ST_X() method for type ST_Point

Returns the X coordinate of the ST_Point value.


If the point-expression is an empty geometry (ST_IsEmpty()=1), then this method returns NULL.


By default, ST_X uses the original format for a geometry, if it is available. Otherwise, the internal format is used. For more information about internal and original formats, see STORAGE FORMAT clause, CREATE SPATIAL REFERENCE SYSTEM statement.
