To connect to Workday, 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 Workday 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 Workday};User=myuser;Password=mypassword;Tenant=mycompany;Host=https://wd3-impl-services1.workday.com;")
defer db.Close()
