I have this query

select 
a.Des as 'Alm', 
SUM (case k.IdE when 1 then 1 else 0 end) as Normal, 
SUM (case  k.IdE when 2 then 1 else 0 end) as Urgent  
FROM TblKBA a 
left join TblKBK k 
on a.idA = k.IdAr
group by a.Des

with this result

Alm	Normal	Urgent
U1.K1.WH1	6	5
U1.K1.WH2	9	9
U1.K2.WH3	0	0
U2.K3.WH4	0	0

i want to hide the alm row when normal or urgent are 0, in this example i want to hide the last two rows.

i want to get this result

Alm	Normal	Urgent
U1.K1.WH1	6	5
U1.K1.WH2	9	9

Easiest way to do this would be wrap what you have in a Common Table Expression (CTE) and then query the CTE.
To meet the normal or urgent are 0 requirement, the WHERE clause I used simply multiplied the columns because anything multiplied by 0 is 0.

SQL

; WITH cte (Alm, Normal, Urgent)
AS (
     SELECT     a.Des as 'Alm'
          ,     SUM (case k.IdE when 1 then 1 else 0 end) as Normal
          ,     SUM (case  k.IdE when 2 then 1 else 0 end) as Urgent
     FROM      TblKBA  a 
     LEFT JOIN TblKBK  k ON a.idA = k.IdAr
     GROUP BY  a.Des
)

SELECT *
FROM   cte
WHERE  ((Normal * Urgent) > 0)

If you want to filter out the rows where Normal and Urgent are both zero, then you can do that before you group them:

SQL

SELECT
    a.Des as 'Alm', 
    SUM(CASE k.IdE WHEN 1 THEN 1 ELSE 0 END) As Normal, 
    SUM(CASE k.IdE WHEN 2 THEN 1 ELSE 0 END) As Urgent  
FROM 
    TblKBA a 
    INNER JOIN TblKBK k 
    ON a.idA = k.IdAr
WHERE
    k.IdE In (1, 2)
GROUP BY
    a.Des
;

If you want to filter out rows where either Normal or Urgent is zero, then you can use the HAVING clause:

SQL

SELECT
    a.Des as 'Alm', 
    SUM(CASE k.IdE WHEN 1 THEN 1 ELSE 0 END) As Normal, 
    SUM(CASE k.IdE WHEN 2 THEN 1 ELSE 0 END) As Urgent  
FROM 
    TblKBA a 
    INNER JOIN TblKBK k 
    ON a.idA = k.IdAr
WHERE
    k.IdE In (1, 2)
GROUP BY
    a.Des
HAVING
    SUM(CASE k.IdE WHEN 1 THEN 1 ELSE 0 END) != 0
And
    SUM(CASE k.IdE WHEN 2 THEN 1 ELSE 0 END) != 0
;

Solution 2

select * from 
(select 
a.Des as 'Alm', 
SUM (case k.IdE when 1 then 1 else 0 end) as Normal, 
SUM (case  k.IdE when 2 then 1 else 0 end) as Urgent  
FROM TblKBA a 
left join TblKBK k 
on a.idA = k.IdAr
group by a.Des )A
where (A.Normal>0 and A.Urgent>0)
