Log4net, ADONetAppender and Stored Procedure: Set Accuracy and Scaling?

The combination of what I am assuming is the small things that stop my application from database logging, as I expect.

  • The text team works. Both teams INSERTboth EXECwork, and the data is entered into the database
  • If I uncomment a parameter ExecutionTime, it stops working. , I know that someone was working at some point, but I can’t understand why uncommenting a parameter, let alone adding it, makes Appender fail silently.
    • An error was detected in debug. Listed and updated below with added accuracy and scale.
  • I'm trying to enable internal debugging and doesn't seem to want to work. Problem detected. Moved the configuration sections to the right place (not in log4net).
  • If I switch commandType to StoredProcedure, it stops working even if the text version is working
    • Another problem. Trying different things, but they were out of luck.

Update 1 Now that I have a Trace job, she complains that the DB team needs to explicitly set the accuracy and scale. You do not know how to do this, since none of the examples that I have seen has this set
