Admin Settings - Queries

The Queries page lists information about the last 50 queries that Looker submitted to your database. If you’d like to see information about queries older than that, try the Usage section of Looker.

Basic Query Information

Column	Definition
Time	The start time of the query, displayed in your application time zone.
Status	The status of the query, which can include: Cache: Looker returned the results from its cache, instead of running a duplicate query against the database. Complete: The query completed successfully. Error: The query wasn’t able to complete successfully because an error occurred, the details of which can be found by clicking the Details button. Cancelled: The query was cancelled by Looker or the user. Waiting for PDT: The query needs to wait for a persistent derived table to be built before it can be executed. Building PDT: A persistent derived table is in the process of being built. Queued: The query is waiting to be executed because too many queries are already in progress (queries can be limited by Looker in your connection setup or your database). Running: The query is in the process of being run. Unknown: Looker wasn’t able to determine what happened with this query.
Connection	The Looker connection under which this query was run.
User	The user who ran this query, if that can be determined. Some queries are not executed by a specific user, such as when Looker creates a persistent derived table, or when an unknown user accesses a public Look.
Source	The source of the query in Looker, such as the Explore page or the SQL Runner. If possible, a link to saved Look, or the query ID along with the name of the model and Explore, is also displayed. Some queries will not have additional information, such as those run in the SQL Runner.
Runtime	The time it took to run the query. This includes the construction of the query, any time the query spent in the queue, transit to and from the database, and database execution of the query. If the query is currently running, the runtime will show how long the query has been running. For queries that were run previously, the runtime will also show an estimate of how much time the query will take to finish running. The estimate is based on the duration of the last run of the query, and will say something like “of about 2s”.
Details Button	See below for additional explanation.

The Details Button

Clicking the Details button to the right of any query will bring up additional information about that query. The Query Details pop-up includes the following:

An Info section that includes details about the query (see the table below).
A SQL section that shows the raw SQL that was executed against the database. Context Comments will not appear in the Query Details information. To prevent comments from affecting query caching, Looker adds the context comments to outgoing SQL commands right before the SQL is sent to the database.
An Open in SQL Runner link that will open the query in SQL Runner.

The Info section includes the following information:

Section	Definition
History ID	The history ID of the query, if available.
Status	The status of the query, as described above.
Connection	The Looker connection under which this query was run.
User	The user who ran this query, if that can be determined. Some queries are not executed by a specific user, such as when Looker creates a persistent derived table, or when an unknown user accesses a public Look.
Source	The source of the query in Looker, such as the Explore page or SQL Runner. If possible, additional information is displayed, such as a link to the saved Look, the query ID, model name, Explore name, fields selected, and so on.
Start Time	The start time of the query, displayed in your application time zone.
End Time	The finish time of the query, displayed in your application time zone.
Runtime	The length of time it took to run the query.

Query Killing

Looker will automatically stop a query that is still running when you close the browser tab in which the query is running. You can also stop a query that is running from the Queries page. Any query that is still running shows a Stop button to the right of the query. Click Stop to kill the query.

Looker’s ability to kill a query depends on the database dialect’s ability to support this functionality. The list below shows which dialects support query killing in the most recent Looker release:
