Select data out of scope --> how to get 'no data' (backendApi)

[krzohi]

Hi,

how to get  empty result of selecting not existing data?

I'm trying to integrate daterangepicker and in case selected date not exist in data i want to get empty report.

SELECTED DATE:    '1999-05-05'

DATA:

[0, 2020-01-01

1, 2020-02-02

2, 2020-03-03]

i tried:

self.backendApi.selectValues(0, [], false) --> all values on result
self.backendApi.selectValues(0, [999], false) --> error (number out of scope)
