研究方向
The issue requests implementing the MySQL UUID SHORT() function. To start, examine how other built in functions like UUID() are implemented in the TiDB codebase. Look at files in the expression package (e.g., builtin uuid.go) for registration and evaluation logic. Ensure to add the function to the builtin list and handle cross version compatibility if needed. The discussion in the issue comments may provide additional context on expected behavior.
