DataSpell 2022.3 Help

Query results

Usually, when you run a query, you receive results in a table format. Each statement appears in a separate tab in the Services tool window. For example, if you have two SELECT statements in the query, you will see two tabs in the tool window.

The Services tool window includes a list of consoles that are grouped according to a connection session to a data source.

For more information about query consoles and Services tool window, refer to Query consoles and Services tool window.

Result tabs

Open a new tab for each new query

By default, DataSpell updates the same tab with results each time you run a new query after the previous one. You can change this behavior and create a tab each time you run a new query.

  1. In the IDE settings Ctrl+Alt+S, go to Tools | Database | Query Execution.

  2. Select the Open results in new tab checkbox and click OK.

Use custom titles for tabs with results

You can define a tab title in the comment section before the query. In the Treat text as title after field, you can reserve a combination of symbols or characters after which any text will be treated as a tab title. By default, no combination is used, so any text after -- or /* is treated as a tab title.

  1. Open settings by pressing Ctrl+Alt+S, navigate to Tools | Database | Query Execution | Output and Results.

  2. In the Treat text as title after field, define a combination for tab titles.

    To disable this feature, open settings Ctrl+Alt+S, navigate to Tools | Database | Query Execution | Output and Results, and clear the Create title for results from comment before query checkbox.

    For more examples of custom titles for tabs, see Name the result tabs at youtube.com.

    Use custom titles for tabs with results

Pin the tab with query results

If one and the same tab is used to show your query results, and you get the result that you want to keep, you can pin the tab to the tool window.

  • Right-click the tab and select Pin Tab.

    Pin the result tab

In-Editor Results

You can also view the query results within the editor. To do that, use the In-Editor Results feature.

  • To toggle the In-Editor Results feature for the current file, click the In-Editor Results icon.

    Disable in-editor results for the current file
  • To toggle the In-Editor Results feature for all files across the IDE, open settings by pressing Ctrl+Alt+S and navigate to Database | Query Execution | Output and Results | Results. Clear the Show results in editor checkbox.

Result sets

View two result sets in the editor

  • Click the In-Editor Results button to view result sets one above another.

Edit values in the result set

  1. In the result set, click a cell value that you want to edit.

  2. Specify a new value and press Enter.

  3. To submit changes to a database, click the Submit icon (The Submit icon), or press Ctrl+Enter.

    Modify values in the result set

Compare two result sets

  1. Run queries to tables that you want to compare.

  2. In the Services tool window, click the Compare with icon (The Compare with icon), and select the result set that you want to add to diff.

  3. If needed, change a value of the Tolerance parameter in the comparison dialog. The Tolerance parameter defines a maximum number of differences that are allowed between two result sets. For example, if you want to consider two rows as equal if their data differs in a single column, enter 1 in the Tolerance field.

    See another example of comparing two result sets in Compare data at youtube.com.

    Compare result sets

Output tab

View query log

On the Output tab in the Services tool window, you can see a log of user and internal queries.

  1. Open a console for a data source F4.

  2. Run a query for a data source.

  3. In the Services tool window, select a corresponding session for your console and click the Output tab.

    View query log

Enable output from the DBMS_OUTPUT package (Oracle)

In Oracle, the DBMS_OUTPUT package enables you to send messages from stored procedures, packages, and triggers. You can enable or disable showing the contents of the DBMS_OUTPUT buffer in the output pane.

  • To toggle the DBMS_OUTPUT option, click the Enable SYS.DBMS_OUTPUT button the Enable SYS.DBMS_OUTPUT button on the toolbar of the Services tool window.

If all the rows are currently shown, navigation icons and the corresponding commands are inactive. You can see the limit between the navigation buttons. You can change it here by clicking and selecting the necessary limit or in settings.
