Re: logging the input values the procedure/function is called with

Can you explain what problem(s) you've encountered doing this?

To me it sounds as if all you would need is to declare log_input_values as an autonomous transaction (Only if storing data even when transaction rolls back), then having an insert statement run if the debug level is set.

Of course the call to log_input_values will need to contain the values you call with and I believe it will also need to send the name of the proc. I don't know of a way in pl*sql to get the calling procedures name. I guess it may be possible to get it by getting the call stack and parsing it.

What version of Oracle do you use?

If you go thought this trouble, wouldn't it make more sense to have a call at the end so you can store start and end time, alternatively update with the end time if you need data also for failed transactions.
