ST_SetSRID returns a geometry that is the same as input geometry, except updated with the value input for the spatial reference system identifier (SRID).

Syntax

ST_SetSRID(geom, srid)

Arguments

geom

A value of data type GEOMETRY or an expression that evaluates to a GEOMETRY type.

srid

A value of data type INTEGER that represents a SRID.

Return type

GEOMETRY

The SRID value of the returned geometry is set to srid.

If geom or srid is null, then null is returned.

If srid is negative, then an error is returned.

Examples

The following SQL sets the SRID value of a linestring.

SELECT ST_AsEWKT(ST_SetSRID(ST_GeomFromText('LINESTRING(77.29 29.07,77.42 29.26,77.27 29.31,77.29 29.07)'),50));
