GROUPING in HANA SQL

Hi Experts,

Here is what I am trying to do,

I have first 4 columns on the existing Table (HCC_PERNR, HCC_ZBEGDA, HCC_ZENDDA and HCC_OBJ)

I am trying to code for the last Column HCC_GROUP (group the values on change of HCC_OBJ)

Note : I can do that easily but there is one catch ; see HCC_OBJ -> 36000360 is coming twice , once from 2010 to 2011 and then from 2014 to 9999

after I get above I want to write following

SELECT HCC_PERNR, MIN(HCC_ZBEGDA) , MX(HCC_ZENDDA), HCC_OBJ, HCC_GROUP

FROM <ABOVE SELECT>

GROUP BY HCC_PERNR,HCC_OBJ, HCC_GROUP

The above statement should give me two rows for 36000360 (once during 2010/2011 & other one During 2014/9999)

If I just write the GROUP statement without the HCC GROUP , I would loose the split of 36000360 ; it would actually tell me 36000360 was from 2010 to 9999 ; which is wrong.

Thanks

Meps
