Determine whether two geometries do not intersect, that is, whether their DE-9IM intersection matrix is FF*FF****.

Syntax

ST_Disjoint(geo1, geo2);

geo1: The first input geometry.
Type: ST_GEOMETRY(ANY)
geo2: The second input geometry.
Type: ST_GEOMETRY(ANY)

Returns

A value of type BOOL that is TRUE if the two geometries do not intersect; otherwise FALSE.

Examples

SELECT inza..ST_Disjoint(inza..ST_WKTToSQL('LINESTRING (0 0, 10 10)'),
            inza..ST_WKTToSQL('LINESTRING (0 5, 10 5)'));
