之前的分页接口都是正常的，突然就报错了Error parsing column 0 (Id=<null>)

}分页查询代码如下，执行到这里报错的 var list = await reader.ReadAsync<T>();

if (pageIndex <= 0 || pageSize <= 0)

}
var skip = (pageIndex - 1) * pageSize;

queryParams.Add("skip", skip, DbType.Int32);
queryParams.Add("take", pageSize, DbType.Int32);
var connection = await GetDbConnectionAsync();
var dbTransaction = await GetDbTransactionAsync();
using var reader = await connection.QueryMultipleAsync(sb.ToString(), queryParams, transaction: dbTransaction);
//using var reader = await connection.QueryMultipleAsync(sb.ToString(), queryParams);
var total = await reader.ReadFirstAsync<long>();
var list = await reader.ReadAsync<T>();//这里报错了
return new PagedResultQto<T>(total, list.ToList());
}查看返回的报错信息是id字段那报错了，网上说是代码里定义的模型跟数据库表里的类型不一致导致的，我看了下不是这个原因，最后查看查询出来的数据如下：id是1和2两列，那就不对了，代码里定义的是guid类型的，查询出来应该是36位的字符串才能正常转换成guid，所以报错了
综上，是数据库中的异常数据导致的
