If you were to perform the query through code, then you could ouput a comma-separated file yourself, similar to following:
----------
Dim dbs as database
dim rst as recordset
set dbs = currentdb
set rst = dbs.recordset("SELECT Record_ID, thisField, that field FROM thisTable WHERE thisField > 5")
if rst.recordcount < 1 then
msgbox "No records found"
set rst = nothing
set dbs = nothing
else
rst.movelast
rst.movefirst
while rst NOT EOF 'Check this line
' output each line to atext file here
wend
endif
set rst = nothing
set dbs = nothing
----------
