Find data after a failed trigger

[Evgeniy S]

Structure: There is a last_user_actions table and a user_actions table. The user_actions table has a trigger update_last_user_actions that updates the data after insert in the last_user_actions table.

Problem: The problem is that a new column was added to the last_user_actions table, but without a default value, as a result, new data was not entered either in user_actions or in last_user_actions because I forgot to set default value for new column.

Question: How can I find data that could not be successfully recorded?
