When dbForge Studio for Oracle executes any statement returning a result set, the retrieved data is displayed in the Data Editor of the data view of the same SQL document or Object Viewer. This topic shows how to edit the data in grid; for information about customizing data grid, as well as sorting, grouping and filtering, visit Viewing Data in Grid topic.
Tip: To discard changes, click the Cancel Edit button or select the Cancel Edit option on the shortcut menu.
In dbForge Studio for Oracle, you can also edit data right after retrieving it from a table or in the data view after any query was executed.
To retrieve data, select Retrieve Data on the shortcut menu of the table in the Database Explorer. To make received data editable, you can also choose the table name from the Table drop-down list on the toolbar
or leave it read-only by selecting (read-only).
If you choose the read-only mode, you will gain in the performance aspect, as the application will work faster in this mode.
To edit data in join query results, you should set the table you want to edit data from to the editable mode, as described above. After you set one table as editable, the data of other tables included into the result will become light-gray.
When you change the mode of any table from read-only to editable or vice versa, a balloon with the corresponding message is shown on the status bar.
To view values of CHAR and VARCHAR fields you should take into account the following points:
If length >= 200 is stated in the column type, buttons will be shown in the grid. Click these buttons, and the editor will be shown in a separate window.
If there are more than 4000 symbols in a cell, data can not be edited directly in the cell. To edit data in such cells, you should click the […] button.
Use the shortcut menu or the corresponding buttons under the grid. For example, you can do the following:
To insert NULL (instead of empty string), select Set Value To, and then click Null on the shortcut menu. You can also use the CTRL+0 key combination.
Tip: Use Set Value To menu to quickly set an empty string, zero, or a current date.
You can easily select and copy the data just like cells in a spreadsheet. Do either of these actions:
Tip: Using the CTRL key, you may include and exclude cells to selection. Any number of rows may be copied and pasted to some other application, for example, a spreadsheet, but when you paste data in data grid, only the first row will be pasted.
Actual document look may slightly vary from the above image depending on the product you use.
dbForge Studio for Oracle allows you to control data editing with transactions. When working with grid-based editor, you can access the following buttons on the Connection toolbar: Begin Transaction, Commit, and Rollback.
Some queries return read only data, for example, queries with aggregate functions (count, avg etc.), or data, retrieved from non-updatable views. Such data can’t be edited. It is also impossible to edit the result of executing of the script with several select statements.
When working with grid, you can see special indicators near to the focused cell. These indicators reflect current editing state.
The row is focused.
The row is being edited.
The row has been edited.
Incorrect value was entered into a cell. You must either fix the value or press the ESCAPE key to cancel changes made to the cell.
