Average score for a given name within the current month - sql

Question

I have a table data set of customer service reps score per call for the current year and I'm trying to build a query to calculate the average score for a given name within a given month
Something like calculating the average score for Matt's calls for the month of January.
I've been trying but I'm a begginer at SQL so I'm having trouble.
So far I've got this:
Select avg("general score") as General_Score, avg("Re_score") as Re_score
from Voc2019
Where [Name] ="Matt"
This gives me a error type mismatch
Would greatly appreciate any help you can provide to me.
UPDATE:
the code now works but While this does work I still need to order by a given date, but I I want to use this sql string to retrieve the average for a month specified varying on the month I want from excel but it's not returning any results
For instance I want Avg score for Matt in January
Currently I got
Select avg([general score]) as general_score, ("Re_score") as Re_score
from Voc2019
Where [Name] ="Matt" and Score_Date = Month(2)

Answer 1

The main issue with your code is that you are using a string ("general score") when attempting to reference a field (this is likely producing the type mismatch error).
You haven't indicated the field in your table that contains the date for each record, and so selecting the appropriate set of records for a given month is impossible without this information.
However, to correct your current code, I would suggest the following:
select avg(voc2019.[general score]) as General_Score, avg(voc2019.re_score) as Re_score
from voc2019
where voc2019.name = "Matt"
If you were to identify the field containing the date for each record, you could calculate an average per month using something like:
select
dateserial(year(voc2019.date), month(voc2019.date), 1) as [Month],
avg(voc2019.[general score]) as General_Score,
avg(voc2019.re_score) as Re_score
from
voc2019
where
voc2019.name = "Matt"
group by
dateserial(year(voc2019.date), month(voc2019.date), 1)
The above assumes that your table voc2019 contains a field called date dating each record.
EDIT:
Since your date is actually stored as a Text field rather than a Date field, you can use the DateValue function to parse the text content into a date value.
Hence, to obtain the average score for Matt in January, you might use something like the following:
select
avg(voc2019.[general score]) as General_Score,
avg(voc2019.re_score) as Re_score
from
voc2019
where
voc2019.name = "Matt" and
month(datevalue(voc2019.date)) = 1 and
year(datevalue(voc2019.date)) = 2019
Alternatively, since your date is stored as text, you could use the like operator to match only dates in January, e.g.:
select
avg(voc2019.[general score]) as General_Score,
avg(voc2019.re_score) as Re_score
from
voc2019
where
voc2019.name = "Matt" and voc2019.date like "##-01-2019"

Answer 2

I am way more familiar with Oracle SQL syntax, but pretty sure the problem is with some simple MS Access syntax. Your literal string "Matt" which should be single-quoted as in 'Matt' and the square brackets are used to enclose a column identifier only when it contains a space.
Try:
Select avg([general score]) as General_Score, avg(Re_score) as Re_score
from Voc2019
Where Name = 'Matt'
