I have a SSRS Report that displays the total number of days lapsed since a complaint was received. This SQL Query is the difference between today's date and date of the last received complaint.
SELECT DATEDIFF(day, MAX(complaints.ComplaintReceived1Date),CURRENT_TIMESTAMP) as total
FROM complaints WITH (nolock)
If for example this is set to 30 (days) and then a complaint is received in my SSRS report I would like to display 30 as previous number of days with no complaint record. Is there a way to store previous results and recall this data? Maybe a temp table?
You are already storing it in the table referenced by your SQL query.
I would just retrieve it from there:
; with previouscomplaint as (
select
complaintreceived1date,
RN = ROW_NUMBER() over (partition by complaintreceived1dateorder by complaintreceived1date desc))
select datediff(day,complaintreceived1date,current_timestamp) as previoustotal from previouscomplaint where RN=2
If you want the dates between the two rows, make the second statement:
select datediff(day, (select complaintreceived1date from previouscomplaint where rn = 2),(select complaintreceived1date from previouscomplaint where rn = 1)) as previoustotal
This was not tested, but should work.

Good morning,
I have a problem I've been trying to solve for but am getting now where.
I need to find the max date of the previous month. Normally I would just use the following to find the last day of the previous month: last_day(add_months(current_date, -1)
However, this particular data set doesn't always have the last day with data. E.g. Last day in the data for May was May 30th. Obviously if i try using the syntax above it would return no data because it would be looking for 5/31.
So is there a way to find the "max" day available in the data of the previous month? Or the month prior etc.?
For example like this (two scans of table: one in subquery to find max date and one in main query):
select *
from mytable
where as_of_date in (select max(as_of_date) from mytable where as_of_date between first_day(add_months(current_date, -1)) and last_day(add_months(current_date, -1))
Or (single scan + analytic function) like this
select col1 ... colN
from
(
select t.*, rank() over (partition by month (t.as_of_date) order by t.as_of_date desc) rnk
from mytable t
where --If you have partition on date, this WHERE may improve performance
t.as_of_date between first_day(add_months(current_date, -1)) and last_day(add_months(current_date, -1))
)s
where rnk=1
I am trying to figure out the aggregate functions in SQL SSRS to give me to sum of total sales for the given information by YEAR. I need to combine the year, the months within that year and provide the total sum of sales for that year. For example: for 2018 I need to combine month's 2-12 and provide the total sum, for 2019 combine 1-12 and provide total sum and so on.
enter image description here
I'm not sure where to begin on this one as I am new to SQL SSRS. Any help would be appreciated!
UPDATE:
Ideally I want this to be the end result:
id Year Price
102140 2019 ($XXXXX.XX)
102140 2018 ($XXXXX.XX)
102140 2017 ($XXXXX.XX)
And so on.
your query:
Select customer_id
, year_ordered
--, month_ordered
--, extended_price
--, SUM(extended_price) OVER (PARTITION BY year_ordered) AS year_total
, SUM(extended_price) AS year_total
From customer_order_history
Where customer_id = '101646'
Group By
customer_id
, year_ordered
, extended_price
--, month_ordered
Provides this:
enter image description here
multiple "years_ordered" because it is still using each month and that months SUM of price.
There are two approaches.
Do this in your dataset query:
SELECT Customer_id, year_ordered, SUM(extended_price) AS Price
FROM myTable
GROUP BY Customer_id, year_ordered
This option is best when you will never need the month values themselves in the report (i.e. you don't intend to have a drill down to the month data)
Do this in SSRS
By default you will get a RowGroup called "Details" (look under the main design area and you will row groups and column groups).
You can right-click this and add grouping for both customer_id and year_ordered. You can then change the extended_price textbox's value property to =SUM(Fields!extended_price.Value)
You could use a window function in your SQL:
select [year], [month], [price], SUM(PRICE) OVER (PARTITION BY year) as yearTotal
from myTable
I have a calendar table called CalendarInformation that gives me a list of dates from 2015 to 2025. This table has a column called BusinessDay that shows what dates are weekends or holidays. I have another table called OpenProblemtimeDiffTable with a column called number for my problem number and a date for when the problem was opened called ProblemNew and another date for the current column called Now. What I want to do is for each problem number grab its date ranges and find the dates between and then sum them up to give me the number of business days. Then I want to insert these values in another table with the problem number associated with the business day.
Thanks in advance and I hope I was clear.
TRUNCATE TABLE ProblemsMoreThan7BusinessDays
DECLARE #date AS date
DECLARE #businessday AS INT
DECLARE #Startdate as DATE, #EndDate as DATE
DECLARE CONTACT_CURSOR CURSOR FOR
SELECT date, businessday
FROM CalendarInformation
OPEN contact_cursor
FETCH NEXT FROM Contact_cursor INTO #date, #businessday
WHILE (##FETCH_STATUS=0)
BEGIN
SELECT #enddate= now FROM OpenProblemtimeDiffTable
SELECT #Startdate= problemnew FROM OpenProblemtimeDiffTable
SET #Date=#Startdate
PRINT #enddate
PRINT #startdate
SELECT #businessday= SUM (businessday) FROM CalendarInformation WHERE date > #startdate AND date <= #Enddate
INSERT INTO ProblemsMoreThan7BusinessDays (businessdays, number)
SELECT #businessday, number
FROM OpenProblemtimeDiffTable
FETCH NEXT FROM CONTACT_CURSOR INTO #date, #businessday
END
CLOSE CONTACT_CURSOR
DEALLOCATE CONTACT_CURSOR
I tried this code using a cursor and I'm close, but I cannot get the date ranges to change for each row.
So if I have a problemnumber with date ranges between 02-07-2018 and 05-20-2019, I would want in my new table the sum of business days from the calendar along with the problem number. So my output would be column number PROB0421 businessdays (with the correct sum). Then the next problem PRB0422 with date ranges of 11-6-18 to 5-20-19. So my output would be PROB0422 with the correct sum of business days.
Rather than doing this in with a cursor, you should approach this in a set based manner. That you already have a calendar table makes this a lot easier. The basic approach is to select from your data table and join into your calendar table to return all the rows in the calendar table that sit within your date range. From here you can then aggregate as you require.
This would look something like the below, though apply it to your situation and adjust as required:
select p.ProblemNow
,p.Now
,sum(c.BusinessDay) as BusinessDays
from dbo.Problems as p
join dbo.calendar as c
on c.CalendarDate between p.ProblemNow and p.Now
and c.BusinessDay = 1
group by p.ProblemNow
,p.Now
I think you can do this without a cursor. Should only require a single insert..select statement.
I assume your "businessday" column is just a bit or flag-type field that is 1 if the date is a business day and 0 if not? If so, this should work (or something close to it if I'm not understanding your environment properly).:
insert ProblemsMoreThan7BusinessDays
(
businessdays
, number
)
select
number
, sum( businessday ) -- or count(*)
from OpenProblemtimeDiffTable op
inner join CalendarInformation ci on op.problem_new >= ci.[date]
and op.[now] <= ci.[date]
and ci.businessday = 1
group by
problem_number
I usually try to avoid the use of cursors and working with data in a procedural manner, especially if I can handle the task as above. Dont think of the data as 1000's of individual rows, but think of the data as only two sets of data. How do they relate?
To make the example super simple, lets say that I have a table with three rows, ID, Name, and Date. I need to find the count of all ID's belonging to a specific name where the ID does not belong to this month.
Using that example, I would want this output:
In other words, I want to count how many ID's that a name has that aren't this month/year.
I'm more into PowerShell and still fairly new to SQL. I tried doing a case statement, but because it's not a foreach it seems to be returning "If the Name has ANY date in this month, return NULL" which is not what I want. I want it to count how many ID's per name do not appear in this month.
SELECT NAME,
CASE
WHEN ( Month(date) NOT LIKE Month(Getdate())
AND Year(date) NOT LIKE Year(Getdate()) ) THEN Count(id)
END AS TotalCount
FROM dbo.table
GROUP BY NAME,
date
I really hope this makes sense, but if it doesn't please let me know and I can try to clarify more. I tried researching cursors, but I'm having a hard time grasping them to get them into my statement. Any help would be greatly appreciated!
You only want to group by the non-aggregated columns that are in the result set (in this case, Name). You totally don't need a cursor for this, it's a fairly straight-forward query.
select
Name,
Count(*) count
from
tbl
where
tbl.date > eomonth(getdate()) or
tbl.date <= eomonth(dateadd(mm, -1, getdate())
group by
Name
I did a little bit of trickery on the exclusion of rows that are in the current month. Generally, you want to avoid running functions on the columns you're comparing to if you can so that SQL Server can use an index to speed up its search. I assumed that the ID column is unique, if it's not, change count(*) to count(distinct ID).
Alternative where clause if you're using older versions of sql server. If the table is small enough, you can just do it directly (similar to what you tried originally, it just goes in the query where clause and not embedded in a case)
where
Month(date) <> Month(Getdate())
AND Year(date) <> Year(Getdate())
If you have a large table and sarging on the index is important, there some fun stuff you can build eomonth with dateadd and the date part functions, but it's a pain.
SELECT Name, COUNT(ID) AS TotalCount
FROM dbo.[table]
WHERE DATEPART(MONTH, [Date]) != DATEPART(MONTH, GETDATE()) OR DATEPART(YEAR, [Date]) != DATEPART(YEAR, GETDATE())
GROUP BY Name;
In T-SQL:
SELECT
NAME,
COUNT(id)
FROM dbo.table
WHERE MONTH(Date_M) <> MONTH(GETDATE())
GROUP BY NAME
I have a table for Inventory Dollars by Vendor by Month. I want to be able to update the dollar amounts for the current month on a daily basis, but I don't want to lose the previous month's data. Here is the basic query I have:
DELETE Inventory_Dollars
FROM Inventory_Summary
WHERE MonthNum = '4'
SELECT
SUM(Cost*OnHand) AS Inventory_Dollars
FROM Inventory
The Inventory table will always hold the current data. How can I just Insert Into Inventory_Summary the data from the Select statement?
Just preface your query with an INSERT:
INSERT INTO Inventory_Summary
(Inventory_Dollars)
SELECT SUM(Cost * OnHand) AS Inventory_Dollars
FROM Inventory
If you've already inserted the inventory_dollars amount for the current month, you can then update the value every day with something like this:
UPDATE Inventory_Summary
SET Inventory_Dollars = (
SELECT (Cost * OnHand)
FROM Inventory
)
WHERE MonthNum = DATEPART(m, GETDATE()) AND Year = DATEPART(year, GETDATE())
The DATEPART can be used to fill in the number of the month for the current date, GETDATE(). Then you won't be updating the inventory_dollars values for past months.
Edit: Also added a year to the where clause, so you don't update months from past years.
Edit 2: If you use a subquery in the SET, make sure only one result can come back.
