How to convert Column header to Row for loannumber [closed]

Answer 1

You should be able to use the following with the UNPIVOT function:

select loanNumber,
  amount, 
  amounttype
from #temp
unpivot
(
  amount
  for amounttype in (AmntType1, AmntType2, AmntType3)
) unp;

See SQL Fiddle with Demo.

Or because you are using SQL Server 2008 R2, this can also be written using CROSS APPLY:

select loannumber, 
  amount,
  amounttype
from #temp
cross apply
(
  values
    ('AmntType1', AmntType1),
    ('AmntType2', AmntType2),
    ('AmntType3', AmntType3)
) c (amounttype, amount);
