Select / EXTRACT query

Hello,
I save my gas meter "gasmeter" readings together with time and date "time" to my MariaDB "gas".
With the following query code:

Select
    EXTRACT(DAY FROM time),
    MAX(gasmeter)-MIN(gasmeter) AS "gasmeter"
From gas
WHERE
    MONTH(time) = {{payload}}
Group By CAST(time AS DATE);

in a template node I'm able to retrieve my data as daily consumption in mm² for one month and use it on my dashboard. "{{payload}}" comes from a dropdown node (1 through 12) for each month.
Is there a way to change the "MONTH(time) = {{payload}}" condition into a "YEAR_MONTH" condition, so I can use my saved data for longer than 12 months?
Thank you in advance.

You will need to restructure your table to hold yr_month as a string and you will need to populate the ur_month field from time when you write the record.

It isnt clear how you save the date time .. does the date include the year ?
can you show us a few records of the db ?

if you do have a year in the date ..

WHERE
    MONTH(time) = {{payload}} AND YEAR(time) = '2021'

A possibility is to define a view

CREATE VIEW daily_consumption AS SELECT
    EXTRACT(YEARMONTH FROM time) as yyyymm , EXTRACT(DAY FROM time) as dd,
    MAX(gasmeter)-MIN(gasmeter) AS "gasmeter"
FROM gas
GROUP BY EXTRACT(YEARMONTH FROM time), EXTRACT(DAY FROM time);

And pseudo node-red topic to retrieve the data for your chosen day:
select * from daily_consumption where yyyymm = msg.yyyymm and dd = msg.dd

Wow, thanks for your quick answers. I'm going to have lots of fun trying them out.
@UnborN: I'd thought of "WHERE / AND" but I couldn't find any code to separate the dropdown payload into month and year. This is what my db looks like:

ID     time                      gasmeter
3369   2020-11-01 06:01:21       739.720
3370   2020-11-01 06:03:23       739.725

Thank you all again

a "dropdown" ? using the dropdown ui node ?
why not use the Date picker ui node and then a Change node to split the date to year, month, day

Example:
