MySQL

// default db
yiigo.DB().Get(&User{}, "SELECT * FROM user WHERE id = ?", 1)

// other db
yiigo.DB("other").Get(&User{}, "SELECT * FROM user WHERE id = ?", 1)

ORM(ent)

import "<your_project>/ent"

// default driver
client := ent.NewClient(ent.Driver(yiigo.EntDriver()))

// other driver
client := ent.NewClient(ent.Driver(yiigo.EntDriver("other")))

MongoDB

// default mongodb
yiigo.Mongo().Database("test").Collection("numbers").InsertOne(context.Background(), bson.M{"name": "pi", "value": 3.14159})

// other mongodb
yiigo.Mongo("other").Database("test").Collection("numbers").InsertOne(context.Background(), bson.M{"name": "pi", "value": 3.14159})

Redis

// default redis
conn, err := yiigo.Redis().Get(context.Background())

if err != nil {
    log.Fatal(err)
}

defer yiigo.Redis().Put(conn)

conn.Do("SET", "test_key", "hello world")

// other redis
conn, err := yiigo.Redis("other").Get(context.Background())

if err != nil {
    log.Fatal(err)
}

defer yiigo.Redis("other").Put(conn)

conn.Do("SET", "test_key", "hello world")

HTTP

// default client
yiigo.HTTPGet(context.Background(), "URL", yiigo.WithHTTPTimeout(5*time.Second))

// new client
c := yiigo.NewHTTPClient(*http.Client)
c.Get(context.Background(), "URL", yiigo.WithHTTPTimeout(5*time.Second))

Logger

// default logger
yiigo.Logger().Info("hello world")

// other logger
yiigo.Logger("other").Info("hello world")

SQL Builder

😊 为不想手写SQL的你生成SQL语句，用于 sqlx 的相关方法；

⚠️ 作为辅助方法，目前支持的特性有限，复杂的SQL（如：子查询等）还需自己手写

builder := yiigo.NewSQLBuilder(yiigo.MySQL)

• Query

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("id = ?", 1),
).ToQuery()
// SELECT * FROM user WHERE id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("name = ? AND age > ?", "shenghui0779", 20),
).ToQuery()
// SELECT * FROM user WHERE name = ? AND age > ?
// [shenghui0779 20]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.WhereIn("age IN (?)", []int{20, 30}),
).ToQuery()
// SELECT * FROM user WHERE age IN (?, ?)
// [20 30]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Select("id", "name", "age"),
    yiigo.Where("id = ?", 1),
).ToQuery()
// SELECT id, name, age FROM user WHERE id = ?

// SELECT DISTINCT name FROM user WHERE id = ?
// [1]

    yiigo.Having("user_id = ?", 1),
).ToQuery()
// SELECT user_id, COUNT(*) AS total FROM address GROUP BY user_id HAVING user_id = ?

// (SELECT * FROM user_0 WHERE id = ?) UNION (SELECT * FROM user_1 WHERE id = ?)
// [1, 2]

builder.Wrap(

    UnionAll(wrap1),
).ToQuery()
// (SELECT * FROM user_0 WHERE id = ?) UNION ALL (SELECT * FROM user_1 WHERE id = ?)
// [1, 2]

    Union(

• Insert

// INSERT INTO user (name, age) VALUES (?, ?)
// [yiigo 29]

builder.Wrap(yiigo.Table("user")).ToInsert(yiigo.X{
    "name": "yiigo",
    "age":  29,
})
// INSERT INTO user (name, age) VALUES (?, ?)
// [yiigo 29]

• Batch Insert

type User struct {

    },
    {
        Name: "yiigo",
        Age:  29,
    },

// INSERT INTO user (name, age) VALUES (?, ?), (?, ?)
// [shenghui0779 20 yiigo 29]

builder.Wrap(yiigo.Table("user")).ToBatchInsert([]yiigo.X{

        "age":  29,
    },
})
// INSERT INTO user (name, age) VALUES (?, ?), (?, ?)

• Update

type User struct {
    Name   string `db:"name"`
    Age    int    `db:"age"`
    Phone  string `db:"phone,omitempty"`
}

builder.Wrap(
    Table("user"),

    Age:  29,
})
// "UPDATE user SET name = ?, age = ? WHERE id = ?"
// [yiigo 29 1]

builder.Wrap(

).ToUpdate(yiigo.X{
    "name": "yiigo",
    "age":  29,

// UPDATE user SET name = ?, age = ? WHERE id = ?
// [yiigo 29 1]

builder.Wrap(

    yiigo.Where("id = ?", 1),
).ToUpdate(yiigo.X{
    "price": yiigo.Clause("price * ? + ?", 2, 100),

• Delete

builder.Wrap(
