labwindows cvi如何与SQL数据库连接

1.在ODBC中配置数据源

2.ConnectHandle=DBConnect ("DSN=CVILocalUID=saPWD=123")

ActivateHandle= DBActivateSQL (ConnectHandle, "select * from 标志位表")

while(DBFetchNext(ActivateHandle)==DB_SUCCESS)

{

DBGetColVariant (ActivateHandle, 2, &TempInt)

CA_VariantConvertToType (&TempInt, CAVT_INT, &StartMarkInt)

}

DBDeactivateSQL (ActivateHandle)

DBDisconnect (ConnectHandle)

就是编辑文件，修改里面你认为需要修改的内容，一般要修改下面的这几行：

$oc_db_server = 'localhost'

$oc_db_name = 'mobile'

$oc_db_user = 'admin'

$oc_db_pass = 'ma2kivu'
