I have data concerning sale of several products, columns are two : Name_product, Purchase_day
I need to calculate with SQL the average duration (number of days) to purchase again the same product among the products
As in example, one product can be bought many times, so this product we will see it repeated several times at different days "Purchase_day" so here we can have Duration between each two successive purchases for the same product, but for the last purchase of this product the duration until today will be the day of yesterday minus the last day of purchase, and finally the average duration of this product will be the sum of all duration of this product / number of all duration of this product.
The SQL server 2005 is needed to be put for user's access as database backend for VB.net application. We need only one system for development. Which is best suited for our application?
I need to find the last purchase price for each product. Â If I run the following code, I correctly get 1 result for each productID and the last purchase order number.
SELECT pod.article as ProductID,max(pod.order_ID) as LastOrderfrom apodetail podgroup by pod.articleorder by pod.article
Now I need to add in the price for that product on that orderID. Â I've tried the following self join query, tried it without the join, and tried adding DISTINCT, but they all return more than 1 row per ProductID.
SELECT pod.article as ProductID,max(pod.order_ID) as LastOrder,pod2.rev_price as UnitPricefrom apodetail podjoinapodetail pod2on (pod2.order_ID = pod.order_id)group by pod.article,pod2.rev_priceorder by pod.article
How can I get it to simply add the price to the first query?
I am storing duration of a lot of jobs in a column in a table per job. This duration is in seconds and an integer datatype.
Sample data: Job     Duration   date Job1    25      2015/9/23 Job2    30      2015/9/23 Job3    45      2015/9/23 Job4    1       2015/9/22
Now I need to get average duration per day for every month. Is this possible? I have a calendar table that has every single day month year microsecond millisecond  second minute and hour.
I have a table with product_name and introduction_date(when the product was first introduced)as columns. now i wana calculate average as below
if item is sold in previous business year(suppose 2011-12) then avg should be avg price in businessyear(2010-11), if it is newly introduced(suppose 2013-14)then avg should be of current year(2013-14).
Which works fine, but what I need to calculate the total duration of a request based on the duration of the tasks completed in the request based on Req_ID. I would like to use the CASE statement I have to determine the SLA_Mins for each task and add them together to get total request SLA_Mins.
Below is the create table schema and data
GO /****** Object: Table [dbo].[MidrangeOtherSourceControl] Script Date: 06/03/2015 18:13:15 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[MidrangeOtherSourceControl]( [Req_ID] [float] NULL, [Service_Name] [nvarchar](255) NULL,
I am using the code below to get all the children of a particular product and it is working fine. How to get the particular product's id in the select statement. for example, i need to show 891 in a separate column for all the records returned by the query below.
DECLARE @Hierarchy TABLE (Product_Id INT, Parent_Product_Id INT) INSERT INTO @Hierarchy VALUES (123, 234) INSERT INTO @Hierarchy VALUES (234, 456) INSERT INTO @Hierarchy VALUES (456, 678) INSERT INTO @Hierarchy VALUES (678, 891) INSERT INTO @Hierarchy VALUES (891, NULL)
Calculation of an average using DAX' AVERAGE and AVERAGEX.This is the manual calculation in DW, using SQL.In the tabular project (we're i've noticed that these 4 %'s are in itself strange), in a 1st moment i've noticed that i would have to divide by 100 to get the same values as in the DW, so i've used AVERAGEX:
The results were, respectively: 701,68; 2120,60...; -669,441; and  finally **-694,74** for Avg_FMPdollar.i can't understand the difference to SQL calculation, since calculations are similar to the other ones. After that i've tried:
test:=SUM([_FMPdollar])/countrows('Fct Sales') AND the value was EQUAL to SQL: -672,17 test2:=AVERAGE('Fct Sales'[_Frontend Margin Percent ACY]), and here, without dividing by 100 in the end, -696,74...
So, AVERAGE and AVERAGEX have a diferent behaviour from the SUM divided by COUNTROWS, and even more strange, test2 doesn't need the division by 100 to be similar to AVERAGEX result.
I even calculated the number of blanks and number of zeros on each column, could it be a difference on the denominator (so, a division by a diferente number of rows), but they are equal on each row.
I have a temp_max column and a temp_min column with data for every day for 60 years. I want the average temp for jan of yr1 through yr60, averaged... I.E. the avg temp for Jan of yr1 is 20 and the avg temp for Jan of yr2 is 30, then the overall average is 25. The complexity lies within calculating a daily average by month, THEN a yearly average by month, in one statement. ?confused?
Here's the original query. accept platformId CHAR format a6 prompt 'Enter Platform Id (capital letters in ''): '
SELECT name, country_cd from weather_station where platformId=&&platformId;
SELECT to_char(datetime,'MM') as MO, max(temp_max) as max_T, round(avg((temp_max+temp_min)/2),2) as avg_T, min(temp_min) as min_temTp, count(unique(to_char(datetime, 'yyyy'))) as TOTAL_YEARS FROM daily WHERE platformId=&&platformId and platformId = platformId and platformId = platformId and datetime=datetime and datetime=datetime GROUP BY to_char(datetime,'MM') ORDER BY to_char(datetime,'MM');
Would you mind advising me on what sql server license would be suitable? What I am concerned about having is the ability to access a database from 10 computers. I like to use the Enterprise Manager, Query Analyzer, write proceduers, Views and Triggers. Not sure if this affects anything.
I need to purchase a new computer for a small medical clinic which will basically only have one purpose: to answer to read and write queries to a SQL Server 2005 which is resident on that computer. Queries come from the current 8 stations (up to 14 stations in the future). Most of the time, only 3 stations will be active at a time. Queries are mostly to access patient file information, are not complex and are short-lived.
A friend of mine who owns a computer store just quoted me for a dual quad-core Xeon 5405 2GHz system with Windows Server 2003 10 Cals. I'm concerned about the following: - What's the use in having 8 cores, each of them running at only 2GHz, when there's really only one service running (SQL Server 2005, likely Express Edition) on the computer. Does SQL Server have the capability to make use of all cores? Otherwise, why spend more for Xeon and so many cores instead of a single C2D running at a faster speed of say 3GHz ? - What would be the advantage of using a Windows Server over Windows XP in a peer-to-peer configuration? I don't buy into the 10 connection limit because the TCPIP.sys file can be altered to move that limit up, so 14 stations does not trigger the need for Windows Server in and of itself.
I went in to waterstones today to try and get a copy of sql pocket reference (o'riely publishers i think) but there were none in stock, as the new edition is out on the 31st.
so i bought sam teach urself sql "in ten minutes"
unfortunately it covers the alter tag but not its use to modify columns >:(
I'm a bit stuck with this one atm --------------------------------------- 1> alter table news modify ( dateadd varchar(80)) 2> go Msg 170, Level 15, State 1, Server NEIL, Line 1 Line 1: Incorrect syntax near '('. 1>
I am looking for a good reference on hardware specs for a dedicated SQL server. I don't want to talk to vendors, because I'm not looking to get snowed. Does anyone know of any resources? The server is to be a dedicated dataserver, for about 300 clients.
My company is planning to purchase a SQL2005 standard Processor license (unlimited users - about $5000)
Does anyone know if we can obtain SQL2000 media along with the purchase. Because of the app we are running and its stage of development, we have to install and run SQL2000 for about 6 months before we can run Sql2005. We dont want to purchase SQL2000 for such a short term use.
I asked a DELL rep to help me with this over a month ago and he still has no answers for me.
Hi, I am new at SQL hopefully this would be a rather easy question for you guys to help me out with. I have a table called PRODUCT with the following fields: a. Product Name b. Product Dept. c. Purchase Date.
I would like to run a query to obtain all rows tha has more than one purchases on any particular day.
i use microaccess create table, there is a filed call"Complete_PO", value"yes/no" i wrote following statement to select it, but at runtime, there is warning message"...constraint...one or more row violating non-unique and so so..." how to solve it SqlSelectCommand2.CommandText = "SELECT Complete_PO FROM [PURCHASE ORDER] WHERE [PO_No] Like '%" & GetYearCode() & "%' ORDER BY Right(PO_No,4) desc" PoNum_SqlDataAdapter.Fill(PO_DataSet1) TextBox1.Text = PO_DataSet1.Tables("PURCHASE ORDER").Rows(0).Item("Complete_PO").ToString()
i query a purchase order table, there is one column called PO_No, format: LP-0245111-0004 i make following statement to query: the middle code act as my id, using it search my records, the last 4 digit used to find the last purchase order number SqlSelectCommand2.CommandText = "SELECT PO_No FROM [PURCHASE ORDER] WHERE PO_No Like '%" & GetYearCode() & "%' ORDER BY Right(PO_No, 4) DESC" i checked my database, last record is LP-0545381-0300 in my debuging process, surprisingly found that selected record is LP-0545381-301 ! any one hav any suggestion? ^_^

I asked a DELL rep to help me with this over a month ago and he still has no answers for me.
I have a table set of records. Its contains some customerID,SportsGoods,Price in different datetime. I want to add customer spent. If crossed 1000 means i have to show purchase time when it is crossed 1000. I need query without while and looping.
I need to write down a sql query wherein in one particular day(user will enter manually), i need to find out a 15 minutes slot wherein purchase order's created or updated are the highest.
i.e. out of 96 slots(15 minute slot each)-I need to find the slot which has maximum number of Purchase orders created or updated.
INSERT INTO PurchaseOrder (PurchaseOrderDate, SupplierID) VALUES(@date, @SupplierID)
END
SET @POno = @@IDENTITY
RETURN
However, how do i make it that it will automatically adds item under the POno being gernerated? can i use a trigger so that whenever a Insert for PO is success, it automaticallys proceed to adding the items into the table PurcahseOrderItem?
If monitoring for duration with sql profiler, what does the number represent ie 2733906 is it milliseconds, thousandths, looked in BOL no clear definition
I found this nifty code on stackoverflow that works well but I'm trying to send the results to a text file and the column lengths are huge. I used CAST for the first line and it worked great but I can't seem to make it work with duration. Here's the original code:
I am trying to get a query that will allow me to report the time taken to complete a certain training module.
The database itself does not have a duration field so I am tring to get the duration by using MIN and MAX. I can get the timing for when the module was opened and the time for the last mouse click on it, from this I need to be able to calculate the time taken to complete.
Query I am using to get the basic info comes from 3 tables so I have only attached the relevent output. Query used is as follow:
SELECT * FROM PPS_SCOS, PPS_TRANSCRIPTS, PPS_TRANSCRIPT_DETAILS, PPS_PRINCIPALS WHERE PPS_SCOS.SCO_ID = PPS_TRANSCRIPTS.SCO_ID AND PPS_TRANSCRIPTS.TRANSCRIPT_ID = PPS_TRANSCRIPT_DETAILS.TRANSCRIPT_ID AND PPS_TRANSCRIPTS.PRINCIPAL_ID = PPS_PRINCIPALS.PRINCIPAL_ID AND PPS_SCOS.NAME LIKE 'MTM-106 The Dangers of Smoking' AND PPS_PRINCIPALS.NAME LIKE 'Nigel Cordiner' AND PPS_TRANSCRIPTS.TICKET NOT LIKE 'l-%' ORDER BY PPS_TRANSCRIPT_DETAILS.DATE_CREATED
Output:

Have added the column heading and the tables the output comes from.
Relatively new to SQL so any help would be greatly received.
SELECT h.JobNum, (CASE WHEN MONTH(h.JobCompletionDate) = 1 THEN datediff(day,MIN(l.ClockInDate),MAX(l.clockInDate)) ELSE 0 END) AS JAN, (CASE WHEN MONTH(h.JobCompletionDate) = 2 THEN datediff(day,MIN(l.ClockInDate),MAX(l.clockInDate)) ELSE 0 END) AS FEB, ... FROM JobHead h INNER JOIN LaborDtl l ON h.JobNum=l.JobNum WHERE JobCompletionDate>='20070101' AND JobCompletionDate <'20080101' AND l.ClockInTime<>0 GROUP BYh.JobNum ,h.JobCompletionDate
The query shows, for each job, the month in which the job completed, and the number of hours it took to complete. I€™m calculating the number of days€™ duration by doing a datediff between the oldest and newest clockindates. I need to ignore adjustment transactions in the labordtl table €“ these rows are easily identified as they have clockintime values of 0. So far, so good. Now here€™s my problem.
There are some jobs which have only one €œreal€? labor transaction €“ this could happen if the job only took one day to complete. Other labor transactions may exist for that job, but let's say they are adjustments which we can ignore -- the date they were entered should not extend the duration of the job. In this situation, my datediff between the oldest valid transaction and the newest, returns 0. I don€™t have to count hours between clockintime and clockouttime. The rule is simply that if there is only one "real" labor transaction, I need to count this as a 1 day job.
I thought a nested CASE statement or expression might be the way to go but I didn't make any real progress.
Any ideas to solve this problem would be appreciated.
I'm developing a web app that displays the running packages and the total elapsed time. I'm calling GetRunningPackages() method and using the ExecutionDuration property of the returned package. The duration seems to be only for the currently executing container and not the entire package. Is there a way to get the duration of the entire package? Thanks.
Hi all, I want to find working duration between two datetimes in c#.i'm using following code... DateTime starttime = Convert.ToDateTime(Session["StartTime"]); DateTime endtime = DateTime.Now; TimeSpan duration = endtime - starttime; DateTime period = new DateTime(duration.Ticks); i want to store this duration in database through stored procedure, i've give datetime datatype to duration but it is giving error in conversion of TimeSpan to DateTime..Please help... Thanks
SQL 6.5 - run duration 6-7 hours SQL 7.0 - run duration 12-13 hours 175+ columns with total record size=570 4.2M records with tablesize 2.5G
It's a simple 'select into...' with some embedded logic from a work table with all char fields into the actual table converting char fields into various data types (int, datetime, real, etc.) Here is a sample of the code:
SELECT LoanNum=CASE WHEN ISNUMERIC(ACCT#)=1 THEN CONVERT(int,ACCT#) ELSE NULL END, PaidToDt=CASE WHEN PAIDDT = '0001-01-01' THEN NULL WHEN ISDATE(PAIDDT)=1 AND SUBSTRING(PAIDDT,1,2) = '19' THEN CONVERT(smalldatetime,PAIDDT) WHEN ISDATE(PAIDDT)=1 AND SUBSTRING(PAIDDT,1,2) = '20' AND SUBSTRING(PAIDDT,3,2) < '79' THEN CONVERT(smalldatetime,PAIDDT) ELSE NULL END, . . . INTO db.owner.tablename FROM db.owner.wrktablename (NOLOCK)
Hearing complaints from users about speed on db server (I have almost no control on design) it just has to work. Ran profiler looking for all sql statements over 4000 millsec and in one hour returned over 715 tsql statements. Over 300 of these were over 10000 milliseconds. THis is on an 8 way Dell with 8 gig of RAM. Looking for opinions, how bad does this look compared to other servers you are taking care of? Cache hit ratio is at 99 % and system queue length still under 1, but this does not look good.
There is a trigger to monitor the modification on a table, and it turn on. For a special duration, I need to turn off this trigger to modify the table. And then turn on the trigger again.
