To connect to SAP Business One, 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 SAPBusinessOne 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 SAP Business One};Url=http://localhost:50000/b1s/v1;User=username;Password=password;CompanyDB=dbname;;")
defer db.Close()
