Yes this does work in PostgreSQL (assuming the column "date" is of datatype date
)
Why don't you just try it?
The standard ANSI SQL format would be:
SELECT Table.date
FROM Table
WHERE date > current_date - interval '10' day;
I prefer that format as it makes things easier to read (but it is the same as current_date - 10
).
http://www.postgresql.org/docs/current/static/functions-datetime.html shows operators you can use for working with dates and times (and intervals).
So you want
SELECT "date"
FROM "Table"
WHERE "date" > (CURRENT_DATE - INTERVAL '10 days');
The operators/functions above are documented in detail:
My understanding from my testing (and the PostgreSQL dox) is that the quotes need to be done differently from the other answers, and should also include "day" like this:
SELECT Table.date
FROM Table
WHERE date > current_date - interval '10 day';
Demonstrated here (you should be able to run this on any Postgres db):
SELECT DISTINCT current_date,
current_date - interval '10' day,
current_date - interval '10 days'
FROM pg_language;
Result:
2013-03-01 2013-03-01 00:00:00 2013-02-19 00:00:00
Just generalising the query if you want to work with any given date instead of current date:
SELECT Table.date
FROM Table
WHERE Table.date > '2020-01-01'::date - interval '10 day'
The suggested answers already seem to solve the questions. But as an addition I am suggesting to use the NOW() function of PostgreSQL.
SELECT Table.date
FROM Table
WHERE date > now() - interval '10' day;
Additionally you can even specifiy the time zone which can be really handy.
NOW () AT TIME ZONE 'Europe/Paris'
