HPART(datetime, 'component', output)

Example: Retrieving the Day Component in Numeric Format (Reporting)

HPART retrieves the day in integer format from the TRANSDATE field:

TABLE FILE VIDEOTR2
PRINT CUSTID TRANSDATE AS 'DATE-TIME' AND COMPUTE
DAY_COMPONENT/I2 = HPART(TRANSDATE, 'DAY', 'I2');
WHERE DATE EQ 2000;
END

The output is:

CUSTID	DATE-TIME	DAY_COMPONENT
1237 1118	2000/02/05 03:30 2000/06/26 05:45	5 26

Example: Retrieving the Day Component in Numeric Format (Maintain)

HPART extracts the day in integer format from DT1:

MAINTAIN FILE DATETIME
FOR 1 NEXT ID INTO STK;
COMPUTE
DAY_COMPONENT/I2 = HPART(STK.DT1,'DAY',DAY_COMPONENT);
TYPE "STK(1).DT1 = <STK(1).DT1";
TYPE "DAY_COMPONENT = <DAY_COMPONENT";
