CF 5 generating slow DB queries

[AdamK]

We are using CF 5 against Oracle DB (9.2.0.5) when running snapshots of the
Database we see lots of queries generated by cfserver.exe which are obviously
generated internally by CF and are taking lots of CPU time. how are these
generated? is this the internal implementation of CFUPDATE/CFINSERT ? how can
we make CF stop doing this? here's an example ------------------------- select
to_char(null), ac.owner, ac.table_name, acc.column_name, acc.position,
ac.constraint_name from all_constraints ac, all_co ns_columns acc where
ac.owner=acc.owner and ac.constraint_type= 'P' and
ac.constraint_name=acc.constraint_name and ac.table_nam e like 'CUSTOMER'
escape '\'
