Imran,
what I do is the following:
create table temp_table as select primary_key_column, number_column from
table_to_be_changed;
update table_to_be_changed
set number_column=null;
alter table_to_be_changed modify(number_column(3,2));
declare
cursor c1 is
select primary_key_column, number_column
from temp_table;
begin
for c1_rec in c1 loop
update table_to_be_changed
set numebr_column = c1_rec.number_column
where primary_key_column = c1_rec.primary_key_column;
end loop;
commit;
end;
/
Hope this helps.

Perhaps:
Export, truncate table, alter table, import
or
Create <temp_table> as select * from <orig_table>,
truncate table <orig_table>,
alter table<orig_table>,
insert from <temp_table>,
drop <temp_table>

Hi,
i have a column set to number(3). However this needs
to be changed to number (3,2). But i cannot do a
straight alter table as there is data in the column.
how can i get round this?
cheers
