## 描述
+
+`sub_replace` 函数用于替换字符串中的子字符串。可以指定要替换的子字符串和替换的目标字符串，返回用`new_str` 字符串替换 `str`
中从 `start` 开始长度为len的新字符串。其中 `start`, `len` 为负整数，返回 NULL, 且 `len` 的默认值为
`new_str` 的长度。

## 语法

+`VARCHAR sub_replace(<str>, <new_str>, <start[, len]>)`
+
+## 参数
+
+| 参数 | 说明 |
+| -- | -- |
+| `<str>` | 要进行替换操作的目标字符串 |
+| `<new_str>` | 用于替换的目标字符串 |
+| `<start[, len]>` | start 表示替换操作开始的位置，可选参数，表示要替换的子字符串长度 |
Review Comment:
start 和 len 是两个参数吧？
start 和 len 都可选吗？如果是的话应该是 `[ ,<start> [ , <len> ] ]`
如果只有 len 可选，应该是 `,<start> [ , <len> ]`

-## sub_replace
-### Description
-#### Syntax
+## Description
-`VARCHAR sub_replace(VARCHAR str, VARCHAR new_str, INT start[, INT len])`
+The `sub_replace` function is used to replace substrings within a string. You
can specify the substring to be replaced and the target string to replace it
with. It returns a new string where the substring starting from `start` with
length `len` in `str` is replaced by `new_str`. If `start` or `len` is a
negative integer, it returns NULL. The default value for `len` is the length of
`new_str`.
-Return with new_str replaces the str with length and starting position from
start.
-When start and len are negative integers, return NULL.
-and the default value of len is the length of new_str.
+## Syntax
-### example
+`VARCHAR sub_replace(<str>, <new_str>, <start[, len]>)`

不要带类型

最好参数中间能加一些空格，提升阅读便捷程度
