# SHOW STREAM LOAD
|
|
## Description
|
|
This statement is used to show the execution of the specified import task
|
|
Grammar:
|
|
SHOW STREAM LOAD
|
|
[FROM both names]
|
|
[
|
|
WHERE
|
|
[LABEL [ = "your_label" | LIKE "label_matcher"]]
|
|
[STATUS = ["SUCCESS"|"FAIL"|]]
|
|
]
|
|
[ORDER BY ...]
|
|
[LIMIT limit][OFFSET offset];
|
|
|
|
Explain:
|
|
1) If db_name is not specified, use the current default DB
|
|
2) If you use LABEL LIKE, the label that matches the task contains the STREAM LOAD task of label_matcher
|
|
3) If LABEL = is used, the specified label is matched accurately.
|
|
4) If STATUS is specified, the STREAM LOAD status is matched
|
|
5) Arbitrary column combinations can be sorted using ORDER BY
|
|
6) If LIMIT is specified, the limit bar matching record is displayed. Otherwise, all of them will be displayed.
|
|
7) If OFFSET is specified, the query results are displayed from offset. By default, the offset is 0.
|
|
|
|
## example
|
|
1. Show all STREAM LOAD tasks of default DB
|
|
SHOW STREAM LOAD;
|
|
|
|
2. Show the STREAM LOAD task of the specified db. The label contains the string "2014_01_02", showing the oldest 10
|
|
SHOW STREAM LOAD FROM example_db WHERE LABEL LIKE "2014_01_02" LIMIT 10;
|
|
|
|
3. Show the STREAM LOAD task of the specified db, specify label as "load_example_db_20140102"
|
|
SHOW STREAM LOAD FROM example_db WHERE LABEL = "load_example_db_20140102";
|
|
|
|
4. Show the STREAM LOAD task of the specified db, specify status as "success", and sort it in descending order by StartTime
|
|
SHOW STREAM LOAD FROM example_db WHERE STATUS = "success" ORDER BY StartTime DESC;
|
|
|
|
5. Show the STREAM LOAD task of the specified dB and sort it in descending order by StartTime, and display 10 query results starting with offset 5
|
|
SHOW STREAM LOAD FROM example_db ORDER BY StartTime DESC limit 5,10;
|
|
SHOW STREAM LOAD FROM example_db ORDER BY StartTime DESC limit 10 offset 5;
|
