ydn db - IndexedDB using YDN-DB: How to query object store on multiple filters -



ydn db - IndexedDB using YDN-DB: How to query object store on multiple filters -

working on offline html5 project, have next store:

outreach_answers = { name: 'outreach_answers', keypath: ['device_unique_id', 'outreach_id', 'question_id'], indexes: [ { keypath: 'outreach_id' }, { keypath: 'section_id' }, { keypath: 'question_id' }, { keypath: 'answer' } ] }

i need create query such this:

select records outreach_answers question_id = 12 , section_id = 2 , outreach_id = 'ab-56'

most of methods have been able utilize (e.g. db.get(), db.values() or db.from()...where().list()) seem quite restrictive.

of these, lastly method seemed promising, until required run query should filter on question_id, section_id , outreach_id @ same time.

thank in advance!
