### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Version trunk version , commit_id = `2c58724c84021ae5c9fdd5ba304808b1e79191d4` ### What's Wrong? The `replace` function cannot replace corecctly when the old substring is at the beginning of the original string. ```sql MySQL [(none)]> select replace('http://www.baidu.com:9090','http', 'ftp'); +-----------------------------------------------------+ | replace('http://www.baidu.com:9090', 'http', 'ftp') | +-----------------------------------------------------+ | http://www.baidu.com:9090 | +-----------------------------------------------------+ 1 row in set (0.034 sec) ``` ### What You Expected? The correct result is : ```sql mysql> select replace('http://www.baidu.com:9090','http', 'ftp'); +-----------------------------------------------------+ | replace('http://www.baidu.com:9090', 'http', 'ftp') | +-----------------------------------------------------+ | ftp://www.baidu.com:9090 | +-----------------------------------------------------+ 1 row in set (0.02 sec) ``` ### How to Reproduce? ```sql MySQL [(none)]> select replace('http://www.baidu.com:9090','http', 'ftp'); +-----------------------------------------------------+ | replace('http://www.baidu.com:9090', 'http', 'ftp') | +-----------------------------------------------------+ | http://www.baidu.com:9090 | +-----------------------------------------------------+ 1 row in set (0.034 sec) ``` ### Anything Else? _No response_ ### 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.
