在Lab Windows／CVI中实现数据库访问的两种方法

Two Methods of Realizing Database Access in LabWindows/CVI

由于LabWindows／CVI中没有提供与通用数据库直接接口的方法，而在绝大多数测试软件中都存在大量数据操作，所以在LabWindows／CVI环境下操作数据库是测试软件开发者经常面对的问题。此问题可以通过以下两种方法解决：基于ADO技术的数据库访问；采用LabWindows／CVISQLToolkit工具包的数据库访问。首先，通过实例介绍了上述两种方法的使用方法，然后通过实际操作测试，比较了两种方法在功能、效率、通用性等方面的优劣。

The testing software programmers are constantly faced up with some problems that operating database under LabWindows / CVI enviromnent because LabWindows / CVI does not provide a direct interface to connect general database while a large number of data manipulation happens in the most of testing software. This problem could be solved by the following two methods： the ADO technology based database aeeess; the LabWindows / CVI SQLToolkit used for database access. This paper introduces how to use the above two methods at first , and then compares the merits and demerits of the two methods in the function, efficiency and versatility.
