设置 RaiseErrorOnNotFound 不生效

[yoongadev]

版本：v1.25.12

参考 #6105 中的方法进行设置后，使用 Find 查询依然无法触发 ErrRecordNotFound 错误

        gormDB, err := gorm.Open(mysql.New(mysql.Config{Conn: db}), &gorm.Config{SkipDefaultTransaction: true, QueryFields: true})
	if err != nil {
		log.Fatal(err)
		return
	}
	gormDB.Statement.RaiseErrorOnNotFound = true
	// gormDB = gormDB.WithContext(gormDB.Statement.Context)

        // err is ErrRecordNotFound
        err := gormDB.Where("price > 100").Find(&r).Error

当取消注解 gormDB = gormDB.WithContext(gormDB.Statement.Context) 后可以正常生效。

func (db *DB) getInstance() *DB {
	if db.clone > 0 {
		tx := &DB{Config: db.Config, Error: db.Error}

		if db.clone == 1 {
			// clone with new statement
			tx.Statement = &Statement{
				DB:                   tx,
				ConnPool:             db.Statement.ConnPool,
				Context:              db.Statement.Context,
				Clauses:              map[string]clause.Clause{},
				Vars:                 make([]interface{}, 0, 8),
				SkipHooks:            db.Statement.SkipHooks,
			}
			if db.Config.PropagateUnscoped {
				tx.Statement.Unscoped = db.Statement.Unscoped
			}
		} else {
			// with clone statement
			tx.Statement = db.Statement.clone()
			tx.Statement.DB = tx
		}

		return tx
	}

	return db
}

参考上面源码发现在调用getInstance() 如果 clone 为 1, 则不直接进行 Statement.clone() 而是生成一个新的 Statement，这将导致设置的 RaiseErrorOnNotFound 被忽略，是否可以考虑在clone为1时，也带上 RaiseErrorOnNotFound 设置呢？如下：

		if db.clone == 1 {
			// clone with new statement
			tx.Statement = &Statement{
				DB:                   tx,
				ConnPool:             db.Statement.ConnPool,
				Context:              db.Statement.Context,
				Clauses:              map[string]clause.Clause{},
				Vars:                 make([]interface{}, 0, 8),
				SkipHooks:            db.Statement.SkipHooks,
				RaiseErrorOnNotFound: db.Statement.RaiseErrorOnNotFound,
			}
			if db.Config.PropagateUnscoped {
				tx.Statement.Unscoped = db.Statement.Unscoped
			}
		}
