sum problem

Dear all
i have to count how many records in table A are in table B (for each year).

i have creted a resident table whith this script

table_a:

load TMP_KEY AS MATCH_KEY,
BARCODE_MATCH_OR AS MATCH_BARCODE_OR,
BARCODE_MATCH_AR AS MATCH_BARCODE_AR,
ANNO,
IF(BARCODE_MATCH_OR=BARCODE_MATCH_AR,NUM(1),NUM(0)) AS MATCH_CONTA
RESIDENT
MATCHATI_TMP;

TMP_KEY BARCODE_MATCH_AR BARCODE_MATCH_OR ANNO MATCH_CONTA
431525 431525 431525 2010 1
431867 431867 431867 2010 1
431915 431915 431915 2010 1
434535 434535 2010 0

the table_a contain 19663 records.

whith a pivot table i could sum the "match_conta" value .
I use the dimension ANNO but the result is wrong.

I don't understand why the sum(match_conta) return 106506

Someone can help me.

Many Thanks
Riccardo

Riccardo,

To match the 2 tables are you doing a join? If so, I would make sure that the join is not wrongly duplicating the rows.

Regards.

Hi Karl,

yes i have done a join for optimize

but ... If i display all fields for the target table with an ordinary table the system show me 19663 records, 11616 of these have the

fields "match_conta" = 1 .

So i suppose to have a value like 11616 for year ...

I'm not so expertize .. so i probably doing a mistake...

Many thank's Riccardo
