如何在 ABAP CDS 视图中获取当前年份

Question

Is there any way to get current timestamp or current date? SQL syntax is date.now() but it doesn't work in ABAP CDS. Is there any solution without parameters?

Answer 1

In 7.50 you have tstmp_current_utctimestamp() . It may be used to compare with other timestamps, leading to a need to convert typical date and time fields. Example:

// As our system is set to UTC already, these cast and calculation are OK awaiting ABAP 7.51. Add a day if time is 24:00.
case resb.bdztp when '240000' 
                then cast( cast( cast( concat( DATS_ADD_DAYS( resb.bdter, 1, 'NULL'), '000000' ) as abap.numc(14) ) as abap.dec( 15, 0 ) ) as timestamp )
                else cast( cast( cast( concat( resb.bdter, resb.bdztp )                          as abap.numc(14) ) as abap.dec( 15, 0 ) ) as timestamp )
end as RequirementDateTimeUTC,

Consumption:

// Seconds since Requirement Date & Time for view isOverdue. 
tstmp_seconds_between( resb.RequirementDateTimeUTC, tstmp_current_utctimestamp(), 'NULL') as SecondsSinceReqDateTimeUTC,

Answer 2

The session variable $session.system_date is used in a CDS view to provide direct access to the current system date.

There is not yet a session variable for the current system time and a CDS view can be given an appropriate input parameter instead. The special annotation @Environment.systemField makes it possible to pass the value of the ABAP system field sy-uzeit to a parameter of this type.
