-dt-sql-parser 是一个基于 [ANTLR4](https://github.com/antlr/antlr4) 开发的， 针对大数据领域的 `SQL Parser` 项目。通过[ANTLR4](https://github.com/antlr/antlr4) 默认生成的 Parser、Visitor 和 Listener 对象，我们可以轻松的做到对 SQL 语句的`语法检查`（Syntax Validation）、`词法分析`（Tokenizer)、 `遍历 AST` 节点等功能。此外，还提供了几个辅助方法, 例如 SQL 切分（Split）、过滤 SQL 语句中的 `--` 和 `/**/` 等类型的注释。
