Is there a way to perform data validation using CHECK constraints in t-sql and to show somehow the data which did not pass the check constraint?

Is there a way to perform data validation using CHECK constraints in t-sql and to show somehow the data which did not pass the check constraint?
Yes, that is what CHECK constraints are for: Implementing data validation that can’t be done through table modelling
No, the only information you will get back from CHECK constraints is an error message when provided data has failed to meet the CHECK constraint requirements. It’s up to you to review the data.
A trigger would be the next likely option, to have the ability to redirect the attempted data to a table for logging.
