T-SQL (SS2K8) :: Distribute Data Into Groups Based On Existing Numbers?
Aug 11, 2014
i've been looking at moving one of our processed from excel (+vba) into t-sql to make life easier but am stuck.
We have lots of tasks that are assigned to work groups which we want to distribute evenly across the work groups. This is a simple task for ntile.. However when these tasks are no longer required they are removed which leaves the groups uneven. When new tasks are added we want to still try to keep these groups balanced.
Create table Jobs(jobid int identity(1,1), name varchar(100),Groupid int)
--Existing tasks
Insert into Jobs(name,Groupid) values ('Task1',1)
Insert into Jobs(name,Groupid) values ('Task2',1)
Insert into Jobs(name,Groupid) values ('Task3',1)
Insert into Jobs(name,Groupid) values ('Task4',1)
Insert into Jobs(name,Groupid) values ('Task5',2)
Insert into Jobs(name,Groupid) values ('Task6',2)
Insert into Jobs(name,Groupid) values ('Task6',2)
Insert into Jobs(name,Groupid) values ('Task7',3)
-- New tasks
Insert into Jobs(name) values ('TaskA')
Insert into Jobs(name) values ('TaskB')
Insert into Jobs(name) values ('TaskC')
Insert into Jobs(name) values ('TaskD')
Insert into Jobs(name) values ('TaskE')
Insert into Jobs(name) values ('TaskF')
This gives us 6 unassigned tasks and a uneven group assignment
I have a Systema that uses a DataBase an I Want to Install y other machines, I need to Install a Visual Studio Program that uses a Database, How do I Install The Visual Studio Program, the Sql Server Express, and the existing DataBase.
How to count the number of values that exist in a row based on the values from an array of numbers. Basically the the array of numbers I want to look for are in row 1 of table [test 1] and I want to search for them and count the "out of" in table [test 2]. Excuse me for not using the easiest way to convey my question below. I guess in short I have 10 numbers and like to find how many of those numbers exist in each row. short example:
I have written a merge Statement where i am facing trouble to delete the data basing on Where Clause Condition.
1) Case 1 : For example i have inserted Data from Source to Target based on Date Key Condition.Take an Instance 10 Records Inserted. 2) Case 2 : For example some changes in the records and it has been updated through the Merge Statement . 3) Case 3 : For the Same Date key based on Conditions now three records has came and need to be inserted and rest should be deleted for that Date Key.
How i need to proceed on this before 10 records are not getting deleted and new records adding for that one
My Example Code :
MERGE INTO TargetTable AS Target USING ( SELECT DISTINCT Col1, Col2 FROM Table1 AS cga ) ON dad.AnchorDate = CASE
My current report has around 40 subreports corresponding to tests executed by the user. There is a different sub report for each of the tests executed. I first developed the report by just putting the subreports directly on the main report. The problem is if some of my tests are not executed by the user I would like the subreports to not appear in the report.
I have tried doing this two different ways. First I tried creating a table and attaching that table to a dataset that I created that returns all the tests that were executed by the user. I then set up a filter that specified that the name for a specific subreport had to equal the test name. I then dropped the sub report for that particular test into the table. The idea is there would only be one row when data is available and no rows when no data is available so the subreport would not appear. When the data is available the subreport appears great. When it is not available and there is no item in the dataset for that test I get an error from SQL that states there was an internal reporting error and to check the SQL server log for more information. I know my table is set up correctly because when I replace the subreport with text the text will appear only if data is available for that test and the text does not appear if no data is available. I get no errors until I add the subreport and remove the data from the database so the filter does not return any items. Is there a reason why I would be getting this error? I am still pretty green using reporting services so I do not even understand how to get the log from the server to determine why this error is occuring.
Secondly I have tried to use an expression to hide the subreport using the visibility tab for the report. I was able to get this to work by creating a dataset that returns 1 if a specific test has been executed and no rows if not. I then created an expression that would return true if the dataset returned 1. This worked okay in hiding my subreport but I would then have to create 40 datasets, one for each test. Is there anyway to write an expression that would return true if a dataset contained a row with a specific test name? I have not been able to figure this out.
Can someone either help me fix the problem I am having with the table approach or write an expression that would work in the visibility setting for each sub report that did not require 40 datasets? Or is there another approach that I am not even thinking of that might work?
To give you some context we have a new amendments application (nothing fancy, excel based with SQL Server back end) that allows users to submit amendments to product data (Product Info, PO Prices, Dates etc.). There is also an admin tool that a team uses to action these amendments in the various systems.
The old version of this tool, users submitted amendments by style and could if need be submit multiple amendments against one product at the same time. The new tool, I believe for audit reasons, users submit by amendment type, so for example I would submit a cost price change for a given style.
The issue now is that on the occasions where a user has multiple amendments, they now come through separately. So cost price would be Amendment 1 and a date change would be amendment 2 even though they could be the same product. This could potentially mean that the admin team would be duplicating work if the paperwork is updated and sent after each amendment, whereas before they would make both changes and only send the paperwork once.
Having not built either of these tools, I've been tasked with trying to fix this, my two thoughts being either to amend the user form to somehow capture/ allow users to submit amendments together or try to use the existing data and doing the grouping dynamically in the back end. Use that lag to look at grouping any submitted amendments that occur within 30mins of the first occurrence of that style
This grouping would then be given a joint time so when the 'time lag' period passes the amendments will be visible together.I've tried a few things and a few head on desk moments trying to get a set based approach but haven't been able to get where i want, its either an issue where amendments span an hour, such as 9:59 and then 10:03 or grouping together amendments that happen after the 30mins of the first one.
Here is some sample data
USE FF_Winning_Together; IF OBJECT_ID(N'tempdb..#AmendTest',N'U') IS NOT NULL DROP TABLE #AmendTest; CREATE TABLE #AmendTest ( AmendmentIDINT IDENTITY(1,1)NOT NULL, StyleCHAR(1)NOT NULL, AmendmentStatusVARCHAR(10)NOT NULL, DTDATETIMENOT NULL
create table #myfirst (id int, city varchar(20)) insert into #myfirst values (500,'Newyork') insert into #myfirst values (100,'Ediosn') insert into #myfirst values (200,'Atlanta') insert into #myfirst values (300,'Greenwoods') insert into #myfirst values (400,'Hitchcok') insert into #myfirst values (700,'Walmart') insert into #myfirst values (800,'Madida')
-- My Second Data
create table #mySecond (id int, city varchar(20),Sector varchar(2)) insert into #mySecond values (1500,'Newyork','MK') insert into #mySecond values (5500,'Ediosn','HH') insert into #mySecond values (5060,'The Atlanta','JK') insert into #mySecond values (7500,'The Greenwoods','DF') insert into #mySecond values (9500,'Metro','KK') insert into #mySecond values (3300,'Kilapr','MK') insert into #mySecond values (9500,'Metro','NH')
--Third Second Data
create table #myThird (id int, city varchar(20),Sector varchar(2)) insert into #myThird values (33,'Walmart','PP') insert into #myThird values (20,'Ediosn','DD') select f.*,s.Sector from #myfirst f join #mySecond s on f.city = s.city /* idcitySector 500NewyorkMK 100EdiosnHH */
i have doubt on two things
1) How Can i compare the City names, by eliminating 'The ' at the beginning (if there is any in second tale city) between first and second
2) after comparing first and second if there is no match found in second them want to compare with third table values for those not found
--i tried below to solve first doubt, it is working but want to know any other wasys to do it
select f.*,s.Sector from #myfirst f join #mySecond s on replace (f.city, 'THE ','')= replace (s.city, 'THE ','')
--Expected results wull be
create table #ExpectResults (id int, city varchar(20),Sector varchar(2)) insert into #ExpectResults values (200,'Atlanta','JK') insert into #ExpectResults values (100,'Ediosn','HH') insert into #ExpectResults values (300,'Greenwoods','DF') insert into #ExpectResults values (500,'Newyork','MK') insert into #ExpectResults values (700, 'Walmart','PP') insert into #ExpectResults values (800, 'Madidar','')
I am trying to pivot data based on columns value in year column... but results are not showing up correctly. I want to see all columns after pivot.I want to Pivot based on year shown in the data but it can be dynamic as year can go for last 3 years
I am also using an inner join as i have two amount columns in my code and i want to show both amount columns for all displayed year.I am able to pivot but I need in output all the columns like this Id,MainDate, Year1,Year2,Year3(if any), AMT1 for YR1, AMT2 for Yr1, , AMT1 for YR2, AMT2 for Yr2, AMT1 for YR3, AMT2 for Yr3,
Here is some data:
-- CREATE TABLE [dbo].[TEMP]( --[FileType] [varchar](19) NOT NULL, --[dType] [char](2) NOT NULL, --[dVersion] [char](2) NOT NULL, --[Id] [char](25) NOT NULL, --[MainDate] [char](40) NULL,
I have a new SQL 2005 (SP2) Reporting Services server to which I've just upgraded and deployed some SSRS 2000 reports.
I have a subreport that contains a matrix with two groups. The report data seems to be inexplicably repeating the data for the first row in the group for all rows in the group. Example:
ID1 ID2 DisplayData
1 1 A
1 2 B
1 3 C
2 1 A
2 2 B
2 3 C
Parent group is on ID1, child group is on ID2, report would show:
1 1 A
2 A
3 A
2 1 A
2 A
3 A
Is this a matrix bug in 2005 SP2, or do I need to do something differently? I can no longer pull a comparison version from an SSRS 2000 server to verify, but I believe it was working as expected before...
I would like to distribute some data in SqlServer Express which only my application can read from.
My question is - is it possible to secure a database so that only a specified user would have read/write permissions. Even the sa acount should not have the permission to read or write to the database although it would retain the right to drop the database.
One option I believe is to encrypt the data but I would prefer not to incur the performance penalty associated with this.
I have a report running and I am attempting to assign role based security. I added a group to the site level security. The group I added contains child groups. It doesn't seem that report server is looking into the child groups to see if the logged in user is a member of the child group. Is there anyway to get this to work instead of adding all the groups directly? I suspect that report server is using cominterop and cominterop is not traversing the directory tree?
I need to create a query that will count new cases based on the create date(create_date) and criteria for the groups(The only way to distinguish between the 2 major groups mts and bnb is area!= 'bnb" because everything else is MTS). The sample report I need to create below shows how it needs to be counted weekly, for a 4 month period, for the groups under MTS and BNB. The totals and grand totals can be achieved in the report tool. I want to create variables for the new cases (mts_newcases_sales, mts_newcases_salesd, bnb_newcases_salesd etc)
Ex. MTS sales : (status = 'Calculated' OR status = 'REJECTED') and errorsource != 'marketing' and accountns is null and area != 'BNB'(everything else is MTS)
MTS salesd ; Credit >= '1001' and (status = 'REJECTEDV' or status = 'ACCEPTEDS') and errorsource != 'marketing' and accountnr is null
BNB creditr: Credit < 101 and (status = 'SUBMITTED' OR status = 'REJECTEDS' OR status = 'REJECTEDA' OR STATUS = 'ACCEPTEDC')
Large design flaw, I know, but we have a table with a varchar field which contains alpha - numeric values. I need to change just the numerics, which can be in an position on the field:
Sample data of the field: Rec1: Sally Morgan 201-555-1212 Rec2: 555-4040 John Smith Rec3: Jane Houstin 201-555-6452 ext1223
Desired result: Rec1: Sally Morgan 999-999-9999 Rec2: 999-9999 John Smith Rec3: Jane Houstin 999-999-9999 ext9999
There's a bunch of UDFs out there for selecting just the numerics, but I'm having trouble throwing it into a viable script for repeatable execution.
I want to show cumulative numbers, but don't know how to calculate them.
Here is an example of the source and the wanted result:
Source:
[Week] [Count] 1 15 2 5 3 6 4 10 (until 52)
Result:
[Week] [Count] 1 15 2 20 3 26 4 36
Is this possible, and how?
TestData:
USE TestDb /*SqlServer 2005*/ CREATE TABLE Test( [Week] [int] NOT NULL, [Count] [int] NOT NULL ) GO INSERT INTO Test ([Week], [Count]) VALUES (1, 15) INSERT INTO Test ([Week], [Count]) VALUES (2, 5) INSERT INTO Test ([Week], [Count]) VALUES (3, 6) INSERT INTO Test ([Week], [Count]) VALUES (4, 10)
When sizing products we use predefined size groups that the users can choose any or all of the sizes from. For example if i size group consisted of sizes (6,8,10) they could use all sizes (6,8,10) or just (6,8) or just (10) if required. Similarly, if a group consisted of (S,M,L,XL) they could choose to only buy (S,L). They cannot choose across groups, so would not be able to choose (6,S)
Once the required sizing is determined they then assign size mixes to the sizes to denote how much of the buy will be in that size. So for example if we had 3 sizes: (6,8,10) and they had the associated mixes (25%,25%,50%) that would mean we would buy 25% of size 6 and 50% of size 10. All size mixes must add up to 100% in total.
The users do analysis to determine what sizes they wish to buy and how much of it.
We also have a franchise portion of the business that have some predefined size mixes. They use the same base size groups as above, but the rule is that they can only use sizes that the particular product is being bought in.
So if the assigned franchise mix is S (50%), M (50%) and the main mix was S (100%) then the franchise mix would only be able to then have the S size.
We would then eliminate the sizes from the franchise mix and then to ensure that the franchise mix still adds to 100 we would then pro-rate up the franchise mix to give a new mix. To do this I divide one by the total the remaining size mixes to get a ratio and then multiple the mixes by this factor.
In the case above not be able to use the M size and would only use the S.This would be
-Total of remaining mixes, in this case only size S for simplicity 1 / 0.5 = 2
-multiple original mix by this factor 0.5 * 2 = 1
size S would now be 100% instead of 50%
The issue I'm having is that on occasion some of the totals are adding up to 100.01% because another one of the requirements is that it needs to be 4 decimal places (0.1015 would represent 10.15% in excel)
Here is a shortened version of the code with some test data:
I have data in a table Item_TB that I need to extract in a way that pulls out the distinct pax name and all the ticket numbers associated with the passenger per booking reference.
The data is:
Branch Folder ID Pax TktNo BookingRef HQ 123 1 Jim 4444 ABCDE HQ 123 2 Bob 5555 ABCDE HQ 123 3 Jim 6666 ABCDE HQ 123 4 Bob 7777 ABCDE HQ 124 1 Jenny 8888 FGHIJ HQ 124 2 Jenny 9999 FGHIJ HQ 124 3 Jenny 3333 FGHIJ
I somehow need to get a function to pull the data out for each booking ref like so
--BookingRef ABCDE Jim 4444/ 6666 Bob 5555 7777 --BookingRef FGHIJ Jenny 8888/ 9999/ 3333
I know I can get a simple function to return the all data, but I do not know how to only include the pax name once.
I have a table with score info for each group, and the table also contains historical data, I need to get the ranking for the current week and previous week, here is what I did and the result is apparently wrong:
select CurRank = row_number() OVER (ORDER BY cr.CurScore desc) , cr.group_name,cr.CurScore , lastWeek.PreRank, lastWeek.group_name,lastWeek.PreScore from (select group_name, Avg(case when datediff(day, asAtDate, getdate()) <= 7 then sumscore else 0 end) as CurScore
[Code] ....
The query consists two parts: from current week and previous week respectively. Each part returns correct result, the final merged result is wrong.

Have installed SQL Server 2008 R2 Express (includes SSMS tool) on Windows server 2008 R2 sp1 without any issues.Database created with no issues, full text catalog created via the wizard also with no issues but cannot run the process as a scheduled task of updating the catalog because the SQL agent is not available in the express version.
The full text index information is already being populated and updated by a third party application so this leaves just the catalog to be updated as and when new full text information is available.
I have a third party SQL scheduler which will run SQL scheduled tasks but requires a script to run the full text catalog update process
Is it possible to extract a script from the existing full text catalog to run the update process or how to create a script from scratch to do the same update catalog process in the third party scheduler?

May be we may do by dense_rank or Row_Number, but I couldn't get the exact query to produce based on the above table values. Â There are some duplicates in the table(which are not duplicates as per the Business). For those duplicated Unique ID should be same(Marked in Orange Color which are duplicates).Â
In this case I would like to output a single result for each order, but based on stock availability order 123 is not a complete order and 124 is so the results will need to reflect this.
I need to have a script where it ask the user for a value, the script will search for all records that match the value. Then it will display the numbers of records found and ask the user to enter a different value. The rest of the script will use this new value and increment by 1 n times as the number of records found. I started the script where it will ask for "HANDLE" and display the number of records found with that "HANDLE"
declare @HANDLE as varchar(30) declare @COUNT as varchar(10) declare @STARTINV as varchar(20)
set @HANDLE = ?C --This is the parameter to search for records with this value set @STARTINV = ?C --User will input the starting invoice number SELECT COUNT as OrderCount FROM SHIPHIST where HANDLE = @HANDLE
I just can't figure out how to proceed to use the entered invoice # and increment by 1 until it reach the number of records found.
This will be the end results:
Count=5 --results from query STARTINV=00010 --Value entered by user
The objective is to identify orders where an order fee has been applied incorrectly. I have multiple orders per customer, my table contains an orderID and a customerID. Currently if the customer places additional orders before the previous orders have been closed/cancelled, then additional fees are being applied.
Let's say I'm comparing order #1 to order #2. I need to identify these rows where the following is true:-
The CustID is the same.
Order #2 has a more recent order date.
Order #2 has a FeeDate Before the CancelledDate of Order #1 (or Order #1 has no cancellation date).
So in the table the orderID:2835692 of CustID: 24643 has a valid order fee. But all the subsequently placed orders have fees which were applied before the first order was cancelled and so I want to update the FeeInvalid column with a 'Y'. The first fee will always be valid.
I think I understand why the code I am trying doesn't achieve the result I want but I can't figure out how to write it correctly. Below is one example of code I've tried and also code to create the table and insert some test data.
update t1 SET FeeInvalid = 'Y' FROM MockData t1 Join MockData t2 on t1.CustID = t2.CustID WHERE t1.CustID = t2.CustID AND t2.OrderDate > t1.OrderDate AND t2.FeeDate > t1.CancelledDate CREATE TABLE [dbo].[MockData]( [OrderID] [float] NULL,
I am trying to code a rule at the moment which sets a value based on the value of the previous row. This is as far as I have got so far. I am trying to run it as a set based command and I believe I may need to make use of a numbers table.
Anyway the code is....
declare @data table (ID int identity(1,1), DeviceID int, EventTypeID int, EventID int)
[Code] ....
So the output is currently incorrect. Each DeviceID needs to have a ID assigned to the MIN(ID) which isn't yet in the code above. This ID has to be sequential across the full table and not dependent on ID.
Next the rule is coded in the case statement above.
So for each DeviceID, when the EventType goes from 1, 2 or 4, to 0 or 3, the following record after the 0 or 3 will have a new EventID. And conversely when the EventType goes from 0 or 3 to 1,2, or 4, the record that is the 1, 2 or 4 will have a new EventID.
