I'll put it like this. There is a 'publishers' table, and there is a
'titles' table. Publishers publish titles (of course). Now I want to make a
query (in MS SQL Server) that would return the last title published by every
of the publishers. Quite clear situation. But I can't make it work.
If I use inner join (which I should, because I need data from both tables)
then I get a result showing all publishers and all titles. What I want to
get is all publishers, and only their last title, so I don't have more than
one line for the same publisher, and this line should contain publisher
details and last title details.
I tried using DISTINCT, but it works on a whole resultant row rather then a
column, and since rows are all distnict (because they also contain columns
from titles) this didn't help me.
What I can do is (in my application) first get a list of publishers, and
then loop through them selecting only the last title belonging to each
publisher. I want to see if there is a way to accomplish the same thing with
an SQL query (or maybe a stored procedure, view, or whatever). Anything is
possible, as long as it stays within SQL server and doesn't rely on the
client application.
Of course, both 'publishers' and 'titles' tables have a primary key
('publisherID', and 'titleID'), and 'titles' has a 'publisherID' column
which relates titles with publishers.
Hello. I need to select a random record from TABLE. It might look easy with using RAND() function, but the tricky part is that ID's which are the PRIMARY KEY, were assigned as a random number. So right now ID's in that TABLE look some thing like that: -18745, 45809, 129, -5890023, 487910943, -209, etc... If any one have any ideas please respond. Thanks in advance.
CREATE TABLE First_Table (id INTEGER IDENTITY(1,1) NOT NULL, titre VARCHAR(50) NOT NULL, annee INTEGER NOT NULL, idMES INTEGER, genre VARCHAR(20) NOT NULL, resume TEXT, codePays VARCHAR(4), CONSTRAINT PKFilm PRIMARY KEY (idFilm), FOREIGN KEY (idMES) REFERENCES Artiste, FOREIGN KEY (codePays) REFERENCES Pays);
I'ld like fill in this tables records inserting in the column id values I got in the one other table. In Oracle it is possible to do it using sourceTable.nextval where sourceTable is created as: CREATE SEQUENCE sourceTable; How can I do it in MS SQL or Transact-sql?
We have an archive table which keeps each instance of a sales order that was archived under a "Verion No" field. Each time the sales order is archived it is entered into the archive tables (Sales Header Archive, Sales Line Archive). What I am trying to do is write a query to return all sales orders but only the most recent archived version.
For example this table layout is similar to what I am working with. Version No, Order No and Customer No. are the keys between the Header and Line tables, Customer Name column in the output is from only the Sales Header Archive table
SALES LINE ARCHIVE TABLE Version No - Order No. - Customer No -----> (other columns) 1 s-5 1000
RESULTS OF JOINED TABLES Version No - Order No - Customer No - Customer Name ---> (other columns) 2 s-5 1000 Something, Inc. 1 s-6 2000 Acme 3 s-7 3000 Company, LLC 1 s-8 4000 Blah & Associates 2 s-9 2000 Acme
It should return the last Version No of each Sales order.
Does that make sense? It is something probably easy... But, I've spent two days using multiples and multiples of different ways, that just aren't working: I'm about to dropkick my server cabinet...
I am working on a model where I have a sales fact table. Each fact record has four different customer fields (ship- to, sold-to, payer, and bill-to customer). I have one customer dimension table that joins to the sales fact table four times (once for each of the customer fields above). When viewing the data in Excel, I would like to have four hierarchies (ship -to, sold-to, payer, and bill-to customer) within Customer.
Is there a way to build hierarchies within my Customer dimension based on the same Customer table? What I want is to view the data in Excel and see the Customer dimension. Within Customer, I want four hierarchies.
Hi i was wanting to know how to select a record in a gridview. I have a gridview with firsname and lastname. I currently have select command on it but don't want it. I want to be able to select first name or last name and have it take me to that record on the database.
I want to get some combined data from both tables, so right now I am joining them at the SessionStartTime column, which is a primary key in the first and a foreign key in the second table, something like this:
Code: SELECT DlIndexTable.SessionStartTime, DlTextDataTable.Channel01data FROM DlIndexTable LEFT JOIN DlTextDataTable ON DlIndexTable.SessionStartTime = DlTextDataTable.SessionStartTime WHERE DlIndexTable.SessionStartTime BETWEEN '2006-10-13 16:40:08.790' AND '2012-03-01 17:54:30.930' ORDER BY DlIndexTable.SessionStartTime, DlTextDataTable.ChTimestamp
The trouble is that this query, exactly as requested, gives me all the entries from the second table matching the first, while I really would like to pick just one row (preferably, the first chronologically - by ChTimestamp) so that the first column (SessionStartTime) has distinct entries in the resulting table. What would be the simplest way of doing that? Performance is not a big priority over simplicity since the first table could have only a few hundred rows (maybe a couple of thousand), while the second will be real tiny.
The earlier versions will still exist on the database, but the latest version will be 2.1.
There may be several different documents, with different DocumentID’s (e.g. DocumentID = “1”, DocumentID = “2”), etc., and each of these documents may have many versions.
I’m trying to write a query to display a list of documents showing ClientID, ProjectID, DocumentID, MinorVersion, MajorVersion, Name… but the list should only display the latest version of each document.
So, if the database contained the following records:
ClientID, ProjectID, DocumentID, MajorVersion, MinorVersion, Name 1,1,1,0,1,My Document 1,1,1,0,2,My Document 1,1,1,0,3,My Document 1,1,1,1,0,My Document 1,1,1,2,0,My Document 1,1,1,2,1,My Document 1,1,2,0,1,My Second Document 1,1,2,0,2,My Second Document 1,1,2,0,3,My Second Document
My query should return:
ClientID, ProjectID, DocumentID, MajorVersion, MinorVersion, Name 1,1,1,2,1,My Document 1,1,2,0,3,My Document
… where 2.1 is the latest version of Document 1 and 0.3 is the latest version of Document 2.how to do it.

This is my first post so I hope I'm doing it to the right forum. I need to compare a LastUpdated time to Start and End Time fields to get the "Due" Time for a given order. Can someone give me the correct SQL? (the example below should result in 6:00:00 AM "Due" time.) All are DATETIME fields. Thank you.

I'm no SQL whizz yet but I'm learning hard, and need to get some information from our DB rather urgently so have resorted to this fantastic forum, only I can't find what I'm looking for.
Basically I'm selecting a whole load of entries that have a (admission)date field after 2001, but I only want to return the Earliest (admission) for each (patients number).
Here is the script I have created to select all the data, but how can I limit the results to just the earliest (admission date) for each (patient).
SELECT Admission_Year, Admission_Month, Age_On_Admission, [Length of stay(continuing)], [Patient's Number], [Cons epis seq no], Sex, [Main Primary Pas Diag], [Date of Death], [Epi duration], [OP Code1], [Admission date], [Date of Death] - [Admission date] AS [days before death],[Intended Management] FROM dbo.Admissions WHERE (Admission_Year > 2001) AND (Age_On_Admission > '64') AND ([Intended Management] = 'inpatient') AND ([Date of Death] IS NULL)
I would really appreciate it if anyone can help with this, I'm sorry I can't really contribute to this forum as an SQL expert as .net is really my forte and I usually spend my time contributing to the asp.net forums. :)
I'm sure this is an easy problem but my brain is fried today...however how do I do the following:
I have a two column table. One is a key field where duplicates can arise and the other is a datetime field. So you might have some records looking like this:
OK, how do I get the top 1 of each key so that I get a subset of records looking like the following: 1231999-06-14 12:17:11.000 8901999-06-15 10:00:18.000
The situation is that we have resources (trucks) that perform shifts. Shifts consists of actions. A resource can perform multiple shifts.
For every resource we want to find the record that:
- Is 'younger' than the last realized action.
- Has actionkind pickup, deliver or clean
I have constructed a solution with CTE and row_number but I was curious if there would be other alternatives. The fact that I'm joining a CTE onto itself and subject the outcome to a partition makes me think there are sharper ways.
Note that the action id in the data below is also sorted but in practice this need not be the case. The sorting key is prevalent.
Good Morning,I have a person table with personID. I have a personRate table withpersonID, rateID, and effectiveDate.I need to select fields from personRate, but I want the fields from theproper record.I need the one child record that has the most current date of the largestrateID.For example a person may have many rate records. I need the record that hasthe most current date of the largest rateID they have. Does that makesense?I am making a view that has data from both tables. I need to display themost current rate info.Any ideas? TIA ~ CK
I have a table with almost a million rows, although it's quite slim with just ID, date, userID, JobID etc.
Now I want to the ability to add comments to some (probably less than 1%) of those lines.
The question is whether to create a separate comments table to join to it, or to create a comments field within the existing table? The comments field would obviously default to NULL, so wouldn't bloat the table unnecessarily if I add that field (right?), and would always be selected with the row from that table, so I'm leaning towards the latter alternative.
I have created the following SQL snippet that is a very simple mock-up illustrating the problem (I hope!) that I am facing:
-- create table if object_id('tempdb..#tmpdelnotes') is not null drop table #tmpdelnotes
create table #tmpdelnotes( DelNote int identity (1,1) , DelDate date not null, Item int not null, Customer int not null)
[code]...
What I need to retrieve is a unique list of item numbers with information about the latest (DelDate) delivery note. The "Clumsy workaround" works, but is not very pretty when doing multiple table joins. Is it really necessary to use a derived table for this kind of query? Window functions can only exist in the SELECT and ORDER BY clauses, which is understandable since the calculations take place (I would guess) after the aggregations in the HAVING clause.
I have inherited a query which currently returns multiple instances of each work order because of the joined tables. The code is here and I've detailed the criteria needed below but need the best way to accomplish this:
Each work order should only be returned once, and with the following additional criteria:
1. i.meter - this should return only the lowest number from that file.
2. sm.next_calendar_date - this should return only the most recent date out of those selected for the certificates on this piece of equipment
3. wh.meterstop as [Last Service Hours], wh.date_created as [Last Service] - this should return the number from wh.meterstop at the most recent wh.date_created for that piece of equipment.
Hi,I have a stored procedure that has to extract the child records forparticular parent records.The issue is that in some cases I do not want to extract all the childrecords only a certain number of them.Firstly I identify all the parent records that have the requird numberof child records and insert them into the result table.insert into t_AuditQualifiedNumberExtractDetails(BatchNumber,EntryRecordID,LN,AdditionalQualCritPassed)(select t1.BatchNumber,t1.EntryRecordID,t1.LN,t1.AdditionalQualCritPassedfrom(select BatchNumber,RecordType,EntryRecordID,LN,AdditionalQualCritPassedfrom t_AuditQualifiedNumberExtractDetails_Temp) as t1inner join(select BatchNumber,RecordType,EntryRecordID,Count(*) as AssignedNumbers,max(TotalNumbers) as TotalNumbersfrom t_AuditQualifiedNumberExtractDetails_Tempgroup by BatchNumber, RecordType, EntryRecordIDhaving count(*) = max(TotalNumbers)) as t2on t1.BatchNumber = t2.BatchNumberand t1.RecordType = t2.RecordTypeand t1.EntryRecordID = t2.EntryRecordID)then insert the remaining records into a temp table where the number ofrecords required does not equal the total number of child records, andthenloop through each record manipulating the ROWNUMBER to only selectthe number of child records needed.insert into @t_QualificationMismatchedAllocs([BatchNumber],[RecordType],[EntryRecordID],[AssignedNumbers],[TotalNumbers])(select BatchNumber,RecordType,EntryRecordID,Count(*) as AssignedNumbers,max(TotalNumbers) as TotalNumbersfrom t_AuditQualifiedNumberExtractDetails_Tempgroup by BatchNumber, RecordType, EntryRecordIDhaving count(*) <max(TotalNumbers))SELECT @QualificationMismatched_RowCnt = 1SELECT @MaxQualificationMismatched = (select count(*) from@t_QualificationMismatchedAllocs)while @QualificationMismatched_RowCnt <= @MaxQualificationMismatchedbegin--## Get Prize Draw to extract numbers forselect @RecordType = RecordType,@EntryRecordID = EntryRecordID,@AssignedNumbers = AssignedNumbers,@TotalNumbers = TotalNumbersfrom @t_QualificationMismatchedAllocswhere QualMismatchedAllocsRowNum = @QualificationMismatched_RowCntSET ROWCOUNT @TotalNumbersinsert into t_AuditQualifiedNumberExtractDetails(BatchNumber,EntryRecordID,LN,AdditionalQualCritPassed)(select BatchNumber,EntryRecordID,LN,AdditionalQualCritPassedfrom t_AuditQualifiedNumberExtractDetails_Tempwhere RecordType = @RecordTypeand EntryRecordID = @EntryRecordID)SET @QualificationMismatched_RowCnt =QualificationMismatched_RowCnt + 1SET ROWCOUNT 0endIs there a better methodology for doing this .....Is the use of a table variable here incorrect ?Should I be using a temporary table or indexed table if there are alarge number of parent records where the child records required doesnot match the total number of child records ?
This is a simple one, and I know that it has to be fairly common, but I just can't figure out an elegant way to do it. I have a table with the following fields: OrderID (FK, not unique) InstallationDate (Datetime) CreateDtTm (Datetime)
There is no PK or Unique ID on this table, though an combo of OrderID and CreateDtTm would ostensibly be a unique identifier.
For each OrderID, I need to pull the InstallationDate that was created most recently (based on CreateDtTm). Here's what I've got so far, and it works, but man is it ugly:
SELECT a.OrderID, InstallationDate
FROM ScheduleDateLog a
INNER JOIN
(SELECT OrderID, max(convert(varchar(10),CreateDtTm,102)+'||' +convert(varchar(10), InstallationDate,102)) as TopRecord
FROM ScheduleDateLog GROUP BY OrderID) as b
ON convert(varchar(10),CreateDtTm,102)+'||' +convert(varchar(10), InstallationDate,102)=b.TopRecord
Ok here goes. I have 3 tables, one holds case info, the 2nd holds possible outcome on the charges, and they're joined on a 3rd table (CaseOutComes). With me so far? Easy stuff, now for the hard part. Since there's a very common possiblitly that the Case has multiple charges, we need to track those, and therefore, display them on a datagrid or some other control. I want the user to be able to edit the info and have X number of dropdowns pertaining to how many ever charges are on the case. I can get the query to return the rows no sweat, but ...merging them into 1 record (1 row) with mutiple drops is seeming impossible -- I thought about using a placeholder and added the controls that way, but it was not in agreement with what I was trying to tell it . Any ideas on how to attack this?
I want to update the startdate column (for all rows) so that when period is 0 then the new value is a hardcoded value (say '01-Dec-2000') but for all other rows it takes the value in the enddate column for the row of the previous column (with the same freq)
ie the startdate column for period 1 takes the enddate value for period 0 and so on for a particular freq
create table #periods (period int , startdate datetime , [enddate] datetime , freq int) insert #periods ( period , startdate , enddate , freq) select 0 , '01-Jan-1900' , '31-Jan-2001' , 1 union all select 1 , '01-Jan-1900' , '28-Feb-2001' , 1 union all select 2 , '01-Jan-1900' , '31-Mar-2001' , 1 union all select 3 , '01-Jan-1900' , '30-Apr-2001' , 1 union all select 4 , '01-Jan-1900' , '31-May-2001' , 1 union all select 0 , '01-Jan-1900' , '31-Jan-2002' , 3 union all select 1 , '01-Jan-1900' , '28-Feb-2002' , 3 union all select 2 , '01-Jan-1900' , '31-Mar-2002' , 3 union all select 3 , '01-Jan-1900' , '30-Apr-2002' , 3 union all select 4 , '01-Jan-1900' , '31-May-2002' , 3
/* I know I need a case statement to test for column 0 and to join the table on itself and have put something together but it fails for column 0 and updates to NULL - I think it must be to do with the join ??
