I have a query which can return multiple rows. I want to select only the nth row. In other db languages, this is achieved using the OFFSET command, but in SQL Server this command does not exist. I saw that you can hack it using ROWCOUNT and an ORDER BY clause, but I don't have anything to order by. Is there some other way to do this? My query is
Code:
SELECT S.SystemName FROM Projects AS P INNER JOIN ProjectSystems AS PS ON PS.ProjectId = P.ProjectId LEFT JOIN Systems AS S ON S.SystemId = PS.SystemID WHERE P.ProjectId = @ProjectID
What is the fastest way to select a value offset by n rows from the start row? I used to use a cursor with FETCH ABSOLUTE in Sybase SQLAnywhere, but this is incredibly slow in SQL Server. Here's the current function I'm using:
FUNCTION dbo.TradingDaysBack ( @ItemID int, @FromDate smalldatetime, @DaysBack int ) RETURNS smalldatetime AS BEGIN declare @BackDay int declare @OADay int set @OADay = dbo.GetOADate(@FromDate) declare curDaysBack cursor scroll for select OADate fromData_Daily whereItemID = @ItemID and OADate <= @OADay order byOADate desc
open curDaysBack fetch absolute @DaysBack from curDaysBack into@BackDay
close curDaysBack deallocate curDaysBack
if @BackDay is null begin set @BackDay= ( select Min(OADate) from Data_Daily where ItemID = @ItemID and OADate <= @OADay ) end
RETURN convert(smalldatetime, @BackDay)
END
The idea is to get the date n rows of data back from the starting date (i.e. 30 trading days back from 12/1/2003). Any ideas?
Please, please, please, please just add limit/offset to the language. 7 years of working around this unnecessary limitation are enough. And that's just me personally, i'm sure there are those out there with a longer history and are more irritated. I know this isn't the first post on this here, nor will it be the last. I think that should be taken as a hint, and something should be done about this. Something like this: SELECT column FROM table LIMIT 10 OFFSET 10
See, it wasn't that hard =) Now there are no ugly contortions to go through just to paginate the data. And don't recommend I return all 20k rows and do it on the client side, m'kay, or write ridiculous sql. It seems that for all the hard work that went into making those other features work that this could have been done. Don't lie, you know it could have! If there was a voting feature for suggested improvments, or a bug tracker + watch list that functioned the same, it would help. Others do that, as well.
//Another Annoyed DeveloperAnd seeing as there aren't any feature/suggestion channels that work (see:connect), I guess this forum is the best we can do. Sorry.
In MS SQL 2000, I would like to obtain the timezone offset from UTC fora given date. For today's date, I can doDATEDIFF(ss,GETDATE(),GETUTCDATE()). However, the offset for a futuredate may not be the same as today because some countries go in DaylightSaving mode. Can you suggest a way to obtain the timezone offset forany given date?ThanksYash
Sorry I have to post this here, but its sort of related to MS SQL anyway
I'm running a PHP system with MS Access. I need to order results in pages. (For those who are familiar with MySqL and Postgresql - I need the equivalent to LIMIT/OFFSET in MS Access).
I know I can "SELECT TOP 50" in my sql - so that solves the number of results per page. But what about page 2,3,4..etc.... how do I select results from an offset?
We recently translated the backend db from Access(97) to SQL Server.We are still using Access frontends. I have an update query in theAccess front end that uses a lookup table to populate fields. Thecommon fields between the table and the lookup table are the primarykey (LocID) and date & time fields. The query is:UPDATE tblPT_Offsets INNER JOIN tblPT ON tblPT_Offsets.LocID =tblPT.LocID SET tblPT.Offset_ft = [tblPT_Offsets].[Offset_ft],tblPT.Salinity = [tblPT_Offsets].[Salinity]WHERE (((tblPT.Offset_ft) Is Null) AND ((tblPT.Salinity) Is Null) AND((Format([Date]+[Time],"mm/dd/yy hh:nn")) Between [StartDate] And[EndDate]));This worked fine in Access and seemed to work fine after switching toAccess, but on closer look, there is exactly a 2 day error beingintroduced. A quick search of the newsgroups brings up lots of Accessto SQL date problems, but a 2 day offset seems rather strange? Anyideas??I know the field names Date and Time are inappropriate, but legacyissues are a pain in the butt to resolve!! Could this be a problem?David
I have the follwing function in my SQL data base which is hosted in Azure.
All date and time field in my db are store as UTC and I have a function define as below :
ALTER FUNCTION [dbo].[func_GetCurrentLocalTimeFromUTC] ( ) RETURNS datetime AS BEGIN DECLARE @OffSet as int = 1 DECLARE @CurrentDate as datetime = getUTCdate()
[Code] ...
Now what I have trying to do is to perform a select statement on a table where I have a dateTime value field and add the proper offset value to the field in order it is display based on where user will run the query. For example if I run this simple query :
SELECT INVENTORYDATE from Inventory
Will return the UTC dateTime value.
How can I use the select statement in order to get the field format with proper offset based on user pc timezone/. Please note that the query will be called from a rrs.
I have following simple code in my stored proc. even I have hard coded OFFSET to non zero, but it always return result from starting point 0. End limit "Fetch Next" is working perfect.Only problem is with start.
SELECT * FROM #invoices ORDER BY #invoices.InvoiceDateTime ASC OFFSET @StartRow ROWS Fetch NEXT @EndRow ROWS ONLY;
I'm getting a file that essentially has a parameter array: a specific like would have three known values, and then x number of groups of four parts;
The question is how to handle logical groups of parameters; i though maybe by using a modulous on their itemnumber ...
So I can easily use DelimitedSplit8K to definitively find the first thee values, but how do I dynamically get X number of groups of four; eventually i need the first three fields combined with each quadgroup.
So a rough example of the desired output is this:
this: '03,0000001,USD,010,81257946,,,015,121809761,,'is split into rows with the first three columns included in each row: 030000001USD01081257946NULLNULL 030000001USD015121809761NULLNULL
Here's a setup i've put together:
IF OBJECT_ID('tempdb.[dbo].[#AccountIdentifier]') IS NOT NULL DROP TABLE [dbo].[#AccountIdentifier] GO CREATE TABLE [dbo].[#AccountIdentifier] ( [AccountIdentifierID] INT IDENTITY(1,1) NOT NULL, [DateReceived] DATETIME NULL DEFAULT getdate(), [RecordCode] VARCHAR(3) NULL,
I've got a big problem that I'm trying to figure out: I have an address table out-of-which I am trying to select mailing addresses for companies UNLESS a mailing address doesn't exist; then I want to select the physical addresses for that company. If I get multiple mailing or physical addresses returned I only want the most recently edited out of those.
I don't need this for an individual ID select, I need it applied to every record from the table.
My address table has some columns that look like: [AddressID] [int] [LocationID] [int]
AddressID is a primary-key non-null column to the address table and the LocationID is a foreign key value from a seperate Companies table. So there will be multiple addresses to one LocationID, but each address will have it's own AddressID.
How can I do this efficiently with perfomance in mind???
I'm sure I am not undestanding some basic concept here but the following formula always produces an invalid token error at the '-' sign. In this example, I'm trying to subtract out a specific month from the total (this is a simplified example, my actual formula needs to compute a % change over time using lag...)
This produces the invalid token error (it always errors at the '-' in the equation)
with member [Measures].[MyCalcMeasure] as [Measures].[MyBaseMeasure]-([Date Submitted].[Date Submitted YQMD].[month].&[2008]&[1],[Measures].[MyBaseMeasure]) select [Measures].[MyCalcMeasure] on columns, [MyDim].[MyHierarchy].[Level1].members on rows from MyCube
But this works
with member [Measures].[MyCalcMeasure] as [Measures].[MyBaseMeasure] select [Measures].[MyCalcMeasure] on columns, [MyDim].[MyHierarchy].[Level1].members on rows from MyCube
As does this
with member [Measures].[MyCalcMeasure] as ([Date Submitted].[Date Submitted YQMD].[month].&[2008]&[1],[Measures].[MyBaseMeasure]) select [Measures].[MyCalcMeasure] on columns, [MyDim].[MyHierarchy].[Level1].members on rows from MyCube
When we try to run aggregation or purge queries on some tables we are getting following message:
" error [I/O error (bad page ID) detected during read at offset 0x000001ad65a000 in file 'E:MSSQL2KDataGenesys_DataMartGenesys_Datamart.mdf '. Severity 24, State 2, Procedure 'PWMGENESYSDB1 n u! ll', Line 1]"
After this we executed DBCC CHECKDB. Attaching the output obtained after executing this command, to fix these errors we executed DBCC repair_allow_data_loss. I am attaching output for this also. Pls go thru the logs and pls let me know what could be the problem and how it can be addressed.
A colleague of mine has a view that returns approx 100000 rows in about 60 seconds.
He wants to use the data returned from that view in an OLE DB Source component.
When he selects the view from the drop-down list of available tables then SSIS seems to hang without any data being returned (he waited for about 15 mins).
He then changed the OLE DB Source component to use a SQL statement and the SQL statement was: SELECT * FROM <viewname>
In this instance all the data was returned in approx 60 seconds (as expected).
This makes no sense. One would think that selecting a view from the drop-down and doing a SELECT *... from that view would be exactly the same. Evidently that isn't the case.

I'm trying to insert some values into an SQL Compact database on a WM6 device but there is something apparently wrong with my SQL statement...
The program is going to allow users to schedule an SMS message to be sent at a certain date and time. I'm using a database to keep track of the scheduled SMS messages. The database has 3 rows: phone number, message, and the date/time to be sent.
I'm guessing it doesn't like how I am trying to get the data from the different text boxes and the DateTimePicker to go inside the SQL command. Does anyone have any ideas on how to fix my SQL command or how to get data from a textbox and DateTimePicker to be inserted into a database a different way?
I am trying to select all entries from a database apart from the top/latest entry, via a stored procedure. Below is the code that i have but i am doing it wrong somehow.
Any ideas?
Thanks

Hello,I have a gridview bound to a sqldatasource control. I have an emptydatatemplate setup. In the selecting event, I make sure that an actual select has been performed (and not on null data); however, I have cancelselectonnullparameters set to true to stop it, because initially it will be null.However, the selecting event runs, even when I cancel it, the emptydatatemplate shows up. How do I prevent that from occuring?

Hi, This is quite an obvious problem, but for some reason I can't think through the solution. I have two columns, a datetime (datecreated) and an id (FK) othertableid (id)what I would like to be able to do is select a list of id and datecreated, but only chose the latest row for each id.So I guess it's a bit like a distinct on the id column, but ensuring the date returned is the top date. Please help
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.
hello all, i have a nested gridview. how do i add a SELECTING event for this datasource for my inner gridview? because i need to increase the commandtimeout. thnx. private SqlDataSource ChildDataSource(string strCustno) { string strQRY = "Select ..."; SqlDataSource dsTemp = new SqlDataSource(); dsTemp.ConnectionString = ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString ; dsTemp.SelectCommand = strQRY; return dsTemp; }
How can I select data between Mth row and Nth row from a specific search condition? for example , I want to get the 5th to 10th employee who is born in March and ordered by their name.
I have one table and it contains a column named ID Number, and a column named Date. I have a Do While statement that runs a SQL select statement a few times based on the number of records with the same ID Number. During the Do While statement the information is copied into another table and deleted from the old table. After I look at the results, I see that at the second Do While loop, the data was not selected and the Select statement did not run... so the old variable value from varValue is used again... Any reasons on why?
Here is a code snippet of what is going on: Do While varCount < varRecordCount conSqlConnect.Open() cmdSelect = New SqlCommand ("Select * From temp_records_1 where [id number]=@idnumber and date<@date", conSqlConnect) cmdSelect.Parameters.Add( "@accountnumber", "10000" ) cmdSelect.Parameters.Add( "@date", dtnow ) dtrdatareader = cmdSelect.ExecuteReader() While dtrdatareader.Read() If IsDbNull(dtrdatareader("value")) = false Then varValue = dtrdatareader("value") End If End While dtrdatareader.Close() conSqlConnect.Close()
'#####The information above is copied to another table here '#####The record where the information was received is deleted.
I have a tbale with maybe 30 columns and I'm selecting all where a record number matches a parameter I've passed. That works fine, however is there any way to do some conversions to fields when selecting without having to list out each column? For instance this is what it looks like now:
SELECT * FROM Losses WHERE @AppRecord = AppRecord ORDER BY Record ASC
But I want to convert say one column, is there a way to keep similar syntax instead of listing out each column?
SELECT *, CONVERT(varchar(15), [Losses]) as [Losses] FROM Losses WHERE @AppRecord = AppRecord ORDER BY Record ASC
And the column I'm converting is of type 'money'. I'm converting it to get rid of the extra zeroes at the end. If you know a better way to do it I'd be interested in knowing.

I have a content management system that I am building. My CMS has a pages table which contains 60 fields, some are varchars, some are ntext some are dates etc. They have field names which match their purpose like varchar1, ntext3 etc. These fields are used up depending on which template is applied to the page.
The templatefields table holds holds the information about each field in a template. It's control type (rich text control, date control etc) and the field in the pages table that the data will be stored in (varchar1,ntext3 etc)
What I want to be able to do is loop through the templatefeilds table for a particular template and then using the field name for the pages table, go to the pages table and get the value to populate the control.
So to clarify, I would like to produce a stored procedure which outputs the page field name (varchar1) from the templatefields table and varchar1's value in the pages table. Maybe in a temporary table.
Hi -- What is the proper way to select results with a date in the where statement when the datatype of the column is datetime? select * from table where date_field = '3-23-2006' does not get any results.
