SQL Server 2012 :: Query Pulling Latest Info Data From Table
Aug 29, 2014
Let's say I have a table of data as per the below..
I'm trying to extract only the green highlighted items..
The rules applied are: Only the latest data concerning all cases, and only 1 line (the latest) per case.
As you can see in the image, I don't want the 2nd,3rd, and 4th record extracted cause they are all superseded by more recent records (identified as they are further in the table).
I've considered using either Distinct or Having? but can't get that to work.. If I could use Distinct but then ensure it's the latest record in the table that would be perfect.
Chasis Status Date pl1 sold 10/20/2004 pl1 return 10/21/2004 pl2 sold 10/24/2004 pl2 return 10/25/2004 pl3 sold 11/01/2004 pl4 sold 11/03/2004 pl4 return 11/04/2004 pl4 sold 11/06/2004
sp i want to list out cars that status solid has been sold
so in this case only pl3 and pl4 can be display. So anyone can advise me on this. thanks
In our Microsoft Dynamics Nav instance we have a Sales Header Archive table - into which copies of the Sales Header are placed, with 3 items forming the compound key:
Document Number Version Occurrence number
so if doc 1 is archived, then the records would be
Doc# | Version | Occurrence # 1 | 1 | 1
When a second copy is archived a new record is added:
Doc# | Version | Occurrence # 1 | 1 | 1 1 | 1 | 2
and then when maybe a 3rd version is archived a 3rd entry added
This is for EACH document and I now need to retrieve the dataset which is the latest version of each document... but I'm drawing a blank!
If I
select [Doc#], max([Version]) as [V], max([Occurrence #]) from (table) group by [Doc#]
then I get the distinct list of docs, but I now need to use this list to select the records which match this criteria, from this table.
How do I select just these?
I thought (wrongly) that I could simply say:
Select * from Invoice Table where Invoice.[Doc#], Invoice.[V], Invoice.[Occurrence #] in (select [Doc#], max([Version]) as [V], max([Occurrence #]) from (table) group by [Doc#])
This is day 1 of me ever using RS so forgive ignorance of the topic.
Here's the basic scenario:
Input parameter from the user is an Account name.
For that account name I want to list Addresses of locations under the account, and then for each of those, I want to list received shipments from the address.
So Ideally the result is:
Account Name
Address 1
Shipment 1 Shipment 2 Shipment 3
Address 2
Shipment 1 Shipment 2
Address 3
Shipment 1
So, I am able to list the addresses just fine, but the next step is getting the stuff from the shipments table based on the currently running address? I'm probably saying that poorly. What I need to know is how do I structure the dataset/report to accomplish this. I suppose I could combine the query for the shipments with the query for the addresses, but that seems suboptimal to me.
I got this piece of code from one of your articles:
select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;DATABASE=c: est.xls', 'Select * from [Book1$]')
Question is, how can I use a fully qualified path for the xls file name if the file is located on the network elsewhere?is that possible with this option?
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.
Hey guys, I have created an asp.net page where users can select multiple items and then submit the form. I would like to return related items back. The catch is, I want to only return items that are related to all of the selected items. I've created a SQL Procedure that puts each of the inputted item's ItemId in to a temp table, I have a second table called RelatedItems which I use as my junction table that has ItemId, and ReleatedItemId, I then have my Item table that has the data I want to get to (I've excluded this because I have no trouble pulling out data once I have an ItemId) I can pull out all related ItemIds with a simple join, however I don't know where to start when it comes to pulling out only items related to all ItemIds in the @TempTable. Any help or suggestions would be great. Thanks, Matt
I need to do some advanced formatting in the text file, because the data in the text file is bit complex. I have some knowledge of using BCP, BULK INSERT and bit about FORMAT FILES but I want to do some advanced formatting(using IF condition and all) to pull the data from text file. Can anyone please tell me how can I perform bit advanced formatting using BULK INSERT?
I'm trying to find the most succinct way to get the last occurrence of April 1st given a date.
At the moment I'm using this:
DECLARE @Date DATE = '20131217' SELECT CONVERT(DATE, CAST(DATEPART(YEAR, IIF( --If we're at the start of a year --we'll need to go back a year DATEPART(MONTH, @Date) IN (1,2,3), DATEADD(YEAR, - 1, @Date), @Date )) AS VARCHAR(4)) + '0401')
I have a select query that results all the dbs and their several backup dates×. Howover I only need the latest backup dates for each of the db.How can I write that in tsql?
My query is pulling to many records becuase of the last join. This table can have multiple registration files for a computer. I just want the latest one or last one insert which is based on dttRegistration. I thought a top 1 select and order by would do it, but now returns no computer names.
I used to use this code to extract coupon usage from two tables orders and coupons
select distinct o.OrderDate, p.SKU, c.CustomerID, c.CustomerLevelID, c.Email, c.FirstName, c.LastName from customer c join dbo.Orders_ShoppingCart os with (NOLOCK) on os.CustomerID = c.CustomerID join dbo.Product p with (NOLOCK) on p.ProductID = os.ProductID join dbo.Orders o with (NOLOCK) on o.OrderNumber = os.OrderNumber
[code]....
Following a database upgrade the Coupon Code is no longer used. Instead there are two new SQL tables called Promotions and PromotionsUsage.. The link between the two tables are
ID in Promotions
and
PromotionID in PromotionUsage
Both are the same value. So in order to see new orders for coupon usage how would I change this line in the original SQL to retireve this?
I have two table, tblCharge and tblSentence, for each charge, there are one or more sentences, if I join the two tables together using ChargeID such as: select * from tblCharge c join tblSentence s on c.ChargeID=s.ChargeID , all the sentences for each charge are returned. There is a field called DateCreated in tblSentence, I only want the latest sentence for each charge returned, how can I do this? I tried to create a function to get the latest sentence for a chargeID like the following: select * from tblCharge c join tblSentence s on s.SentenceID=LatestSentenceID(c.ChargeID) but it runs very slow, any idea to improve it? thanks,
how do I get the variables in the cursor, set statement, to NOT update the temp table with the value of the variable ? I want it to pull a date, not the column name stored in the variable...
create table #temptable (columname varchar(150), columnheader varchar(150), earliestdate varchar(120), mostrecentdate varchar(120)) insert into #temptable SELECT ColumnName, headername, '', '' FROM eddsdbo.[ArtifactViewField] WHERE ItemListType = 'DateTime' AND ArtifactTypeID = 10 --column name declare @cname varchar(30)

HI All, I want to pull data from mysql dbms to sql servr 2005, i have wrote the following codes but it takes more than an hour and half which is not visible. Thus is there any consideration to consider and reduced time it takes. For your information i am going to use SSIS packags, there is no any tranformation, it is direct dump. Here is the code i am using,
SELECT * FROM OPENQUERY (Server_1,'
SELECT t3.Column11 as Column1, Column12 as Column2, Column13 as Column3, Column14 as Column4, Column15 as Column5, Column16 as Column6, Column17 as Column7, Column18/1000 as Column8 FROM table1 t1 INNER JOIN table2 t2 ON t1.ColumnId = t2.columnID INNER JOIN Table3 t3 ON t2.columnId = t3.columnID WHERE t1.Column4 > Sometime ')
To avoid locking/blocking, or in transaction scope, we are trying make a common practice of writing coide for update commands in our all SPs based on primary key columns in where clause. I have a following scenario...
UPDATE [dbo].[TL_CST_Locker_Issuance] SET [isActive] = 0 WHERE LockerIssuanceId IN (SELECT LockerIssuanceId
[Code] ...
What is the better approach and should be followed to avoid locks and gain performance or best approach.
I want to be able to see when records have been added to a table. The issue is we have a DTS job scheduled to run every night. The developer who wrote it password protected it and doesn't work here anymore. I want to add a step to this series of DTS jobs and want to run it just prior to his job. Is there a way to see when the records are being added or when this job is being run? Thanks again, you guys are the best.
What is the best way to transfer data from the staging table into the main table.
Example: Staging Table Name: TableA_satge (# of rows - millions) Main Table Name: TableA_main (# of rows - billions)
Note: Staging table may have some data same as the main table.
Currently I am doing: - Load data into staging table (TableA_stage) - Remove any duplication of rows from the staging table (TableA_stage) - Disable all indexes on main table (TableA_main) - Insert into main table (TableA_main) from staging table (TableA_stage) - Remove any duplication of rows from the main table using CTE (TableA_main) - Rebuild indexes on main_table (TableA_main)
The problem with the above method is that, it takes a lot of time and log file size grows very big.
I want to fetch below 3 records from the above scenario i.e. latest record of each amount (Latest is determined using "descr" column i.e. 4 is greater then 3 -

I have a table named 'DepartmentItem' which is designed with hierarchy structure. The column 'ParentId' from table DepartmentItem indicates parent-child relationship and department root among records. I have written and run a user-defined function I use recursive approach, but the function runs slowly.
My question: is there a better way to query that hierarchy table instead of using recursive?
** The current user-defined function that is written using recursive:
CREATE FUNCTION dbo.fnGetDepartmentTree ( @departmentItemId int ) RETURNS TABLE AS RETURN with DepartmentItemTree(DepartmentItemId , DepartmentItemTypeId , ParentId, ItemOrder, Level)
[code].....
** And definition of table 'DepartmentItem' :
DepartmentItemId int IDENTITY(1,1) NOT NULL, ParentId int NULL, -- Each department root starts when this column is NULL or the current row is department root. If it is not NULL then the current row has ParentId whose record has DepartmentItemId = ParentId of the current row (see more below) IsActive bit NOT NULL DEFAULT ((1)),
I'm trying to write some SQL which will give me the following result from the table below..
Currently I can do each of the PRICEx fields in a seperate query then join the results together. I do this by getting the MAX(Date) WHERE PRICEx IS NOT NULL then using that date to get PRICEx, and then repeat until I've done all the PRICE fields.
This is acceptable for a small selection, but for a large selection this can get quite slow. I was just wondering if there is there a way to do this in one single SQL without having to join the table to itself 3 times (for all 3 PRICE fields)
I'm trying to extract some data from an XML column, into the demo below I would like to obtain the CommandText value but my attempts so far are in vain, I'm fairly sure its just a path issue in the .query command but I just can't seem to get it to work.
I have query which is used to dynamically insert value but not working. We are trying to get all table names and insert dynamically to all tables by looping through table names.
declare @a varchar(max),@i int; declare @table table(rno int, name varchar(max)) declare @b varchar(max) insert into @table select row_number() over( order by table_name) rno, table_name from INFORMATION_SCHEMA.tables declare @tblname varchar(max)
I have a table (ScriptTable) which holds a groupID Nvarchar(10) ,SQLStatement Nvarchar (150)
Table Fields = GroupID SQLStatement 1234 Select CUSTNO, CUSTNAME,CUSTADDRESS from custtable where customerNo = 'AB123' 9876 Select CUSTNO, CUSTNAME,CUSTADDRESS from custtable where customerNo = 'XY*'
What I need is to take each select statement in turn and add the data into a temp table. I can use any method but it needs to be the most efficient. There can also be a varying number of select statements to run through each time my job is run.
I have a query currently that looks like this . @Month and @Year are supplied as parameters
SELECT -- select the sum for each year/month combination using a correlated subquery (each result from the main query causes another data retrieval operation to be run) (SELECT SUM(SalesofProductA) FROM #ABC WHERE [Year]=T.[Year] AND [Month]=T.[Month]) AS [Sum_SalesofProductA]
[Code] ...
Right now I see an output like this : for a particular value of @Month and @Year
SalesofProductA, SalesofProductB, SalesofProductC What I would like to see is :
