how to get data until the next 1 number - sql

I have a date table where I have assinged business days. I need to get business from, for example, 1-20 before the next number 1. How can I do that? Here is a smaller verion of my table:
Date Day BusinessDays
2015-05-01 Friday 1

I need to get data from 1 to 20 business days and don't include the numbers that starts again from one (for example exclude rows that have * in front). This needs to be dynamic. Since DayName will change for every number so I can't include that in my where clause.

Let me assume that you have a date in mind, so you want everything from that date to the next "1".
select t.*
from datetable t
where t.date >= '2015-05-01' and
t.date < (select min(t2.date)
from datetable t2
where t2.date > '2015-05-01' and
t2.businessdays = 1
);

Create a counter based on days of the week, Fri-Mon treated as a bucket

Today/Getdate is always going to be the starting date. A counter starts at 0; let's call it TheResult. If the day is Friday/Saturday/Sunday/Monday, then they all receive the same number in the counting process. The accrual picks back up on Tuesday.

What would the sql code need to be to achieve the values in the TheResult column?
I'm not sure how to approach the problem because of the Fri-Mon bucket of days, so I have not made any progress. I've tried finding similar questions asked using Google, but it seems I'm searching for the wrong keywords to find the answer to my question.

Repeat the day of the week for each time inside a string

I have a table with just one column and about 3000 rows that follows the same pattern. I want to include the days of the week at the beginning of the string for each TIME inside the same string in the row.
Original table :
DATA_TIME_COMBINATION
Monday 3 am HM, 5 am HC, 10 pm HX
Saturday AB 6 am, WE 5 pm
Sunday Friday AN 50 TU,FG 55 RE, DC 56 JJ
Tuesday 10 am, 5 am, 1 am
Wednesday 12 pm-9 pm- 1 am
Results needed :
DATA_TIME_COMBINATION
Monday 3 am HM, Monday 5 am HC, Monday 10 pm HX
Saturday AB 6 am, Saturday WE 5 pm
Sunday Friday AN 50 TU, Sunday Friday FG 55 RE, Sunday Friday DC 56 JJ
Tuesday 10 am, Tuesday 5 am, Tuesday 1 am
Wednesday 12 pm- Wednesday 9 pm- Wednesday 1 am
Thanks in advance!
seems you want replace the comma with a comma and the first word at beginning of the string
select replace(DATA_TIME_COMBINATION, ',',
concat(',', substr(DATA_TIME_COMBINATION,1,charindex(' ', DATA_TIME_COMBINATION)-1)))
from my_table
Once you know the character and days.
Then it'll become a simple replace.
One cross apply for the weekdays.
A second for a character in place.
SELECT
REPLACE(REPLACE([DATA_TIME_COMBINATION], chr, chr+' '+days+' '),' ',' ') as DATA_TIME_COMBINATION
FROM mytable AS t
CROSS APPLY (
SELECT STRING_AGG(value, ' ') days
FROM STRING_SPLIT(
LEFT([DATA_TIME_COMBINATION], PATINDEX('%[a-z] [0-9]%', [DATA_TIME_COMBINATION])), ' ') spl
WHERE value LIKE '%day'
) ca1
CROSS APPLY (
SELECT
chr = SUBSTRING([DATA_TIME_COMBINATION], PATINDEX('%[^A-Za-z0-9 ]%', [DATA_TIME_COMBINATION]), 1)
) ca2;
DATA_TIME_COMBINATION
Monday 3 am HM, Monday 5 am HC, Monday 10 pm HX
Saturday AB 6 am, Saturday WE 5 pm
Sunday Friday AN 50 TU, Sunday Friday FG 55 RE, Sunday Friday DC 56 JJ
Tuesday 10 am, Tuesday 5 am, Tuesday 1 am
Wednesday 12 pm- Wednesday 9 pm- Wednesday 1am

Skip Holidays in Business day Table

I am using the following script to determine what the business days are for each particular month.
DECLARE #startdate DATETIME
SET #startdate ='20170401'
;
WITH bd AS(
SELECT
DATEADD(DAY,
CASE
(DATEPART(WEEKDAY, DATEADD(MONTH, DATEDIFF(MONTH, 0, #startdate), 0)) + ##DATEFIRST - 1) % 7
WHEN 6 THEN 2
WHEN 7 THEN 1
ELSE 0
END,
DATEADD(MONTH, DATEDIFF(MONTH, 0, #startdate), 0)
) AS bd, 1 AS n
UNION ALL
SELECT DATEADD(DAY,
CASE
(DATEPART(WEEKDAY, bd.bd) + ##DATEFIRST - 1) % 7
WHEN 5 THEN 3
WHEN 6 THEN 2
ELSE 1
END,
bd.bd
) AS db,
bd.n+1
FROM bd WHERE MONTH(bd.bd) = MONTH(#startdate)
)
SELECT * INTO #BD
FROM (
SELECT 'BD'+ CAST(n AS VARCHAR(5)) AS Expected_Date_Rule, bd AS Expected_Calendar_Date
from bd
) AS x
The result of this table works fine. Bd is the the calendar days for the particular month and n is the business day number. The script does its job of not counting the weekend as a business day.

But then I notice that a potential issue will occur in July where the output will count the 4th of July as BD2 when it should be counted as BD3. Some had created a holiday table that is updated with all the holidays (excuse the bad spelling).

I was thinking there may be some way I can update my script to check the holiday table and skip the holiday and dont count it as a business day. Any tips?

Oracle SQL - Same day last year (leap year proof)

I'm looking to find the same day last year in oracle sql. For example Wednesday, March 16, 2016 would be Wednesday, March 18, 2015 for last year. So the closest day.
The following code worked good until the current leap year and broke after Feb 29th 2016.
this was my old statement which does not work for all dates:
NEXT_DAY(TRUNC(ADD_MONTHS(date, -12), 'iw')-2, TO_CHAR(date, 'DY'))
Simply subtract 7*52 = 364 days instead :-)
I think this may be correct

TO_NUMBER (TO_CHAR (SYSDATE - (LEVEL - 1), 'D'))

So, I want to group these values under weeknumber which must start from 1 for WeekSerial number ranges from 1 to 7.
NOTE: The week day starts from Monday to Sunday so its numbered from 1 through 7. i.e 1=Monday, 2=Tuesday and so on...!
Update:
INSERT INTO #Temp(KioskCount,KioskAmount,KioskAverage,WeekDate,WeekDays,WeekSerial)
Select COUNT(tq.quoteid)KioskCount,
SUM(tq.PriceQuote) [KioskAmount],
SUM(tq.PriceQuote) / COUNT(tq.QuoteID) [KioskAverage],
CONVERT(VARCHAR(10),tq.DateCreated,101)WeekDate,
DATENAME(WEEKDAY,tq.DateCreated)WeekDays,
CASE When DATEPART(WEEKDAY,tq.DateCreated)-1=0 THEN 7 ELSE DATEPART(WEEKDAY,tq.DateCreated)-1 END as WeekSerial
from tbl_Quotes tq
where
tq.QuoteStatusID <> 12 --remove void transactions
group by CONVERT(VARCHAR(10),tq.DateCreated,101),DATENAME(WEEKDAY,tq.DateCreated),DATEPART(WEEKDAY,tq.DateCreated)-1
order by 4
It is unclear actually what did you expect
You have already a WeekDate filed i think the date are correct and based on that you are filled your weekday field
then simply you can loop through the dates and update your week number using the WeekDate
i can provide an example with that
DECLARE #DATE DATETIME
DECLARE #count int
DECLARE #i int
SET #i=56// you can find your first id via query too
SET #count=(select COUNT(WeekDays) from tablename)
WHILE #i<=#count
BEGIN
SET #DATE =(select WeekDate from tablename where ID=#i)
update tablename set WeekNumber=(
SELECT DATEPART(WEEK, #DATE) -
DATEPART(WEEK, DATEADD(MM, DATEDIFF(MM,0,#DATE), 0))+ 1 AS WEEK_OF_MONTH)
where ID=#i
set #i=#i + 1
END;
it will update all your weeknumber field with corresponding number
Probably this helps you:
First you need to check the first of the day in your database
SELECT ##DATEFIRST
By default SUNDAY is first day of week (US). So you need to change it to 1 (Monday)
SET DATEFIRST 1
More inforamtion about SET DATEFIRST
In SQL Server by using DATEPART built-in function you can get the number of week in a year
SELECT DATAPART(WEEK, WeekDate)
Also you can get YEAR of your selected datetime
SELECT DATAPART(YEAR, WeekDate)
If you run these two queries for your first row (Let's say Week number 1)
SELECT DATEPART(WEEK, '2012-03-01 00:00:00.000') -- Output = 10
SELECT DATEPART(YEAR, '2012-03-01 00:00:00.000') -- Output = 2012
But this week should be your week number 1.
So you can easily subtract 2012 from your YEAR then multiply it by 52 (because we have 52 weeks in a year)
Substract 9 from your WEEKNUMBER
Add the numbers you get from above
(YEAR - 2012) * 52 + (WEEK - 9)
So by running this you can get the actual result
SELECT (DATEPART(YEAR, WeekDate) - 2012) * 52 + DATEPART(WEEK, WeekDate) - 9 AS WeekNumber
FROM yourTable
