If you use Microsoft Power Flow for automatisation within your company, you might have the need of starting a workflow or task in case an SQL-Server table got updated. To use this trigger, you need to add a column to your table which has the type: rowversion.
For further information, pls. take a look at the documentation from Microsoft: https://docs.microsoft.com/en-us/sql/t-sql/data-types/rowversion-transact-sql?view=sql-server-ver15
The rowversion has nothing todo with a timestamp – so if you need to have e.g. the last modified date on your record, you need an additional column in your table schema.
