DBA's,

Can anyone shed some light on the following query.

I have performed a single column update on 1 row (update basic set col1  =
99999998 where col1 = 999999999).  The following stats were displayed prior
to the update:

consistent gets 15291
db block changes 199
db block gets 1120

After the update the stats were as follows:

consistent gets 15350
db block changes 209
db block gets 1136

My question is what is it that causes the 'consistent gets' figure to
increase, I was under the impression that all blocks would be acquired in
current mode.

Many thanks for any replies.

Dave Leach
