T-SQL (SS2K8) :: Nearest Neighbor Within Given Shape Query
Nov 24, 2014
I have a table with 257 mil records with latitude and longitude data.
My goal is to find the closest intersecting values from a locations table (88 rows) and update any of the 257 mil records that are applicable with the location_Name and Location_Group_Name.
The query I have works but doesn't perform well on such a big data set.
CREATE TABLE #Positions -- Base table 257 mil rows. Actual table has 20 columns
(
IDBigInt PRIMARY KEY,
LatitudeDec(10,6),
LongitudeDec(10,6),
[Code] ....
Attached you will find the tables, test data, a function to measure distance and some queries that work but are too slow for this much data.
Hi all,I am trying to show the data as the shape query, where in the left part of the table is unique and the other right fields in the grid are many in number. That is a one to many relation ship. Can I use shape query using ADO.net or Oledb please tell me how? Or else if there is any other alternative please let me know.Thanks and regards.
Hi,This is my basic sql shape query:------------------------------------------------------------SHAPE {select * from tbl1}APPEND({SELECT * FROM tbl2 where field1=1} AS RS2 RELATE field TOfield)------------------------------------------------------------With this query i get a RecordSet (RS1), who handle all the recordsfrom table tbl1, and a secondary RecordSet (RS2) who handle all therecords from table tbl2, who applies to the criteria that field1=1.It is possible that RS2 will be empty (zero records) since there is norecord in tbl2 who applies to that criteria.My wish is to design a query, that will collect only the records fromtbl1, that will have records from tbl2 who applies to the criteria -that RS2 won't be empty !I want to influence on the main part of the query (RS1), through thecriteria that is being used in the secondery query (RS2).I hope that my question is clear enough. thanks !
Hi I created a DMX query to retrieve predictions based on previous customer purchases and wanted to filter out my input data by only purchases made in the current year. I keep receiving this error:

I have a date (my birthday). I would like to find the closest birthdays to mine, both before and after my birthday. I would like to list the people in my database who are the closest age to me, but in that order. So sorting my table by age and taking a row below and above my birthday is not going to work. This is because the three people below me may all have their birthday the next day, while those above me may have theirs years before mine.
Birthdays sorted by date:
05/10/1979 jim 12/01/1980 bob 10/04/1983 mike 10/05/1983 larry 11/21/1983 dan 12/07/1984 josh 05/07/1999 dylan
The order I wish to achieve is:
10/05/1983 larry 11/21/1983 dan 12/07/1984 josh 12/01/1980 bob 05/10/1979 jim 05/07/1999 dylan
I would like to return the nearest date of Table B in my table like for
ID W001 in table B should return ID A002 CreatedDatetime: 2014-06-03 20:05:48.000 ID W002 in table B should return ID A004 CreatedDatetime: 2014-06-04 01:05:48.000
i use shape command in vb6 success but when transfer to sql query analyzer the error come out "[Microsoft][ODBC SQL Server Driver]Syntax error or access violation"
I got a problem in migrating ms access to sql server. In my vb code im using shape function and it doest work with sql server. Does sql server has shape function or are they have the same syntax? Any idea for these problem..??? Many thanks and God Blessed...
I have a derived column shape in which I replace a column with an expression.
The expression is an IF statement - a true result sets a value for the column and a false result just uses the existing value of the column (ie it replaces it with itself)
Hi,I am running SQL Server 2000 SP3 on Windows Server 2003 and since recentlyhave a strange problem executing shape queries from COM+ components usingADO.Until 4 days ago, they worked, then from one moment to the next (I must havechanged something, but I have no clue what other than restoring a 1.2 GBdatabase) they started failing with this error:Microsoft OLE DB Provider for SQL Server error '80040e14'Syntax error or access violationI have no problem executing non-shape queries, it is just the shape queriesthat fail.Any clues what may have gone wrong? Or how I can fix it?Cheers,Rsa Myh
I have an Infopath form to edit the values in the NotifyMembers table. I want to list the email addresses alphabetically when the query returns data to the form. Unfortunately, I use EmailAddressID as an int in the table, so I need to join? the NotifyMember table with the EMailAddress table, which has a column EMail which is the address. Both have EmailAddressID as common fields.
I can't get the Shape command (edit SQL in the Datasource) to be happy with any syntax that I have tried.
For (non-working) example:
select "GroupCode","EmailAddressID","DelBit" from "dbo"."NotifyMembers" as "NotifyMembers" Join "dbo"."NotifyMembers"."EmailAddressID" On "dbo"."EmailAddress"."EmailAddressID" = "dbo"."NotifyMembers"."EmailAddressID" order by "dbo"."EmailAddress"."Email"
Hi How do I get a nearest distance of a point? For example, I have two tables A and B and I want to find the nearest distance between the records of the two tables. In addition, one of the tables should also give me the distance. The data I have geo spatial data. Can this be done in SQL Help will be appreciated
Hi, I'm making a birthdays database where I want to list everyone in it ordered by the firstcoming birthdays according to the current date.
I have all the birthday records stored in a table called bursdager and the person name is stored in the navn column and the persons birthday date is stored in the dato column.
I'm having some problems, currently I have this statement:
Code:
DECLARE @tbl TABLE (navn VARCHAR(60), dato DATETIME)
INSERT INTO @tbl SELECT navn, dato FROM bursdager WHERE DATEPART(month, dato) >= DATEPART(month, getdate()) ORDER BY DATEPART(month, dato), DATEPART(day, dato)
INSERT INTO @tbl -- those are the one who allready have had birthday this year SELECT navn, dato FROM bursdager WHERE DATEPART(month, dato) < DATEPART(month, getdate()) ORDER BY DATEPART(month, dato), DATEPART(day, dato)
SELECT * FROM @tbl
It works *allmost* as it should-- except, it still lists the last persons who had birthday first, even the days after their birthday if the month is still the same.
I thought about adding an additional check: Code:
AND DATEPART(day, dato) >= DATEPART(day, getdate())
in the WHERE clause of the SELECT statement but that won't be correct either because it then just lists everyone based on whether the day number the person was born is higher or less than the day number of the current date.
Anyone have any suggestions? Is there an easier way to do it?
I have a field with seconds in it and I need to disply it in hours which I can do by dividing it by 3600, but I am trying to figure out how to round it up to the nearest 15 minutes. I have tried a couple of things with ROUND and CEILING, but am not getting the right numbers back. Any help would be greatly appreciated.
Code: AccountNo StartDateTime EndDateTime 1234 4/30/2012 8:00 AM 5/15/2012 8:00 AM
Of course there are multiple accounts, about 2100 in this case but they very by time periods, and multiple start and stop dates for an account. I need to get the start times and match them w/ the nearest end times but AFTER the value of the start time. Nearest end times must be forced to correspond to the nearest start time but there are some start times w/o end times and end times w/o start times due to user data entry errors. I need a solution that handles this. It is ok w/ the customer to make the assumption of nearest times supposedly going together so they can show the users the errors. I am on SQL Server 2008 R2.
I have the following tableCREATE TABLE Readings(ReadingTime DATETIME NOT NULL DEFAULT(GETDATE()) PRIMARY KEY,Reading int NOT NULL)INSERT INTO Readings (ReadingTime, Reading) VALUES ('20050101', 1)INSERT INTO Readings (ReadingTime, Reading) VALUES ('20050201', 12)INSERT INTO Readings (ReadingTime, Reading) VALUES ('20050301', 15)INSERT INTO Readings (ReadingTime, Reading) VALUES ('20050401', 31)INSERT INTO Readings (ReadingTime, Reading) VALUES ('20050801', 51)INSERT INTO Readings (ReadingTime, Reading) VALUES ('20051101', 106)GO-- list the tableSELECT ReadingTime, Reading FROM ReadingsGOIt is a table of readings of a free-running counter that istime-stamped.

I have such a scenario: - two tables with record containing car vehicle number, datetime of message and other data like weight ect. - first table contains only two messages for one car per one day - second has many messages for one car for one day
I would like to get a list of messages from first table but joined with the nearest (previous) record for the same car from second table.
OK, this is the scenario. I have a database with many columns ( each a mean value and a standard deviation, and with it a set of coordinates that i want to retrieve ).
Then i have a value that i want to query with the database, by comparing it with the mean and its standard deviation, and it should return a few sets (lets say 2) of coordinates whereby the the value of the mean is closet to the one in the database, in order of nearest value. How should i do it, since i am not using the exact value of the mean in the database?
I know its a bit confusing the way i wrote, but anyone understand wat i am trying to say and can help, i am very grateful. I had googled around for answers but cannot find. Thanks.
ChangeID ChangeDate EquipmentID ModuleID EquipStatus 1 12/9/08 230 1789 Normal 2 13/9/08 450 1245 Normal 3 17/9/08 230 1789 Open 4 21/9/08 230 1899 Open 5 21/9/08 450 1674 Normal 6 22/9/08 450 2364 Normal
Given a date, what module was each equipment item in on that date?How do I get the date of the nearest previous event from a list like this? I got a query from one of the post in this Forum only using Cross Apply to find the nearest record from the above table based on Date i.e.
SELECT outerT.* FROM your_table AS outerT CROSS APPLY ( SELECT TOP 1 equipment_id , change_date FROM your_table AS innerT WHERE innerT.change_date <= @point_in_time AND innerT.equipment_id = outerT.equipment_id ORDER BY change_date DESC ) AS applicable_records WHERE applicable_records.change_date = outerT.change_date
The problem is I need to get this query without using Cross Apply as i need to use the same for the LINQ which doesn't support Cross Apply.
I found in another forum that if I take the seconds and divide them by 15 then round up and multiply them by 4 I can get this done, but I can't figure out how to work it into my select statement. Anyhelp would be greatly appreciated. dbo.SLPTRANS.TimeSpent is the field I am trying to convert.
SELECT dbo.SLPTRANS.ClientID, SUM(dbo.SLPTRANS.TransValue) AS Expr1, dbo.SLPTRANS.TimeSpent AS Expr2 FROM dbo.SLPTRANS INNER JOIN dbo.INVOICE ON dbo.SLPTRANS.InvoiceID = dbo.INVOICE.RecordID GROUP BY dbo.SLPTRANS.ClientID HAVING (dbo.SLPTRANS.ClientID = 405)
Is there a way that I can do this at the table level to automatically handle the rounding of seconds, etc. down to the minute automatically without having to use a trigger?
Here is a very basic example of what I am trying to do:
--example: '09-22-2007 15:07:18.850' this is the value inserted into the table by the code select getdate()
--example: '2007-09-22 15:07:00.000' this is the value I want to store in the table select dateadd(mi, datediff(mi, 0, getdate()), 0)
I have a query which is working fine. Is it possible that if the table3's column(Child) is only related to table 1 to show it under table 1 and not under table 2, but at the same time another (Child) has a parent in table 2 (which usually is the case) it will show under table 2 as its currently doing.
In other words Child column is directly under Table2's row column name (Father), but occasionally it comes under Table1 with no relation to Table 2.
How can I out put that in a query for a treeview? I am assuming that I will have to program the out come in c# also with 3 for loops and in the second loop I can check if the column is grandchild or Child and make that as a second row or 2nd node of treeview, but I am having a problem building a query in sql.
The query below shows all Parent, then child then grand child(all well and working), but what is desired is at times child takes place of a father.
declare @x as xml set @x = ( SELECT distinct Table1.AssetSysID, Table1.Asset_ID , Table1.FromLR, Table1.Asset_ID + ', ' + Table1.[Desc2] as GarndFather, Table2.ACISysID ,Table2.PAssetSysID, Table2.FeatureName + ', ' + Table2.[DESC] AS Father, Table3.ITMSysID ,Table3.Item_ID + ',' + Table3.[DESC] as Child
SELECT right('0' + cast(month(s.closing) as varchar(2)), 2) + '/' + cast(year(s.closing) as varchar(4)) as ClosingDate, p.name as Project, SUM(s.amount) as TotalSales FROM Sales s JOIN Project p ON p.projectID = s.projectID WHEREs.closing >= DATEADD(mm, -12, GETDATE()) GROUP BY right('0' + cast(month(s.closing) as varchar(2)), 2) + '/' + cast(year(s.closing) as varchar(4)), p.name
This will give me the grouping by month/year and project.
I have the piece of sql code here below that keeps giving out duplicates. How to resolve this.
isnull((select distinct (SUM(a1.ActualDebit) - SUM(a1.ActualCredit) ) from #MainAccount a1 LEFT OUTER JOIN #BudgetAccount bb ON aa.AccountID = bb.AccountID AND a1.PeriodStartdate = bb.PeriodStartDate and a1.DateMonth=bb.DateMonth and a1.Budget = bb.Budget WHERE a1.AccountID = aa.AccountID and a1.Refdate >= @FROMDATE and a1.Refdate <= @TODATE GROUP BY a1.group1, a1.Group2),0) As Actual_CurrentMonth,
