This SQL element is a shortcut for the User Defined Method SQL element with the User Defined Type field set to ST_GEOSEQUENCE. Selecting this element will display a listing of methods for the ST_GEOSEQUENCE type, described in the following table.
| Method | Definition |
|---|---|
| Clip | Returns a GeoSequence type containing the subset of points and associated data that lie between the two timestamp input arguments. |
| GetFinalT | Returns the TimeStamp of the last point of a GeoSequence. |
| GetInitT | Returns the TimeStamp of the first point of a GeoSequence. |
| GetUserFld | Returns the user field specified by fldIndex for the point specified by index for a GeoSequence type. |
| GetUserFldCount | Returns the number of user fields associated with each point of a GeoSequence. |
| HeadingN | Returns the heading for the specified point of a GeoSequence. |
| LinkID_GET | Get the link ID of a specified point in a GeoSequence. |
| LinkID_SET | Set the link ID of a specified point in a GeoSequence. |
| SpeedN | Returns the approximate speed at a specified point (SpeedN(index INTEGER)) or between two points (SpeedN(iBegin INTEGER, iEnd INTEGER)) for a GeoSequence type. |
| SpeedN2 | Returns the approximate speed at a specified point (SpeedN(index INTEGER)) or between two points (SpeedN(iBegin INTEGER, iEnd INTEGER)) for a GeoSequence type. |
