Data Editor and Viewer

The settings on this page define how table data are shown and modified in your database consoles and data editors.




Limit page size to

Number of table rows that are shown on one page. If you do not want to limit the number of rows displayed simultaneously, clear the checkbox.

Also, you can change the page size by clicking the Change page size list of the pagination toolbar.

Consider the following example where Limit page size to is set to 2:

Limit page size to

Result set prefetch size

Number of rows from a database that is retrieved in one chunk.

A bigger number means less round trips between IDE and a database but more memory for storing a chunk.

Filter history size

Number of recently-used filtering conditions that are saved for a table in a data editor. Consider the following example where Filter history size is set to 2. The filter history box contains only two conditions.

To open the filter history in the editor, click the Filter Criteria field and press Alt+ArrowDown.

Maximum size of a binary large object to be loaded in bytes.

Data Presentation



Use custom font

Set the dedicated font for your data. The font is applied for query results and data editor, not for query consoles and your SQL files.


Automatically transpose tables

Configure when you want to transpose tables and views when you open them in the data editor. In a transposed view, columns and rows are interchanged. Note that this setting does not transpose query results.

  • Never: do not transpose a table.

  • If a table has one record: transpose only tables with a single record.

  • Always: always transpose tables.

Show boolean values as

Set how you want to display boolean values in the data editor. You can select between the following options.

  • Text: boolean values are shown as text. Click a boolean cell to select a value from the drop-down list.

    display boolean values as text
  • Checkboxes: boolean values are shown as checkboxes. If the checkbox is selected, the value is true. If the checkbox is cleared, the value is false. To set NULL or DEFAULT values, right-click a cell and select Set NULL or Set DEFAULT.

Data Sorting



Sort tables by numeric primary key

Configure how to sort table records by the numeric primary key. Two options is available: Ascending or Descending.

Add columns to sorting

Select what action to use when you want to add columns to stacked sorting. The default is Alt and a click.

When you click the column name, the column data is sorted. The column sorting is not stacked by default. It means that if you click a column name to sort data by, the sorting based on other columns will be cleared. If you prefer to use the stacked sorting, click a column name while pressing Alt.
