Physical Query of OBIEE

Question

Hi All,
I noticed in many queried of OBIEE to database containing the select 0 as c1. Please let me know why it is firing 0 from table if so it always return zero for particular coulmn. Can any plz let me know whats the logic behind it..
Below is the one of the query where OBIEE uses select 0 as c1
select D1.c1 as c1,
D1.c2 as c2,
D1.c3 as c3,
D1.c4 as c4
from
(select D1.c1 as c1,
D1.c2 as c2,
D1.c3 as c3,
D1.c4 as c4
from
*(select 0 as c1,*
D1.c2 as c2,
D1.c1 as c3,
D1.c3 as c4,
ROW_NUMBER() OVER (PARTITION BY D1.c2, D1.c3 ORDER BY D1.c2 ASC, D1.c3 ASC) as c5
from
(select LAST_VALUE(D1.c4) OVER (PARTITION BY D1.c3 ORDER BY NVL2(D1.c4, 1, 0) , D1.c3 NULLS FIRST, D1.c5 NULLS FIRST ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) as c1,
D1.c2 as c2,
D1.c3 as c3
from
(select T156337.MCAL_PER_NAME_YEAR as c2,
T156337.MCAL_YEAR_WID as c3,
sum(T134466.BALANCE_GLOBAL1_AMT) as c4,
T156337.ROW_WID as c5
from
W_MCAL_DAY_D T156337 /* Dim_W_MCAL_DAY_D_Fiscal_Day */ ,
W_GL_GROUP_ACCOUNT_D T102174 /* Dim_W_GL_GROUP_ACCOUNT_D */ ,
W_GL_BALANCE_A T134466 /* Fact_Agg_W_GL_BALANCE_A */
where ( T102174.ROW_WID = T134466.GROUP_ACCT_WID and T102174.GROUP_ACCOUNT_NUM = 'AR' and T134466.BALANCE_DT_WID = T156337.ROW_WID )
group by T156337.ROW_WID, T156337.MCAL_YEAR_WID, T156337.MCAL_PER_NAME_YEAR
) D1
) D1
) D1
where ( D1.c5 = 1 )
) D1
order by c1, c2

Answer 1

I don't see it in NQQuery log:(
Ideally, it should be because it will hit BI Server. Moreover, I can see it (report's logical SQL) in BI Server Cache.
Any other thoughts?
