// create a new DbMap instance db, err := sql.Open("mysql", "user:password@tcp(127.0.0.1:3306)/mydatabase") if err != nil { log.Fatal(err) } defer db.Close() // create a new DbMap instance passing in a pointer to the database connection dbmap := &gorp.DbMap{Db: db, Dialect: gorp.MySQLDialect{}} // create a new struct representing a database table type User struct { Id int64 Name string Email string Active bool } // create the table in the database using DbMap.CreateTable err = dbmap.CreateTableIfNotExists(&User{}) if err != nil { log.Fatal(err) } // insert a new row into the table user := &User{Name: "John Doe", Email: "[email protected]", Active: true} err = dbmap.Insert(user) if err != nil { log.Fatal(err) } // query the table using DbMap.Select var users []User _, err = dbmap.Select(&users, "SELECT * FROM users WHERE active = ?", true) if err != nil { log.Fatal(err) }In the example above, we first create a new DbMap instance by passing in a pointer to a MySQL database connection. We then create a struct representing a user in our database and use the DbMap.CreateTable method to create the table if it doesn't exist. Next, we insert a new user into the table using the DbMap.Insert method. Finally, we query the table using the DbMap.Select method to retrieve all active users. The package library is likely a utilities/library for database object-relational mapping with Go.
