![]() These functions return their values in DATE data type. To return just the current date, use CURRENT_DATE or CURDATE. To change the default date format, use the SET OPTION command with the DATE_FORMAT, YEAR_OPTION, or DATE_SEPARATOR options. To specify a different date format, use the TO_DATE function. For example, in an American locale, in a European locale, in a Russian locale. CURRENT_DATE in Display mode returns the current local date in the default format for the locale. CURRENT_DATE returns the current local date for this timezone it adjusts for local time variants, such as Daylight Saving Time.ĬURRENT_DATE in Logical mode returns the current local date in $HOROLOG format for example, 62970. CURRENT_DATE takes no arguments and returns the date as type DATE. SearchCursor (tbl, "START_DATE", sql ), sep = "\n" ) (datetime. datetime ( 2018, 7, 30, 0, 0 ), ) > # print records where START_DATE within 90 days of now > sql = "CURRENT_DATE - START_DATE > print ( *arcpy.

CreateTable_management (sgdb, "tbl" ) > arcpy. > from datetime import datetime as dt, timedelta as td If you want to select all records whose START_DATE is within 90 days of the current date, all you need is my suggestion above: "CURRENT_DATE - START_DATE > # python3 > import arcpy ![]() You can change this by adding 90 to second date listed. In both solutions, it assumes you are interested in only 90 days before the given date. This will return all dates between Jand Oct 22, 2017. Start_date >= date '' - 90 and start_date <= date '' You can easily substitute CURRENT DATE with any date (see below as example).Īs for the second one here it could be any date: That means for today this would return values like (EXTRACT (MONTH FROM Start_Date ) - 1 ) * 30 + EXTRACT (DAY FROM Start_Date ) BETWEEN ( (EXTRACT (MONTH FROM CURRENT_DATE ) - 1 ) * 30 + EXTRACT (DAY FROM CURRENT_DATE ) - 90 ) AND ( (EXTRACT (MONTH FROM CURRENT_DATE ) - 1 ) * 30 + EXTRACT (DAY FROM CURRENT_DATE ) ) It is not perfect since it assumes each month has exactly 30 days. Or are you trying to find all dates that are 90 days within a provided past date? Those two problems would have different solutions.įor the first question. Are you interested in finding all calendar dates that fall within 90 days of this time each year. It also has a problem with dates that fall in January as those records are not selected by add +3 from current month (10).Ĭan you combine EXTRACT(DAY.) AND EXTRACT(MONTH.) in the same query? I've been trying but keep getting a syntax error. This is using the MONTH field, and it works to a degree, but is not quite precise. (EXTRACT(MONTH FROM Start_Date) >= EXTRACT(MONTH FROM CURRENT_DATE)) and (EXTRACT(MONTH FROM Start_Date) <= EXTRACT(MONTH FROM CURRENT_DATE)+3) ![]() Is there a way to use the day & month of the "Start_Date" field to determine if the Start_Date is within 90 days of today's date or Current Date. The issue I have is that the Date field (DD/MM/YYYY) I am using, I can only use the DD/MM portion of this field as the year part is not a future year date. I have a feature class in a fgdb (ArcMap 10.6) and I want to add a definition query which shows me records that have a 'Start_Date' within 90 days of the current date. ![]()
