Installation

go get github.com/uptrace/bun
go get github.com/uptrace/bun/dialect/sqlitedialect

Quickstart

First you need to create a sql.DB. Here we using the SQLite3 driver.

import _ "github.com/mattn/go-sqlite3"

sqldb, err := sql.Open("sqlite3", ":memory:?cache=shared")
if err != nil {
	panic(err)
}

And then create a bun.DB on top of it using the corresponding SQLite dialect:

import (
	"github.com/uptrace/bun"
	"github.com/uptrace/bun/dialect/sqlitedialect"
)

db := bun.NewDB(sqldb, sqlitedialect.New())

Now you are ready to issue some queries:

type User struct {
	ID	 int64
	Name string
}

user := new(User)
err := db.NewSelect().
	Model(user).
	Where("name != ?", "").
	OrderExpr("id ASC").
	Limit(1).
	Scan(ctx)

The code above is equivalent to:

query := "SELECT id, name FROM users AS user WHERE name != '' ORDER BY id ASC LIMIT 1"

rows, err := sqldb.QueryContext(ctx, query)
if err != nil {
	panic(err)
}

if !rows.Next() {
    panic(sql.ErrNoRows)
}

user := new(User)
if err := db.ScanRow(ctx, rows, user); err != nil {
	panic(err)
}

if err := rows.Err(); err != nil {
    panic(err)
}

Basic example

First we need to load some data for our basic example. To provide initial data we are going to use Bun fixtures:

import "github.com/uptrace/bun/dbfixture"

// Register models for the fixture.
db.RegisterModel((*User)(nil), (*Story)(nil))

// WithRecreateTables tells Bun to drop existing tables and create new ones.
fixture := dbfixture.New(db, dbfixture.WithRecreateTables())

// Load fixture.yaml which contains data for User and Story models.
if err := fixture.Load(ctx, os.DirFS("."), "fixture.yaml"); err != nil {
	panic(err)
}

The fixture.yaml looks like this:

- model: User
  rows:
    - _id: admin
      name: admin
      emails: ['admin1@admin', 'admin2@admin']
    - _id: root
      name: root
      emails: ['root1@root', 'root2@root']

- model: Story
  rows:
    - title: Cool story
      author_id: '{{ $.User.admin.ID }}'

To select all users:

users := make([]User, 0)
if err := db.NewSelect().Model(&users).OrderExpr("id ASC").Scan(ctx); err != nil {
	panic(err)
}

To select a single user by id:

user1 := new(User)
if err := db.NewSelect().Model(user1).Where("id = ?", 1).Scan(ctx); err != nil {
	panic(err)
}

To select a story and the associated author in a single query:

story := new(Story)
if err := db.NewSelect().
	Model(story).
	Relation("Author").
	Limit(1).
	Scan(ctx); err != nil {
	panic(err)
}

To select a user into a map:

m := make(map[string]interface{})
if err := db.NewSelect().
	Model((*User)(nil)).
	Limit(1).
	Scan(ctx, &m); err != nil {
	panic(err)
}

To select all users scanning each column into a separate slice:

var ids []int64
var names []string
if err := db.NewSelect().
	ColumnExpr("id, name").
	Model((*User)(nil)).
	OrderExpr("id ASC").
	Scan(ctx, &ids, &names); err != nil {
	panic(err)
}
