in reply to DBI Inserting undef as literal string 'null'

Here's three questions for you to consider...

  1. what does using whatever tool you are using to inspect your database return when you execute "select NULL"? (ie: is your tool giving you missleading info)
  2. what exactly does your table definition look like? ... do any of the columns have default values declared (ie: did someone declare the fields to have default values of the string "null" when they ment null)
  3. what do you get when you bind undef to an insert into a numeric column? (ie: if you still find that you have a string value of "null" in a numeric column, something is seriously screwed up in your database or your driver)
