```go package main import ( "fmt" "github.com/jinzhu/gorm" ) import _ "github.com/go-sql-driver/mysql" type UserInfo struct { Id int `gorm: "primary_key;AUTO_INCREMENT:number"` UserName string `gorm:"column:name"` Phone string } func main() { db, _ := gorm.Open("mysql", "root:123456@(127.0.0.1:3306)/gormstudy?charset=utf8&parseTime=True&loc=Local") defer db.Close() db.SingularTable(true) has := db.HasTable(&UserInfo{}) if !has { db.AutoMigrate(&UserInfo{}) fmt.Println("创建表") } // 添加数据 /* p1 := UserInfo{UserName:"abc1",Phone:"1231"} p2 := UserInfo{UserName:"abc2",Phone:"1232"} p3 := UserInfo{UserName:"abc3",Phone:"1233"} p4 := UserInfo{UserName:"abc4",Phone:"1234"} db.Create(&p1) db.Create(&p2) db.Create(&p3) db.Create(&p4)*/ // 删除Username为abc2的记录 user :=&UserInfo{UserName:"abc2"} db.Delete(user) } ```
