Firstly thank you for all the detailed responses. I have bitten the bullet and rewritten the script in a much neater, strict complying form. I was still getting the initial error message of fetch without an execute, however it looks as if the problem was down to the single quotes wrapping the database name in the query so thank you space_monk for suggesting I remove them - the script is now running flawlessly!
