What must be true for a column to be part of snapshot change tracking?

For a column to be part of snapshot change tracking, it is essential that at least one column in the table must track changes. This aspect is fundamental to the mechanism of change tracking, as it allows the system to capture what has changed in the data over time. Without designated columns that can capture changes, the entire purpose of snapshot tracking fails, as there would be no basis to identify and log modifications.

This requirement emphasizes the system's ability to monitor alterations, which can then be reflected in data reporting and analysis processes. The idea is to have a reliable method to capture changes, so the user has access to a historical context regarding the data's evolution. In summary, ensuring that at least one column is configured for change tracking is crucial for the correct functioning of snapshot change tracking, allowing for effective data management and insight generation over time.
