对数据库中SQL语句的优化技术进行研究——对LECCO SQL Expert的分析与研究

SQL Statement Optimization Study for Database --CCO SQL Expert Analysis and Research

对于计算机数据库SQL语句的优化问题，有的的优化专家认为，通过将性能相对低下的SQC语句优化使其转化为目的相同的性能优异的SQL语句，可以得到近40％的系统性能的提升，一直以来，这是计算机研究者热衷的问题。对人工智能自动SQL优化而言，通常指的是通过使用人工智能技术，自动的对SQL语句进行重新输入，从而将数据库中SQL语句优化为最优的等效SQL语句。

Some optimization experts believe that database can get nearly 40% system performance by optimizing SQL statements to high performance of SQL statements about the problem of database SQL statement optimization,which have always been keen on by computer researchers. Through artificial intelligence to automatically optimize on the SQL is re-inputing of the SQL statement for get the optimal SQL statement with the same effect.
