ST_SetSRID - Amazon Redshift

Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the blog post that was published on June 30, 2025.

ST_SetSRID

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));
st_asewkt ------------- SRID=50;LINESTRING(77.29 29.07,77.42 29.26,77.27 29.31,77.29 29.07)
