Need help on t-sql 2012

I have the following data in a temp table:    

declare @TEMP4 table (PID int, Comp1 varchar(10), Comp2 varchar(10), Comp3 varchar(10), Comp4 varchar(10), Comp5 varchar(10));

insert into @TEMP4 values(12345, NULL, NULL, '123', NULL, NULL);
insert into @TEMP4 values(23456, '234', NULL, 'ewr', NULL, NULL);
insert into @TEMP4 values(34567, NULL, 'acc', NULL, NULL, 'def');
insert into @TEMP4 values(45678, NULL, NULL, 'jkl', NULL, NULL);
insert into @TEMP4 values(56789, NULL, NULL, NULL, NULL, 'we1');
insert into @TEMP4 values(23450, 'abc', 'acc', 'exy', 'ert', 'def');

would like to have result as follow:

PID            comp1 comp2 comp3 comp4 comp5
12345      123         NULL   NULL  NULL  NULL
23456      234        ewr      NULL  NULL  NULL
34567       def        NULL   NULL  NULL   NULL
45678      jkl          NULL   NULL   NULL   NULL
56789     we1       NULL   NULL   NULL   NULL
23450     abc        acc      exy       ert       def

Thank you for helping!!

This expert suggested creating a Gigs project.
I think COALESCE can help you out.

For comp1: COALESCE(Comp1, Comp2, Comp3, Comp4, Comp5)
For comp2: COALESCE(Comp2, Comp3, Comp4, Comp5)
For comp3: COALESCE(Comp3, Comp4, Comp5)

and so on...

BTW: what happened with 'acc' in the third record?

ouch, activated "gig suggestion" by accident lol, please ignore that part :)

Unpivot the data, reorder it and create a new pivot:

        PID INT ,
        Comp1 VARCHAR(10) ,
        Comp2 VARCHAR(10) ,
        Comp3 VARCHAR(10) ,
        Comp4 VARCHAR(10) ,
        Comp5 VARCHAR(10)

VALUES ( 12345, NULL, NULL, '123', NULL, NULL ) ,
       ( 23456, '234', NULL, 'ewr', NULL, NULL ) ,
       ( 34567, NULL, 'acc', NULL, NULL, 'def' ) ,
       ( 45678, NULL, NULL, 'jkl', NULL, NULL ) ,
       ( 56789, NULL, NULL, NULL, NULL, 'we1' ) ,
       ( 23450, 'abc', 'acc', 'exy', 'ert', 'def' );

WITH Unpivoted
     FROM   @TEMP4 T UNPIVOT(CompValue FOR CompType IN(Comp1, Comp2, Comp3, Comp4, Comp5)) U ) ,
            U.CompValue ,
                                              ORDER BY U.CompType ASC ) AS VARCHAR(255)) AS NewCompType
     FROM   Unpivoted U )
FROM   Reordered R
    PIVOT (   MIN(CompValue)
              FOR NewCompType IN ( Comp1, Comp2, Comp3, Comp4, Comp5 )) P;

Hi ValentinoV - thank you very much for you help.

your suggestion come up close:

select      PID,
            Comp1 = COALESCE(Comp1, Comp2, Comp3, Comp4, Comp5),
            comp2 = COALESCE(Comp2, Comp3, Comp4, Comp5),
            comp3 = COALESCE(Comp3, Comp4, Comp5),
            comp4 = COALESCE(Comp4, Comp5),
              comp5 = Comp5
from @TEMP4

PID       Comp1  Comp2  Comp3  Comp4  Comp5
12345  123       123   123  NULL  NULL
23456  234       ewr   ewr  NULL  NULL
34567  acc        acc   def     def    def
45678  jkl         jkl     jkl   NULL  NULL
56789  we1   we1  we1  we1  we1
23450  abc   acc  exy  ert  def
