Second, we rewrite the simple path expression into SQL statements. We research the different rewriting techniques for the different mapping nodes and different condition in where clause. For the query optimizing, we propose the path index based on the notion of node equivalence which is computed by bi-simulation algorithm.

第二步把简单路径表达式通过DTD字典重写为SQL语句,主要研究了对于SPE上的结点由于其映射的结点类型不同而进行不同的重写处理,同时研究了对于带有条件的查询在各种情况下的重写过程(如返回路径和条件路径不在一条路径上、多条件查询等)。

The optimization methods of database SQL query were studied and some available query optimization Methods were given out as follows: The incompatible data type should avoid to be used; More redundancy search parameters should be given as join condition in join query; In some condition, the number of note hitted to target was estimated by optimizing implement using the average density; Some other maths operating symbol should avoid to be used as condition parameters in WHERE clause; Some operating symbol and its sentence should avoid to be used also; When the cluster function was used,the WHERE clause should be paied attention to more,and so on.

作者单位:(重庆工学院商贸信息学院,重庆 400050)摘要:数据库SQL查询语句的优化,须注意:避免使用不兼容数据类型;连接查询中应多给连接条件提供一些冗余的搜索参数;某种条件下优化器只能使用其平均密度以估计命中的记录数;避免对WHERE子句中条件参数使用其它数学操作符;避免使用某些操作符及相应语句;聚簇函数的使用应注意WHERE子句。
