Reviewing and Editing Data¶
To review or modify data, right click on a table or view name in the Browser tree control. When the context menu opens, use the View/Edit Data menu to specify the number of rows you would like to display in the editor panel.
To modify the content of a table, each row in the table must be uniquely identifiable. If the table definition does not include an OID or a primary key, the displayed data is read only. Note that views cannot be edited; updatable views (using rules) are not supported.
The editor features a toolbar that allows quick access to frequently used options, and a work environment divided into two panels:
- The upper panel displays the SQL command that was used to select the content displayed in the lower panel.
- The lower panel (the Data Grid) displays the data selected from the table or view.

The toolbar includes context-sensitive icons that provide shortcuts to frequently performed tasks.

The Data Grid
The top row of the data grid displays the name of each column, the data type, and if applicable, the number of characters allowed. A column that is part of the primary key will additionally be marked with [PK].
To modify the displayed data:
- To change a numeric value within the grid, double-click the value to select the field. Modify the content in the square in which it is displayed.
- To change a non-numeric value within the grid, double-click the content to access the edit bubble. After modifying the contentof the edit bubble, click the Save button to display your changes in the data grid, or Cancel to exit the edit bubble without saving.
To enter a newline character, click Ctrl-Enter or Shift-Enter. Newline formatting is only displayed when the field content is accessed via an edit bubble.
To add a new row to the table, enter data into the last (unnumbered) row of the table. As soon as you store the data, the row is assigned a row number, and a fresh empty line is added to the data grid.
To write a SQL NULL to the table, simply leave the field empty. When you store the new row, the will server fill in the default value for that column. If you store a change to an existing row, the value NULL will explicitly be written.
To write an empty string to the table, enter the special string ‘’ (two single quotes) in the field. If you want to write a string containing solely two single quotes to the table, you need to escape these quotes, by typing ‘’
To delete a row, press the Delete toolbar button. A popup will open, asking you to confirm the deletion.
To commit the changes to the server, select the Save toolbar button. Modifications to a row are written to the server automatically when you select a different row.
