A MySQL Compatible SQL Parser
Role in this project:
Back-end Developer
Back-end DeveloperContributions:27 commits, 31 PRs, 101 comments in 2 years 6 months
Contributions summary:Chuan contributed to the MySQL parser by implementing features related to default values and generated column definitions. Their work involved modifying the parser to handle the fraction of `CURRENT_TIMESTAMP` in default values and implementing error messages for illegal year type definitions. They also provided support for `CREATE USER` extensions and fixed the syntax for the `LOAD DATA` statement and `ALTER TABLE` syntax. These commits demonstrate a focus on enhancing the parser's capabilities and ensuring compatibility with MySQL syntax and features.

TiDB - the open-source, cloud-native, distributed SQL database designed for modern applications.
Role in this project:Back-end Developer / Database Engineer
Back-end Developer / Database EngineerContributions:115 commits, 99 PRs, 550 comments in 4 years 2 months
Contributions summary:Chuan implemented several new built-in functions for the TiDB database, focusing on miscellaneous functionalities. The contributions include adding functions for IPv6 address validation, computing any value, generating UUIDs, and checking IPv4 addresses. Furthermore, the user enhanced existing time-related functions such as 'TO_DAYS', 'TO_SECONDS', and 'TIMESTAMPADD', and fixed the behavior of trim functions as well as the handling of datetime precision to improve compatibility. They also made improvements in generated column's error reporting.
