You can write a value to the database with a DatabaseRawWrite, using an array input to trigger the write (array of one element, an integer or small string), with the SQL "insert into tablename (value) values (?);". And you could use a DatabaseRawLookup and use the SQL statement “ Select value from tablename limit 10” to get value.
