These can be validations to control duplicate values or the validations about constraints applied on the table. There are multiple ways to do this. In this section, you will see an example where we will use this statement in an after insert trigger. We will insert a record in a table resulting in the firing of a trigger that will insert the same row in another table.

But the record will only be inserted if the same record does not exist already in the table. In this section, you will see an example in which we will update the same row using an after insert trigger.

Thus, you might have learned how you can update the same row using an after insert trigger in SQL Server. In SQL Server, you cannot create an after insert trigger on a view. Generally, a view is created from multiple base tables. When you try to insert a record into a view, changes have to be made to all the tables that are used for creating the view.

In this case, you get an error. Raiserror is used to throw a user-defined exception in SQL Server. We can use it with a trigger for validation. If the validation fails, we will throw an exception.

We will create an example where we will use the raiserror function to throw an error inside an insert trigger. Read SQL Server drop table if e x ists.

Sometimes, you need to roll back the insert transaction if a certain condition is not met. If the condition is met, the transaction will be committed, otherwise, the transaction will be rolled back. Thus, you might have learned how you can use the rollback statement after insert trigger in SQL Server. You might be thinking that what is a scope. A scope is just a module i. For example, if you have two insert statements in functions, both the statements are in the same scope.

This means it will not interfere with the triggers and reduce the complexity of the database schema. It is limited to a session. Therefore, if you are using an after insert trigger, you should use the IDENTITY function to get the last inserted identity value from the current session.

SeanGallardy, ahh yes you are correct. I had assumed that only 1 row was being updated. You know what they say about assumptions.

DaleBurrell you can add update statement with trigger if you want to update multiple rows. Best practice is to assume multiple rows and code accordingly.

This is not a good example for people unfamiliar with triggers as it teaches them bad habits. Reza Jenabi Reza Jenabi 3, 22 22 silver badges 29 29 bronze badges.

Good luck Modified0, t. Modified1 FROM dbo. Tyler Feldkamp Tyler Feldkamp 11 1 1 bronze badge. Added : FROM dbo. FutbolFan January Mmako January Mmako 1 1 silver badge 7 7 bronze badges.
