Is Being Over The 8080 Rowsize Limit A Big Problem
Dec 19, 2001
I have a SQL2000 database where the developers have a tool which creates screens and tables at the same time. During cleanup (dropping of some columns in these tables) I recieved the below error message
Warning: The table '%.*ls' has been created but its maximum row size (%d) exceeds the maximum numberof bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.
Apparently the tool is not sophisticated to recognize this problem. I looked at MS KB and it stated that inserts and updates may fail due to this. I probably know the answer to this, but has anyone else encountered this before, and what if any kind of problems did it cause. I am sure it is a no-brainer that this is asking for trouble, but if anybody has any experience with this issue all input appreciated.

I have a view that selects various fields, from various tbls. When I run that view it erros out as follows:
Could not insert a row larger than the page size into a hash table. Resubmit the query with the ROBUST PLAN hint. It seems like 1 particualr record, is exceeding the rowzise. and hence the errors.
Hi,I read this article on net recently.http://joseph.randomnetworks.com/archives/2005/08/30/sql-server-2000-maximum-row-size-8060-bytes/And according to it, SQL Server 2000 have around 8K of Row Size.Now consider this , i have table have two column and in each column i have inserted data around 6k.Now my question is , how sql server is going to store this.Is it in 2 different Row ?Can any one explains this or provides links related to it.ByeAmit
I get this mysterious error while running an update. SQLServer tells me that my update row is to big to fit in a row. Then I check the size of the row and and it is like 2000 bytes so it should fit without any problem at all. The really strange about it that when comments a field it works just fine. That field is always null. Could that be the problem. Anyone who have ever had a similar problem or so?
I have a select statment that gives me an error, cannot go more than rowsize 8094. I am trying to find the particualr record/acctno, where the rowsize is excedding the max limi of 8094 chars. Once I have the acctno, I will correct it. But how do I find which acct has this issue? Bascailly how can I find which record size is more than 8094 chars?
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??
we all know mysql: select * from table limit ?1, ?2
equals
sqlserver: SELECT TOP ?2 * FROM table WHERE (IDENTITYCOL NOT IN (SELECT TOP ?1 IDENTITYCOL FROM table order by IDENTITYCOL)) order by IDENTITYCOL
but the below SQL in mysql,how to convert?I enmesh........... select pageid,pagename,pageaddr,pageauditflag,pageartaudi tflag,startplaytime from pageinfo where entryid= ?1 and startplaytime= ?2 limit ?3, ?4
hi,I have a question.Maybe You know the equivalent to command LIMIT from MySQLI couldn`t find something like this in MS SQLPSI try to display 10 records begining form e.g. 4 sort by idsomething like: "SELECT * FROM table WHERE name=... LIMIT 4, 10 ORDER BY id"in MySQLthanx,Urban
I recently read up and found an msdn forum post that said the 4gb limit only applied to data files not log files.
However recently i had an error on a sql express database saying that the log file was full, the database log file was set to auto grow and there was plenty of space left.
So i am guessing the 4gb limit applies to any database file mdf or ldf, is this correct ?
I have the fields in my table: ID, Title, Description, Price, ImageData, Active I only want it to be possible to have two records at any time with Active=Yes. Active is a Bit, Yes/No, field. Any help is appreciated. Chuck
hi,i have a union statement that works like a charm:SELECT [Name], [EventID] AS [ItemID], [TourID], [Date], NULL AS [StartDate], [Date] AS [SortDate], [Type] FROM [Events] WHERE [TourID] IS NULL AND AccessLevel <= @AuthenticationLevel
UNION
SELECT [Name], [TourID] AS [ItemID], [TourID], NULL AS [Date], [StartDate], [StartDate] AS [SortDate], '2' AS [Type] FROM [Tours] WHERE AccessLevel <= @AuthenticationLevel
ORDER BY [SortDate] this statement selects all the records i want from both tables, and orders the entire new table by sort date.what i want to do is to add a limitation on the number of records. i have tried using both LIMIT and TOP commands, but i can't get it working. both of the below statements give me a syntax error saying "Incorrect syntax near the keyword 'ORDER'"first try:SELECT * FROM (<same_statement_as_above>) ORDER BY [SortDate] LIMIT 2second try:SELECT TOP 2 * FROM (<same_statement_as_above>) ORDER BY [SortDate]what am i doing wrong, and how do i achieve what i want?i am working with mssql server 2005 (express locally, and standard on my hosting service). thanks for your help!
I have an application with a DAL that has an interface with SQL Server. The application has 400 users that open the web forms. My question is: Is there a limit of the parallel connections that can be opened? Or the IIS is managing all the access to the DB? Should I worry about the performance Or it's normal behaviour for ASP.NET applications?
SQL takes all CPU resource on some of the intensive queries. Is any way to make sure there is something left for other tasks to be processed? Let's say limit SQL to use no more than 80% of CPU.
There is at present (as we accidently found) limitation of MSSQL to return per row maximally 8060 bytes. Message like this comes: "Cannot create a row of size 8279 which is greater than the allowable maximum of 8060". My questions are : - Is there any way how to pass it? If I split into more tables (as I have it now) and ask for result where these tables are connected over any ID the result is the same. If I use stored procedures it seems to be ok. Any other idea? - Will be this ok in SQL server 2005?
I have an application that uses a small SQL Server database. What I need is to prevent the access of an amount of users to the database. At the beginning I want to limit the access only for 2 users but I want to be able in the future to grant the access to more.
MySQL has a convenient syntax for paging data that looks like this: SELECT * FROM MyTable LIMIT 10, 20 That would select 10 records, starting from record 20, so that it returns records 20 - 30. This is convenient way to page data, without returning anymore rows than than you need.
However, MS SQL doesn't appear to support that syntax. What is the equivalent sql code to select any N rows from an arbitrary starting point, without having to create a stored procedure?
Quick question, is there a record limit in MSSQL assuming that we don't use a identity key. I am going to be using a table to sava mail server logs. It will create about 5000 records a minute. Also are there any perfomrance issues once you reach a certain numberof records, assuiming i am indexing one of the columns.
I have a extremely large table and out of that I just need 2 records but based on some logic . For example
IF EMPLOYEE_ADDRESS <> NULL set Employee_HAS_HOME to 1 ELSE set Employee_HAS_HOME to 0
Here I can not use just first 1000 records as I am not sure If I will cover the second condition in first 1000 rows . Then I came up with solution like : -
select * from employee_table where employee_address <> NULL LIMIT 1 UNION select * from employee_table where employee_address = NULL LIMIT 1
And this will give me 2 records which I can use for my testing . But unfortunately this is not working.
Hi, I am working on building SSIS Packages which will need to extract records from OLTP Servers, and i am half way through building the package, i wanted to test if it is able to extract the records from a particular table on OLTP....basicall i want to test if the package built so far running good?....but the extraction part takes ages as there are millions of records in the OLTP ...i want to limit those records to say some thousands so that i can test it and work on cleaning part in the staging and later after all the chunks are working perfectly i want to set it completely to run for extracting all the millions of records.
I am working on a report split into 2 Excel spreadsheets because it is roughtly 350 columns wide. I know this exceeds the MS Access column limit, but is there a way to build this in a single table in SQL Server? If not, does anyone have any ideas.
I have a table tblclients where all my client information is. In my application, I can assign a client to a therapist which is simply inserting the client id (intclientId) into the table with the inttherapistId and the authorid was completed the transaction. because we want to know the history of the transfers, I have to have a separate table other wise I could have just crated a field in the client table for the therapist id.
Simply enough.
The problem is when I assign the client to a therapist more than once, on the client log (the screen that shows all my clients) the client appears twice- once for each therapist he has been assigned to. I only want the client to appear once- and show the name of the latest therapist he has been assigned to not all the therapist. The way I did the select was to do an left outer join on the tbltransfer based on the client id. Works but like I said it gives me the client twice, if I assign them to the therapist more than once. So here is my statement:
select c.strfirstname, c.strlastname, c.intlocationId from tblclients c left outer tbltransfer t on t.intclientId = c.intclientId
this works, but if I have more than one record for the same client in the tbltranfer (if I assign the client more than once) then the recordset that is returned contains two records- one for each therapist assigned and that my problem.
I'm storing time series data in a table in SQL server 2000. The tablehas columns like: CodeEquity, PriceDate, LastPrice. To extract thelast price for a number of equities on COMMON DATES I have used thequery:select t.LastPrice,h1.LastPrice,h2.LastPrice,h3.LastPrice fromBlg_HistoricData t,Blg_HistoricData h1,Blg_HistoricDatah2,Blg_HistoricData h3where t.CodeEquity=114151 and h1.CodeEquity=112220 andt.PriceDate=h1.PriceDate and h2.CodeEquity=112580 andt.PriceDate=h2.PriceDate and h3.CodeEquity=112228 andt.PriceDate=h3.PriceDatethis works for about 20 self joined tables and then says syntax error.I'm wondering what sql limits it hits. Is it possible to do this inSQL for 300 tables?Thank you.
Hi, guys!Some of my applications are sharing same SQL login/password to connectto a database called "MyDB" on server "MyServer" . The password isencrypted and stored in registry or some configuration file theapplications use. The applications use certain arithmetic to decryptthe password and then connect to MyDB.The problem is a few developers know the arithmetic. So virtuallythere is no security here.I am wondering whether I can do anything on the MyServer/MyDB to limitthe access to the database so that only connection from certainservers are allowed. Say I only want connection with this knowncredential to be established if it is from server "Mybox". Noconnections from any other servers will be allowed. So even thedevelopers know the login/password, they won't be able to do anythingif they do have the access to server "MyBox".(I know some of you would ask why I don't use application roles. Let'ssay it's due to "historical" reasons and it's not totally up to me tochange the way the developers use database.)Any idea? Triggers in Master? Not a good idea, isn't it?Thanks in advance,Gary
Does anyone know if there is a way to limit certain users/logins to only use 1 CPU on a box with 4 processors? I need to somehow restrict CPU utilization for a user and I'm wondering if this can even be done in SQL Server 2005. Any help would be appreciated.
