解説

When this property is set to true, the 本製品 creates a new column named RowNumber and uses it as the key for update and delete operations. When set to false, no row number column is created, and a custom schema must define a key column for modification operations.

This property is useful for performing update or delete operations on CSV files that do not include a natural primary key.
