what is the difference between delete and truncate?
Answer Posted / nithya
The basic difference between delete and truncate is 'high
water mark'. High water mark indicates the max level to
which the data has risen in the table.
Deleting a table removes only the data from it whereas
Truncating a table removes all the data from the table and
resets the relevant pointers including 'high water mark'.
