This table can store amounts in va

Answer 1

Martlark's answer for Oracle led me to this solution for SQL Server:

select
  left(cast(Amount as varchar), len(cast(Amount as varchar)) - DecimalPlaces) +
  left('.', DecimalPlaces) +
  right(cast(OriginalCurrencyAmount as varchar), DecimalPlaces
) as FormattedAmount
from MyTable
