【问题描述】：
给定多个条件的组合，其中包含运算符，例如
section = "ABC" AND type = "A" AND status = "RESPONDED" AND scores NOT_NULL AND scores.productA NOT_NULL AND scores.productA > 10 AND scores.productA < 30
这会导致多个操作，例如
priority = 3 AND hours = 24 AND isQualified = true
目标是找到与该字符串冲突的 JSON 字符串。冲突将是什么时候 相同的条件（相同或不同的顺序）导致不同的动作或导致具有不同值的动作 有一个 mysql 表，将这些 json 字符串存储在一个列中，需要针对该列进行查询
已经尝试过像 JSON_CONTAINS 这样的 MySQL JSON 函数，但是如果嵌套的 json 对象的顺序不同，它就不起作用。 还尝试使用 LIKE 对单个条件进行字符串比较，这些条件有效，但要发生匹配，我们 需要考虑条件的分组和加入它们的运算符。
任何建议都会很棒。理想情况下，能够在 SQL 级别执行此操作会很棒，但结合使用 SQL 来缩小范围，然后对缩小的值进行第二次传递也可能有效。
表示条件和动作的JSON字符串可以像
那样指定{
