Troubleshooting - Code differences between QODBC Desktop and QODBC Online

Problem Description:

I have an MS Access application using QODBC to connect to desktop QuickBooks. Can I use the QODBC Online driver to connect to QuickBooks Online without changing my MS Access code?  

Solution:

QODBC Online is the different product from QODBC Desktop driver. So you cannot use QODBC Desktop driver with QuickBooks Online. You need to use QODBC Online driver to connect to QuickBooks Online.

Most of the Tables, table columns, reports, report columns & report parameters in QuickBooks Desktop & Online are same. But not all the tables, reports & fields are available in QuickBooks desktop are available in QuickBooks Online. You might have to change few fields to match with QuickBooks Online. You need to refer QODBC Online reports/tables/fields & make changes in your code.

Please refer Difference between QODBC for QuickBooks Desktop and Online & make required changes in your code & use code with QODBC Online.
