Using DSNLess Connections To MySQL

To create linked Access tables to a remote server, one of the methods commonly used is to create a DSN on every computer that needs to connect. The DSN defines the server's IP Address, port, database name, user and password information and is created through the Administration tools of the Control Panel. This process can be time-consuming.

The DSNLess method uses VBA code and the construction of a connect string to accomplish the same task with no need to create a DSN on each user's PC.

Before you run the code, you need to have all the information mentioned above that would normally be required for a DSN. In addition, on the client computers, you must install the MySQL ODBC connector software and know the version so that it can be specified in your connect string.

Here's an example of connecting to a MySQL database where you know the table names.
