Transact SQL :: Query To Identify Overlapping Date Rows
Aug 18, 2015
I have a table with multiple rows per staff person. Each of these rows has staff_id, start_date, and end_date. Per staff, if any start_date comes between the start_date and end_date of a different row, or if any end_date comes between the start_date and end_date of a different row, then I have to flag these records as being identical.
How can I do this? I have tried doing a Cross Apply because I thought that would do Cartesian product (comparing every row), and I've also tried temp tables. But I haven't gotten either of these to work. Here is some dummy data:
if exists (select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#staff_records')
) DROP TABLE #staff_records;
create table #staff_records
(
staff_id varchar(max),
And I would like to produce the following outcome to the same table (using update statement): As what you all observe, it merge all overlapping dates based on same promotion ID by taking the minimum start date and maximum end date. Only the first row of overlapping date is updated to the desired value and the flag value change to 1. For other overlapping value, it will be set to NULL and the flag becomes 2.
The second part that I would like to acheive is based on the first table as well. However, this time I would like to merge the date which results in the minimum start date and End Date of the last overlapping rows. Since the End date of the last overlapping rows of promotion ID 1 is row with ID 4 with End Date 2015-05-29, the table will result as follow after update.
IF OBJECT_ID('tempdb..#OverLappingDates') IS NOT NULL DROP TABLE #OverLappingDates CREATE TABLE #OverLappingDates ( MemberID Varchar (50), ClaimID Varchar(50), StartDate DateTime, EndDate DateTime )
[Code] ....
I need to select only records where dates are over lapping for the same memberid...For this scenario i need an output First 2 records (MemberID 1 has 2 claiims overlapping dates).
So my data column [EODPosting].[MatchDate] is defined as a DATE column. I am trying to SELECT from my table where [EODPosting].[MatchDate] is today's date.
Is this not working because GETDATE() is like a timestamp format? How can I get this to work to return those rows where [EODPosting].[MatchDate] is equal to today's date?
So What I am trying to accomplish is sum up overlapping time ranges while also keeping Unique data rows within the table. So If a data row is unique meaning it is NOT within a overlapping group of data rows then I want to just insert it into a "final table", but if the data rows are overlapping then I want to grab the min(timestart) and the max(timestop) and the PKID of the data row with the max(timestop) within the overlapping group.
I accomplish this task using nested cursors, however When I place my method into a trigger which runs on INSERT, then my trigger never runs and nothing happens. Is there a way to accomplish this without using cursors. I have placed my cursor method into the sql fiddle to be inspected.
create table temp1 ( pkid int, line int, dateentry date, timestart time, timestop time )

I am trying to create a check constraint that prevents entry of a date range that overlaps any other date range in the table. The below example script results in the error message: The INSERT statement conflicted with the CHECK constraint "ck_dt_overlap". what I am doing wrong?
CREATE TABLE t1 (d1 date,d2 date) go create function dbo.dt_overlap (@d1 date, @d2 date) RETURNS BIT AS BEGIN IF EXISTS (SELECT 1 from t1 where d1 between @d1 and @d2 or d2 between @d1 and @d2) RETURN 1 RETURN 0 END go alter table t1 add constraint ck_dt_overlap CHECK (dbo.dt_overlap(d1,d2)=0) go insert into t1 values ('2015-01-01','2015-02-01') insert into t1 values ('2015-01-15','2015-02-15')
--BOTH inserts result in the following message: The INSERT statement conflicted with the CHECK constraint "ck_dt_overlap".
I've gone cold here. Dunno if I've had too little coffee - as I'm currently drinking some seriously wicked green tea - or whether my brain has locked down from yesterdays "bad eggs for lunch" experience.
Anyway... I have database with a customer, for each customer is a related history table with assigned consultant.
The assigned consultant table has information on consultant id, name, the start date of his assignment and the end date.
I need to find all customers that currently have (or have had) two or more consultants actively assigned. In other words, I need to see if the start/end times overlap.
At my current state, I'm just done.. i can't maintain the perspective... how do I do this?
Question: How to determine if a date value was between one of the date periods that appear in multiple rows?
Background: We have a table of "license valid" periods, wherein each license can have one or more rows. (As you know, a driver's license can be started, expired, renewed, suspended, reinstated, revoked, etc.) Instead of of having a license activity table--from which valid license periods could be extrapolated--we store just the periods for which a license was valid.
My task is to take a list of licenses and specific dates and determine if each license was valid as of that date, returning either true or false. What is the best way to accomplish this?
DECLARE @ValidityInQuestion TABLE ( LicenseID int , DateValidityInQuestion date);
DECLARE @LicenseValidPeriods TABLE ( LicenseID int , BeginDate date , EndDate date);
[Code] ...
How then do I query both tables in order to get the same result that results from the following query?
SELECT 12345 AS LicenseID , '2015-01-15' AS DateValidityInQuestion , 1 AS LicenseActive UNION SELECT 67890 , '2015-02-04' , 0;
I assume I need to join on the LicenseID columns, but my understanding stops there.
how to write a query to get current date or end of month date if we pass year and month as input
Eg: if today date is 2015-09-29 if we pass year =2015 and month=09 then we have to get 2015-09-29 if we pass year =2015 and month=08 then we have to get 2015-08-31(for previous months we have to get EOMonth date & for current month we have to get current date).
I'm new to sql. Can someone help me to write a script to select overlapping start dates for each client records. For example: Clientid 1 have 3 episode as below(I only want to see the first two records with overlapping start date records)
I need to identify time spans where members identified as having a condition have NOT had any of 5 specified services in the past 12 months. I have a table (DiabStrata) that identifies time frames for which my data shows a member as having the condition, and I have 5 separate tables with the dates of the relevant services.
I can easily identify when a member hasn't had the service at all, or is lacking it at the start or end of the time frame for which they have the condition, but I'm hitting a wall on how to deal with gaps between the minimum and maximum identification dates.
insert DiabStrata( select '1',1,'20060101','20070302' union select '1',1,'20070803','20080804' union select '2',1,'20020101','20080503')
insert hba1c(
select '1','20060301'
union
select '1','20070301'
union
select '2','20050101')
--Missed Service Begin select * into #eval from DiabStrata where strat=1
delete #eval from #eval left join hba1c on #eval.memberid=hba1c.memberid where hba1c.memberid is null --repeat for other indicators
update e set stratstart=min(dos) from #eval e join hba1c on e.memberid=hba1c.memberid having min(dos)>stratstart
update e set stratend=max(dos)+365 from #eval e join hba1c on e.memberid=hba1c.memberid having max(dos)+365<stratend
delete from #eval where stratstart>stratend --repeat for other indicators Desired output is into DiabStrata with a strat of 2 for the time frame for which they have strat 1 but do not have all 5 services within the prior 365 days. MID Strat StartStrat EndStrat 1 2 1/1/06 - 2/28/06 1 2 3/2/08 - 8/4/08 2 2 1/1/02 - 12/31/04 2 2 1/2/06 - 5/3/08
A vehicle loading confirm after that what time its gated out so i want to take the time duration between finish loading and gate out, find sample table records , i want to take more than 5 hrs difference between finish loading and gate out.
Imagine I set a begin transaction on table a and updating a row and not committed and not roll backed--first connection
From second connection I am selecting same table (obviously it wait until first connection commits/rollback based on my transaction level: my isolation level is read committed).
1. How do I know second connection is to waiting to first connection to complete. 2. If I want to select rows that are not locked by update process how do i need to do(ex:row 1,2,3,4 and 1 is locked by update process(exclusive lock) and i want to leave that and i need to select 2,3,4 records).

I need to identify which shift is currently running on by providing the current time.I used the following query to get the result. It is giving correct result for Morning & Afternoon Shift but failed to produce result for Night Shift.
SELECT ShiftName, Shiftid FROM WHShifts WHERE DATEPART(HOUR, @Currenttime)>=(DATEPART(HOUR,CAST(ShiftInTime AS Datetime))) AND DATEPART(HOUR, @Currenttime)<=(DATEPART(HOUR,CAST(ShiftOutTime AS Datetime)))
Is there any way to find out the night shift from a given time.
Please refer to the below query. I want to filter inner join rows based on outer query column value (refer to bold text).
SELECT M.MouldId, SI.StockCode, MI.Cavity, MI.ShotCounter, CQ.SumOfCastedQty as CastedQty, MI.CounterStartup FROM MouldItem MI JOIN (SELECT JD.MouldId, JC.StockCode, SUM(JS.CastedQty) AS SumOfCastedQty FROM JobCasting AS JS INNER JOIN JobCreationDet AS JD ON JS.JobDetId = JD.Uniid INNER JOIN JobCreation AS JC ON JD.JobIdx = JC.Uniid
I have persons who speaks multiple languages and they are in one table, each row is added if he/she speaks multiple languages. Instead I want to add additional columns and load the data.(what I have shown in the desired output)
name language ------------- ron english ron french ron spanish andy english andy hindi kate english
Desired output
name language1 language2 language3 language4 language5 language6 ----------------------------------------------------------------- ron english french spanish andy english hindi Kate english
ColA ColB ----- ----- 21 A 22 A 23 A 24 B 25 B 26 D
What I want is to be able to identify a set sequence (1,2,3) based upon ColB such that I'd get the following result:
ColA ColB ColC ----- ----- ----- 21 A 1 22 A 1 23 A 1 24 B 2 25 B 2 26 D 3
I know that I should be able to get it using ROW_NUMBER() OVER (PARTITION BY ColB ORDER BY ColA), but instead of getting the sequence (1,1,1,2,2,3) I get (1,2,3,1,2,1). Using DENSE_RANK gave me the same results.
I've attempted to identify a primary and foreign key in these two tables, but I am getting a bunch of errors re duplicate keys and column names needing to be unique.Perhaps the primary and foreign key I have identified don't meet the criteria?
CREATE TABLE StockNames ( -- Added Primary key to [stock_symbol] [stock_symbol] VARCHAR(5) NOT NULL CONSTRAINT PK_stock_symbol PRIMARY KEY, [stock_name] VARCHAR(150) NOT NULL, [stock_exchange] VARCHAR(50) NOT NULL,
I have two columns, one column has a document ID and a given document can have many pages. The second column has the pages. Now I want to find out when the page number is broken. For example, if doc ID 1 has 3 rows and each of the three has 1,2,3 and then the fourth row has document 1 but the value jumps from 3 to 7 and then goes to 8,9,10 and then jumps again and starts from 17, i want to have the ranges identified.
I have three tables, Accounts, AccountCustomer and Customers, and the data-relationshiop between are defined according to the image below:
I created also a query (the sql-query below), displaying the customers for every account that is on the table "Accounts", and I got the results, as we can see in the image below:
SELECT A.AccountID, c.CustomerNo, c.Surname, c.Name, c.TaxNum FROM Accounts A left join AccountCustomer ac on ac.AccountID = A.AccountID left join Customers c on c.CustomerNo = ac.CustomerNo order by A.AccountID;
As we understand, an "AccountID" have multiple customers, so I want to transform tha multiple results to one row, grouping by AccountID (one account belongs to one or many Customers), like the image below:
I tried to use row_number()-expression to get this, but I didn't make it. So my question is, how can I alter my sql-query to get the final result like image above?
I hate to ask such silly helps..but I'm missing something here..need help. I have a table having columns for createddate and deleteddate. The data gets created and deleted periodically and I need to find out the number of created,deleted and remaining number of records on each day. This query works, but takes a lot of time...not sure if there is a more better way to do this.. Please help SELECT CAST(createddate AS DATETIME) AS createdDate, Created, Deleted, Remaining FROM( SELECT CONVERT(VARCHAR,createdon,102) AS CreatedDate, COUNT(1) created, (SELECT COUNT(1) FROM table ta2 WHERE CONVERT(VARCHAR,ta2.deletedon,102) = CONVERT(VARCHAR,ta.createdon,102)) Deleted, ((SELECT COUNT(1) FROM table ta1 WHERE CONVERT(VARCHAR,ta1.createdon,102) <= CONVERT(VARCHAR,ta.createdon,102)) - (SELECT COUNT(1) FROM table ta1 WHERE CONVERT(VARCHAR,ta1.deletedon,102) <= CONVERT(VARCHAR,ta.createdon,102))) Remaining FROM table ta WHERE CONVERT(VARCHAR,createdon,102) >= (GETDATE() - 90) GROUP BY CONVERT(VARCHAR,createdon,102) ORDER BY CONVERT(VARCHAR,createdon,102) DESC) AS tmp
I have the follwing function in my SQL data base which is hosted in Azure.
All date and time field in my db are store as UTC and I have a function define as below :
ALTER FUNCTION [dbo].[func_GetCurrentLocalTimeFromUTC] ( ) RETURNS datetime AS BEGIN DECLARE @OffSet as int = 1 DECLARE @CurrentDate as datetime = getUTCdate()
[Code] ...
Now what I have trying to do is to perform a select statement on a table where I have a dateTime value field and add the proper offset value to the field in order it is display based on where user will run the query. For example if I run this simple query :
SELECT INVENTORYDATE from Inventory
Will return the UTC dateTime value.
How can I use the select statement in order to get the field format with proper offset based on user pc timezone/. Please note that the query will be called from a rrs.
This one is making my head hurt! Trying to figure out how to query for records between date range. The records have a start_date and an end_date field. The end_date field maybe null.
For example, say you wanted to see the records of everyone checked into a hotel during a given date range. You need to account for the people that checked in before you @start_date parameter and may check out after your @end_date parameter.
fyi- As for the null end_date field, think of this as they have checked in and not sure when they will checkout yet.
