从补丁 198 开始，Amazon Redshift 将不再支持创建新的 Python UDF。现有的 Python UDF 将继续正常运行至 2026 年 6 月 30 日。有关更多信息，请参阅[博客文章](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/)。

# SYS\$1LOAD\$1DETAIL
<a name="SYS_LOAD_DETAIL"></a>

返回用于跟踪或排查数据加载的信息。

此视图记录了在每个数据文件加载到数据库表中时的进度。

此视图对所有用户可见。超级用户可以查看所有行；普通用户只能查看其自己的数据。有关更多信息，请参阅 [系统表和视图中的数据可见性](cm_chap_system-tables.md#c_visibility-of-data)。

## 表列
<a name="SYS_LOAD_DETAIL-table-columns"></a>

[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/zh_cn/redshift/latest/dg/SYS_LOAD_DETAIL.html)

## 示例查询
<a name="SYS_LOAD_DETAIL-sample-queries"></a>

以下示例返回上次 COPY 操作的详细信息。

```
select query_id, trim(file_name) as file, record_time
from sys_load_detail
where query_id = pg_last_copy_id();

 query_id |               file               |          record_time        
----------+----------------------------------+----------------------------
 28554    | s3://dw-tickit/category_pipe.txt | 2013-11-01 17:14:52.648486 
(1 row)
```

以下查询包含 TICKIT 数据库中初次加载表时的条目：

```
select query_id, trim(file_name), record_time
from sys_load_detail
where file_name like '%tickit%' order by query_id;

 query_id |           btrim          |          record_time

向此系统视图的日志文件写入一个记录的事实并不表示加载操作已作为其所属的事务的一部分成功提交。要验证加载提交，请查询 STL\$1UTILITYTEXT 视图并查找与 COPY 事务对应的 COMMIT 记录。例如，此查询基于针对 STL\$1UTILITYTEXT 的子查询联接 SYS\$1LOAD\$1DETAIL 和 STL\$1QUERY：

```
select l.query_id,rtrim(l.file_name),q.transaction_id
from sys_load_detail l, sys_query_text q
where l.query_id=q.query_id
and exists
(select xid from stl_utilitytext where xid=q.transaction_id and rtrim("text")='COMMIT');

 query_id |           rtrim           |  transaction_id
