To connect to Marketo, 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 Marketo 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 Marketo};Schema=REST;RESTEndpoint=https://MyMarketoUrl/rest;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;;")
defer db.Close()
