- Builds a JSON object string by aggregating key-value expressions into a
single JSON object.
+ 通过将 key-value 聚合到单个 JSON 对象中，构建 JSON 对象字符串。
- The key expression must return a non-nullable character string. Value
expressions can be
- arbitrary, including other JSON functions. If a value is `NULL`, the `ON
NULL` behavior
- defines what to do. If omitted, `NULL ON NULL` is assumed by default.
+ 键表达式必须返回不为空的字符串。值表达式可以是任意的，包括其他 JSON 函数。
+ 如果值为 `NULL`，则 `ON NULL` 行为定义了要执行的操作。如果省略，默认情况下假定为 `NULL ON NULL`。
- Note that keys must be unique. If a key occurs multiple times, an error
will be thrown.
+ 请注意，键必须是唯一的。如果一个键出现多次，将抛出一个错误。
- This function is currently not supported in `OVER` windows.
+ 此函数目前在 `OVER` windows 中不受支持。
