 1. 解析sql生成语法树(不支持CREATE等语句，具体可以查看`core/astParser`文件)，支持单条sql语句
 2. 去除sql中的的注释(目前支持`--`,`/**/`类型注释)
 
+
+## 用法
+
+### 过滤注释 / sql分割
+
+``` javascript
+const dtFilter=require("dt-sql-parser").filter;
+const sql=`
+/*sttttttttart*/create table /*hhhhhhhh
+hhhhhh
+aaaaaa*/ sql_task_comment_test(id int comment 'id') comment 'sql test';
+    --eeeeeeeend
+`
+console.log(dtFilter.filterComments(sql))//过滤注释
+console.log(dtFilter.splitSql(sql));//分割sql
+```
+
+### 生成ast树
+``` javascript
+const dtFilter=require("dt-sql-parser").parser;
+const sql=`
+/*sttttttttart*/select userId as id,name /*hhhhhhhh
+hhhhhh
+aaaaaa*/ from user where isDeleted=0
+    --eeeeeeeend
+`
+console.log(dtFilter.parse(sql))//注意，目前只支持单条sql语句，所以需要自己调用sql分割一条一条处理！
+```
