I'm trying to run a dyncamic query that returns all records within a specific distance of a certain point. The longitude and latitude of each record is stored in the database. The query is constructed from two dynamic variables $StartLatitude and $StartLongitude with represent the starting point.
It runs fine until I add the 'HAVING (Distance <= 150)' clause, in which I recieve the error: Invalid column name 'Distance' It seems that Distance cannot be referenced in the HAVING clause.
I have created calcalated measures in a SQL Server 2012 SSAS multi dimensional model by creating empty measures in the cube and use scope statements to fill the calculation.
(so I can use measure security on calculations
as explained here )
SCOPE [Measures].[C];
THIS = IIF([B]=0,0,[Measures].[A]/[Measures].[B]);
Hello Friends I have 3 tables 1) Product Id, ShortName 2) IncomingStockId, ProductId, Quantity, InDate 3) OutGoingStock Id, OutDate, ProductId, Quantity I need to get the results like thisProduct name, quantity in stock today the "quantity in stock today" = sum (quantity recieved) -sum (quantity sent) Thank you for your timeSara
how do i calculate something like this if I have the table with names and count? Name Count Percent Name1 27 4.69% Name2 2 0.35% .... Totals 576 100.00%
I was trying to calculate GPA and Commulative GPA (CGPA) for this student and the formula of GPA is SUM(Honor)/SUM(CREDIT) and the formula of the CGPA is the Average of the SUM(Honor)/SUM(CREDIT) grouped by semester and I wrote the below query which is calculating the GPA correctly but wrongly calculating the CGPA.
How to get the correct CGPA shown in the below desired result set table.
select x.STUDENT_ID,AVG(x.gpa)as GPA,AVG(y.gpa)AS'COMMULATIVE GPA' from ( select STUDENT_ID,SUM(Honor)/SUM(CREDIT) gpa,ACAD_YEAR,SEMESTER
The Column bDebit has either value '0' or value '1' in it ('0' being debit - positive amount, and '1' - credit, negative amount).
I would like it to show the net amount for each account. Therefore in plain English I would like to take all GLCodes that are the same (eg 6843000701) and sum all amounts that have debit value of '0' and subtract all amounts that have debit value '1'. Therefore I would only see '6843000701' code once, and the amount would be '0' becase 600 - 600 = 0.
The current query is: SELECT dbo.tbGLTransactions.lLedgerCode, dbo.tbGLTransactions.sGLCode, dbo.tbGLTransactions.bDebit, SUM(curAmount)As TotalSum, dbo.tbLedgerCode.sGLDesc FROM dbo.tbGLTransactions INNER JOIN dbo.tbLedgerCode on dbo.tbGLTransactions.lLedgerCode = dbo.tbLedgerCode.lLedgerCode WHERE dbo.tbGLTransactions.lGLExtractRun = '452' Group By dbo.tbGLTransactions.lLedgerCode, dbo.tbGLTransactions.sGLCode, dbo.tbGLTransactions.bDebit, dbo.tbLedgerCode.sGLDesc Order By dbo.tbGLTransactions.bDebit, dbo.tbLedgerCode.sGLDesc
Is someone able to help me as to how i need to modify this query to get the desired result?
i have 3 question : 1. CAN MY MICROSOFT ACCESS Database imported to sql server 2005 ? 2. can i add field for queries with custom calculation like field 1*fiedld 2. like access can do? 3. is that any wizard to do no 1 and 2?

This is my syntax, and if I print the value that is stored in each variable @goodtries = 120 @badtries = 25 but when I run the syntax below it gives me 0.00
Declare @goodtries as int, @badtries as int select @goodtries = convert(decimal(18,4),count(userID)) from table1 WHERE logintype IN ('Valid', 'Success') select @badtries = convert(decimal(18,4),count(userID))
Hi experts,I am working on SQL server 2005 reporting services and i am getting aproblem in writting a query.Situation is given below.There is one table in database Named ChildNow i have to find the All childrens whoes Age is 13 years Base onSome given parameter.If User select Augus 2007 then It has to calculate the Childs who bornin August 1994 And if he select September Then queryshould show only those child Who born in September 1994 and soon..... And use can select another year month also likeAugust 2009 ...I am writting the following querySelect Child_Name, DOb from Childwhere ((CONVERT(DateTime, A.Date_Of_Birth, 103) >= @ Parameter1And (CONVERT(DateTime, A.Date_Of_Birth, 103) <= @Parameter2)If i know already month and year then i can write easily parameter1and parameter2 But since these are comming from user so i m notfinding how to handle this.Now please suggest me what i have to write in Where statement I thinka lot but not getting any idea about it.Any help wil be appriciated.RegardsDinesh
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
Is there a recommended practice for mirroring in regards to distance? Is it best practice to mirror with both nodes at the same physical location and use another method for failing over to a remote location or can one just put the other node in the mirror a few thousand miles away? I'm suspecting not.
Hi, please, it is possible to know the edit distance used in the fuzzy lookup/grouping. On this forum I read fuzzy lookup use 4-gram with fix size. Does exist any document explaining how fuzzy lookup calculate the similarity? In other word, what kind of edit distance, algorithm is used by fuzzy lookup/grouping? I hope I was enough clear with my poor english. Thanks All
I'm looking to find out how I'd go about setting up a database where avisitor to my site could punch in their postal code, and find out how farthey are from another postal code. For example, AutoTrader has this featureI believe to tell you how far the vehicle is from you. Dating sites havethem so you can do proximity searches.Anyone have any ideas where I could start? I'm thinking the post office,but if anyone else has suggestions, I'm open to hear them.Thanks!
Various posts have noted that mirroring over distance is not advisable or that either async connections should be used.
Are there any limits/recommendations i.e. if two datacenters are a couple of files part with 10GBs fibre links and <50ms response times would this be acceptable for high-availability mirroring?
I am new to data mining so please excuse my ignorance. Lets assume
- i have created a cluser model
- identified 3 clusters ( a, b, c)
- each record consists of 15 columns
- collecting new records( 15 variables) real time
what i would like to do is plot these new records programmatically as i collect them realtime. I assume this new record will belong to one of these three clusters. I believe we can find the cluster this new record belongs to by ' SELECT Cluster()....' and distance from the center of the cluster by ClusterDistance(). To plot this on a 2-dimentional space i need (x, y).
See here www.merriampark.com/ld.htm for information about the algorithm. This page has a link (http://www.merriampark.com/ldtsql.htm) to a T-SQL implementation by Joseph Gama: unfortunately, that function doesn't work. There is a debugged version in the also-referenced package of TSQL functions (http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=502&lngWId=5), but this still has the fundamental problem that it only works on pairs of strings up to 49 characters.

I am trying to use the haversine function to find the distance betweentwo points on a sphere, specifically two zip codes in my database. I'mneither horribly familiar with SQL syntax nor math equations :), so Iwas hoping I could get some help. Below is what I'm using and it is,as best as I can figure, the correct formula. It is not however,giving me correct results. Some are close, others don't seem right atall. Any ideas?SET @lat1 = RADIANS(@lat1)SET @log1 = RADIANS(@log1)SET @lat2 = RADIANS(@lat2)SET @log2 = RADIANS(@log2)SET @Dlat = ABS(@lat2 - @lat1)SET @Dlog = ABS(@log2 - @log1)SET @R = 3956 /*Approximate radius of earth in miles*/SET @A = SQUARE(SIN(@Dlat/2)) + COS(@lat1) * COS(@lat2) *SQUARE(SIN(@Dlog/2))SET @C = 2 * ATN2(SQRT(@A), SQRT(1 - @A))/*SET @C = 2 * ASIN(min(SQRT(@A))) Alternative calculation*/SET @distance = @R * @Cthnx,cjrsumner
I need to be able to take the latitude and logitude of two locations and compare then to determine the number of miles between each point. It doesn't need to account for elevation, but assumes a flat plane with lat and long.
Does anyone have any algorithms in T-SQL to do this?
This function computes the great circle distance in Kilometers using the Haversine formula distance calculation.
If you want it in miles, change the average radius of Earth to miles in the function.
create function dbo.F_GREAT_CIRCLE_DISTANCE ( @Latitude1 float, @Longitude1 float, @Latitude2 float, @Longitude2 float ) returns float as /* fUNCTION: F_GREAT_CIRCLE_DISTANCE
Computes the Great Circle distance in kilometers between two points on the Earth using the Haversine formula distance calculation.
Input Parameters: @Longitude1 - Longitude in degrees of point 1 @Latitude1 - Latitude in degrees of point 1 @Longitude2 - Longitude in degrees of point 2 @Latitude2 - Latitude in degrees of point 2
Hi All, Does anyone have a Stored Procedure that works perfectly to retrieve all zipcodes within a specified zipcode and distance radius - a zipcode and radius is passed and the Store Procedure result shows all zipcodes that falls within that range.
After running geography::Point(Latitude, Longitude , 4326) on the latitude and longitude provided for each location, my Geography column for each row is populated with the following:
I've got a working query which returns all leads within a supplied proximity to a city. I followed a tutorial I googled a couple months ago (can't find it now). It works, but would love others to look the query over (provided DDL and sample data) and tell me if it's as it should be.
Two things I don't like about query:
1. I have to do a UNION to another query that retrieves everything that is in the same city in order to have complete results. 2. very slow to retrieve results (> 1 minute)
