Query tasks

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 in SQL editor 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 SQL editor appears, loaded with the following query in the query pane:

   -- 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 (1000). After a few seconds, the query results are shown below the query in the results pane.

   

4. Click Save.

5. In the Save query dialog box, click Save (change the query name to a name of your choice).

View and organize queries

Queries can be viewed in one of two ways:

• New queries can now be viewed in the workspace browser by clicking Workspace in the sidebar. These queries are viewable, by default, in the Home folder. Users can organize queries into folders in the workspace browser along with other Databricks objects. To view and organize currently existing queries, users (or admins) must migrate them into the workspace browser. For information on the Databricks SQL workspace browser, including migration, see Databricks SQL Workspace browser.

• All queries, regardless of creation time or migration status, can also be viewed by clicking the Queries in the sidebar. By default, objects in the Queries windows are sorted in reverse chronological order. You can reorder the list by clicking the column headings.

Organize queries into folders in the workspace browser

You can now organize new and existing queries into folders in the workspace browser along with other Databricks objects. For more information, see Databricks SQL Workspace browser.

Filter the list of saved queries in the queries window

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

Create a query in SQL editor

1. Choose one of the following methods to create a new query using the SQL editor:

   • Click SQL Editor in the sidebar.

   • Click New in the sidebar and select Query.

   • In the sidebar, click Queries and then click + Create Query.

   • In the sidebar, click Workspace and then click + Create Query.

   The SQL editor displays.

2. In the data warehouses drop-down list, select a SQL warehouse. To filter the list, enter text in the text box.

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

   The icon next to the SQL warehouse indicates the status:

   • Running

   • Starting

   • Stopped

   Note

   If there are no SQL warehouses in the list, contact your Databricks SQL administrator.

Create a query using Terraform

• You can also create a query with the Databricks Terraform provider and databricks_sql_query.

• You can create a visualization for a query with databricks_sql_visualization.

• You can create a sample dashboard with queries by using dbsql-nyc-taxi-trip-analysis.

Browse data objects in SQL editor

If you have metadata read permission, the schema browser in SQL editor displays the available databases and tables. You can also browse data objects in Data Explorer.

Note

If there are no data objects in the schema browser or in Data Explorer, contact your Databricks SQL administrator.

• You must select a running SQL warehouse.

• To see a data object, you must either be the data object owner or be granted privileges to the object.

• To refresh the schema, click .

  

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

• To show the columns in a table, click the table.

  

Construct a query

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

• To insert an object from the schema browser into the SQL editor, click the double arrow on the right of a data object.

• Type your query in the SQL editor.

  The SQL 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.

  

• (Optional) When you are done editing, click Save.

Edit multiple queries

By default, the SQL editor uses tabs so you can edit multiple queries at the same time. To open a new tab, click +, then select Create new query or Open existing query. Click Open existing query to see your list of saved queries. click My Queries or Favorites to filter the list of queries. In the row containing the query you want to view, click Open.

Note

If you right click on a tab, you’ll see options to Close others, Close left, Close right, and Close all. If you right click on the first or last tab, the options to Close left or Close right are not available.

Execute a single query or multiple queries

To run a query or all queries:

1. Select a SQL warehouse.

2. Highlight a specific query in the SQL editor (if there are multiple querie in the query pane).

3. Press Ctrl/Cmd + Enter or click Run (1000) to display the results as a table in the results pane.

   

Note

• If a warehouse is stopped and you attempt to run a query, the warehouse is started. To manually start a warehouse, follow the steps in Start a warehouse.

• Limit 1000 is selected by default for all queries to ensure that the query returns at most 1000 rows. If you want to return all rows for this query, you can unselect LIMIT 1000 by clicking the Run (1000) drop-down. If you want to specify a different limit on the number of rows, you can add a LIMIT clause in your query with a value of your choice.

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 and view query info

To set a query description:

1. Click the kebab context menu next to the query and click Edit query info.

   

2. In the Description text box, enter a description and then click Save.

To view query info:

To view when a query was created or updated, click the next to the query and click Edit query info.

Revert to a saved query
