In Oracle, it's possible to insert literal or concatenate 2 or more charater strings or SQL result output together.

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。

This is a very common construct in SQL.

Through the utilization of advanced computer technology, multimedia technologies, simulation technique, profited from the design concept of the Simens TIA, with the aid of Tomcat, Microsoft SQL Server, WinCC Web Navigator, SIMIT, this system achieved the crasis of the industrial ethernet directed net and information network, constructed a distance laboratory with remote control, monitoring, management as one, and used the JSP technical to complete the distance laboratory website.

该系统运用了先进的计算机技术、多媒体技术、仿真技术，借鉴西门子全集成自动化的设计思想，通过使用Tomcat软件、Microsoft SQL Server软件、西门子WinCC Web Navigator软件、SIMIT仿真软件等，实现了工业以太网控制网络与信息网络的融合，构建了一个集远程控制与监控为一体的远程实验室，并使用JSP技术设计完成远程实验室网站，实现了实验室信息的共享。

Comparing with Daikon,the method has two excellent features.Firstly,it is better expansible based on the RDBMS technology;Secondly,discovering of program invariants can be accomplished by the function of SQL query based on the technology of relational database which can detect the program invariants in a nimble way.

该方法和Daikon等现有的程序不变量检测工具检测方法比较具有明显的特色和优势：第一，基于关系数据库技术，具有良好的可扩展性；第二，使用SQL条件查询功能实现非函数依赖程序不变量检测，检测方法具有很好的灵活性。
