RE: can I prevent rounding of a/b when a and b are integers

Actually, in Oracle, at least the last time I was working on it, if you divided an int column by an int column, you got an int result which, if I remember correctly, was truncated. For people who write SQL, this is a fairly well known issue that we confront, and solve using the solution

I checked both oracle and impala and in both 1/3 is 0.333 and not 0. I think that SQL writer is not a programmer and he does not care about data type. He just want to get the correct results. BTW – it is not only constant, even expression like sum(case when then 1 else 0 end) / count(*) will

I think it is fairly standard in programming languages for / to mean integer division when the operands used are integers. Therefore 1/3=0 is not a surprising result to me; other programming languages I have worked in give 1/3=0. However if one of the operands to / is a decimal, the result is

Thanks for the workaround , but it is not a solution for our case. We have an app that let user write their own SQL and we can’t tell them to always write int numbers as xxx.0 I created https://issues.apache.org/jira/browse/PHOENIX-3312 Regards, Noam From: James Taylor

Adding some more workaround , if you are working on column:- select cast(col_int1 as decimal)/col_int2; select col_int1*1.0/3; On Wed, Sep 21, 2016 at 8:33 PM, James Taylor wrote: > Hi Noam, > Please file a JIRA. As a workaround, you can do SELECT 1.0/3. > Thanks, >

Hi Noam, Please file a JIRA. As a workaround, you can do SELECT 1.0/3. Thanks, James On Wed, Sep 21, 2016 at 12:48 AM, Bulvik, Noam wrote: > Hi, > > > > When I do something like select 1/3 from the result will be > integer value (0) and not double or alike(0.33….). Is

Hi, When I do something like select 1/3 from the result will be integer value (0) and not double or alike(0.33). Is there some configuration that can force the result to be double BTW - when executing the same query in oracle (select 1/3 from dual ) I get correct result same in impala
