| Create SQL log

Select this checkbox to create a report of the SQL command(s) that were used to update the database.

- Queries will only be logged when using selections that update data already present in the database table.
- For instance, when choosing the Drop and recreate or Truncate and insert options, the queries will not be logged, since the existing table was completely overwritten.
