How to use MS Access as Middleware with QODBC

Problem Description:

When using Prepared Statements with QRemote driver, then it throws an error called ODBC driver not supported. How can I use Prepared Statements with QODBC/QRemote?

Solutions:

You may be using a function/feature which is not supported by the ODBC driver. You can use MS-Access as middleware, i.e. Create linked tables in MS-Access, connect your application to MS-Access, MS-Access has a linked table connecting to QRemote or QODBC.

First, you need to create the linked table in MS Access. Please refer to the mentioned article for creating the linked table in MS Access.

For 32-bit MS Access: How to Configure QODBC to Work With 32-bit MS Access

For 64-bit MS Access: How to Configure QODBC to Work With 64-bit MS Access

Please Note 64-bit MS Access article contains information about the Import table; Please choose the "Link to the data source by creating a linked table" option for creating the linked table.

Now we are creating MS Access DSN that points to the Access database file which we created in the above steps. Please follow the below steps for creating MS Access DSN.

1) Please create a new MS Access DSN from:
Start>>All Programs>> QODBC Driver for use with QuickBooks>> Configure QODBC Data Source>>Go To "System DSN" Tab>>Click on "Add"

6) Newly created DSN is available in the DSN list.

7) Now, we will use this DSN as a Middleware. We will test this DSN with our QODBC Test Tool application. Please open QODBC Test Tool from:
Start>>All Programs>> QODBC Driver for use with QuickBooks>>QODBC Test Tool

 

8) Please select newly created DSN from the dropdown list & click on "Connect".

 

9) You can see we are able to connect to MS Access DSN from QODBC Test Tool. Please write your SQL statement & click on "Run".

 

You can see we are able to fetch data with MS Access DSN from QODBC Test Tool. 


Note: 
 QODBC Support Wizard is used to test QODBC SQL queries only and is not a development tool; you should be able to use the MS Access DSN ("Access Middleware") on your application.
