    • Methods, systems, and articles for receiving, by a computing device, execution results of a plurality of query language expressions are described herein. In various embodiments, the plurality of query language expressions may be concurrently executed, and the receiving may be contemporaneous with production of the execution results. Also, in various embodiments, the computing device may store a result item of the execution results for at least a first of the query language expressions in a memory block allocated exclusively for the first of the query language expressions while the first of the query language expressions is being executed, or in a result handle associated with the first of the query language expressions.
    • 本文描述了由计算设备接收多个查询语言表达式的执行结果的方法,系统和文章。 在各种实施例中,可以同时执行多个查询语言表达,并且接收可以同时生成执行结果。 此外,在各种实施例中,计算设备可以将至少第一查询语言表达式的执行结果的结果项存储在专门针对第一查询语言表达式分配的存储器块中,而第一查询语言表达式 正在执行,或在与第一个查询语言表达式相关联的结果句柄中。

    • The present invention provides a method for transforming a concept-based query into SQL query statements, comprising the steps of: transforming inputted concept-based queries into logic rules; checking validity of the logic rules; optimizing the valid logic rules; and translating the logic rules into SQL query statements in accordance with the optimization result. The present invention further provides corresponding transformation engine, database query system and computer program product. The present invention facilitates people to use more descriptive query language to query data stored in relational database. Furthermore, the present invention can automatically generate the correct and efficient SQL query statements so that people's efforts to deal with complex data model are saved significantly.
    • 本发明提供了一种将基于概念的查询转换成SQL查询语句的方法,包括以下步骤:将输入的基于概念的查询转换成逻辑规则; 检查逻辑规则的有效性; 优化有效逻辑规则; 并根据优化结果将逻辑规则转换为SQL查询语句。 本发明还提供了相应的转换引擎,数据库查询系统和计算机程序产品。 本发明便于人们使用更具描述性的查询语言来查询存储在关系数据库中的数据。 此外,本发明可以自动生成正确和有效的SQL查询语句,从而大大节省了人们处理复杂数据模型的努力。
