golang中使用gorm连接mysql操作

package main

import (
    "fmt"
    "github.com/jinzhu/gorm"
    _ "github.com/go-sql-driver/mysql"
    "time"
)

type User struct {
    UserId int  `gorm:"primary_key"`
    Phone string
    WxopenId string
    Tcreate *time.Time
    Tprocess *time.Time
    Balance int
    Src string
    Level int

}
func main() {
    //连接数据库
    db,err := gorm.Open("mysql","root:[email?protected](127.0.0.1:3306)/dbname?charset=utf8")
    //一个坑，不设置这个参数，gorm会把表名转义后加个s，导致找不到数据库的表
    db.SingularTable(true)
    defer db.Close()
    if err != nil {
        panic(err)
    }
    var user User
    fmt.Println(db.HasTable(user))
    
    var phone="12345678900"
    //条件查询
    err = db.Where("phone = ?",phone).Find(&user).Error
    if err != nil {
        fmt.Println(err)
    }
    
    fmt.Println(user.UserId)
    //把查询出来的一条数据删除
    err=db.Delete(&user).Error
    if err !=nil{
        fmt.Println(err)
    }

}
