ST_GeoHash was added in MariaDB 11.7.

Syntax

ST_GeoHash(longitude, latitude, max_length)
ST_GeoHash(point, max_length)

Description

Returns the geohash corresponding to the input values, or NULL if any argument is NULL. Geohashes encode latitude and longitude coordinates into a text string made up only of numeric and lowercase latin letter characters.

The longitude parameter is a numeric value in the interval [180, -180]. latitude is a numeric value in the interval [90, -90].

In the case of point, the x coordinate is treated as the latitude and the y coordinate is treated as the latitude. The same constraints apply.

The max_length parameter is the upper limit on the resulting string size and cannot exceed 100.

Examples

SELECT ST_GeoHash(ST_GeomFromText('POINT(1 1)'),15), ST_GeoHash(0,30,15);
