For an embedded HSQL database the query goes like this:
SELECT * FROM "Your Table" WHERE DATEDIFF('day', CURRENT_DATE, "Date Field")
BETWEEN -10 AND 10
Replace the double quoted names with the actual names of your table and
field.
Quicker should be (if an index exists on "Date Field":
select *
from "Your Table"
WHERE "Date Field" BETWEEN
DATEADD('day', -10, CURRENT_DATE and DATEADD('day', +10, CURRENT_DATE)
Because with this query an index will be used, and with the
datadiff-query, no index will be used.
