How to use MS Access as Middleware with QODBC

Problem Description:

Any errors related to the driver and custom software or packaged software that does not work properly with QODBC.Example, Prepared Statements in JDBCODBCDriver.

Sample
 Connection qbConn = null;
 PreparedStatement psStmt = null;
 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
 con = DriverManager.getConnection("jdbc:odbc:QRemote")
 cusPstmt = qbConn.prepareStatement("insert into ItemSubtotal (Name,ItemDesc,IsActive) values (?,?,?)");

When I execute the above code at line 5, it throws an error as below.

java.sql.SQLException: [Microsoft][ODBC Driver Manager] Driver does not support this function

Few of the features of ODBC are not supported on QODBC; what is the workaround?

Solutions:

You are using a function/feature which is not supported by the QODBC driver, or maybe it's not a standard ODBC call. To overcome the issue, you can use MS-Access as middleware, i.e. Create linked tables in MS-Access, create a DSN of your ms access database, connect your application to MS-Access DSN.

Your application will connect 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.

Assuming you have created an MS Access file and have created linked tables.

Let us create an MS Access DSN that will point to the Access database file which we had 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"

 

 

2) Choose "Microsoft Access Driver (*.mdb, *.accdb)" & click on "Finish" button.

 

3) Enter DSN name & description & click on select.

 

4) Provide MS Access database file location, which we created earlier & click on "OK".

 

5) Click on "OK" to save DSN.

 

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.

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.

For 64-bit : Start>>All Programs>> QODBC Driver for use with QuickBooks>> Configure QODBC Data Source 64-bit>>Go To "System DSN" Tab>>Click on "Add"
