SQL 语句发送到 TiDB 后首先会经过 parser，从文本 parse 成为 AST（抽象语法树），AST 节点与 SQL 文本结构是一一对应的，我们通过遍历整个 AST 树就可以拼接出一个与 AST 语义相同的 SQL 文本。

Given an absolute path for a file (Unix-style), simplify it. Or in other words, convert it to the canonical path.In a UNIX-style file system, a period . refers to the current directory. Furthermore, a double period .. moves the directory up a level. For more information, see: Absolute path vs rel...

If the seperator is a regular expression that contains capturing groups, the capturing groups will appear in the result as well.

简介： 问题描述 bug 触发条件如下： 优化器先选择了 where 条件中字段的索引，该索引过滤性较好； SQL 中必须有 order by limit 从而引导优化器尝试使用 order by 字段上的索引进行优化，最终因代价问题没有成功。 复现case 表结构 create table t
