Query Editor UI guide
Query Editor is an interactive tool provided by 蜜豆视频 Experience Platform Query Service, which allows you to write, validate, and run queries for customer experience data within the Experience Platform user interface. Query Editor supports developing queries for analysis and data exploration, and allows you to run interactive queries for development purposes as well as non-interactive queries to populate datasets in Experience Platform.
For more information about the concepts and features of Query Service, see the Query Service overview. To learn more about how to navigate the Query Service user interface on Platform, see the Query Service UI overview.
Getting started getting-started
The Query Editor provides flexible execution of queries by connecting to Query Service, and queries only run while this connection is active.
Accessing Query Editor accessing-query-editor
In the Experience Platform UI, select Queries in the left navigation menu to open the Query Service workspace. Next, to start writing queries, select Create Query at the top right of the screen. This link is available from any of the pages in the Query Service workspace.
Connecting to Query Service connecting-to-query-service
The Query Editor takes a few seconds to initialize and connect to Query Service when it is opened. The console tells you when it is connected, as shown below. If you attempt to run a query before the editor has connected, it delays execution until the connection is complete.
How queries are run from Query Editor run-a-query
Queries executed from Query Editor run interactively which means that if you close the browser or navigate away, the query is cancelled. The same is true for queries made to generate datasets from query outputs.
Query authoring using the Enhanced Query Editor query-authoring
Using Query Editor, you can write, execute, and save queries for customer experience data. All queries executed, or saved in Query Editor are available to all users in your organization with access to Query Service.
Database selector database-selector
Select a database to query from the dropdown menu in the top right of the Query Editor. The selected database is shown in the dropdown.
Settings settings
A settings icon above the Query Editor input field includes an options to enable/disable dark theme or disable/enable auto-complete.
To enable dark or light themes, select the settings icon (
Auto-complete auto-complete
The Query Editor automatically suggests potential SQL keywords along with table or column details for the query as you write it. The auto-complete feature is enabled by default and can be disabled or enabled at any point from the Query Editor settings.
The auto-complete configuration setting is per user and remembered for the consecutive logins for that user. Disabling this feature stops several metadata commands from being processed and providing recommendations that typically benefit the speed of the author when editing queries.
Execute multiple sequential queries execute-multiple-sequential-queries
Use the Enhanced Query Editor to write more than one query and execute all queries in a sequential manner. The execution of multiple queries in a sequence each generate a log entry. However, only the results of the first query display in the Query Editor console. Check the query log if you need to troubleshoot or confirm the queries that were executed. See the query logs documentation for more information.
Execute selected query execute-selected-query
If you have written multiple queries but need to execute only one query, you can highlight your chosen query and select the
Run selected query icon. This icon is disabled by default until you select query syntax within the editor.
Cancel Query Editor session cancel-query
Take control of query execution and improve your productivity by canceling long-running queries. This action clears the Query Editor during a query run. Be aware, the query continues to execute in the background. If it is a CTAS query it will still generate an output dataset. To cancel the run in the editor and continue composing a SQL statement, select Cancel query after executing a query.
A confirmation dialog appears. Select Confirm to cancel the query run.
Result count result-count
The Query Editor has a maximum 50,000 row output. You can choose the number of rows are displayed at one time in the Query Editor console. To change the number of rows displayed in the console, select the Result count dropdown and select from the 50, 100, 150, 300, and 500 options.
Writing queries writing-queries
Query Editor is organized to make writing queries as easy as possible. The screenshot below shows how the editor appears in the UI, with the SQL entry field and Play highlighted.
To minimize your development time, you are recommended to develop your queries with limits on the number of rows returned. For example, SELECT fields FROM table WHERE conditions LIMIT number_of_rows. After you have verified that your query produces the expected output, remove the limits and run the query with CREATE TABLE tablename AS SELECT to generate a dataset with the output.
Writing tools in Query Editor writing-tools
Use the Query Editor鈥檚 writing tools to enhance your query authoring process. Features include options to format text, copy SQL, manage query details, and save or schedule your work as you progress.
Format text format-text
The Format text feature makes your query more readable by adding standardized syntax styling. Select Format text to standardize all the text within the Query Editor.
Copy SQL copy-sql
Select the copy icon to copy SQL form the Query Editor to your clipboard. This copy feature is available for both query templates and newly created queries in the Query Editor.
Query details query-details
To view a query in the Query Editor, select any saved template from the Templates tab. The query details panel provides more information and tools to manage the selected query. It also shows useful metadata such as the last time that the query was modified and who modified it, if applicable.
From the details panel you can generate an output dataset directly from the UI, delete or name the displayed query, view the query run schedule, and add the query to a schedule.
To generate an output dataset, select Run as CTAS. The Enter output dataset details dialog appears. Enter a name and description, then select Run as CTAS. The new dataset is displayed in the Datasets Browse tab. See the view datasets documentation to learn more about available datasets for your organization.
After you execute the Run as CTAS action, a confirmation message pops up to notify you of the successful action. This popup message contains a link that provides a convenient way to navigate to the query logs workspace. See the query logs documentation for more information on query logs.
Saving queries saving-queries
The Query Editor provides a save function that allows you to save a query and work on it later. To save a query, select Save in the top-right corner of Query Editor. Before a query can be saved, a name must be provided for the query using the Query Details panel.
When you save a query in the Query Editor, a confirmation message pops up to notify you of the successful action. This popup message contains a link that provides a convenient way to navigate to the queries scheduling workspace. See the schedule queries documentation to learn how to run queries on a custom cadence.
Scheduled queries scheduled-queries
Queries that have been saved as a template can be scheduled from the Query Editor. Scheduling queries allows you to automate query runs on a custom cadence. You can schedule queries based on frequency, date, and time, and also choose an output dataset for your results if necessary. Query schedules can also be disabled or deleted through the UI.
Schedules are set in the Query Editor. When using the Query Editor, you can only add a schedule to a query that has already been created, and saved. The same limitation does not apply to the Query Service API.
See the query schedules documentation to learn how to create query schedules in the UI. Alternatively, to learn how to add schedules using the API, read the scheduled queries endpoint guide.
Any scheduled queries are added to the list in the Scheduled queries tab. From that workspace you can monitor the status of all scheduled query jobs through the UI. On the Scheduled queries tab, you can find important information about your query runs and subscribe to alerts. The available information includes the status, schedule details, and error messages/codes if a run failed. See the Monitor scheduled queries document for more information.
How to find previous queries previous-queries
All queries executed from Query Editor are captured in the Log table. You can use the search functionality in the Log tab to find query executions. Saved queries are listed in the Templates tab.
If a query was scheduled, then the Scheduled Queries tab provides improved visibility through the UI for those query jobs. See the query monitoring documentation for more information.
[Limited Availability]{class="badge informative"} Object browser object-browser
Object browser is currently available only in a limited release. Contact your 蜜豆视频 representative to get early release access.
Use the object browser to easily search and filter datasets. The object browser reduces the time spent searching for tables and datasets in large environments with numerous datasets. With streamlined access to relevant data and metadata, you can focus more on query authoring and less on navigation.
To navigate your database with the object browser, enter a table name into the search field, or select Tables to expand the list of available datasets and tables. When using the search field, the list of available tables are dynamically filtered based on your input.
Every dataset contained in your selected database is listed in a navigation rail to the left of the Query Editor.
The schema displayed in the object browser is an observable schema. This means that you can use it to monitor changes and updates in real time as changes are immediately visible. The observable schemas help to ensure data synchronization and assists with debugging or analytics tasks.
Current limitations current-limitations
The following is a list of current limitations:
- Sequential query execution: Only one query can be executed at a time. While a query is in progress, no additional tables can be opened in the left navigation, as queries are processed sequentially.
- Extra rows in query logs: You may encounter extraneous queries labeled as 鈥淪HOW TABLES鈥 in the logs. These will be removed in future releases.
Access table metadata table-metadata
In addition to quick searches, you can now easily access metadata for any table by selecting the 鈥榠鈥 icon next to the table name. This provides you with detailed information about the selected table, that helps you to make informed decisions when writing queries.
Explore child tables
To explore child or linked tables, select the dropdown arrow next to a table name in the list. This expands the table to show any associated child tables, and gives a clear view of the data structure and allows for more complex query constructions. The icon next to the field name indicates the column鈥檚 data type, to help you identify it during complex queries.
Executing queries using Query Editor executing-queries
To run a query in Query Editor, you can enter SQL in the editor or load a previous query from the Log or Templates tab, and select Play. The status of query execution is displayed in the Console tab below, and output data is shown in the Results tab.
Console console
The console provides information on the status and operation of Query Service. The console displays the connection status to Query Service, query operations being executed, and any error messages that result from those queries.
Query results query-results
After a query has been completed, the results are displayed in the Results tab, next to the Console tab. This view shows the tabular output of your query, displaying between 50 and 500 rows of results depending on your chosen result count. This view allows you to verify that your query produces the expected output. To generate a dataset with your query, remove limits on rows returned, and run the query with CREATE TABLE tablename AS SELECT to generate a dataset with the output. See the generating datasets tutorial for instructions on how to generate a dataset from query results in Query Editor.
