There are all kinds of new features in the new version of SQL Server 2019. One of the ones I am excited about is the additional information you now receive be default when you try to insert data that is too long to fit into an existing field. In prior versions you would get the message below, but you would have no idea what row or field was causing the issue:
Msg 8152, Level 16, State 14, Line 5 String or binary data would be truncated.
