Hi, I want to mark that the following records inserted or updated belong to a certain transaction. Unless i know the explicit begin/end, i cannot use just sticking a blob in a column, because it will change for every call to blob. what i want is during begin transaction store this value in a key/value table as 'tranid'/<blob> and delete it at end of transaction. this can be queried either by application or trigger. but i expect this insertion to happen in a trigger like the original proposal.

If changing applications then you can also change them to create that blob value. If using a trigger then you can insert into that trigger creation of the blob value if it doesn't exist. Is there something wrong with such solutions?
