Is there a way to see constraint validation errors while loading xml into a
DataSet ? I'm interested in the line number in the xml file which is causing
the error. I've enclosed the relevant stack trace below.

Hi there,
Is it possible to add a unique constraint on two columns in a table, so that
the constraint is a composite of the two? i.e. these two columns together
should be unique...?
i.e.
column1 column2
1 1
1 2

I'm trying to build a table that will store a history of records
by enumerating the records. I want the newest record to always
be number ZERO, so I created a trigger on my table to handle the
assignment of version numbers:
CREATE TRIGGER "trg_audio_file_insert" BEFORE INSERT
ON "public"."audio_file" FOR EACH ROW
EXECUTE PROCEDURE "public"."trg_audio_file_insert"();
My trigger function looks like this...

My question, stated as simply as possible, is: must a constraint
violation, as defined by the standard, cause compilation to halt?
I believe that in the presence of a constraint violation, at
least one diagnostic is required, which, at the discretion of the
compiler writer, may be either an "error" or a "warning."
Generally however, an error halts compilation and a warning does
not. This would seem to imply that it is up to the compiler...

Dear all,
I would like to open another topic to try to clarify a doubt raised on
my previous post today with the subject 'printf("%d%d%d")'.
Reading through the standard, I cannot find a clear definition of what
is a constraint violation.

Violation of UNIQUE KEY constraint 'IX_surveyQuestions'. Cannot insert duplicate key in object 'dbo.surveyQuestions'.
This might seem like a simple matter of trying to insert a row with ID=20 when there's already one with that ID, but the problem is a bit more complicated. The table is supposed to auto-increment the value for the primary key when a new record is inserted. But no matter what I do, I can't seem to insert more than one record...
