The functions described in this section perform operations on JSON values. 本节中描述的函数对JSON值执行操作。For discussion of the JSON data type and additional examples showing how to use these functions, see Section 11.5, “The JSON Data Type”.有关JSON数据类型的讨论以及如何使用这些函数的其他示例,请参阅第11.5节,“JSON数据类型”

For functions that take a JSON argument, an error occurs if the argument is not a valid JSON value. 对于采用JSON参数的函数,如果参数不是有效的JSON值,则会发生错误。Arguments parsed as JSON are indicated by json_doc; arguments indicated by val are not parsed.解析为JSON的参数由JSON_doc表示;val表示的参数不被分析。

A set of spatial functions for operating on GeoJSON values is also available. 还提供了一组用于操作GeoJSON值的空间函数。See Section 12.17.11, “Spatial GeoJSON Functions”.参见第12.17.11节,“空间GeoJSON函数”
