Definition

ST_LineFromText takes a well-known text representation of type ST_LineString and a spatial reference ID and returns an ST_LineString.

Syntax

Oracle

sde.st_linefromtext (wkt clob, srid integer)

SQLite

Example

The linestring_test table is created with a single ln1 ST_LineString column.

The INSERT statement inserts an ST_LineString into the ln1 column using the ST_LineFromText function.

Oracle

CREATE TABLE linestring_test (ln1 sde.st_geometry);
INSERT INTO LINESTRING_TEST VALUES (
 sde.st_linefromtext ('linestring (10.01 20.03, 35.93 19.04)', 4326)
);

SQLite

CREATE TABLE linestring_test (id integer);

SELECT AddGeometryColumn (
 NULL,
 'linestring_test',
 'ln1',
 4326,
 'linestring',
 'xy',
 'null'
);
INSERT INTO LINESTRING_TEST (id, ln1) VALUES (
 1,
 st_linefromtext ('linestring (10.01 20.03, 35.93 19.04)', 4326)
);
