如何从GORM结构模型生成SQL代码？

package main

import (
    "fmt"
    "gorm.io/driver/mysql"
    "gorm.io/gorm"
)

type User struct {
    ID   uint
    Name string
    Age  int
}

func main() {
    dsn := "user:password@tcp(127.0.0.1:3306)/database?charset=utf8mb4&parseTime=True&loc=Local"
    db, err := gorm.Open(mysql.Open(dsn), &gorm.Config{})
    if err != nil {
        panic("failed to connect database")
    }

    // 创建表结构
    err = db.AutoMigrate(&User{})
    if err != nil {
        panic("failed to create table")
    }

    // 插入数据
    user := User{Name: "Alice", Age: 20}
    result := db.Create(&user)
    if result.Error != nil {
        panic("failed to insert data")
    }

    // 查询数据
    var users []User
    result = db.Find(&users)
    if result.Error != nil {
        panic("failed to query data")
    }

    fmt.Println(users)
}
