To connect to ServiceNow, 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 ServiceNow 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 ServiceNow};OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;;")
defer db.Close()
