Hi,
I'm looking for a way to create a custom, for our application parsable,
error message on constraint violation.
The perfect thing would be, having table names, schemas and primary keys
in that error message.
My first thought was to create a function which gets triggered by the
constraint violation, which creates the custom error. But I have not
found any information if this is possible to create a trigger on a
constraint violation, and if yes, how could that be done?
I would be glad, If someone could light me up on that issue.
Thanks in advance and Kind Regards,
Michael
