Work with virtual test data in a database sandbox

Virtual test data are data that are not persistent in a database. These data are stored only in memory and are used to:

• Validate a data model by manipulating and querying the data in a database sandbox.
• Generate test data.

Populate the database sandbox

You can fill in the database sandbox with virtual test data manually, or you can populate it automatically using the data generators (see the section “Assign Data Generator settings”).
To populate the virtual test data grid automatically:

1. Open the “Database sandbox” form by clicking on “Tools | Database sandbox”. On the “Data” tab select the column that you want to fill in with virtual data. You need to set the number of rows that you want to populate in the grid.
2. Then, click the populate button .

3. You can delete all populated data by clicking the delete button . You can also add, edit, or delete a single row.

To populate the virtual test data grid manually, use the toolbar buttons to manually fill in the grid. You can also edit or delete an existing row.

Note: If you fill in data manually, be careful when the data type is serial or auto-increment; you need to respect the sequencing rule. If you insert random data, an issue can arise when you generate persistent data from the virtual data to populate your database.

View virtual test data

You can display the data as a grid or as a form. To switch the view, click the Grid View button or the Form View button at the bottom.
