To connect to Microsoft Dynamics CRM, 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 DynamicsCRM 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 CRM};User=myuseraccount;Password=mypassword;URL=https://myOrg.crm.dynamics.com/;CRM Version=CRM Online;;")
defer db.Close()
