So in order to get specific type of delivery for the last 3 months I was thinking to get today's date and convert it to 01/mm/yyyy format and ref it with the delivery month in the table to get least 3 month including. If within the same year, you can use Date. It takes into account the fact that DATEDIFF() computes the difference without considering what month or day it is (so the month diff between 8/31 and 9/1 is 1 month) and handles that with a case statement that decrements the result. Table 9. , for the Oracle database: sale_date >= TRUNC (sysdate) AND sale_date < TRUNC (sysdate + INTERVAL '1' DAY) Another common obfuscation is to compare dates as strings as shown in the following PostgreSQL example:The trick here is to get the first day of the next month which will always be 01-NextMonth-Year.
