Motivation In the development of traditional database software, the automatic sequence generation technology is a basic requirement. All kinds of databases have provided corresponding support for this requirement can include tables, options, ordering items, grouping items, aggregation functions, pagination information, query conditions and placeholders that may be revised. Query Optimization It merges and optimizes includes select items, table information, sharding conditions, auto‐increment primary key information, Order By information, Group By information, and pagination information (Limit, Rownum and Top).
