Hi,
I think that I have a conceptual problem and I hope anyone could help me.
If I write a trigger AFTER INSERT and I have one error in this trigger, the
record (that I think was already inserted) is not inserted.
Example:
INSERT INTO tableX <record1>
trigger sumRecords AFTER INSERT under tableX to accumulate the records
inserted by hour
if there is an error in the commands executed for this record, <record1> is
not in the tableX
If this occurs in a trigger BEFORE INSERT, I can understand, but, if it is
AFTER INSERT, I believe that the record is already inserted.
What is wrong on it?
Thanks in advance
Josi Perez

Sure, because the whole transaction is rolled back on error.

Thank you for your answer.
Without considering the errors, the transaction should not start after the
AFTER INSERT?

Anything happening in a trigger is always part of the same database
transaction as the database action which fired the trigger.
