Oracle: Days between two date and Exclude weekdays how to handle negative numbers
(2 answers)
Closed 4 years ago.
I am trying to calculate the days between two different dates. If d1 is on saturday or sunday it should not take calculate those days. d2 is the system date.
the formula i have is
(ROUND((d2-d1)-DECODE(SIGN(TO_CHAR(d2,'D')-
TO_CHAR(d1,'D')),-1,2,0)+DECODE(TO_CHAR(d1,'D'),7,1,0)-
DECODE(TO_CHAR(d2,'D'),7,1,0),2)) AS "DAYS",
this would give me 1 days from friday to sunday which is correct, but 7 days from sunday to last sunday instead of 5. anyway i can improve on this formula, or is there a simpler one i can use?

I Need to find out the next business in oracle if the todays date is holiday. There are two different scenarios, need help in writing the logic for these scenarios at once.
If the todays date is 1/17/2022, since it is holiday(Martin Luther King Day) i want to show the date as 1/18/2022 in the output which is nothing but next business day.
If the todays date is 05/31/2021, since it is holiday(Memorial Day), at the time next business falls into next month 01/06/2021. Since it is falling into next month, i want to show the previous business day of holiday 5/28/2021 in the output.

Can someone let me know a simple way to get # of days in a month in HIVE SQL based on current_date.
e.g. 2021-02-16 = 28 days, 2021-06-30 = 30 days etc
Use
day(last_day(current_date))
last_day(date) returns last day date, day(date) returns day part of the date, int

How to set monday as first day of week in SQL Server
(4 answers)
Closed 2 years ago.
I need to add a column to show the week number of the year in my procedure.
By default the SQL Server considers the week starts as Sunday and shows the week number.
But I need to calculate the week number starts from Saturday.
Code:
select datepart(week,'11-july-2020')
Output I get:
28
Output I need:
29
It should start considering from the week starts as Saturday and ends on Friday.
You can use DATEFIRST:
SET DATEFIRST 6;
select datepart(week,'11-july-2020');
It allows you to set the first day of the week to a number from 1 through 7, where 1 is Monday and 7 is Sunday.
