When you configure a DSN, it is also stored in the Windows registry as shown in Figure 4. If you install another driver, an entry is added to the registry under ODBCINST.INI.Īnd we use these drivers to set up data source names or DSNs. Figure 4. The list of ODBC drivers and DSNs are stored in the Windows registry. This list has a counterpart in the Windows registry as seen in Figure 4 below. Figure 3. The list of ODBC drivers is displayed in the ODBC Data Source Administrator. We can also see installed ODBC drivers in this app as shown in Figure 3 below. That’s the driver manager in Windows in a file called odbc32.dll. Figure 2. The ODBC driver manager (odbc32.dll) in Windows. Here, we can see our ODBC driver manager in the About tab. To connect to the ODBC data source, we use the ODBC Data Source Administrator. So, all you need to do is to install ODBC drivers and configure data sources. The driver manager for Windows is also pre-configured. You don’t need to download and install it unless you’re using an older Windows operating system. Starting with Windows XP and Windows Server 2003, the driver manager for Windows is preinstalled. ODBC driver manager for Windows already exists in modern Windows machines. Installing and Configuring an ODBC Driver Manager on Windows Let’s consider how to install the ODBC driver manager depending on the operating system. You can start using the ODBC driver manager after installing and configuring it. This is done uniformly regardless of the database product Provides an easy way to do common database tasks from your app.So, the ODBC driver manager performs the following: The database will then return the results. Then, they are submitted from the driver manager to the ODBC driver. The application can now submit SQL statements through the driver manager. Finally, the database responds by returning connection success or failure.The security credentials are passed from the connection string used by the application. The connect function in the driver establishes a connection to the database.When the driver is loaded, the manager calls an SQLConnect or SQLDriverConnect function in the ODBC driver.Then, the driver manager loads the correct ODBC driver based on the connection string.First, the app connects to a certain database using a connection string or an ODBC data source name.To put it simply, this is what happens when your application starts connecting to your database: The ODBC driver manager manages communication between apps and ODBC drivers. To explain what this driver manager is, take a look at the ODBC architecture in Figure 1. Installing and Configuring an ODBC Driver Manager on macOS.
