// 添加数据库引用恢复逻辑
Status ExternalTable::read_fields(DataInput* in) {
// 先调用父类方法
Table::read_fields(in);
// 读取数据库ID
int64_t db_id;
in->read_int64(&db_id);
// 核心修复：根据ID找到Database并设置引用
if (db_id != -1) {
_db = Catalog::instance()->get_db(db_id);
if (_db == nullptr) {
LOG(WARNING) << "Cannot find db " << db_id << " for table " <<
_name;
}
}
// 继续读取其他数据...
return Status::OK();
