摘要
在很多工程项目中,数据库的数据处理通常都是使用标准的SQL语句完成的。但标准的SQL语句在复杂的数据处理中却存在着诸多不足。正则表达式是一种非常重要和有效的字符串匹配模式,将其应用于SQL语句中,具有强大的数据处理功能。通过一个学员信息管理系统中使用的基于正则表达式的数据处理应用表明,该表达式不仅可以实现复杂的操作,而且降低了SQL语句的复杂程度,简化了对出错语句的修改工作。
Data processing is usually accomplished with the standard SQL statement in many projects.However,the standard SQL statements have many disadvantages while processing the complex data.The regular expression is a very important and effective string search mode.It has powerful data processing ability when being applied to the SQL statement.The application of data processing was introduced based on the regular expression in a student information management system.It not only accomplished the complex data processing,but also reduced the complexity of the SQL statement,and simplified the modification of the error SQL statements.
