hi everybody, I've got a problem
SELECT
substring(A.tanque1,charindex(':',A.tanque1)+1,charindex(')',A.tanque1)-charindex(':',A.tanque1)-1) AS CAPACTIDAD1,
substring(A.tanque2,charindex(':',A.tanque2)+1,charindex(')',A.tanque2)-charindex(':',A.tanque2)-1) AS CAPACTIDAD2,
(cast(CAPACIDAD1 as FLOAT) + cast(CAPACIDAD2 as FLOAT)) AS TOTAL123
from table

may be this

SELECT CAPACTIDAD1,CAPACTIDAD2,
(COALESCE(cast(CAPACIDAD1 as FLOAT),0) + COALESCE(cast(CAPACIDAD2 as FLOAT),0)) AS TOTAL123
FROM
(
SELECT
substring(A.tanque1,charindex(':',A.tanque1)+1,charindex(')',A.tanque1)-charindex(':',A.tanque1)-1) AS CAPACTIDAD1,
substring(A.tanque2,charindex(':',A.tanque2)+1,charindex(')',A.tanque2)-charindex(':',A.tanque2)-1) AS CAPACTIDAD2
from table
)t
