table file car
sum sales by country

when there is no sales data for a particular country, that country will not print.

I recall there is a way to make it print; ie, country with 0 sales. I just can't remember what it is. Can someone tell me what it is? Thanks in advance.

Yes, but only if your model is hierachical...

Viewing things from focus isn't it always hierarchical?

Let me rephrase that...

...it only works if you have parent-child segment in you master/businessview.

Please correct me if I'm wrong, I'd like to use things like SET ALL = ON and WHERE INCLUDES/EXLCUDES.

it is a db2 database table; so, I am not sure if it is considered hierarchical. But, I have tried set all = on. It did not work (makes no difference). I think set all = on applies in situation where you have a join. When there is no join involved, that does not do a thing?

Is the db2 source a single table or a view?

You can check your db2 adapter parameter settings with this command:

SQL DB2 ?

You may get more information about how your FOCUS query is being processed by db2 by placing this command before your FOCUS query:

SQL DB2 SET EXPLAIN ON

Two programming methods to manufacture rows for which there are none.

1) Use the "Specifying Your Own Sort Order" technique:

-SET &ECHO=ALL;

TABLE FILE CAR
SUM
COUNTRY BY COUNTRY NOPRINT

ON TABLE SET HOLDLIST PRINTONLY
ON TABLE HOLD AS HCOUNTRY
END
-RUN

-SET &NBR_COUNTRY = &LINES;

-* ONE LESS READFILE IN THE REPEAT STATEMENT
-SET &NBR_COUNTRY = &NBR_COUNTRY - 1;

TABLE FILE CAR
SUM
SALES
BY COUNTRY ROWS

-READFILE HCOUNTRY

'&COUNTRY'

-REPEAT ENDHCOUNTRY &NBR_COUNTRY TIMES
-READFILE HCOUNTRY
OVER '&COUNTRY'

-ENDHCOUNTRY
END
-RUN

2) Use the MORE command:

-SET &ECHO=ALL;

TABLE FILE CAR
SUM
COMPUTE SALES/I6 = 0;
BY COUNTRY

ON TABLE HOLD AS HCOUNTRY
END
-RUN

TABLE FILE CAR
SUM
SALES
BY COUNTRY

MORE
FILE HCOUNTRY
END
-RUN

If I understand you correctly..
1. 'car' is DB2 table.
2. car.SALES can contain NULL.
3. You would like to treat car.SALES as
being zero (0), when it is NULL.

I'd be tempted to create a DEFINE field and set it to SALES when SALES is not NULL (missing) and to zero (0) when SALES is NULL (missing).

Then replace SALES with your DEFINE field, within your TABLE command.

thank you, Francis. I believe #2 will work. I am not sure how #1 will work because the first hold file HCOUNTRY will certainly not contain the zero sales country. What good is it to loop through the country values in the HCOUNTRY file?

Besides, it looks awfully performance poor if it is a big file with lots of countries to loop through.

You could try PRINTing the records to a HOLD file. PRINT might extract all of the records (including those with missing values) and you could then apply your SUM to the HOLD file. But since WebFOCUS will do the summing instead of DB2, performance could be affected if it's a large result set.

Another idea is to add a field to your original SUM query that always has a value. For example:

TABLE FILE CAR
 SUM
  CAR NOPRINT
  SALES
 BY COUNTRY
END

or even....

TABLE FILE CAR
 SUM
  COUNTRY
  SALES
 BY COUNTRY NOPRINT
END


EDIT: By the way, David Briars suggestion of using a DEFINE should also work.

One final suggestion is to use:

SQL DB2 SET OPTIMIZATION OFF

This will cause aggregation to be done by WebFOCUS and DB2 should pass all values that meet the selection criteria. This has the same disadvantage as using PRINT, in that performance could be adversely affected for large result sets.

thanks Dan for the suggestions. Our file is huge here and performance is important. My issue is not so much that a particular field has no value. Rather, there is no record (or row) for a particular country value. For example, say, there is nothing for country China at all. China will not show up in the report.

If you have a ready cheap source (e.g., dimension table) that can provide the list of key values, MATCH FILE can be used to force in any missing key values.

The penalty paid is the merge phase of MATCH (which in this case should be tolerable), and the need to HOLD and TABLE from HOLD (which you may be doing regardless).

The other columns in the forced-in rows will be zero, blank, or MISSING, depending how they are defined.

a great idea, j. Yes, we have a dimension ready to use. This will work. I have to say, though, initially I was not doing a hold file. It was a straight TABLE FILE... SUM .. BY ...

But, it is a small price to pay.

Thanks all for all the wonderful suggestions.
