ST_SRID

Returns the Spatial Reference Identifier (SRID) for the geometry. This integer represents the coordinate system used.

Syntax

ST_SRID(g)
SRID(g)

Description

Returns an integer indicating the Spatial Reference System ID for the geometry value g.

In MariaDB, the SRID value is just an integer associated with the geometry value. All calculations are done assuming Euclidean (planar) geometry.

ST_SRID() and SRID() are synonyms.

Examples

SELECT SRID(GeomFromText('LineString(1 1,2 2)',101));
+-----------------------------------------------+
| SRID(GeomFromText('LineString(1 1,2 2)',101)) |
+-----------------------------------------------+
|                                           101 |
