To connect to Microsoft Dynamics 365, you can use either a DSN or an ODBC connection string. Both of these methods use the sql package's Open function.

Connect to a DSN

To connect using a DSN:

db, _ := sql.Open("odbc", "DSN=CData Dynamics365 Sys;")
defer db.Close()

Provide a Driver Connection String

To connect using an ODBC connection string:

db, _ := sql.Open("odbc", "DRIVER={CData ODBC Driver for Microsoft Dynamics 365};OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;;")
defer db.Close()
