Hi, If you are working on a Windows machine I would like you to first perform a test connection on your DSN to ensure you could access the Denodo view using ODBC connection. Have a look at [DSN configuration for ODBC connections to VDP](https://community.denodo.com/kb/view/document/DSN%20configuration%20for%20ODBC%20connections%20to%20VDP?category=Northbound+Connections) Also check if you have the VDP server in the running status and the underlying Denodo views are still available in VDP Admin Tool. I hope this helps you!

Hi, When I need to get a specific number of results, I usually add the **LIMIT** clause to the end of my query. For example: ``` SELECT * FROM customers LIMIT 10; ``` When I have a problem executing a view and I am not sure where is the error, I follow these steps to pinpoint the reason: 1. I get the query executed in the Denodo VDP Server by reading the vdp-requests.log. 2. Once I have the query throwing the error, I execute it in the VQL Shell of the VDP Admin tool. 3. I annalyze the execution trace to see which is the first node with error. If with that you are still not able to solve your problem and you have a user with access to the Denodo Support site (http://support.denodo.com), I would recommend you to raise a support case and the Denodo Support team will help you to find the solution. Hope this helps!
