The 'if exists' clause protects against an SQLite error raised if
you ask to delete a table that doesn't exist. The code will work
without it if the table exists, but will exit without creating the
table if not.
Thanks for a useful addition to the Org babel SQLite
documentation. I agree with you that Org mode tables are a
convenient way to enter SQL data, keeping in mind that table
columns can't be rearranged without changes to the SQL code.
All the best,
Tom

Cancel that, I was looking at a cached version of the page.
Thanks again for the documentation.
All the best,
