Query tasks

Preview

This feature is in Public Preview.

Run your first query

When you log in to Databricks SQL for the first time, an onboarding panel appears to help you get started quickly. If you are not an administrator, running your first query is the first onboarding task.

Note

If you have dismissed the onboarding panel, you can run this query by following the steps in Create a query later in this article.

1. If you don’t see the onboarding panel, look for Tasks Completed in the sidebar, and click it.

   

2. In the onboarding panel, click Run your first query. The query editor appears, loaded with the following query:

   -- We've given you a sample query below to help get started.
   -- Just hit "Run" to run the query and get your results.
   SELECT
     concat(pickup_zip, '-', dropoff_zip) as route,
     AVG(fare_amount) as average_fare
   FROM
     `samples`.`nyctaxi`.`trips`
   GROUP BY
     1
   ORDER BY
     2 DESC
   LIMIT 1000
   

   This query runs against the nyctaxi database in the SAMPLES catalog, which is readable in all workspaces.

3. Click Run. After a few seconds, the query results are shown below the query.

   

View the list of saved queries

Click Queries in the sidebar. The Queries list displays.

By default, queries are sorted in reverse chronological order by the Created By column. You can reorder the list by clicking the column headings.

Filter the list of saved queries

You can filter the list of queries by the list of queries you have created (My Queries), by favorites, and by tags.

Create a query

1. Do one of the following:

   • Click Create in the sidebar and select Query.
   • Click Queries in the sidebar and click the + New Query button.

   The query editor displays.

2. If not selected, select the data sources tab:

   

3. Click the icon and select a SQL endpoint. To filter the list, enter text in the text box.

   

   The first time you create a query the list of available SQL endpoints displays in alphabetical order. The next time you create a query, the last used SQL endpoint is selected.

   The icon next to the SQL endpoint indicates the status:

   • Running
   • Starting
   • Stopped

   Note

   If there are no SQL endpoints, contact your Databricks SQL administrator.

Browse data objects

If you have metadata read permission, the schema browser displays the available databases and tables.

Note

If there are no data objects, contact your Databricks SQL administrator.

You can also browse data objects in the data explorer.

1. In the box below a SQL endpoint, click the icon and select a database.

   

   Note

   • You must select a running SQL endpoint.
   • In order to see a data object in the schema browser, you must either be the data object owner or be granted privileges to the object.

   To refresh the schema, click the button.

   

   You can filter the schema by typing filter strings in the search box:

   

2. Click a table to shows its columns.

   

Construct a query

You construct a query by inserting elements from the schema browser or typing in the query editor.

• In the schema browser, click the double arrow on the far right of a data object.

  

• Type in the query editor.

  The query editor supports autocomplete. As you type, autocomplete suggests valid completions. For example, if a valid completion at the cursor location is a column, autocomplete suggests a column name. If you type select * from table as t where t., autocomplete recognizes that t is an alias for table and suggests the columns inside table.

  

When you are done editing, click Save.

Edit multiple queries

When the tabbed editor is enabled, you can edit multiple queries at the same time.

• Click the . A tab with the query name New Query displays.

  

• Click the Open Query link. The queries dialog displays.

  

  1. Optionally click My Queries or Favorites to filter the list of queries.

  2. In the row containing the query you want to view, click the Open button. The query displays in a new tab.

     

Execute a query

To execute a query:

1. Select a SQL endpoint.

2. Specify a query in the query editor.

3. Press Ctrl/Cmd + Enter or click the Execute button.

   

Note

• If an endpoint is stopped and you execute a query, the endpoint is started. To manually start an endpoint, follow the steps in Start an endpoint.
• The Limit 1000 checkbox is selected by default to ensure that the query returns at most 1000 rows. If you know that there are more rows, you can unselect the checkbox and specify a LIMIT clause in your query.

The query result displays in the Table tab.

Terminate a query

To terminate a query while it is executing, click Cancel. An administrator can terminate an executing query that was started by another user by viewing the Terminate an executing query.

Set query description

To set a query description:

1. Click the query info tab.

   

2. Click the Add description link or the existing description.

   

3. Edit the description and press Enter.

If your query has a schedule it will refresh automatically. To manually refresh a query in between automatic refreshes, click the Refresh button.

Save a query

To save a query, press Ctrl/Cmd + S or click the Save button. Only saved queries display in the Queries list.

Revert to a saved query

When you edit a query, a Revert link displays next to the Save button.

You can click Revert to go back to your saved version. Your changes are persisted to browser storage when you leave, but the browser may still display warnings about losing work.
