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.
Is there a way to limit the number of rows returned by a SqlDataReader? I know I can do it by modifying the Stored Procedure, but I'd rather not modify a procedure that is used in multiple apps. I'm hoping there is something easy like setting SqlDataReader.RowsReturned = 100, but that might be too easy to hope for.
There may/may not be an upper limit for the number of rows in a table, but is there any performance-related limit?
I'm designing a database that stores results that have been acquired from a number of devices. Each device provides a set of data measurements every 10 minutes. Therefore each year a device will produce 52000 sets of results. If I design a table to store a row for each set of measurements from a device (PK is based on the timestamp and the deviceID), and if there are 100 devices recording for 5 years, there will be 52000x100x5 rows. Would I get a performance increase by separating this data into one table per year? Perhaps the year could be appended to the table name to identify the particular tables.
A secondary issue is some devices can also be configured to produce a different set of measurements every 10 seconds. In this case there will be hundreds of millions of rows over a 5 year period. Therefore I am considering bulking the results into an array for a 10 minute period, and storing this array as a blob each 10 minutes. Is this going to be faster or slower than having hundreds of millions of rows?
Hi, Here's my problem. I have an Area Chart, and I need to plot more than 300,000 records. Problem is RS cannot seem to handle this huge dataset. It would retrieve for 20mins, then after that it will just have an error "Internet Explorer cannot display the webpage". I am not encountering this if I just have a few records to plot. Please help
Hallo!I have small or big problem.I want creat Store Procedurs whit limit rows.For example I need rows from 100 to 200.--Select * from tableHow I doing best way.
Is there a limit of how many rows a table can have in SQL compact Edition? I didn't find anything in the documentation, but I get regularly a funny error message "Expression evaluation caused an overflow. [ Name of function (if known) = ]" when I try to create record number 32768 (is equal to 2 to the power of 15).
Hello SQL gurus!I am trying to write a query that will return a set of continguous rowsfrom a table, and limit the number of rows returned when a maximumtotal has been reached by adding a value in one of the columns.For example, the two columns below represent 2 columns in a table.a 2b 2c 2d 3e 4f 5g 5I want to start at, say "c", and return all the rows after it as longas the sum of the numbers in column 2 (starting at "c") don't exceed10. The result I'm after would be thusc 2d 3e 4....because 2 + 3 + 4 = 9 < 10Any ideas? Many thanks.
I get 100 rows of result, i want to write a sql query similar to the one available in MySql database where in i can specify the starting row and number of rows of records i want,
something like,
select * from emp LIMIT 10,20
I want all the records from the 10th row to the 20th row.
This would be helpful for me to do paging in the front end , where is i can navigate to the next previous buttons and fetch the corresponding records.
I want to do something like in google, previous next screens.
So I am trying to limit the number of rows fetched from a query.
somethin like,
select * from emp where startRowNum=10 and NoOfRecords = 20
Hi, I€™m trying to create a VERY wide table, with 1,000 columns of type varchar(MAX), nullable. The CREATE TABLE statement (both in SQL 2005 & 2008), gives the following warning:
Warning: The table "WIDE_TABLE" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit.
When I insert data into the table, filling all columns with small, 10-byte string values, I get the following error:
Msg 50000, Level 16, State 1, Procedure sp_pivot, Line 118
Cannot create a row of size 15034 which is greater than the allowable maximum of 8060.
I€™d like to verify this observation: each row is created with 2000 bytes of offset data (2 byte * 1000 columns), 125 bytes for null bitmap (1000 columns / 8 bits) and some more €śwasted€? row information. This leaves less than 6K for the data itself. But since not all columns can fit within the page, forwarding pointers in the row need to be created, 24 byte per column, which very quickly add up to more than 8K, thus the error. So the 8K limit is met for much less columns than the max 1024 column restriction.
Furthermore, in SQL 2008, SPARSE columns will not solve the problem (maybe save some €śmetadata€? space in case the columns are null, but if not, I€™m with the same problem again, or even worse, since now each value takes more storage space. The max 30,000 columns in 2008 is only for cases where the column values are really sparse€¦
Is this the right observation? if so, is there a workaround besides splitting to multiple tables?
I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.
The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.
Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.
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?
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'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.
JobRequirements (A) JobID int QualificationTypeID int
EmployeeQualifications (B) EmployeeID int QualificationTypeID int
Employee (C) EmployeeID int EmployeeName int
I need to return a list of all employees fit for a specific job ... The criteria is that only employees who have all the JobRequirements are returned. So if a job had 3 requirements and the employee had just 2 of those qualifications, they would not be returned. Likewise, the employee might have more qualifications than the job requires, but unless the employee has all the specific qualifications the job requires they are not included. If an employee has all the job qualifications plus they have extra qualifications then they should be returned...
How to only return those records where all the child records are present in the other table..
When creating a database, SQL Server 6.5 seems to have a 2 gig limit. What I mean is that if the device chosen is over 2 gigs SQL Server displays the size of the device as anegative number. This prevents me from being able to expand the database when I need to. Can anyone tell me why this is so, and if there`s anyway around it??
