这篇文章首先会回顾一下整个 SQL 的执行过程,用来说明为什么要范围计算,最后从源码的角度讲解一下 析取范式 DNF (disjunctive normal form) 和 合取范式 CNF (conjunctive normal form) 是如何转化为范围区间。 优化过程解析 TiDB 在进行表扫描前会对查询条件,也就是 Selection 算子的过滤条件化简, 转为区间扫描。
The value is a string of case-sensitive characters and must begin with a letter. The value ranges from 1 to 32. To avoid confusion, do not use "all" as the name of a time range. starting-time, ending-time Specify the start time and end time of a time range. The format is hh:...
