复现代码如下
type User struct {
ID uint `gorm:"primaryKey"`
Username string `gorm:"unique;not null"`
Email string `gorm:"unique;not null"`
Password string
ReferrerID *uint
CreatedAt time.Time
UpdatedAt time.Time
Referrer *User `gorm:"foreignKey:ReferrerID"`
}
func main() {
dsn := "user= password= TimeZone=Asia/Shanghai"
db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{
Logger: logger.Default.LogMode(logger.Error),
NamingStrategy: schema.NamingStrategy{
TablePrefix: "test.",
},
})
if err != nil {
panic("open error:" + err.Error())
}
user1 := new(User)
db.First(&user1, 1)
fmt.Println(user1)
}
第一次查询没有问题,但如果随后再运行一次则会报错,报错结果如下
ERROR: prepared statement "stmtcache_1bf13e07b440e6435429cc5d947ef4bea4959aebb2634e29" already exists (SQLSTATE 42P05)
