Canvas ESSQL current date - 30 days query

Elastic Stack Kibana
1

Hello! I'm trying to make a relative date query in elasticsearch SQL. I have this code:

SELECT * FROM index WHERE date > CURRENT_DATE - INTERVAL '30' DAY

Which seems to be correct. However when I run it, it gives the following error:

[essql] > Unexpected error from Elasticsearch: [parse_exception] failed to parse date field [2019-07-02T00:00Z] with format [HH:mm yyyy-MM-dd]: [Text '2019-07-02T00:00Z' could not be parsed at index 2]

Can you please help me understand this. Is there a way to reformat the date format output by 'CURRENT_DATE'? Do I need to reformatting the way I store my dates in elasticsearch?

This is driving me up the wall. Any help is hugely appreciated.
Thanks

@samgs you are right and thank you for posting your question. This is a bug. We do not set a specific format in the range filter we create and, implicitly, Elasticsearch takes the format of the date constant we pass in resulting from the CURRENT_DATE - INTERVAL '30' DAY calculus. And that format is yyyy-MM-dd'T'HH:mm:ss.SSSV.

I've created an issue and I'll take care of it: https://github.com/elastic/elasticsearch/issues/45139.

I don't think there is any workaround at the moment other than using the default format for your date fields.

Where might we find doc on ES SQL and more specifically what functions have been implemented in what version and howto use them?

@stefws this is our main page for the list of functions available in ES SQL: https://www.elastic.co/guide/en/elasticsearch/reference/7.x/sql-functions.html

Regarding the specific versions, you'd have to look for the release notes of those versions. It might also help the github issues created for features/bugs, where the associated PR that implemented/fixed the feature/bug has version labels.
