Yes, that's true, but the ALTER statement by itself is not what's filling up the logical logs; it's all the individual INSERT statements that result from the ALTER, as the engine copies all the rows from the original table to the new table. These would not be logged if the database had logging turned off. June -- june_t@hotmail.com Lost in the wilds of Palo Alto, living on KitKat bars
