Pivoting a single field in a table
I have a table of the following structure:
Name Type Line UniqueID Key Value
I need to select all the fields except UniqueID field and add a key 'UniqueID' and a Value field with the value of the UniqueID to the result set.
For example if I have three records:
Name Type Line UniqueID Key Value
John Doe Employee 2 test333 SSN 123-45-2345
John Doe Employee 3 test333 Address 555 Rodeo Drive
Jane Doe Visitor 2 test444 SSN 345-67-8907
my result set would need to be:
Name Type Line Key Value
John Doe Employee 2 UniqueID test333
John Doe Employee 2 SSN 123-45-2345
John Doe Emplyee 3 Address 555 Rodeo Drive
Jane Doe Visitor 2 UniqueID test444
Jane Doe Visitor 2 SSN 345-67-8907
Do I use pivots? Can anyone point me into the right direction?
This is kind of an odd request, at least to me. But anyhow, you can approach it a few ways. One way is to use cross apply:

Based on your comments, we'll chuck the union all method.
Here is an incredibly ugly and kludgy unpivot, combined with a union (to get the unique ids):
from table1) t1
newvalue for newkey in ([Value])
(newkey2 for newvalue2 in ([key])) u2
