View data

You can browse and edit data in three modes: Table, Tree, Text, and Transpose. To switch between these modes, click the View as button () and select the mode that you need.

• Transpose: viewing mode in which rows and columns are interchanged. You can combine this checkbox with other viewing modes.

  To make this mode a default for tables and views, open settings by pressing CtrlAlt0S and navigate to Tools | Database | Data Editor and Viewer. From the Automatically transpose tables list, select Always. When this option is enabled, query results are not transposed.

  

• Table: the default viewing mode of table data. Data in a table is stored in a cell that is an intersection of a vertical column and horizontal row.

  

• Tree: viewing mode in which data is displayed in the key-value table with the possibility to expand the key cell if it contains children nodes. Data from the expanded children node is distributed between key and value columns. You might consider using this mode to work with JSON and array data.

  

• Text: viewing mode in which data is displayed as a text.

  

Value editor is a separate editor where you can edit data that is stored in the cell. To open Value editor, in the cell context menu select Open in Value Editor.

If you store one-line JSON in a cell, you can click the Toggle Formatting icon. This action formats one-line XML and JSON strings.

You can preview images in the value editor. To do that, right-click the cell that contains an image and select View Image in the context menu.

Note that to leverage the performance issues, the default LOB size is limited to 1024 bytes. It means that only 1024 bytes are loaded to the table editor. To increase this size and view larger images, open settings by pressing CtrlAlt0S, navigate to Tools | | Data Editor and Viewer, and change the value of the Maximum number of bytes loaded per value option.

In the Aggregate view, you can select values of multiple cells and get a single summary value. To open Aggregate view, in the cell context menu select Show Aggregate View.

Click the gear icon () on the toolbar of the Aggregates tab to view, enable, and disable aggregates. To access the bundled scripts, select Go to Scripts Directory. Bundled scripts are located in Scratches and Consoles | Extensions | Database Tools and SQL | data | aggregators. The directory will open in the Project tool window .

Also, you can create your own aggregate scripts. To add your own aggregator, place your script to the aggregators directory.

tip

Aggregate scripts and extractors are interchangeable. If you have previously used an extractor that gets just one value, you can copy it to the aggregates directory and use it for aggregates.

You can use charts to visualize the database objects data and plot your query result sets in data editor. The available chart types are as follows: bar, pie, area, line, scatter, bubble, stock, area range, and histogram. You can also group your data.

Depending on what you are working with, the plot is displayed in split mode or instead of the table:

• Database objects data and DSV files: split mode.

• In-editor results and query results set in Services tool window: instead of the table.

Plot a chart

• To visualize your data, click Show Chart on the data editor toolbar.

  Default chart type is selected automatically depending on the data types. To view the exact value, hover over it on the chart.

Configure a chart

You can view your data in either one of the supported chat types. Use the axes settings to plot the data you need with the available columns.

1. On the chart toolbar, click Show Series Settings.

2. In the chart type selector, click the icon of the type that you want to plot.

3. For each axis, configure its settings:

   • Click Add Column and select the column that you want to plot.

   • Click Modifier to modify the data display.

Plot multiple series

1. On the chart toolbar, click Show Series Settings.

2. To plot one more series with the data from the same table, click Add new series and configure the new series.

3. To delete a series, click Remove in the upper-right corner of the series settings pane.

warning

The Geo data viewer works only if JCEF is enabled. In rare cases, when you enable JCEF, GoLand might crash. It can happen if you have installed plugins that use JavaFX. If the crash happened, refer to Recover GoLand after enabling JCEF.

note

To work with geographical data, you must install the Postgis extension on your PostgreSQL server. For more information about the installation process, refer to the Postgis documentation.

The Geo viewer is a graphic viewer that you can use to explore geospatial data in your database. The Geo viewer opens in the Services tool window. You can click rows to navigate to the corresponding area on the map or click a pin on the map to navigate to the corresponding row.

To detach the Geo viewer tab from the Services tool window, drag it from the Services tool window.

Currently, GoLand supports coordinates in the following formats: WKT, WKB, and PostGIS geometry 4326.
