Write queries and explore data in the SQL Editor

The Azure Databricks UI includes a SQL editor that you can use to author queries, browse available data, and create visualizations. You can also share your saved queries with other team members in the workspace.

SQL editor UI

After opening the editor, you can author a SQL query or browse the available data. The text editor supports autocomplete, autoformatting, and various other keyboard shortcuts.

You can open multiple queries using the query tabs at the top of the text editor. Each query tab has controls for running the query, marking the query as a favorite, and connecting to a SQL warehouse. You can also Save, Schedule, or Share queries.

Connect to compute

You must have at least CAN USE permissions on a running SQL Warehouse to run queries. You can use the drop-down near the top of the editor to see available options. To filter the list, enter text in the text box.

SQL Warehouse selector

The first time you create a query, the list of available SQL warehouses appears alphabetically. The last used SQL warehouse is selected the next time you create a query.

The icon next to the SQL warehouse indicates the status:

  • Running Running
  • Starting Starting
  • Stopped Stopped

Note

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

The selected SQL Warehouse will restart automatically when you run your query. See Start a SQL warehouse to learn other ways to start a SQL warehouse.

Browse data objects in SQL editor

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

The schema browser showing the samples catalog, nyctaxi database, trips table, and the columns in that table.

You can navigate Unity Catalog-governed database objects in Catalog Explorer without active compute. To explore data in the hive_metastore and other catalogs not governed by Unity Catalog, you must attach to compute with appropriate privileges. See Data governance with Unity Catalog.

Note

If no data objects exist in the schema browser or Catalog Explorer, contact your workspace administrator.

Click Refresh Schema Icon near the top of the schema browser to refresh the schema. You can filter the schema by typing filter strings in the search box.

Click a table name to show the columns for that table.

Create a query

You can enter text to create a query in the SQL editor. You can insert elements from the schema browser to reference catalogs and tables.

  • Type your query in the SQL editor.

    The SQL editor supports autocomplete. As you type, autocomplete suggests 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_name as t where t., autocomplete recognizes that t is an alias for table_name and suggests the columns inside table_name.

    Autocomplete alias

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

Turn autocomplete on and off

Live autocomplete can complete schema tokens, query syntax identifiers (like SELECT and JOIN), and the titles of query snippets. It’s enabled by default unless your database schema exceeds five thousand tokens (tables or columns).

Use the toggle beneath the SQL Editor to turn live autocomplete off or on.

  • To turn off live autocomplete, press Ctrl + Space or click the Auto Complete Enabled button beneath the SQL editor.

Save queries

The Save button near the top-right of the SQL editor saves your query.

Important

When you modify a query but don’t explicitly click Save, that state is retained as a query draft. Query drafts are retained for 30 days. After 30 days, query drafts are automatically deleted. To retain your changes, you must explicitly save them.

Edit multiple queries

By default, the SQL editor uses tabs so you can edit multiple queries simultaneously. 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.

Queries Dialog

Run a single query or multiple queries

To run a query or all queries:

  1. Select a SQL warehouse.

  2. Highlight a query in the SQL editor (if multiple queries are in the query pane).

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

    Query result

Note

Limit 1000 is selected by default for all queries to limit the query return to 1000 rows. If a query is saved with the Limit 1000 setting, this setting applies to all query runs (including in dashboards). 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 stop an executing query that another user started by viewing the Terminate an executing query.

Query options

You can use the Vertical Ellipsis kebab context menu near the top of the query editor to access menu options to clone, revert, format, and edit query information.

Download results: You can download results as a CSV, TSV, or Excel file.

You can download up to approximately 1GB of results data from Databricks SQL in CSV and TSV format and up to 100,000 rows to an Excel file.

The final file download size might be slightly more or less than 1GB, as the 1GB limit is applied to an earlier step than the final file download.

Note

If you cannot download a query, your workspace administrator has disabled download for your workspace.

Past executions

You can view previous runs for the query, including the complete query syntax. Past executions open in read-only mode and include buttons to Clone to new query or Resume editing. This tab does not show scheduled runs.

The record shows each time the query has run, including the specific query syntax.

Explore results

Returned query results appear below the query. The Raw results tab populates with the returned rows. You can use built-in filters to reorder the results by ascending or descending values. You can also use the filter to search for result rows that include a specific value.

Filter results with search

You can use tabs in the result pane to add visualizations, filters, and parameters.

Scatter plot visualization of data with options to create a new visualization, filter, or parameters.

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.

Automate updates

You can use the Schedule button to set an automatic cadence for query runs. Automatic updates can help keep your dashboards and reports up-to-date with the most current data. Schedueled queries can also enable Databricks SQL alerts, a special type of scheduled task that sends notifications when a value reaches a specified threshold.

See Schedule a query.

See What are Databricks SQL alerts?.

Share queries

The Share button lets you share your query with other users in your workspace. When sharing, choose the between the following options:

  • Run as owner (owner’s credentials): This setting means that viewers are able to see the same query results as the query owner. This applies to scheduled or manual query runs.
  • Run as view (viewers credentials): This setting limits results to the viewer’s assigned permissions.

See Configure query permissions.
