MySQL 提供了用于对空间数据执行各种操作的函数。这些函数可以根据它们执行的操作类型分为几大类：MySQL provides functions to perform various operations on spatial data. These functions can be grouped into several major categories according to the type of operation they perform:
用于创建各种格式几何图形的函数（WKT、WKB、内部格式）Functions that create geometries in various formats (WKT, WKB, internal)
用于在格式之间转换几何图形的函数Functions that convert geometries between formats
用于访问几何图形的定性或定量属性的函数Functions that access qualitative or quantitative properties of a geometry
用于描述两个几何图形之间关系的函数Functions that describe relations between two geometries
用于从现有几何图形创建新几何图形的函数Functions that create new geometries from existing ones
