### Description * parent https://github.com/apache/inlong/issues/10796 * A string comparison function in MySQL that compares the lexicographical order of two strings, str1 and str2. This function returns an integer value representing the result of comparing two strings ### Use case * STRCMP('apple', 'apple')--returns 0, * STRCMP('apple', 'banana')--returns 1, 'apple' is less than 'banana' in lexicographical order, so the result is -1 * STRCMP('apple', 'applepie')--returns -1, 'apple' is less than 'banana' in lexicographical order, so the result is -1 * STRCMP('apple', 'applepie')--returns -1, Although the first five characters are the same, 'apple' is less long than 'applepie', so the result is -1 * STRCMP('', 'apple')--returns -1, An empty string is always less than any non-empty string, so the result is -1 * STRCMP('Apple', 'apple')--returns -1, By default, MySQL comparisons are case-sensitive, so the ASCII value of 'A' is less than 'a', resulting in -1 ### Are you willing to submit PR? - [X] Yes, I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
