Extending Decimal Range Throws 8k Limit Error

Hi,

I need to extend my decimal field range from decimal(8,4) to decimal(19,4), however, while doing so, it throws the following error

Command

alter table dbo.temp
    alter column field_1 decimal(19,4) NULL

Error Message

Msg 1792, Level 16, State 1, Line 1
Alter table 'temp' failed because the added fixed column might cause existing data to go beyond the maximum allowable table row size of 8060 bytes.

Please note the following:

1. This is in SQL Server 2012 - If I try this in SQL Server 2008 R2, it works fine.

2. If I delete all the data in the table, it still wont let me extend the range.

Let me know if you need any more info.

Thanks..
