T-SQL (SS2K8) :: Returning Rows Within Certain Distance In Miles From City Using Longitude And Latitude

Nov 19, 2014

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)

Sample DDL: 2 tables
create table dim_lead
date_created datetime,
[contact_first_name] varchar(20),
[contact_last_name] varchar(20),
lead_id int,

[Code] .....

SQL 2012 :: Calculate (Number Of Days To Pay) Logic

Jun 24, 2014

How to write a query that calculate the number of days (approx) that it takes to a customer to pay an invoice.

Document Types

1 Payment
2 Invoice
3 Credit Memo
4 Finance Charge Memo
5 Reminder
6 Refund

There are three methods to consider when calculating the days to pay logic.

Method 1 - Simple : Look for Document Type 2 (Invoice), if "closed at date" > "posting date" then number of days = ("closed at date" - "posting date")

Method 2 - A Document Type 1 (payment) closes a Document Type 2 (Invoice)
For this method the formula would be: Payment Record (1) "posting date" - Invoice Record (2) "posting date"

Method 3 - An Invoice closes the payment.

On a payment entry “closed by entry no.” refers to an Invoice entry.

a. In our code we are not on the payment looking for the invoice, we are on the invoice.
i. Because of this we need to find the entry that our current invoiced has closed.

I am taking this from a page that has the pascal code that I need to translate to SQL.

IF (CustLedgEntry2."Document Type" = CustLedgEntry2."Document Type"::Invoice) AND
NOT CustLedgEntry2.Open
IF CustLedgEntry2."Closed at Date" > CustLedgEntry2."Posting Date" THEN
UpdateDaysToPay(CustLedgEntry2."Closed at Date" - CustLedgEntry2."Posting Date")

[Code] ....

I am also including create table and insert data scripts ...

SQL Server 2012 :: Calculate Customers Age And Value By Month And Year?

Sep 22, 2014

What's the best way to calculate a customers age and value by month and year?

I need to be able to calculate customer value by month and year, and then to calculate their age at each month in time. I've found a way of grouping sales by month and year that includes age for a particular contact like this:

select fh.contact_number
, concat(year(fh.transaction_date), '-', month(fh.transaction_date)) as transaction_month_year
, cast(fh.transaction_date as date) as transaction_date
, sum(fh.amount) as ttl_amount_in_month

[Code] .....

It seems to work, but any better way to achieve this?

SQL 2012 :: Calculate Time Difference For Consecutive Rows?

Jul 2, 2015

I have a table like this.

([S_ID] varchar(7), [S_ACTV_CODE] varchar(4), [S_USER] varchar(5), [S_DATETIME] varchar(19), [S_ACT_IND] int)
('AAA-111', NULL, 'USER1', '2015-06-15 00:21:06', 0),
('AAA-111', '2', 'USER1', '2015-06-15 00:21:07', 0),


Basically I want to calculate the time spent by S_Users on a particular S_ACTV_CODE:

- S_ACTV_CODE_PREV means the previous active records.

- S_START_TIME is the time of S_DATETIME when a S_ACTV_CODE starts

- S_END_TIME is the time before a S_ACTV_CODE changes to another S_ACTV_CODE

- For the first record, S_ACTV_CODE is null, so there is no S_ACTV_CODE_PREV, so S_ACTV_CODE_PREV is NULL

- For the second record S_ACTV_CODE has some value, but S_ACTV_CODE_PREV is NULL for first record. So second record S_ACTV_CODE_PREV is also NULL

- For the last record (means S_ACTV_IND = 1), the user is currently working on it and S_ACTV_CODE is not changed. So S_END_TIME is a open time and we want to keep it as NULL

So the result should be as below:

AAA-111 NULL NULL USER1 2015-06-15 00:21:06
2015-06-15 00:21:07 1
AAA-111 NULL 2 USER1 2015-06-15 00:21:07
2015-06-17 03:20:33 183566
AAA-111 2 4 USER2 2015-06-17 03:20:33

SQL Server 2012 :: Calculate Elapsed Time And Display As Row In Results

Jun 19, 2015

I am trying to calculate the time difference between the value in the row and the min value in the table. So say the min value in the table is 2014-05-29 14:44:17.713. (This is the start time of the test.) Now say the test ends at 2014-05-29 17:10:17.010. There are many rows recorded during that start and end time, for each row created a time stamp is created. I am trying to calculate the elapsed time and have it as a row in the results.

min(timestamp) - timestamp(value in row) = elapsed time for that test
where Channel = '273'

Here is the table DDL

USE SpecTest

CREATE TABLE [dbo].[Spec1](
[Spec1ID] [int] IDENTITY(1,1) NOT NULL,
[Channel] [int] NOT NULL,

[Code] ....

Here is some dummy data to use

INSERT INTO Spec1 (Channel, Timestamp, Lambda, Power)
VALUES(273, '2014-05-29 14:44:17.713', 800, '-64.91');
INSERT INTO Spec1 (Channel, Timestamp, Lambda, Power)
VALUES(273, '2014-05-29 15:05:09.507', 800, '-59.11');
INSERT INTO Spec1 (Channel, Timestamp, Lambda, Power)

[Code] ....

Example desired results (I hope the formatting works)

Channel | Timestamp | Lambda | Power | Elapsed_Time
273 | '2014-05-29 14:44:17.713', | 800, | '-64.91' | 0
273 | '2014-05-29 15:05:09.507', | 800, | '-64.91' | 00:20:51
273 | '2014-05-29 15:26:00.520', | 800, | '-64.91' | 00:41:42
273 | '2014-05-29 16:28:34.213', | 800, | '-64.91' | 01:44:16
273 | '2014-05-29 16:49:25.853', | 800, | '-64.91' | 02:05:08

I have to calculate the Total number of days present and absent for a singel student.

AS of now i have 3 tables.

1.Daily attendance - Columns -[Guid][,AcademyId],[StudentId],[Date],[Status],[Reason]
2.Student details - Columns - [Guid],[FullName],[DOB],[Address]
3.Class Details - Columns - [Guid],[AcademyId],[Class],[Section],[Startdate],Enddate]

So now i have loaded all the data into the table.

I can fetch the counts for total present and absent

Query i have tried is

@StudentId Uniqueidentifier ='0B2D4D41-8D33-4D79-A981-03E0F093F458'
select A.StudentId ,A.Date,Count(Date)Total,B.Guid,

AS result of this query i get the data.Present count and Absent count from date inserted in Dailyattendance tables.

SO my problem is if the student have promoted to next class then by this query it will count the before year also how do i need to calculate the count according to the Class StartDate and Enddate as i mention in the Class Details table what will be the query.

SQL Server 2012 :: Calculate Number Of Groups And Group Size With Multiple Criteria

Jun 15, 2015

I need to calculate the last two columns (noofgrp and grpsize) No of Groups (count of Clientid) and Group Size (number of clients in each group) according to begtim and endtime. So I tried the following in the first Temp table

GrpSize= count(clientid) over (partition by begtime,endtime) else 0 end
and in the second Temp Table, I have
,NoofGrp=count(distinct grpsize)
From Temp1

The issue is for the date of 5/26, the begtime and endtime are not consistent. in Grp1 (group 1) all clients starts the session at 1030 and ends at 1200 (90 minutes session) except one who starts at 11 and end at 1200 (row 8). For this client since his/her endtime is the same as others, I want that client to be in the first group(Grp1). Reverse is true for the second group (Grp2). All clients begtime is 12:30 and endtime is 1400 but clientid=2 (row 9) who begtime =1230 but endtime = 1300. However, since this client begtime is the same as the rest, I wan that client to be in the second group (grp2) My partition over creates 4 groups rather than two.

SQL Server 2012 :: Calculate Failure Rates Of Systems Based On Cases Opened Through Support

Jun 5, 2014

I am trying to build a query which will be used in an automated report to calculate failure rates of systems based on cases opened through support. Here is where I am stuck. Some systems may have multiple cases opened within the same span of another cases however we would consider this one failure:

System ACase12013-07-11 13:17:09.0002013-07-15 12:05:03.000
System ACase22013-07-12 16:27:50.0002013-07-12 16:29:12.000
System ACase32013-07-12 17:30:32.0002013-07-12 17:40:11.000
System ACase42013-07-12 19:00:24.0002013-07-12 19:04:14.000
System ACase52013-10-01 18:02:23.0002013-10-01 18:11:26.000

Lets say System A generated those 5 cases however Case 2,3 and 4 all happened within the same period as Case 1 so those 4 cases should count as one failure so my end result should be

System ACase12013-07-11 13:17:09.0002013-07-15 12:05:03.000
System ACase52013-10-01 18:02:23.0002013-10-01 18:11:26.000

And that system should show me 2 failures. I was thinking of using a temp table but not sure if that is possible as I am stumped on how to compare the dates to be able to validate if they fall within the range of an older case and whether or not to include them into the new Temp Table.

Mirroring Over Distance????

Mar 1, 2007

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.

Any comments??

Cluster Euclidean Distance

Mar 27, 2007

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).

ClusterDistance() could be Y but what will be X.

Find Data Within 10m Distance Of Coordinates?

Nov 22, 2013

I am trying to write a piece of SQL which gives me a list of enquiries within 10 metre distance of a enquiry.

The idea is to identify possible duplicates.

Table: enquiry

Primary key: enquiry_number

Co-ordinates data fields: enquiry.enquiry_easting and enquiry.enquiry_northing.

I will need to self-search on the same table to find possible enquiries within 10m distance.
