SQL 2012 :: How To Calculate Date Difference In Months
Jan 23, 2015
I would like to calculate difference between end_date and current date in Months.And also how we can calculate the sum of difference in months between start_date and end_date for each ID?
CREATE TABLE datedifference (
id INT
,start_date INT
,end_date INT
)
INSERT INTO datedifference VALUES (10,20091202,20100629)
INSERT INTO datedifference VALUES (20,20071202,20090330)
INSERT INTO datedifference VALUES (30,20051202,20101031)
I have already seen stored procedures that can calculate a difference in dates, excluding the weekends. Any extension of such a SQL query to exclude not only weekends, but other dates as well. We have a table of "holidays" (not necessarily standard holidays), and I am wondering if there is a way to exclude them from the calculation.
Basically I want to calculate the time spent by S_Users on a particular S_ACTV_CODE:
- S_ACTV_CODE_PREV means the previous active records.
- S_START_TIME is the time of S_DATETIME when a S_ACTV_CODE starts
- S_END_TIME is the time before a S_ACTV_CODE changes to another S_ACTV_CODE
- For the first record, S_ACTV_CODE is null, so there is no S_ACTV_CODE_PREV, so S_ACTV_CODE_PREV is NULL
- For the second record S_ACTV_CODE has some value, but S_ACTV_CODE_PREV is NULL for first record. So second record S_ACTV_CODE_PREV is also NULL
- For the last record (means S_ACTV_IND = 1), the user is currently working on it and S_ACTV_CODE is not changed. So S_END_TIME is a open time and we want to keep it as NULL
I have a table with appdt as first appointment date and the another record for the same customer# has follow up appointment.
Each customer is uniquely identified by a customer#
I need to find out if the customer came back after 200 days or more when the first appointment date was between jan12014 and Aug 31 2014. I am only interested in first follow up appointment after 30 days or more.
I have a query to run a report where the results has a column named “Due Date” which holds a date value based on the project submission date.Now, I need to add 4 columns named, “45 Days Expectant”, “30 Days Overdue”, “60 Days Overdue” and “90 Days Overdue”.I need to do a calculation based on the “Due Date” and “System (I mean default computer date) Date” that if “System Date” is 45 days+ to “Due Date” than put “Yes” in “45 Days Expectant” row.
Also, if “Due Date” is less than or equal to system date by 30 days, put “Yes” in “30 Days Overdue” and same for the 60 and 90 days.how to write this Case Statement? I have some answers how to do it in SSRS (Report Designer) but I want to get the results using T-SQl.
I have a start date saved and an end date saved but when I query I only want to return the amount of months that have elapsed between the two, any idea?
I have a database of the table payments and I want to create another table with the olds payments (18 months past) a have a field with the payment date date_pay. How I can do that?
I have already created a table name 'tblHolidays' and populated with 2014 Holidays. What I would like is be able to calculate (subtract or add) number of days from a date. For example subtract 2 days from 07/08/2014 and function should return 07/03/2014.
CREATE FUNCTION [dbo].[ElapsedBDays] (@Start smalldatetime, @End smalldatetime) RETURNS int AS BEGIN /* Description: Function designed to calculate the number of business days (In hours) between two dates.
I have a request where i would like to get the start date/time and end date/time and flag (with an int) which hours (24 hour clock) have values between the two dates. Example car comes into service on 2013-12-25 at 0800 and leaves 2013-12-25 at 1400 the difference is 6 hours and i need my table to show
As i'm working away at it i'm trying to figure out how i could use a Time Dimension table for this but dont really see much. So far i have the difference between the two times in hours (hour_diff) and the start hour (min_hour) so i would like to do something where i update the first hour (min_hour) and update columns based on the numbers of hours (hour_diff)
I have to produce a report to calculate no of days based on user input start date and end date.
say for eg: in the tables I have emp name user 'Phani' started work from - EStart 20/11/2014EEnd 10/01/2015 - total days --datediff within his work period he did different roles:
PhaniMarketing (prSt Date) 20/11/2014prE date (28/11/2014) Total 9 days PhaniAdmin (prSt Date) 29/11/2014prE date (20/12/2014) Total 22 days PhaniCRM (prSt Date) 20/12/2014prE date (10/01/2015) Total 22 days Total days 53 Days for this :
[code]...
HOW CAN I USE Case statement to calculate days for given start date and end date. I have to include all three totals, 1 for Job dates, 2, subjobs dates, 3 cal of days for a requested period.
I have a report that has 41 fields one of these fields is the Admit Date. I need to create a field that shows a count of Admits in the past 12 months .
I have a challenge and I'm not sure the best route to go. Consider the following dataset.
I have a table of sales. The table has fields for customer number and date of sale. There are 1 - n records for a customer. What I want is a record per customer that has the customer number and the average number of months between purchases. For example, Customer 12345 has made 5 purchases.
I am having trouble creating a sp for the following situation:
The database contains a record of the mileage of trucks in the fleet. At the end of every month, a snapshot is collected of the odometer. The data looks like this:
Hi, i'm trying to calculate the number of days between two dates, but within an UPDATE statement, so far I can't wrap my head around how I can update a field with the number of days.
I was thinking something like
Code:
Update #ClaimMaster Set covered_days = (then insert select statement that subtracts the two dates)
i have a matrix, and in that matrix i need to have one column which calculates the percentage change between a value on the current row and the same value on the previous row.
Is this possible? The RunningValue() function isn't of help as it can't help me calculate the change between two rows, and Previous() doesn't work in a matrix (why???!!!!!). Also calculating this as part of the query isn't possible as there is a single row group on the matrix, and the query is MDX.*
Thanks,
sluggy
*for those who are curious, the matrix is showing data an a per week basis, the row group is snapshot date, i am trying to measure the change in sales at each snapshot.
so I have some data that looks like this: semester weekOfSemester counts Fall 2006 4 1 Fall 2007 4 6
I want to eventually graphically represent this data over the 18 weeks of the semester in terms of Fall 2007. I need to show change weather positive or negative as a percentage against Fall 2006. Can someone help with the sql?
i am using this expression to get the time difference between two times.
{%Z.elapsed.time(@AK.VD.depart.date,@AK.VD.depart.time,@AK.VD.depart.date,@DV.VD.arrival.time,"hh.hh")*60} as [LOS (min)]
When Arrival time and depart time both are on same day above expression working to get the diference .
But if arrival date 2013-09-20 00:00:00.000 and arrival time 0800 and depart date 2013-09-21 00:00:00.000 and depart time 0050 when i calculate the time difference(using above expression) between these two i am getting -429.60 which is wrong. i have to get around 990.
I have two nvarchar fields with time data 12:34:34 and the second one 12:34 I want to calculate the difference in Hours. The first field is called (OTIM) the second field is called (ReportedTime) if the name matters. I tried substring to trim the OTIM, I am unable to make it work.
I am trying to write a query to calculate the running difference between data on different dates. Below is what my table of data looks like. Basically I want to calculate the difference between the total_completed for each state and date.
below is my code (I almost have what I need) I just can't figure out how show 0 as the completed_difference for the first Date for each state since there is no prior date to calculate against.
MRR_TOTALS_WEEK_OVER_WEEK AS ( SELECT T1.[Date] ,T1.States ,T2.Total_Completed ,ROW_NUMBER() OVER(PARTITION BY T1.States ORDER BY T1.States,T1.[Date]) AS ORDERING FROM TOTAL_CHARTS T1 LEFT JOIN TOTAL_COMPLETED T2 ON T1.[Date] = T2.[Date] AND T1.States = T2.States )
I am creating matrix report with grouping on WEEK and Fiscalyearweek,I need to calculate of difference between FY14W01,FY15W01 ande percentage of those..how to calculate in ssrs level.
I need a select statement with the condition that the date (a timestamp with format yyyy-mm-dd) is either equal to or longer than 14 months from today's date.
