Can we use substring function in CDS view where clause

[Husain]

My requirement is to fetch the current year by using the system date variable in the CDS view.

I am using the substring function along with $session.system_date field in the where clause but it is not allowing me to use it.

Can someone guide me on how to use it in the where clause?

Hi husainsd

please check below code you can able to understand,

define view ZK_I_DATE_FUNC as select from ZK_I_DATE_FUNCTIONS

{

Id,

Name,

StartDate,

EndDate,

//date functions

DATs_is_valid(StartDate) as s_Date1,

dats_is_valid(EndDate) as e_Date1,

dats_days_between(StartDate, EndDate) as betweenS,

dats_add_days(StartDate, 7, 'NULL') as ad_days,

dats_add_months(StartDate, 2, 'FAIL') as ADD_MONTHS,

DATS_ADD_DAYS(StartDate, 4, 'INITIAL') as option4,

DATS_ADD_DAYS(StartDate, 2, 'UNCHANGED') as option5

} where StartDate = $session.system_date

Hi Kiran,

I need to extract the current year from the system.date. In the where clause something like

year= system.date+4?

Can we do this?
