语法树打印

##结果集信息

可以通过设置选项--query-print=1或者--enable-query-print来启用打印语法树的功能, 同样的,它与其它enable开头的选项是互斥的,不能同时设置,开启之后,再连接goInception,执行返回的结果集所包括的列如下:

  1. ID:这个用来表示当前语句的一个序列值。
  2. STATEMENT:这个列用来存储当前被分析的SQL语句。
  3. ERRLEVEL:这个列用来存储当打印遇到问题时,错误的级别,与审核结果集中的ERRLEVEL意义相同。
  4. QUERY_TREE:这个列就是对当前语句的分析结果,格式为JSON字符串。
  5. ERRMSG:这个列与上面的ERRLEVEL对应,当出错时,这里存储分析过程中所有的错误信息,与审核结果集中的同名列意义相同。

###示例

SQL语句:

INSERT INTO t
            (sno,
             name)
SELECT sno,
       name
FROM   t alias_t
WHERE  sno = (SELECT sno + 1
              FROM   my
              WHERE  name LIKE "%zhufeng%"
                     AND sno > '10010'
                     AND name = alias_t.name)
ORDER  BY name
LIMIT  100, 10;

返回的结果对应的Json可视化的query_tree如下:

{
  "text": "insert into t (sno,name)\n        select sno, name from t alias_t\n        where sno=(\n                select sno+1 from my\n                where\n                name like \"%zhufeng%\" and\n                sno > '10010' and\n                name=alias_t.name\n        )\n        order by name\n        limit 100, 10",
