Are you sure your all of your ont values Will fot into decimal(3,2)? You Will get overflow If the int are higher than 9. Decimal(3,2) handles values from 0.00 to 9.99

Don't forget negative -0.01 to -9.99

1 answer: sort voted first

If all of your integers are small enough to fit into that size of numeric column, then just use alter column, here is an example:

create table intTable (col1 int)

insert into intTable values (1)

insert into intTable values (2)


alter table intTable alter column col1 numeric(3, 2)

However, if you try it with values that are too large, it will give you an arithmetic overflow error. In that case, you either need to increase the size of the numeric type you are converting it to or remove the large values first.
