But if we use it with the - sign, then it will be added to the date. If we use a negative value with the + sign, then the specified number of days will be subtracted from the date. In PostgreSQL, we can use the + operator to add one or more months to a date. ![]() We can also perform date arithmetic with negative values. This also works in plural form: SELECT date '' + interval '5 days' In PostgreSQL there are basically 2 functions to do the same, as we have both datepart and extract: SELECT currentdate AS ACTUALDATE, EXTRACT (DAY FROM currentdate) AS ACTUALDAY, EXTRACT (MONTH FROM currentdate) AS ACTUALMONTH, EXTRACT (YEAR FROM currentdate) AS ACTUALYEAR. We can also do it like this: SELECT date '' + integer '5' īy specifying an integer of 5, five days were added to the date.Īnother way to do it is to specify an interval: SELECT date '' + interval '1 day' Add 18 years to the date in the BirthDate column, then return the date: SELECT LastName, BirthDate, DATEADD (year, 18, BirthDate) AS DateAdd FROM Employees Try it Yourself. ![]() Here are some examples that demonstrate the various options for specifying the number of days to add to the date. But I searched and come to know that there is no such function provided by PostgreSQL. ![]() We have a few options when it comes to specifying the actual number of days. 1) Get the current date To get the current date and time, you use the built-in NOW () function. But I searched and come to know that there is no such function provided by PostgreSQL. The + operator allows us to add one or more days to a given date in PostgreSQL.
