Hi i have a select query which goes like this...

SELECT ICN,SCCF_NUMBER,PLAN_RECEIPT_DATE,DATE_PAID,
INPUT_MEDIUM,FIN_CYCLE_DT,CHECK_NUMBER,
DISPOSITION_CODE,MONTH,
FROM DSNV.DWS_ITS_CLAIMS_H
WHERE PLAN_RECEIPT_DATE >= '2001-01-01' AND
HOME_HOST_IND = 'HOST'
ORDER BY ICN
WITH UR;

when i ran this i got some records.... the same query i with same fields i have retrieved thru focus program for the same table i got some records.......

when i saw the nubmber of records the records retrieved are same.

i wanted to check whther the fields are also same till ICN and SCCF_NUMBER i tried to compare the files in file aid .. i got differences.....

Differece was the order for SCCF_NUMBER where there are duplicate values the order is different for focus and the retrieval from IKJEFT01 Tool. when i checked for that particular ICN number in QMF the order was same as focus....

i am not able to decide what is wrong with the retrieval by using IKJEFT01 tool

can any one suggest me ....

SUM SCCF_NUMBER
FST.PLAN_RECEIVED_DT
LST.PAID_DATE
FST.FIN_CYCLE_DT
CHECK_NUMBER
DISPOSITION_CODE
MONTH

WHERE PLAN_RECEIPT_DT GE '2001-01-01'
WHERE HOME_HOST_IND EQ 'HOST'
BY ICN

its like this.....here fst lst concept i am not including in the select query .... i am doing in sort...... but with out adding first last in focus data and retrieving the data using the IKJEFT tool i am getting difference only for the duplicate data...

:-(

Hello,

Might a SUM and a SELECT return different results. . .?

Please try to pick a more meaningful Topic in the future. It helps when people are searching.

For comparing my data with focus and cobol i have removed sum and replaced print and also the fst and lst in focus.... i compared my data with focus retrieval and cobol retrieval in file aid for particular length i m getting differences....

I dont think my topic is not meaningful....

How about "IKJEFT01 and Focus yield different results"? Having the word Focus in the topic would have been more meaningful than "db2 query".

It was a problem with IFJEFT01 so i kept like that...i checked with order of retrieval from QMF and IKJEFT... when there are duplicates the order is changing....using IKJEFT

Hello,

Is the issue now that qmf and ikjeft01 give different results?

It is quite likely that the order of the retrieved rows is different because there are duplicates in the data and the system was not told how to order these duplicates. If you only ORDER BY ic, the sequence of the duplicates is unpredictable.

Has FOCUS gone away as part of the question?
