How do I use JSON_SEARCH() to find the path of a number in a MySQL JSON array?

Question

Note: This is for MySQL 5.7.

When I attempt to use JSON_SEARCH to find the path to a number value within a JSON array, I get NULL. But when I use JSON_SEARCH to look for a string, I actually get the path.

# String Search Example

SET @json = '[1, 2, 3, "abc"]';
SELECT JSON_SEARCH(@json, 'one', 'abc');

----------
| "$[3]" |
----------

...but when I explicitly search for a number value, I get NULL?

# Number Search Example

SET @json = '[1, 2, 3, "abc"]';
SELECT JSON_SEARCH(@json, 'one', 1);

----------
| NULL   |
----------

What's strange is that JSON_CONTAINS still works as intended with numbers or strings.

JSON_SEARCH函数仅适用于文档中提到的字符串标量：搜索 JSON 值的函数

在这里你可以看到：

报告的错误 - JSON_SEARCH 不搜索非字符串值

报告的功能 -使 JSON_SEARCH 适用于非字符串
