I am in the process of adding empty report logic to some reports. Can I customize the message when there is no data to display? If so, how?

Thanks!

Oops. Sorry about that. I tried to post some HTML code after testing -IF &LINES EQ 0 GOTO ERRMSG, but it was rejected by the forum.

Examples of, one of the method:

TABLE FILE CAR
SUM SALES
 BY COUNTRY
WHERE COUNTRY CONTAINS '&CTRY'
ON TABLE HOLD
END
-RUN
-****************************************************************
-* If empty report then display message and exit,
-* else display the report.
-****************************************************************
-IF &RECORDS EQ 0 THEN GOTO :EMPTYRPT ELSE GOTO :DISPREPORT;
-:EMPTYRPT
-SET &MESSAGE='No data found for COUNTRY containing text: ' | &CTRY;
-HTMLFORM BEGIN


&MESSAGE



-HTMLFORM END
-GOTO :ENDREPORT;
-*
-:DISPREPORT
TABLE FILE HOLD
PRINT *
END
-GOTO :ENDREPORT;
-*
-:ENDREPORT
There are plenty of possible modifications of the method. For instance, you can -INCLUDE your "empty report message" page, instead of embedding HTML into FEX - this way you can reuse your "empty report message" page. etc., etc., ...
See also how it is solved within the CenturyCorp demo code. (e.g. salerank.fex)

Hope this helps
Grzegorz

rstull,
amother idea is a simple way you might like:
SET EMPTYREPORT = ON
and then if your &LINES is 0, you'll get just the heading and nothing else.

I tried that initially. But, several of the end users thought since the headings loaded, that there was more data to be displayed. I had the same result with setting it to off. The users thought the page was just loading slowly. My hope, with adding a message, is to clarify the situation for the end user.

Thanks!

ah, i see. here's what i do:
you could create a line in your heading, say line 2.
it is populated by an &var
and the &var is defaulted to empty
-SET &HEADLINE2 = ' ' ;
now, at the end of your fex,
-SET &HEADLINE2 = IF &LINES GT 0 THEN ' ' ELSE 'NOPE NO DATA FOR YOU TODAY';
then in your fex
HEADING
" STUFF"
" &HEADLINE2 "

Thanks for the idea. I tried it, but got the following error message:

0 ERROR AT OR NEAR LINE 19 IN PROCEDURE MEMFEX FOCEXEC *
(FOC002) A WORD IS NOT RECOGNIZED: EXEC
BYPASSING TO END OF COMMAND

Any ideas?

susannah,
Is this what you had in mind?

SET EMPTYREPORT=ON
-SET &EmptyHead = ' ';
TABLE FILE CAR
PRINT BODYTYPE
BY CAR
WHERE COUNTRY EQ 'INVALID'
ON TABLE HOLD
END
-RUN
-SET &EmptyHead = IF &LINES GT 0 THEN ' ' ELSE 'Sorry, there''s no data today.';
TABLE FILE HOLD
HEADING
"&EmptyHead"
PRINT *
ON TABLE SET STYLE *
TYPE=HEADING,
COLOR=RED,$
ENDSTYLE
END

Is there a way to do this without using a hold file?
Thanks,
Michael

This code came out of an old WebFocus Users Manual.... still seemed to work....

TABLE FILE CAR
HEADING
" "
PRINT SEATS DEALER_COST RETAIL_COST WARRANTY
BY CAR
WHERE COUNTRY EQ 'INVALID'
END
-RUN
-IF &LINES EQ 0 GOTO RPT2 ELSE GOTO REPTDONE;
-RPT2
-TYPE NO REPORT INFORMATION GENERATED
-RUN
-QUIT
-REPTDONE
-EXIT

Another option if you want to drop the message into a 'jacket' program that has the same look and feel is to do something along the following lines:

TABLE FILE MFDNAME
PRINT *
ON TABLE HOLD AS JACDAT FORMAT HTML
END
-IF &LINES EQ 0 GOTO EMPTRPT;
-RUN
-GOTO JCKT
-EMPTRPT
TABLE FILE SMALLFILE
"No data was found for the criteria entered"
PRINT
FIELD NOPRINT
ON TABLE HOLD AS JACDAT FORMAT HTML
END
-RUN
-JCKT
-HTMLFORM JCKTHTML
-EXIT

You then have an html file with the phrase
!IBI.FIL.JACDAT;
at the point in the html file where you want the phrase to appear..

We use this as a way of making the error message look more friendly and you can customize it however you need to. Also keeps the look and feel the same as the report data which would have dropped into that same jacket.

Mikel, yes exactly. you need the &LINES count so i don't see how to get it without creating a holdfile.
webfocuspgm, -TYPE won't display html code.
rstull, there's probably a typo somewhere in your code. it'll work. just keep tweaking. we're all giving you the same answer, essentially, just different flavors

proc
...
-IF &LINES EQ 0 THEN GOTO NODATA;
END
...

ENDSTYLE
END
-GOTO DONE
-NODATA
-INCLUDE ERRORPAGE
END

-DONE
Then we used the proc for errorpage

-* File ERRORPAGE.fex
TABLEF FILE REPORT
PRINT Report_ID NOPRINT
HEADING
"No data was extracted. Review your criteria and submit again"

ON TABLE SET ONLINE-FMT &fmt
ON TABLE SET EMPTYREPORT ON
ON TABLE SET PAGE-NUM OFF
ON TABLE SET STYLE *
UNITS=IN, PAGESIZE=&PSize, LEFTMARGIN=0.250000, RIGHTMARGIN=0.050000, TOPMARGIN=0.250000,
BOTTOMMARGIN=0.250000, ORIENTATION=LANDSCAPE, $

TYPE=REPORT, ORIENTATION=LANDSCAPE, $


END

Report table was a very small table that we used - create a table with one row of data
