摘　　要：LabWindows/CVI是一款完全基于标准C语言的面向计算机测控领域的优秀软件开发环境。针对LabWindows/CVI本身不具备数据库访问功能的不足,总结并实现了三种能够在CVI环境下访问外部数据库的方法。详细阐述了Microsoft ADO、NI SQL Toolkit以及DatabaseAssistant三种方法在CVI环境下访问数据库的具体途径,通过实验对三种方法的数据库访问性能进行了比较,实验结果表明在CVI中DatabaseAssistant具有最快的数据库访问速度。LabWindows/CVI is an excellent software development environment based completely on the standard C language for the computer measurement and control.To address the issue that LabWindows/CVI can not access database by itself,this paper summarizes and realizes the three methods,the Microsoft ADO、the NI SQL Toolkit and the DatabaseAssistant,which can achieve to access external database in the CVI environment.The paper explains sufficiently how to access the database in CVI through the above three methods,and their performance of database access is compared through the experiments.Experimental results show that the DatabaseAssistant method has the fastest access speed in CVI.
