Answer 1

FOR UPDATE
AS
    declare @empid int;
    declare @empname varchar(100);
    declare @empsal decimal(10,2);
    declare @audit_action varchar(100);
    declare @old_v varchar(100)

    select @empid=i.Col_Name1 from inserted i;  
    select @empname=i.Col_Name2  from inserted i;   
    select @empsal=i.Col_Name2 from inserted i;
    select @old_v=d.Col_Name from deleted d

    if update(Col_Name1)
        set @audit_action='Updated Record -- After Update Trigger.';
    if update(Col_Name2)
        set @audit_action='Updated Record -- After Update Trigger.';

    insert into Employee_Test_Audit1(Col_name1,Col_name2,Col_name3,Col_name4,Col_name5,Col_name6(Old_values)) 
    values(@empid,@empname,@empsal,@audit_action,getdate(),@old_v);

    PRINT '----AFTER UPDATE Trigger fired-----.'
