Basic Functions

when i try to use sum function in basic function i don't have it.
is there a way to add functions in basic function?, do i have to change some settings?
i only have few functions like count, maximum, minimum and ....
note that my database thoroughly has coherence with this functions.

What database software & version are you querying?

When you say "basic function," you mean you can't see Sum in the dropdown for a Summarization line in the query editor?

1- MySQL 8.0.35
2-YES, EXACTLY

Check that the metadata for the table is set correctly, in particular that the column(s) you want to summarize are set to a numeric type. The arithmetic aggregations won't display if no columns in the table are valid sources, as far as Metabase is concerned.

I have columns in my table that cells can be summed.
I did not get the right answer.

Did you check the table metadata?

Sorry to join so late, but what options are you seeing?
