Aorm又进步了，目前已支持MySQL,MSSQL,Postgres,Sqlite3，并且支持子查询

id, errInsert := aorm.Use(db).Debug(true).Insert(&Person{
    Name:       null.StringFrom("Alice"),
    Sex:        null.BoolFrom(false),
    Age:        null.IntFrom(18),
    Type:       null.IntFrom(0),
    CreateTime: null.TimeFrom(time.Now()),
    Money:      null.FloatFrom(100.15),
    Test:       null.FloatFrom(200.15987654321987654321),
})
if errInsert != nil {
    fmt.Println(errInsert)
}
fmt.Println(id)
