3. Can this issue be re-produced with the latest release?

4. What did you do?

struct po.SystemRole:

type SysRole struct {
	g.Meta `orm:"table:t_sys_role, do:true"`

	ID         interface{} `orm:"f_id,omitempty"           ` // 角色 ID
	Name       interface{} `orm:"f_name,omitempty"         ` // 角色名称
	NameCn     interface{} `orm:"f_name_cn,omitempty"      ` // 中文角色名称
	Type       interface{} `orm:"f_type,omitempty"         ` // 角色类型 Platform/Business
	Enabled    interface{} `orm:"f_enabled"                ` // 是否启用
	MenuNames  interface{} `orm:"f_menu_names,omitempty"   ` // 菜单名称列表
	Desc       interface{} `orm:"f_desc,omitempty"         ` // 角色描述
	UpdateTime interface{} `orm:"f_update_time,omitempty" `  // 更新时间
	CreateTime interface{} `orm:"f_create_time,omitempty" `  // 创建时间
}

select logic:

condition := &po.SysRole{Name: "SUPER_ADMIN", NameCn: ""}

	var record *entity.SysRole
	if err := s.Ctx(ctx).Where(condition).Scan(&record); err != nil {
		return nil, errs.NewOperateDBError(ctx, s.Table(), err)
	}

update logic:

        out  := &po.SysRole{Type: "Business"}
	if _, err := s.Ctx(ctx).Where(s.Columns().Name, name).Data(out).Update(); err != nil {
		return errs.NewOperateDBError(ctx, s.Table(), err)
	}

5. What did you expect to see?

• Expect the condition only has the filed "name" which i set when I select with the po.SystemRole struct.
• Expect to update the filed Type when I update with the po.SystemRole struct.

6. What did you see instead?

• Actually the condition has all the fields of po.SystemRole.
• Actually it update all the filed and set other fields to empty value.
