  John Paul Paul Jimmy Fred Mary 

I know ONLY the Name column in table1.
So in my application I read the whole Name column and encrypt each value.
Now I have to update the names of table1 with their encrypted values.
What can I do? (sorry for bad format of table..)

Answer 1

Assuming you have another table with columns like Name and EncryptedName , you can do the update with a join :

update table1 t1 join
       NamePairs np
       on t1.name = np.name
    set t1.name = np.EncryptedName;
