- Oracle and SQL Server support a maximum of 38 digits of which up to 38 may be decimals. You may use fields with a larger definition, but if these fields are on a file, the column will be created with a smaller size. For example, Packed(63,9) will be created as (38,9). If the field has more than 38 significant digits and you try to write it to the database, an error will occur.
