```
EXPORT TABLE xxx
...
PROPERTIES
(
"label" = "mylabel",
...
);
```
And than user can use label to get the info by SHOW EXPORT stmt:
```
show export from db where label="mylabel";
```
For compatibility, if not specified, a random label will be used. And for history jobs, the label will be "export_job_id";
Not like LOAD stmt, here we specify label in `properties` because this will not cause grammatical conflicts,
and there is no need to modify the meta version of the metadata.

SHOW EXPORT
description
该语句用于展示指定的导出任务的执行情况
语法：
SHOW EXPORT
[FROM db_name]
[
WHERE
[ID = your_job_id]
[STATE = ["PENDING"|"EXPORTING"|"FINISHED"|"CANCELLED"]]
[LABEL = your_label]
]
[ORDER BY ...]
[LIMIT limit];
说明：
1) 如果不指定 db_name，使用当前默认db
2) 如果指定了 STATE，则匹配 EXPORT 状态
3) 可以使用 ORDER BY 对任意列组合进行排序
4) 如果指定了 LIMIT，则显示 limit 条匹配记录。否则全部显示
example
1. 展示默认 db 的所有导出任务
SHOW EXPORT;
2. 展示指定 db 的导出任务，按 StartTime 降序排序
SHOW EXPORT FROM example_db ORDER BY StartTime DESC;
3. 展示指定 db 的导出任务，state 为 "exporting", 并按 StartTime 降序排序
SHOW EXPORT FROM example_db WHERE STATE = "exporting" ORDER BY StartTime DESC;
4. 展示指定db，指定job_id的导出任务
SHOW EXPORT FROM example_db WHERE ID = job_id;
5. 展示指定db，指定label的导出任务
SHOW EXPORT FROM example_db WHERE LABEL = "mylabel";
