As of December 1, 2020, Focal Point is retired and repurposed as a reference repository. We value the wealth of knowledge that's been shared here over the years. You'll continue to have access to this treasure trove of knowledge, for search purposes only.

New TIBCO Community Coming Soon
In early summer, TIBCO plans to launch a new community—with a new user experience, enhanced search, and expanded capabilities for member engagement with answers and discussions! In advance of that, the current myibi community will be retired on April 30. We will continue to provide updates here on both the retirement of myibi and the new community launch.

What You Need to Know about Our New Community
We value the wealth of knowledge and engagement shared by community members and hope the new community will continue cultivating networking, knowledge sharing, and discussion.

During the transition period, from April 20th until the new community is launched this summer, myibi users should access the TIBCO WebFOCUS page to engage.

I would like to add a where clause to my report similar to
sqlserverDate_Field GE TIME_RIGHT_NOW - 24 hours

My usual method is to use &YYMD - 1, and this works for our AS400 as the dates are stored as numbers anyhow.

I'm sure this is easy for you fellas. Thank you for your patience.

It is basically the same logic as you are doing:
-SET &CMPDT=AYMD(&YYMD,-1,'I8YYMD');
-SET &CMPDTTM=EDIT('&CMPDT.EVAL','9999/99/99')|' '| &TOD;

I haven't tested this, you may have to adjust the syntax.

This is what I do to manipulate date-time values for SQL selection criteria:

-SET &CUR_DTTM = &DATEYYMD | ' 00:00:00';

-SET &NEW_DTTM = HCNVRT(HADD(HINPUT(14, '&CUR_DTTM.EVAL' , 14, 'HYYMDS'), 'HOUR', -24, 8, 'HYYMDS'), '(HYYMDS)', 20, 'A20');

-TYPE &CUR_DTTM &NEW_DTTM


To use the Date-Time functions in Dialogue Manager, you need to convert the string to a Date-Time field and then convert it back to a string after the function is processed.

It looks daunting, but if you look at each part of the DM line of code, it's easy:

HINPUT(inputlength, 'inputstring', length, outfield) - Converts an Alphanumeric String to a Date-Time Value
HADD(value, 'component', increment, length, outfield) - Increments a Date-Time Value
HCNVRT(value, '(fmt)', length, outfield) - Converts a Date-Time Value to Alphanumeric Format

...
WHERE DATE_TIME_COLUMN GE '&NEW_DTTM'
...

Francis,
I'm using the -set's that you mentioned, but we're getting an error on this line..

WHERE DELIVERED GE '&NEW_DTTM';

(FOC36346) INCORRECT USE OF DATE-TIME FIELD OR CONSTANT

The field is defined as 'HYYMDI' in the master file, if that makes a difference.

When we do a set echo on, the following shows up in the browser...
WHERE DELIVERED GE '2008/05/27 00:00:00 ';

Is there something I'm missing?

Try WHERE DELIVERED GE ('&NEW_DTTM');

Prarie,
Thank you for your quick response!

We're getting the same error.

The echo shows
WHERE DELIVERED GE ('2008/05/27 00:00:00 ');

It looks like a valid date to me. Wink

You MAY need to append '.000' for milliseconds to the end of the date-time, eg. '2008/05/27 00:00:00.000'.

The WHERE statement:

WHERE DT1 GT DT('&NEW_DTTM1');

(Forget about the .000).

-SET &ECHO=ALL;
-SET &CUR_DTTM = &DATEYYMD | ' 00:00:00';

-SET &NEW_DTTM1 = HCNVRT(HADD(HINPUT(14, '&CUR_DTTM.EVAL' , 14, 'HYYMDS'), 'HOUR', -24, 8, 'HYYMDS'), '(HYYMDS)', 20, 'A20') ;
-SET &NEW_DTTM2 = HCNVRT(HADD(HINPUT(14, '&CUR_DTTM.EVAL' , 14, 'HYYMDS'), 'HOUR', -22, 8, 'HYYMDS'), '(HYYMDS)', 20, 'A20') ;
-SET &NEW_DTTM3 = HCNVRT(HADD(HINPUT(14, '&CUR_DTTM.EVAL' , 14, 'HYYMDS'), 'HOUR', -20, 8, 'HYYMDS'), '(HYYMDS)', 20, 'A20') ;

DEFINE FILE CAR
DT1/HYYMDIA = IF COUNTRY EQ 'ENGLAND' THEN DT(&NEW_DTTM1) ELSE IF COUNTRY EQ 'JAPAN' THEN DT(&NEW_DTTM2) ELSE DT(&NEW_DTTM3);
END

TABLE FILE CAR
PRINT
COUNTRY
DT1
WHERE DT1 GT DT('&NEW_DTTM1');
ON TABLE HOLD
END

Good work on the DT() Francis.
Thanks again!

Believe it or not, this is actually a good example of where the report painter does a good job. If you run it through that, it should put the DT() in there for you. Also, for what it's worth, in my experience, the DT() function only works with static (amper) values -- NOT with columns/defines... I believe it will actually throw an error if you try anything else.

Glad you got it working though.
