Somar valores e mostrar em coluna...

Olá,

Eu queria somar o RECID com o TESTE1 e apresentar em uma outra coluna.

Como eu faço isso?

SELECT

INKREQUESTSVIEW.RECID AS RECID,
CONVERT(datetime, SWITCHOFFSET(CONVERT(datetimeoffset, INKREQUESTSVIEW.TRANSDATETIME), DATENAME(TzOffset, SYSDATETIMEOFFSET()))) AS TRANSDATETIME,
convert(int, datediff(ss,'01-01-1970 00:00:00',TRANSDATETIME)) AS TESTE1
from INKREQUESTSVIEW where TRANSDATETIME > '2016-08-01 00:00:00.000' AND ITEMID = '002.0001.164'
order by TESTE1

Resultado

RECID TRANSDATETIME TESTE1 5637144590 2016-08-01 04:19:46.000 1470035986 5637144590 2016-08-01 04:21:27.000 1470036087 5637144590 2016-08-01 21:39:25.000 1470098365 5637144590 2016-08-01 21:40:11.000 1470098411 5637144590 2016-08-02 04:26:39.000 1470122799 5637144590 2016-08-02 18:02:29.000 1470171749 5637144590 2016-08-02 21:55:35.000 1470185735 5637144590 2016-08-03 13:56:40.000 1470243400 5637144590 2016-08-04 10:37:51.000 1470317871 5637144590 2016-08-05 18:03:59.000 1470431039 Obrigado...
