Mamta A. Satoor commented on DERBY-5121:
----------------------------------------
I am debugging the code to see what happens at the execution time of trigger
firing. Rick, you mentioned TemporaryRowHolderResultSet in one of your
comments. I will debug that further but do you know offhand if each trigger
gets it's own copy of TemporaryRowHolderResultSet. If so, then I can probably
maddle with how column mapping happens. This mapping can be different for
different triggers on the same table and I didn't want to mess up
TemporaryRowHolderResultSet if it is being shared by all the triggers on the
table which are going to get fired. Thanks
