12.16.7.2 Point Property Functions

A Point consists of X and Y coordinates, which may be obtained using the following functions:

  • ST_X(p)

    Returns the X-coordinate value for the Point object p as a double-precision number.

    mysql> SELECT ST_X(Point(56.7, 53.34));
    +--------------------------+
    | ST_X(Point(56.7, 53.34)) |
    +--------------------------+
    |                     56.7 |
    +--------------------------+
    

    ST_X() and X() are synonyms.

  • ST_Y(p)

    Returns the Y-coordinate value for the Point object p as a double-precision number.

    mysql> SELECT ST_Y(Point(56.7, 53.34));
    +--------------------------+
    | ST_Y(Point(56.7, 53.34)) |
    +--------------------------+
    |                    53.34 |
    +--------------------------+
    

    ST_Y() and Y() are synonyms.

  • X(p)

    ST_X() and X() are synonyms. For more information, see the description of ST_X().

    X() is deprecated; expect it to be removed in a future MySQL release. Use ST_X() instead.

  • Y(p)

    ST_Y() and Y() are synonyms. For more information, see the description of ST_Y().

    Y() is deprecated; expect it to be removed in a future MySQL release. Use ST_Y() instead.
