ST_MPolyFromText

Note:

Oracle and SQLite only

Definition

ST_MPointFromText takes a well-known text (WKT) representation of type ST_MultiPolygon and a spatial reference ID and returns an ST_MultiPolygon.

Syntax

Oracle

sde.st_mpolyfromtext (wkt clob, srid integer)

SQLite

st_mpolyfromtext (wkt text, srid int32)

Return type

ST_MultiPolygon

Example

The multipolygon_test table is created with the single ST_MultiPolygon mpl1 column.

The INSERT statement inserts an ST_MultiPolygon into the mpl1 column using the ST_MpolyFromText function.

Oracle

CREATE TABLE mpolygon_test (mpl1 sde.st_geometry);

INSERT INTO MPOLYGON_TEST VALUES (
 sde.st_mpolyfromtext ('multipolygon (((10.01 20.03, 10.52 40.11, 30.29 41.56, 
31.78 10.74, 10.01 20.03), (21.23 15.74, 21.34 35.21, 28.94 35.35, 
29.02 16.83, 21.23 15.74)), ((40.91 10.92, 40.56 20.19, 50.01 21.12, 
51.34 9.81, 40.91 10.92)))', 4326)
);
