I'm trying to extract Year only from a date field.

The field is PLANNED_END format - HYYMDS

The following statement below converts PLANNED_END to a date field PLANNED_EST2
format - 2009/12/08 09:00:00.

PLANNED_EST2/HYYMDS = HADD(PLANNED_END,'hh',-4, 8, PLANNED_EST2);

What command would be used to extract the year only from PLANNED_END...ex 2009
and place it in a field PLANNED_YEAR?

You need to use HDATE,

COMPUTE YOUR_DATE/YYMD =HDATE (PLANNED_END,'YYMD');
COMPUTE YEAR_ONLY/YY = YOUR_DATE;

This can be done in one line, using Date-Time function HNAME or HPART:

DEFINE FILE CAR
PLANNED_END/HYYMDS WITH COUNTRY = HINPUT(14, '20090509000000', 8, 'HYYMDS');
END

TABLE FILE CAR
SUM 
SALES
COMPUTE PLANNED_YEAR_ALPHA/A4 = HNAME(PLANNED_END, 'YEAR', 'A4');

COMPUTE PLANNED_YEAR_NUM/I4 = HPART(PLANNED_END, 'YEAR', 'I4');
BY COUNTRY

END

Thanks for the response. I added both COMPUTE statements after my Define file statement.

When I reference YEAR_ONLY field in my Print statement (line 34) I get the following errors.

Could the format be incorrect on the COMPUTE statements?

(FOC259) FIELDNAME EXCEEDS ITS MAXIMUM SIZE: COMPUTE YOUR_DATE
(FOC259) FIELDNAME EXCEEDS ITS MAXIMUM SIZE: COMPUTE YEAR_ONLY
0 ERROR AT OR NEAR LINE 34 IN PROCEDURE ADHOCRQ FOCEXEC *
(FOC003) THE FIELDNAME IS NOT RECOGNIZED: YEAR_ONLY

Francis, I'm getting the same error message for both Compute fields which is coded after the Define file and before the Table file statement.

(FOC259) FIELDNAME EXCEEDS ITS MAXIMUM SIZE: PLANNED_YEAR_ALPHA
(FOC259) FIELDNAME EXCEEDS ITS MAXIMUM SIZE:
PLANNED_YEAR_NUM

COMPUTE PLANNED_YEAR_ALPHA/A4 = HNAME(PLANNED_END, 'YEAR', 'A4');
COMPUTE PLANNED_YEAR_NUM/I4 = HPART(PLANNED_END, 'YEAR', 'I4');

Why do you have a DEFINE FILE statement? I need one to simulate a Date-Time (HYYMDS) field in the CAR file, but you already have a Date-Time (HYYMDS) field, PLANNED_END.

Verify that PLANNED_END is indeed a HYYMDS field.

Are you missing a semi-colon in the DEFINE or COMPUTE?

Error 259: The maximum size of a fieldname or alias is 66 characters. Reduce the size of the name

May be caused by a missing semi-colon or some other coding error, or if the field-name is too long.

Computes go within the TABLE FILE statement, not before - see my example.

Babinsky, I would strongly suggest reading/referencing the WebFOCUS Manual!

Here is a link to the Functions manual
Date and Time Functions

By checking this, you could have avoided the errors.
