// Example 2
q := *sqlb.SQL("select * from users").
	Where(sqlb.In("age", []string{"76", "80"})).
	Or("email", "[e-mail]").
	Where(sqlb.Between("salary", []float64{5000, 5900})).
	Or(sqlb.NotIn("role", []string{"admin", "driver"})).
	GroupBy("id", "age").
	Having(sqlb.NotEq("email", "[e-mail]")).
	Or(sqlb.NotIn("item", []int{0, 1})).
	Limit(90).
	Offset(7).
	OrderBy("id").
	Build()

# output

Insertion

q := sqlb.Insert("users").Value("email", "[e-mail]").
	Value("age", 10).
	Return("id").
	Build()

# output
insert into users (email,age) values([e-mail],10) returning id

Update

q := sqlb.Update("users").Set("email", "[e-mail]").
	Set("age", 10).
	Where("id", 2).
	Or(sqlb.NotIn("item", []int{0, 1})).
	Return("updated_at").
	Build()

# output
update users set email=[e-mail],age=10 where id=2 or item not in (0,1) returning updated_at;

Delete

q := sqlb.Delete("users").
	Where("id", 2).
