Creating an In-Memory Data Source

To create an in-memory data source you need to use the CreateMemoryDataStore function. When this function runs it will create an in-memory data source with no columns or data, which will persist until the end of the current session.

While an in-memory data source is active you can use in-memory functions to configure it, add data, create columns, and more.

Implementation:

  1. Open the Expression Editor where you want to add the expression.
  2. Enter the following:

CreateMemoryDataStore( DataSourceName );

  1. Replace DataSourceName with a unique keyword to name the data source. This will be used to reference it in other expressions.
  2. Save the expression.
  3. As the new data source will initially be empty, you will need to add columns to the new data source by using the AddColumnToDataSource function.
