Is it possible to combine two datatable from multiple essql filters

Elastic Stack Kibana
1

Hi, I have a data source like below: -

TYPE VALUE
A 123
A 234
B 890
A 789
B 085

I need to pull the latest record for each type i.e. there will be two rows in the result : -

A 123
B 890

I think I cannot do it with elasticsearch sql(please correct me if I am wrong). If not, can I have two essql filters in my expression and somehow combine them? The two essql filters will be : -

SELECT TYPE, VALUE FROM SOURCE WHERE TYPE = A ORDER BY @timestamp DESC LIMIT 1

SELECT TYPE, VALUE FROM SOURCE WHERE TYPE = B ORDER BY @timestamp DESC LIMIT 1

Is it possible?

Thanks a lot in advance.

Hi @tangkalo, since you've asked this question in #elastic-stack:kibana section, I assume you are using canvas and this is a question about visualizing your data?

I don't think it is possible to combine two data tables into a single table this way.
As a presentation alternative, I'd suggest to create two separate canvas metric charts and configure each two display last values for its own type.

Thanks for the suggestion. Yes, it's in canvas. By metric charts, do you mean the Metric element?

On the other hand, I am also thinking of manually creating a table and populating it with customized values. I have been looking at Markdown element but haven't been able to find the syntax that allows me to create a table.

Yes!
