ST_TOUCHES

Description

Determines whether the geometry shape1 touches the geometry shape2. (i.e., whether the boundaries of the two geometries intersect but their interiors do not)

Note

Supported since Apache Doris 2.1.10.

Syntax

ST_TOUCHES( <shape1>, <shape2> )

Parameters

Parameters	Instructions
<shape1>	The passed geometry used to determine whether it touches shape2
<shape2>	The passed geometry used to determine whether it touches shape1

Return Value

Return 1: shape1 The graph touches the graph shape2

Return 0: shape1 The graph does not touch the graph shape2

Examples

SELECT ST_Touches(ST_Polygon("POLYGON ((0 0, 10 0, 10 10, 0 10, 0 0))"), ST_LineStringFromText("LINESTRING (10 5, 15 5)"));
