GoORM

GoORM is an ORM for Go. It lets you map Go structs to tables in a database. It's intended to be very lightweight, doing very little beyond what you really want. For example, when fetching data, instead of re-inventing a query syntax, we just delegate your query to the underlying database, so you can write the "where" clause of your SQL statements directly. This allows you to have more flexibility while giving you a convenience layer. But GoORM also has some smart defaults, for those times when complex queries aren't necessary.

Installing GoORM

go get github.com/astaxie/goorm

How do we use it?

Open a database

orm := goorm.NewORM("127.0.0.1", "3306", "test", "xiemengjun", "123456", "utf8")

Change Database

orm.SelectDb("test2")

Model a struct after a table in the db

type Person struct {
	Id int64
	Name string
	Age int64
}

Create an object and save it

var someone Person
someone.Name = "john"
someone.Age = 20

orm.Save(&someone)

Fetch a single object

var person1 Person
orm.Get(&person1, "id = ?", 3)

var person2 Person
orm.Get(&person2, 3) // this is shorthand for the version above

var person3 Person
orm.Get(&person3, "name = ?", "john") // more complex query

var person4 Person
orm.Get(&person4, "name = ? and age < ?", "john", 88) // even more complex

Fetch multiple objects

var bobs []Person
err := orm.GetAll(&bobs, "name = ?", "bob")

var everyone []Person
err := orm.GetAll(&everyone, "") // use empty string to omit "where" clause

Saving new and existing objects

person2.Name = "Jack" // an already-existing person in the database, from the example above
db.Save(&person2)

var newGuy Person
newGuy.Name = "that new guy"
newGuy.Age = 27

db.Save(&newGuy)
// newGuy.Id is suddenly valid, and he's in the database now.
