-- The following CREATE TABLE statement creates the point_test table,
-- which has a single point column, pt1.

CREATE TABLE point_test (pt1 ST_Point);

-- The ST_Point function converts the point coordinates into a ST_Point
-- geometry before the INSERT statement inserts it into the pt1 column.

INSERT INTO point_test VALUES(
   ST_Point(10.01,20.03,1000)
);
