Syntax\n------\n\nST_IsEmpty(g)\nIsEmpty(g)\n\nDescription\n-----------\n\nIsEmpty is a function defined by the OpenGIS specification, but is not fully implemented by MariaDB or MySQL.\n\nSince MariaDB and MySQL do not support GIS EMPTY values such as POINT EMPTY, as implemented it simply returns 1 if the geometry value _g_ is invalid, 0 if it is valid, and NULL if the argument is NULL.\n\nST_IsEmpty() and IsEmpty() are synonyms.\n\nURL: https://mariadb.com/docs/server/reference/sql-statements/geometry-constructors/geometry-properties/st_isempty
