Chris,
In the first crate table/select statement, you explicitely selected the columns you wanted from the order_log table (col1, col2, to_number(col3)).
In the insert/select statement, you are doing a select *. You now need
to
do a column by column comparison between the two tables. You will find
a
column mis-match - maybe a number column trying to be inserted into a
date
column?
Hope this helps.

Here's what i did:

create table order_log2 as select cola, colb, to_number(colc) colc,...
from
order_log;
=20
truncate table order_log
=20
alter table order_log modify (colc number);
=20
insert into order_log select * from order_log2;
=20
......and i get:
=20
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected NUMBER got DATE
=20

=20
it's not even on the column who's datatype i changed.
