Hi
You can use COALESCE.

Hi,
See if you can use 'Coalesce' like following (untested): -- Coalesce('1 : ' + convert(varchar(20),convert(decimal(8,2),NULLIF(sum(B),0)) / convert(decimal(8,2),NULLIF(sum(A),0))), cast(A as varchar) + ':' + cast(B as varchar)) -- Kamran [quoted text, click to view] "SqlBeginner" <SqlBeginner@discussions.microsoft.com> wrote in message news:95C61795-233A-4B91-8085-D00462333428@microsoft.com... > Hi, > > Can you tell me how to make use of Coalesce to get that result. > > Expected Output: > ---------------- > Column1 column2 A B C > aaa bbb 10 20 1:2 > aa1 bb1 20 40 1:2 > ... > ... > xyz abc 10 0 10:0 > > Regards > Pradeep > > "Kamran" wrote: > >> Hi >> >> You can use COALESCE. >> >> Regards, >> >> Kamran >> >> "SqlBeginner" <SqlBeginner@discussions.microsoft.com> wrote in message >> news:AAE84C2A-D4A1-432F-A8FC-33401B29B05E@microsoft.com... >> > Hi All, >> > >> > This is my existing query and i have given below the output sample as >> > well. >> > btw I am using SQL Server 2005. >> > >> > Select field1, field2, Sum(A) as A, Sum(B) As B, >> > '1 : ' + convert(varchar(20),convert(decimal(8,2),NULLIF(sum(B),0)) / >> > convert(decimal(8,2),NULLIF(sum(A),0))) as C >> > From >> > ( >> > Subquery comes here >> > ) As z >> > Group by field1, field2 >> > Order by field1, field2 >> > >> > Current Output: >> > ---------------- >> > Column1 column2 A B C >> > aaa bbb 10 20 1:2 >> > aa1 bb1 20 40 1:2 >> > ... >> > ... >> > xyz abc 10 0 NULL >> > >> > But where ever C is NULL i want to automatically display A:B i.e., >> > >> > Expected Output: >> > ---------------- >> > Column1 column2 A B C >> > aaa bbb 10 20 1:2 >> > aa1 bb1 20 40 1:2 >> > ... >> > ... >> > xyz abc 10 0 10:0 >> > >> > Can anyone help me in this? >> > >> > Regards >> > Pradeep >> >> >>
No it didn't work.

Yes Coalesce can be used here. Check the syntax and try out.
another quick solution is to make use of Case when statement. case when b=0 then cast(a as varchar(5)) + ':'+ cast(b as varchar(5) else begin ---- do whtver here---- end Regards Vadivel http://vadivel.blogspot.com [quoted text, click to view] "Kamran" wrote:
