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 having a mental block on a select statement.I have a table with the following columns:KitId int LotNo varchar(10) DateReceived smalldatetimeIt is possible to have many rows with the same LotNo but a differing DateReceived I need to write a select statement that returns the KitId for a given LotNo with the earliest DateReceivedso if I had rows:KitId =1, LotNo = 123, DateReceived = 11th May 2008KitId =2, LotNo = 123, DateReceived = 28th May 2008KitId =3, LotNo = 125, DateReceived = 28th May 2008KitId =4, LotNo = 127, DateReceived = 28th May 2008KitId =5, LotNo = 123, DateReceived = 12th June 2008I would want to retrieve KitId=1 if I provided LotNo 123 as a parameter Whilst it should always be the case that the LotNo with the earliest date will have the lowest KitId I cannot guarantee that will be the case so going for the lowest KitId isn't an optionCan one of you SQL gurus provide me with the statement I need?ThanksNeil
because the bankruptcy_date date are all equal i would need to pull one record with the earliest date from the doc_received_date. The date with the arrow is the record i want. So basically i would like to show this result
Hello all,Quick sql syntax question:I have this table:if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[REQUESTS]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)drop table [dbo].[REQUESTS]GOCREATE TABLE [dbo].[REQUESTS] ([ROW_ID] [uniqueidentifier] NULL ,[REQUEST_DATE] [datetime] NULL ,[STATUS] [tinyint] NULL) ON [PRIMARY]GOwith these values:insert into REQUESTS (REQUEST_DATE, STATUS)values (getdate(), 0)insert into REQUESTS (REQUEST_DATE, STATUS)values (getdate(), 1)insert into REQUESTS (REQUEST_DATE, STATUS)values (getdate(), 0)I need to select the single record with a STATUS = 0 with the earliestREQUEST_DATEI am using this query:SELECT TOP 1 ROW_ID FROM REQUEST_LOG WHERE STATUS = 0 ORDER BYREQUEST_DATEnot sure if this is the way to go...pointer appreciatedthanks
It is all contained in one table. I have got the earliest years by using the YEAR() function and grouping by it. The only problem is that I am having a problem joining the table back onto itself with the subselect because of it's an aggregate.
Here is the first join I have....
SELECT DT.ClientID, Year1 FROM ( SELECT ClientID, YEAR(MyDate) as Year1 FROM MyTable ) AS DT GROUP BY ClientID, Year1 ORDER BY ClientID, Year1
I want to use that as my derived table and then join back to it... but it's not working...
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.

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?
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.
Hello everyone, I have a query problem.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 aquery (in MS SQL Server) that would return the last title published by everyof 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 toget is all publishers, and only their last title, so I don't have more thanone line for the same publisher, and this line should contain publisherdetails and last title details.I tried using DISTINCT, but it works on a whole resultant row rather then acolumn, and since rows are all distnict (because they also contain columnsfrom titles) this didn't help me.What I can do is (in my application) first get a list of publishers, andthen loop through them selecting only the last title belonging to eachpublisher. I want to see if there is a way to accomplish the same thing withan SQL query (or maybe a stored procedure, view, or whatever). Anything ispossible, as long as it stays within SQL server and doesn't rely on theclient application.Of course, both 'publishers' and 'titles' tables have a primary key('publisherID', and 'titleID'), and 'titles' has a 'publisherID' columnwhich relates titles with publishers.Help :)
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 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
I have a database full of different types of leads some for company A some for company B and so on, each doing a different service. However the leads from B can be used for A and leads from A can be used for B, so I want to merge the data.
Example:
Phone Number Name Home Owner Credit Insurance 727-555-1234 Dave Thomas Yes B 727-555-1234 Dave Thomas Gieco
I would like the end result to be one record:
Phone Number Name Home Owner Credit Insurance 727-555-1234 Dave Thomas Yes B Gieco
Since these were imported into SQL they all have a unique ID, here are the current labels
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks, Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.

Hi,I have a table (SQL Server 2000) with several date columns in it, all ofwhich are individually NULLable, but in any one row, not all the dates canbe NULL.I want a query which ORDERs BY the earliest date it finds in each row. I'mguessing I have to do this in two steps:STEP 1Using a UDF, find the earliest date and stick it in a new calculatedcolumn "earliest date"STEP 2ORDER BY this UDF-created columnIf this is the right way to go about this, is there a simple SQL way ofdetermining which is the lowest of several dates? (ie of doing STEP 1).Or am I looking at this the wrong way, and missing an easy *one-step* way ofgetting what I want?TIA,JON
