    Just create different variables (db connections) using the Open function of sql library

    import "database/sql"
import _ "github.com/go-sql-driver/mysql"

func Connect() (*DB, *DB, *DB) {
    db1, err := sql.Open("mysql", "user1:password1@/dbname1")
    //check err
    db2, err := sql.Open("mysql", "user2:password2@/dbname2")
    //check err
    db3, err := sql.Open("mysql", "user3:password3@/dbname3")
    //check err
    return db1, db2, db3
}

    And you can use them further absolutely separately.
