SQL Server 2012 :: Admission Dates Overlap And Summing Of Inpatient Costs
Jun 28, 2015
I've been struggling with this for some time. we have to group data based on Patients admission date and discharge date. If any Patients discharge date + 1 = admission date then we have group both rows into one row and sum costs from both the rows. Please check out the sample input and expected output for details.
Sample Input
PatientID AdmissionDate DischargeDate Cost
1009 27-07-2014 31-07-2014 1050
1009 01-08-2014 23-08-2014 1070
1009 31-08-2014 31-08-2014 1900
1009 01-09-2014 14-09-2014 1260
1009 01-12-2014 31-12-2014 2090
1024 07-06-2014 28-06-2014 1900
1024 29-06-2014 31-07-2014 2900
1024 01-08-2014 02-08-2014 1800
Expected Output
PatientId AdminssionDate DischargeDate Cost
1009 27-07-2014 23-08-2014 2120
1009 31-08-2014 14-09-2014 3160
1009 01-12-2014 31-12-2014 2090
1024 07-06-2014 02-08-2014 6600
Please Use the below script to generate the source table and fill them up with the sample data.

We would like to benchmark our logical reads daily to show our improvement as we tune the queries over time.
I am using sys.dm_exec_query_stats summing the Physical and Logical Reads. Is this a viable option for gathering this metric? Is this a viable metric to gather?
select sum(total_physical_reads) as TotalPhyReads, sum(total_logical_reads) as TotalLogReads from sys.dm_exec_query_stats;
How best to provide performance based metrics.

Hey all,
I've got an app that's poorly designed and doesn't do connection pooling. It causes the login rate/sec on our prod server to jump up to 15/sec. I'm trying to qualify the resource cost of this behaviour. Althought this application logs in and out, it only ever has one active spid. It never holds anything in the db, it's purely an auth cost. I'm currently trying to correlate this with SQL Server cpu time, and memory.
Does anyone know where I can find some documentation, or some tips as far as login rate is concerned?
Thanks,
-Kilka

Hi All,
We're planning to install a Server 2005 Failover Cluster and I'd like to find more information about licensing, etc.
Basic questions:
- What is the best O.S. to run? Win 2003 or the new 2008? And what version (datacenter, enterprise)?
- Since I'm going to use 2 machines, will I have to pay for 2 licenses (sql and windows - two lic. each)? Or just 1 license, since just 1 machine will be the active server?
This is for some web applications, so, web environment.
Any help?
Thank you!

Is there a way to make a single insert (in a loop) and take system dates and insert them in different languages without making a new loop for each language.
Example
Create table dateLanguage(
monthName nvarchar(20),
monthNameEs nvarchar(20),
monthNameFr nvarchar(20),
MonthNamePt nvarchar(20)
)
So for example
January,
Enero,
Janvier,
janeiro

I have a dataset that contains an EmployeeID, StartDate, EndDate, and Location. Each record tells me at which location and employee was during a payroll period (fortnightly). So the data looks like:
EMP_KEYSTART_DTEND_DTLOCATION
120130117201301318103
120130117201301318103
120130131201302143354
120130131201302148103
220130117201301311234
220130131201302144567
120130214201302283354
220130214201302281234
Employees can be at multiple locations during the two weeks. They can work at one location, stop working there, start working somewhere else, and then maybe go back to their old location. There are duplicate records here as each employee can be at the same location multiple times during the two week period. What I need to capture is the actual start and end date of an employee at each location for each 'assignment'. An assignment is defined as a continual period of employment at a location with gaps of no less than 4 days - if there is a gap of more than four days then that is classed as a new assignment.

I have a customer history table with the follow structure and data:

CREATE TABLE TEMPHISTORY(
CUSTOMERID VARCHAR(11),
TIER VARCHAR(10),
STARTDATE DATE,
RECORDSTATUS TINYINT)
[Code] .....
The RECORDSTATUS value of 1 means the record is active. A corresponding record of the same CustomerID, Tier. in startdate chronology, with a value of 0 indicates that the previous record with the status of 1 has now terminated and the startdate of the record with recordstatus of 0 is the start date of the termination of the previous record, or better stated, the end date of the previous record.
What I need to do is re-record the above data the startdate of each terminated record become an enddate for the previous record, minus 1 day, as follows:
CUSTOMERID TIER STARTDATE ENDDATE
123 A 01/01/2013 02/28/2013
123 B 03/01/2013 05/31/2013

I have three tables: EMP (ID, NAME), EMPDATE (ID, STARTDATE, ENDDATE), YEAR(YEAR)
I would like to get the most recent date within a given year per each EMP? For example, EMPID 1 can be enrolled in many programs, each program has start end dates. I need to list the most recent date an employee was enrolled (max date between START AND END DATE which ever is most recent enrollment) for a given year. For example, for 2014 his/her most recent enrollment should be 10/23/2014 for year 2014 and 2013-10-24 for year 2013.

currently need to re-create an aggregate table in a proc every night to aggregate purchases broken down by person/store in groups of 3, 6 12 etc months.finding the performance of it is very slow as it covers 500,000 million rows.The query looks like
SELECTCusID(int)
, StoreID(int)
, SUM(L3M) as Last3Months
, SUM(L6M) as Last6Months
, SUM(L9M) as Last9Months
[code]...
I need to make changes to this because it is using a BETWEEN on a datetime column. I was wondering though, if anyone else has made agg tables like this before an found a better way of doing them?

What I need to be able to find is any records where the Discontinue_Date is greater than the Effective_Date on the next row for a given Customer ID and Part_ID. This is a customer pricing table so the Discontinue_Date of row 53 for example should never be greater than the Effective_Date of row 54130, these are the records I'm looking to find. So I'm looking for a SELECT query that would look for any records where this is true. Obviously the last Discontinue_Date row for a Customer_ID will not have a next row so I wouldn't want to return that.

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 table full of service invoice records. Some of the invoices are continuous, meaning that there may be an invoice from 01-16-2015 through the end of that month, but then another invoice that starts on feb 1 and goes for 6 months.
I want to only pull the most recent. Keep in mind that there may be other invoices in the same table for a different period. An example might be:
FromDate ToDate Customer Number Contract Number
02/01/2015 07/31/2015 2555 456
01/15/2015 01/31/2015 2555 456
04/01/2013 09/30/2015 2555 123
03/13/2013 03/31/2013 2555 123
From this table, I would like a query that would give me this result:
01/15/2015 07/31/2015 2555 456
03/13/2013 09/30/2015 2555 123
There will likely be more than just 2 consecutive records per contract number.

Both DateOfArrival and DateOfDeparture are in the same table (let's say GuestStay).

Hi
Say I've got two time intervals represented two rows of Start Date and End Date.
Can anyone think of a way to express a query in which I can work out how many days the time intervals overlap each otheR?
Like for example if the first interval is pretty 1/5/08 and 13/5/08
and the second one is 5/5/08 and 15/5/08, then i guess the answer should be 8 days.

Hi All,I'm a relative newbie to SQL Server, so please forgive me if this is adaft question...When I set "Show Execution Plan" on in Query Analyzer, and execute a(fairly complex) sproc, I note that a particular query is reported ashaving a query cost of "71% relative to the batch" - however, this isnowhere near the slowest executing query in the batch - other querieswhich take over twice as long are reported as having costs in theorder of a few percent each.Am I misreading the execution plan? Note that I'm looking at thegraphical plan, and am not reading the 'estimated' plan - I'm usingthe one generated from executing the sproc. My expectation was thatthis would be based on the execution times of the queries within thesproc, however, this does not appear to be the case. (Note - Idetermined execution times from PRINT statements, using GETDATE() todetermine the current time, down to milliseconds).Any feedback would be of great assistance... I may well have tochange the way I approach optimizing queries based on these findings.Thanks,LemonSmasher.

There has been a number of topics recently regarding calculations of overlapping times. Here is one approach to reach this with a UDF.CREATE FUNCTION dbo.fnTimeOverlap
(
@FromTime DATETIME,
@ToTime DATETIME,
@Login DATETIME,
@Logout DATETIME
)
RETURNS INT
AS
BEGIN
DECLARE@Temp DATETIME,
@Seconds INT
IF @FromTime > @ToTime
SELECT@Temp = @FromTime,
@FromTime = @ToTime,
@ToTime = @Temp
IF @Login > @Logout
SELECT@Temp = @Login,
@Login = @Logout,
@Logout = @Temp
SELECT@Seconds = CASE
WHEN @FromTime <= @Login AND @Login <= @ToTime AND @ToTime <= @Logout THEN DATEDIFF(second, @Login, @ToTime)
WHEN @FromTime <= @Login AND @Logout <= @ToTime THEN DATEDIFF(second, @Login, @Logout)
WHEN @Login <= @FromTime AND @ToTime <= @Logout THEN DATEDIFF(second, @FromTime, @ToTime)
WHEN @Login <= @FromTime AND @FromTime <= @Logout AND @Logout <= @ToTime THEN DATEDIFF(second, @FromTime, @Logout)
END
RETURN@Seconds

I have a temporary table (@tblResults) that has 4 columns that need to be populated with a calculation made from columns held within 2 other tables.
Joins
@tblResults tr JOIN dbo.MarketPrice mp
ON tr.Item = mp.Item
AND tr.[Month] = mp.[Month]
AND tr.[Year] = mp.[Year]
AND mp.[Date] BETWEEN tr.LatestStartDate AND tr.PriorEndDate
[code]....
Where the 2 dbo.MarketPrice and dbo.MillDifferentials date fields are NOT equal, the last (chronologically) dbo.MillDifferentials.Diff value should be used (or '0' if no previous value found).
so expected results where @tblResults.Id = 1:
The dbo.MarketPrice.Price value of '2014-10-29' should be combined with the dbo.MillDifferentials.Diff value of '2014-10-06' - this produces the combined Max value of 184.50
The dbo.MarketPrice.Price value of '2014-04-28' should be combined with the dbo.MillDifferentials.Diff value of '2014-04-28'
The dbo.MarketPrice.Price value of '2014-01-22' should be combined with the dbo.MillDifferentials.Diff value of '2014-01-20'
The dbo.MarketPrice.Price value of '2014-01-21' should be combined with the dbo.MillDifferentials.Diff value of '2014-01-20' - this produces the combined Min value of 111.50
The dbo.MarketPrice.Price value of '2014-01-04' should be combined with '0.00' if there is no matching or previous dbo.MillDifferentials.Diff value OR the top 1/max (most recent) dbo.MillDifferentials.Diff value if a record is found before the specified @tblResults.LatestStartDate

I am writing report to display some IIS site activity, part of the requirement is to produce a trend for user activity for each week of the year.
I have written a stored procedure that uses datepart to split year, month and year week number into separate columns. However the problem I am having is that when a week is split over 2 months I end up with the two entries for the same week but across two months which also splits the count of activity into two rows. So when I produce a line chart in SSRS I end up with a dip due to the week total being split.
An example would be week number 14 of this year is split over two months, I think I need to add same week number activity counts together but not sure how to handle this in the stored procedure.

Just want to check if my query is the standard way to check if date ranges overlap in a price table as I need to check any that overlap as I can't have two prices on one day.
For example if in a table there was:
Product TROUSER Colour BLUE
Start Date 01-NOV-13 End Date 20-NOV-13 Price £20.00
Start Date 10-NOV-13 End Date 12-NOV-13 Price £18.00
Start Date 21-NOV-13 End Date 25-NOV-13 Price £15.00
The top two overlap.I'm doing this which is giving me nothing returned which I'm hoping means I have no overlapping date ranges:
SELECT a.[PriceList]
,a.[ProductID]
,a.[Colour]
,a.[Start Date]
,a.[End Date]
,a.[Product Price]

I'm building a proc to generate fake stock portfolios for testing. I have a list of thousands of symbols, and I want the tester to be able to select how many symbols they want in their fake portfolio, and then give each symbol a random weighting (i.e. percentage held in that security) which, across all the symbols, sums to 100%. The securities here are not the part I care about, it's the weightings summing to 100 that's important.
So test data would look something like this:
/*
--This is the repository of potential symbols I can add to a fake portfolio.
-- So the simple part is basically select top (@symbolCt) from #PossibleSymbols, plus some magic I have yet to determine
if object_id('tempdb.dbo.#PossibleSymbols') is not null drop table #PossibleSymbols
create table #PossibleSymbols
(
SymbolID int
)
insert into #PossibleSymbols (SymbolID)

I am designing a database to store data from a leak tester.
We want to display the results between dates, I mean, the results of the leaking test are going to be stored as well as the datetime in which they have been performed.
ID (int)
RESULT (float)
TS (datetime)
The query will be, of course:
SELECT * FROM TABLE Where TS BETWEEN DT1 and DT2
This table is growing by 10000 rows a day, it is possible that in a year getting the values between two dates became impossible.
Using a index with a datetime field sounds like a crazy idea.

I've just restored a DB from one server to another. Part of the DB is an assembly used in a Function that unencrypts some data held in a Varbinary(Max) column.
When I execute it on the original server it works fine across all rows of the table, when I execute it against the new server it fails because it's seeing dates in MM/DD/YYYY format, it works if the day of the month is less than 13, but obviously the date would be wrong!
Setting the DATEFORMAT to MDY prior to executing the function has no effect either.
It's the same DLL in the same location, the SQL Server settings as returned by DBCC USEROPTIONS() are identical.
The SQL Server editions and Window OS are the same

To set the scene I am using SQL 2012, in project deployment mode (SSIS Catalog rather than file system).I have setup an SSIS package to run a stored procedure which exports data for the last hour to a .tsv file and then FTP's the file to some other location via a sql agent job - This all works fine.However, I can see there may be a requirement to run the package with dates that need to be set i.e. in the event of a lost file of some other reason the package has not run and missed some of its hourly slots and the customer requires the files to be resent.
The stored procedure I am using has parameters for "DateOverride" - boolean), "start" and "end" dates (datetime) with defaults set "0" for "DateOverride" and null for the "Start" and "End" dates, I have built logic into the procedure which sets the dates if the parameters are null (as in the above to an hour before now). What I would like to be able to do (and this is to make it user friendly for support staff) is to be able to set parameters/variables in SQL agent with "DateOverride" set to "1" and the the dates I would like to be sent to the stored procedure "Start" and "End" parameters.
I did try using the parameters in SSIS which worked well when the values were true or false (0,1) but didn't work at all for the dates. If I left the dates as I had set them is SSIS it worked, but if I changed them (even if it was just changing the hour) the job errored/crashed and corrupted the job step leaving me the ability to only delete it.
