ISSUE: 1585
|
|
TITLE: Problem altering numeric field type
|
|
DESCRIPTION:
|
|
create table tab (a numeric(4,2));
|
|
insert into tab values (99.99);
|
|
select * from tab;
|
|
|
|
A
|
|
=======
|
|
99.99
|
|
|
|
alter table tab alter a type numeric(4,3);
|
|
select * from tab;
|
|
|
|
Statement failed, SQLCODE = -802
|
|
arithmetic exception, numeric overflow, or string truncation
|
|
|
|
BTW the database is not "corrupted" too badly - you can revert the change back by
|
|
alter table tab alter a type numeric(4,2);
|
|
and the engine is clever enough to convert data from stored format to requested one
|
|
directly, not through all intermediate format versions.
