SELECTing Random Record From TABLE?

Apr 24, 2001

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.

Selecting Only The Last Record In Joined Table

Oct 10, 2005

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 :)

Random Record With TOP Parameter

Apr 19, 2004

I'm familiar with querying for a random record, however I can't seem to do it using a parameter driven TOP value.

Here's what I've tried in a stored procedure:
(
@Count int = 1
)
declare @sql varchar(1000)
set @sql = 'SELECT DISTINCT TOP ' + convert(varchar, @Count) + ' * FROM RandomisedView'


The view I am using looks like:

SELECT TOP 100 PERCENT dbo.TableName.* ORDER BY NEWID()

The stored procedure does not seem to cause the View to reorder the records.

I need to be able to select X random records. Any help would be appriciated.

Selecting The First Record In A Join?

Mar 1, 2012

I have one table like this:

Code:
CREATE TABLE DlIndexTable
(SessionStartTime DATETIME NOT NULL PRIMARY KEY, SchemaID INTEGER NOT NULL,
DLBaseRate REAL NOT NULL)

and one like so:

Code:
CREATE TABLE DlTextDataTable (
SessionStartTime DATETIME NOT NULL REFERENCES DlIndexTable,
ChTimestamp FLOAT NOT NULL, Channel01data VARCHAR (255),
Channel02data VARCHAR (255), ... , Channel16data VARCHAR (255),
CONSTRAINT TxtDatPriKey PRIMARY KEY (SessionStartTime, ChTimestamp))

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.

Selecting Top Record In A Group?

Mar 18, 2015

I’m writing a document management system. The documents themselves are created from the contents of a database. The database is SQL Server.

The database contains a table, like so:

ClientID, ProjectID, DocumentID, MinorVersion, MajorVersion, Name

Initially, the user will create a “V0.1” document. So the data would look something like

ClientID = 1
ProjectID = 1
DocumentID = 1
MajorVersion = 0
MinorVersion = 1
Name = “My Document”

Thereafter, the user can create new versions as “0.2”, “0.3”, etc., or “1.0”, “1.1”, “2.0”, etc.

For example, a “2.1” document would be stored as:

ClientID = 1
ProjectID = 1
DocumentID = 1
MajorVersion = 2
MinorVersion = 1
Name = “My Document”

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.

Selecting Only Earliest Record - Query Help

May 25, 2005

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. :)

Selecting The First Instance Of Each Record From A Subset

May 21, 2001

Hi

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:

1231999-06-14 12:17:11.000
1231999-06-14 12:17:31.310
1231999-06-14 12:17:31.000
1231999-06-14 12:22:56.000
1231999-06-14 12:22:58.000
8901999-06-15 10:00:18.000
8901999-06-15 10:03:30.340
8901999-06-15 10:03:30.000
8901999-06-15 10:03:40.000

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


Thanks in advance

Help Selecting Duplicate Record Details

Oct 10, 2006

I have the following query I am using to identify duplicate records in one of my database tables:


Code:


SELECT memberID,
COUNT(memberID) AS NumOccurrences
FROM ChapterMembers
GROUP BY memberID
HAVING ( COUNT(memberID) > 1 )



Executing the above proc returns 4079 records...

Now, I would also like to know the ChapterID for each member with a duplicate record. ChapterID is also stored in the ChapterMembers Table...

I tried running the following procedure:


Code:

SELECT memberID,
COUNT(memberID) AS NumOccurrences, chapterID
FROM ChapterMembers
GROUP BY memberID, chapterID
HAVING ( COUNT(memberID) > 1 )



But zero results are returned ...

The ultimate goal here is to identify duplicate records where one of their chapterID's = '81017' and to delete that record from the database.

Anyone have any ideas what I am doing wrong? Also, any suggestions for removing the records would be appreciated.

Thanks,

Jandrews

T-SQL (SS2K8) :: Selecting The Top Record With Certain Conditions?

May 14, 2014

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.

output of the query is

id_action id_resource actionKindCode
4665 4 clean
34540 96 pickup
24000 901 clean
declare @mytable table (
id_action int,
id_shift int,

T-SQL (SS2K8) :: Selecting Latest Record With Info

Aug 27, 2014

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.

Selecting Only 1 Record Based On Multiple Criteria

Jan 31, 2014

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:

Select h.worknumber, h.itemcode, h.descr, h.task_descr, h.qty, h.itemised,
h.serialnum, h.manufacturer, h.model_id, h.depot, h.date_in, h.date_approved,
h.est_complete_date, h.actual_complete_date, h.meterstart, h.meterstop,
h.custnum, h.name cust_name, h.addr1, h.addr2, h.town, h.county, h.postcode,
h.country_id, h.contact, h.sitename, h.siteaddr1, h.siteaddr2, h.sitetown,

[Code] ....

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.

Selecting A Top Record Based On A Datestamp Field

Jan 30, 2008



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

AND a.OrderID = b.OrderID
