附件的例子中,如果这个serial(作为Primary Key)已经存在于表格中,继续写入将会出错。
有什么办法,能使新数据将表格中同一个serial的旧数据覆盖掉?
谢谢!
另外,SQL数据库中有个叫uniqueidentifier的数据类型,即使有这个Toolset,LabVIEW也不认识它。不知道大家碰到过这样的问题没有,该如何才能在我的LabVIEW程序中存储和读取这个数据类型?

你可以在SQL语言中选择修改数据操作(Update)。
uniqueidentifier在SQL Toolkit 5.0中是不支持的,在新版的Database Connectivity Toolset 才可以
