Creates a temporary table which is typically used for one-time calculations. Sandboxes can be populated with result data of any transformation, or pasted from the clipboard.
Data in sandboxes survives reloads – sandbox contents doesn't change on partial or full reloads. Although, it doesn't survive re-opening the project. When a project with a Sandbox transformation is opened all its sandboxes are empty.
Besides ad hoc calculations, sandboxes can be used in a few more cases:
Together with Either table
transformation Sandbox can be used to safely insert an arbitrary dataset into any point of a transformation chain, which can be useful for debugging and development purposes. In this scenario insert Either table
and point its second input to a table created using Sandbox transformation.
Sandboxes can be used to create an empty table as a starting point for further transformations. Some transformations (e.g. Run external program
might not need an input dataset, but they don't create a table. In this case a generic empty table can be created using Sandbox, and then Run external program
can be inserted after it.
Sandbox transformation has no parameters.
