1、安装
go get -u gorm.io/gorm
go get -u gorm.io/driver/sqlite //sqlite 数据库
2、使用示例（sqlite）
package main
import (
"gorm.io/driver/sqlite"
"gorm.io/gorm"
)
type Product struct {
gorm.Model
Code string
Price uint
}
func main() {
db, err := gorm.Open(sqlite.Open("test.db"), &gorm.Config{})
if err != nil {
panic("failed to connect database")
}
// Migrate the schema
db.AutoMigrate(&Product{})
// 新增
db.Create(&Product{Code: "D42", Price: 100})
// 查询
var product Product
db.First(&product, 1) // find product with integer primary key
db.First(&product, "code = ?", "D42") // find product with code D42
// 更新
db.Model(&product).Update("Price", 200)
db.Model(&product).Updates(Product{Price: 200, Code: "F42"}) // non-zero fields
db.Model(&product).Updates(map[string]interface{}{"Price": 200, "Code": "F42"})
// 删除
db.Delete(&product, 1)
}
