Parser - A MySQL Compatible SQL Parser

The goal of this project is to build a Golang parser that is fully compatible with MySQL syntax, easy to extend, and high performance. Currently, features supported by parser are as follows:

  • Highly compatible with MySQL: it supports almost all features of MySQL. For the complete details, see parser.y and hintparser.y.
  • Extensible: adding a new syntax requires only a few lines of Yacc and Golang code changes. As an example, see PR-9.
  • Good performance: the parser is generated by goyacc in a bottom-up approach. It is efficient to build an AST tree with a state machine.

Future

  • Support more MySQL syntax
  • Optimize the code structure, make it easier to extend
  • Improve performance and benchmark
  • Improve the quality of code and comments
