Query regarding Update the data using application

Question

I have scenario i need to update single record in the the application and insert into a table
for example
SELECT ContactID,FirstName,MiddleName,LastName,Description FROM Contact
Contact table contains 4 columns as explained. in the application there is one tab called Contact where it displays Above information
and description is non editable.
Now the new requirement has come user can update the description information and save information in a new column say 'Description1'
that means new column needs to be added in the db and also necessary changes needs to be done at the application side
For ex :SELECT ContactID,FirstName,MiddleName,LastName,Description,Description1 FROM Contact
Now when user views the contact table it should display description info by default from 'description' table.
If he edits he should see edited data from 'description1' table.
Can any body guide me please and send me sample update query please, and the logic should if updated data is there display that data from
 'description1' table other wise display from  'description' table

Hi Smash126,
You need to fire the update command once you have filled the description record. It should happen on the primary key column of the record.
For Example: 
UPDATE Contact
SET Description  = 'New Description',
Description1 = 'New Description'
where contactID = <<ContactID from application>>
This way both will updated to same value, and next time you will get the updated value.
Here is some ADO.Net links:
