, 1)) AS movedGeom; # movedGeom 'LINESTRING(-4.9 30.2,-3.6 31.5)' -- SELECT ST_AsText(ST_Move(ST_GeomFromText('POLYGON((0 0,10 0,10 10,0 10,0 0))',0),-5.0,30.1, 2)) AS movedGeom; # movedGeom 'POLYGON((-5 30.1,5 40.1,5 40.1,-5 30.1,-5 30.1))'
If you think this is of use to you, make a donation and I will release the code to you along with any other MySQL functions I have created.
