This function returns true if trajectory objects 1 and 2 are spatially equal within the specified time range.
Syntax
boolean ST_equals(trajectory traj1, trajectory traj2, tsrange range);
boolean ST_equals(trajectory traj1, trajectory traj2, timestamp t1, timestamp t2);Parameters
| Parameter | Description |
|---|---|
| traj | The trajectory object. |
| t1 | The start time. |
| t2 | The end time. |
| range | The time range. |
Examples
Select ST_equals((Select traj from traj_table where id=1), (Select traj from traj_table where id=2), '2010-1-1 13:00:00', '2010-1-1 14:00:00');
