Transact SQL :: How To Get Top 5 Based On A Category
Jun 4, 2015
I have this following query,
select [Parent Name],[ID],[Year],[Sales Name],
sum([Total VtM]) as 'Total Sales'
from RegData
group by [Parent Name],[ID],[Year],[Sales Name]
order by [Total Sales] desc
I need to modify this query to get the top 5 of each category based on Total Sales amount.
and I need to create a session temp table (eg ##output) that translates the calculation (NewAmt - OldAmt) into categories such as
"decrease -201 to -500" "decrease -1 to -200" "no change" "increase 1 to 200" "increase 201 to 500"
so that my final output would look like this:
ID NewPer NewAmt OldPer OldAmt Change ChangeCategory 334 1/07/08 200 22/01/08 200 0 no change 2396 1/07/08 4000 10/12/07 3600 400 increase 201 to 500 7650 1/07/08 1100 07/07/06 1200 -100 decrease -1 to -200 . . . I understand how to add the "Change" column to my temp output table, but am struggling with the ChangeCategory column - can someone point me in the right direction?
I have an assignment to make a library. Right now I'm at the point of implementing business rules. One is that I need to create a trigger that won't allow a member to exceed a certain number of loans at a time, based on their category (student = 5, Teacher =10 and Researcher = 20).
I can link a product to a category. Now, if I just link a product to a single category, such as the bottom leaf category:
Self Help / Personal Development / Spiritual / Meditation
I would link a product to the Meditation category. However if I click on Self Help while browsing, I want to see all items underneath Personal Development, Spiritual and Meditiation. So my question is is this a good way to store the product-category relationships, or should I put many entries into CategoryProducts to keep the queries simlpe and faster? Are they faster doing it this way? In this way there would be 4 entries for a product in meditation. My personal idea is that adding all entries up a tree arm of a category path will be cumbersome to manage, but it does solve the problem of clicking on Self Help and seeing all products that exist within sub-categories. I am sure an SQL query would be able to work this out, but I dont know if performance would be something to consider on an ecommerce site? Are there any patterns fo rthis stuff - seems a reasonably repeatable pattern for business sites?
I used to do this with classic asp but I'm not sure how to do it with .net.Basically I would take a table of Categories, Then I would loop through those. Within each loop I would call another stored procedure to get each item in that Category. I'll try to explain, Lets say category 2 has a player Reggie Bush and a player Drew Brees, and category 5 has Michael Vick, but the other categories have no items.Just for an example.. Category Table: ID Category1 Saints2 Falcons3 Bucaneers4 Chargers5 FalconsPlayer Table:ID CategoryID Player News Player Last Updated1 1 Reggie Bush Poetry in motion 9/21/20062 1 Drew Brees What shoulder injury? 9/18/20063 5 Michael Vick Break a leg, seriously. 9/20/2006 Basically I would need to display on a page:SaintsReggie BushPoetry in MotionFalconsMichael VickBreak a leg, seriously.So that the Drew Brees update doesnt display, only the Reggie Bush one, which is the latest.I have my stored procedures put together to do this. I just don't know how to loop through and display it on a page. Right now I have two datareaders in the code behind but ideally something like this, I would think the code would go on the page itself, around the html.
Display customized data based on customized where statement from UDT.
The UDT is a parameter inside of a stored procedure.
Problem:
A parameter from a stored procedure is @communication communications readonly
This parameter is a User-Defined Table Types (UDT) It contains criteria based on end-user's selection from a filtration functionality from a webpage.
Four example of filtration critera based on four end-users' selection that is located inside of a table below.
Each UDT table contains different criteria:
Number Criteria ------ -------- 1 Phone 3 Email
Number Criteria ------ -------- 1 Phone 2 Cellphone 3 email
Number Criteria ------ -------- 4 None
Number Criteria ------ -------- 2 Cellphone 1 Phone
Is it somehow possible to use the criteria's value as a column name in the where statement? I want to filtrate the data of the table datatable based on id, name and the UDT's criteria.
I was enable to apply the criteria inside of a variable by looping the UDT's table but the next thing is to paste it in the where statement after "id=1 and name" below
select * from datatable where id = 1 and name = 'Cost'
How should I do it?
[URL] .....
create table datatable (id int, name varchar(100), email varchar(10), phone varchar(10), cellphone varchar(10), none varchar(10) );
I am looking for some study meaterial focussed on performance based transact SQL development. I am a fairly well seasoned (3+ years self taught), and I am getting into situations where different query constructs yield the same results, but the performance (execution time and disk I/O) varies.
I have found that sometimes nested select statements execute faster than joins, but usually the opposite is true, for example, and I would like to learn why.
TeamStatus T 1 Complete or Escalate T 2 Pick Up T 2 Resolve Case T 1 Pick Up T 1 Complete or Escalate T 1 Pick Up T 1 Complete or Escalate
I want to get he group based of Resolve Case value in Status Column. Anything before Resolve case will be considered as Group 1 and after Resolve Case status should be considered as Group 2. Below is desired new Group column,
Group TeamStatus Group 1 T 1Complete or Escalate T 2 Pick Up T 2 Resolve Case
Group 2 T 1Pick Up T 1Complete or Escalate T 1 Pick Up T 1 Complete or Escalate
I have conducted a thorough search in the forums and cannot quite find my answer. I have a date field called open_date. If the open_date is more than 30 days old, I need to count it. I have started with the following code:
SELECT 'Older_Than_30Days' = CASE WHEN open.date >= 30 THEN '1' ELSE '0" END
Here we need consider patient dates that fall between sdate and edate of the patientrefs table, and then we need to consider the highest status values in order (for example, the highest values in order - 2 is first highest, 4 is second highest, 3 is third highest, and 1 is fourth highest value)
If the date falls between multiple different sdate and edate with the same status values, then we need to consider the latest sdate value and from that entire record we need to extract that value.
Here, pn=2 values have dates which fall between sdate and edate of patientref table. Then we give highest values status is 2, and status 2 values have two records, then we go for max sdate(latest sdate). Then this pn=2 latest sdates is 2015-02-10 and we need to retrieve the corresponding edate and status values.
pn = 4donot have sdate and edate and status values dut not fall conditon
select p.pn,p.code,p.[date],p.doctorcode,pr.sdate,pr.edate,pr.[status] from patient p outer apply (select top 1 pr.pn,pr.code,pr.sdate,pr.edate,pr.[status] from patientref pr where pr.pn=p.pn and pr.code=p.code and p.date between pr.sdate and pr.edate order by case when pr.status=2 then 1 when pr.status=4 then 2 when pr.status=3 then 3 when pr.status=1 then 4 end ,pr.sdate )pr
but this query not given expected result.here when dos not fall between sdate and edate that records not given in the above query. I required that records also.if not fall b/w condition then we need retrive that records empty values for that records.
I'm running into an interesting issue when returning a response from an XML-based web service. The following code returns good values from PRINT
@response DECLARE @address varchar(50) = '90210' DECLARE @URL varchar(MAX) SET @URL = 'https://somewebsite/map.xml?zip=' + CASE WHEN @Address IS NOT NULL THEN @Address ELSE '' END SET @URL = REPLACE(@URL, ' ', '+')
[code]...
However, on some calls to the web service, the value returned is longer than 4000 characters. In these instances, it appears as though it breaks the whole thing and returns nothing. However, if I change the @Response parameter to nvarchar(max), it never returns anything, even on responses that are shorter than 4000 characters. what the fundamental difference is here between nvarchar(4000) and nvarchar(max) with respects to how it stores responseText. More importantly, how to get this to return a value even when it exceeds 4,000 characters?
how to separate names but i cannot make work in this case. The name field might contain anywhere from only one name with no delimeters to five names with four delimeters. I want to replace the delimeter with a space and reorder the names.
Original data format: Name2/Name1/Name3/Name4/Name5. Desired data format: Name1 Name2 Name3 Name4 Name5. Examples of source data

I want to frame a range of data based on particular group of columns
If OBJECT_ID('tempdb..#ResellerRange') IS NOT NULL drop table #ResellerRange create table #ResellerRange ( ResID varchar(10) , amt decimal(18,2) , serialno int)
insert into #ResellerRange ( ResID,amt, serialno ) values ('Raja',10,67),('raja',10,68),('raja',10,89),('Prabu',20,56)
I want below output
resid amt min max ---------------------------------- raja 10 67 68 raja 10 89 89 Prabu 20 56 56
I have a simple following table which is having only one date column.
CREATE TABLE TEST_DATE ( InputDate DATE ) GO INSERT INTO TEST_DATE VALUES('01-01-2015') INSERT INTO TEST_DATE VALUES('06-25-2015') INSERT INTO TEST_DATE VALUES('11-23-2014') GO SELECT * FROM TEST_DATE;
And the expected out put would be as follows:
I want to derive a Four Quarter End Date based on Date selected.
For Example if i select 01-01-2015 then First Quarter End Date would be Previous Quarter End Date Second Quarter End Date would be Current Quarter End Date Third Quarter End Date would be Next Quarter End Date Fourth Quarter End Date would be Next +1 Quarter End Date Like that
My source table has two columns... Policynum and PolicyStartdate and data looks like.. . Policynum PolicyStartdate 123G 01/01/2012 456D 02/16/2012 789A 01/21/2012 163J 05/25/2012
Now my output should return based on 3 parameters..
First two parameters are date range... let say @fromdt and @todt
Third parameter is @policynum
Scenario-1: Enter dates in date range param and leave policynum param blank Ex: policystartdate between '01/01/2012 and '01/31/2012'.... It returns 1st and 3rd rows from above in the output
Scenario-2: enter policy num in policynum param and don't select any dates Ex: policynum ='456D' It returns 2nd row in the output
Scenario-3: Select dates in date range param and enter policynum in param Ex: policystartdate between '01/01/2012 and '01/31/2012' and policynum ='163J'. it should return only 4th row even though dates were selected(Override date range when policynum is entered in param and just return specified policynum row in the output)
There are two seperate jobs,Job A and Job B, which run and insert records in a table. Job A runs first and then Job B runs. The task is to overwrite Job B records if Job A and Job B have same
I basically want to select all GRNID's from one table but they have to be between dates in another table.So I want all GRN's between two dates found in the ABSPeriodEndDate table. To find out the start date for the between clause I need to find the MAX Period then minus 1 and the max year. To find the end date of the between clause I want I need to find both the max period and year. But I want the DateStamp column to return the results for the between clause. My query is below:
SELECT tblGRNItem.GRNID FROM tblGRNItem INNER JOIN ABSPeriodEndDates ON tblGRNItem.DateCreated = ABSPeriodEndDates.DateStamp WHERE tblGRNItem.DateCreated BETWEEN (SELECT ABSPeriodEndDates.DateStamp FROM ABSPeriodEndDates WHERE ABSPeriodEndDates.DateStamp = (SELECT
I am trying to calculate the the running total but also tried to reset to reset to zero based on a value of a column.
here I am trying to calculate the value of CalcVal column based on column Flag value...actually it is running total but it reset to zero if Flag value is 0.
Here is the example of data along with required column
I have either 2 or 1 row for each customer number I want to write a SQL to pull data into 1 table based on same CustomerNumber, if only one row is present for the particular customer number it should pull null in FName2,LName2,DOB2 columns.
example: CustNumber Fanme Lname DOB 1 Sam tiller 08/26/1981 1 Joe timy 01/02/1986 2 jack niks 09/09/1990
Result I want: CustNumber Fname1 Lname1 DOB1 Fname2 Lname2 DOB2 1 Sam Tiller 08/26/1981 Joe timy 01/02/1986 2 Jack niks 09/09/1990 null null null
I am trying to break down the content based of hourly basis. It works fine when there are values for that specific hour but if there are entries or values for a specific hour then it returns null instead of 0. How not to get null instead get zero.
Here is the code below:
