Row Size Limitations Of SQL Server 2005
Aug 13, 2007
I've created a database design and I'm trying to figure out if it's workable or not. I have 2 tables in particular that are sparse (20 columns, but only a few have data - about 100 bytes/row) but will grow very large - to the tune of 700 million rows.
My question is whether or not there is a problem with SQL Server 2005 having 1.5+ billion rows of data even though it will likely only take up 100 gigs or so on disk. Anyone have experience in large numbers of rows like this? We're still doing testing as far determining how slow queries will get.
Thanks,
Craig

Hi,
I am currently using the SQL Server Express edition with the intention of upgrading to the full version in the future.
I know the size limitation on the Database is 4GB - however does this include the log file as well? Nothing I read says the log file is included however if anyone can give the definitive answer I would be grateful.
Also my log file maximum is set to 2GB what issues are there with reducing this to say 500MB? I assume SQL Server automatically drops the old log data to add new data when the maximum is reached.
Thanks for your help.

Hi all,
I am using OpenXML to put the XML records into SQL Server 2000. I want to know how big xml file can be inserted without significant problems in SQL Server 2000? Are there any limitations of OpenXML? I am using ntext as the holder for XML stream data.
Here is the stored procedure.
Code Block
CREATE PROCEDURE insertDInfo
(@OrderDoc ntext)
AS
DECLARE
@hDoc int
EXEC sp_xml_preparedocument
@hDoc output,
@OrderDoc
INSERT INTO [DInfo]
SELECT *
from OPENXML (@hDoc,'Data/Despatch',3)
with
(
[ID_Key] varchar(60) '@ID_Key',
DNumber varchar(50) '@DNumber',
PartNumber varchar (50) '@PartNumber',
Quantity real '@Quantity',
OrderNumber varchar (50) '@OrderNumber',
)
ORDER BY
DNumber
EXEC sp_xml_removedocument @hDoc
GO
Any suggestions???

I am stuck! and need help!
I have a problem I can't seem to find the solution with this aweful limitations on VARCHAR fields of 255.
Within a stored procedure called Store_Check, I need to dynamically build a string (@string) using VARCHAR(255) since the text datatype can't be used in a stored procedure.
So,this string is built according to whether the Store ID is NOT NULL. So if the StoreID is not null, I start building this string 'Exec Update_Store_Address @StoreID1, @address2'. There are 20 StoreID's passed into Store_Check. IF all 20 StoreID's are not NULL, the executed String greatly exceeds 255 because the string winds up looking like this
'Exec Update_Store_Address @StoreID1, @address1 Exec Update_Store_Address @StoreID2, @address2 Exec Update_Store_Address @StoreID3, @address3 Exec Update_Store_Address @StoreID4, @address4 Exec Update_Store_Address @StoreID5, @address5 Exec Update_Store_Address @StoreID6, @address6 etc. etc.'
I am not executing this string within the StoredCheck procedure. It needs to be passed as ONE string to a VB program and it gets executed by the VB program. Even if I create 4 local variables and concatenate them, it stops at the 255th character.
Also, a local varialbe of type TEXT cannot be declared within stored procedure.
What can I do? I am stuck!

Hi, I'm not sure if this is where I should post this, but I'm trying to find out what the limitations of SQL Server 2005 Developer Edition (DE) are. I've gone through the Microsoft SQL Server site and they have very little information about the developer edition.Is there a connection limit for DE like 2000 did?

Dear,
I'm building an ASP.NET application using C# language and SQL Server 2000. This application is dedicated to be hosted on a VIsta Machine.Unfortunately Vista does not supports SQL SERVER 2000 so i must migrate to the SQL SERVER 2005. Since the application is a small application, we couldn't afford buying an SQL SERVER 2005 License so i decided to use SQL SERVER 2005 Express Edition. But i would like to know exactly what are the Limitation on the Express Edition to see if it will work with my application or No. Please Can anyone refer any document that describes in details all the limitation of the Express Edition ??? Thanks a lot.

Hi,
Apologies for the generic subject heading but I have a client who at my suggestion has implemented a reporting solution using SSRS. However, we are now finding serious limitations with this solution, primarily regarding exporting matrix data to Excel. The major concern is that after exporting matrix data you cannot sort, filter or format properly as we cannot repeat the group data, merged cells is also another big problem.
They are now seriously looking at bringing in different technology to address these problems and I was wondering if anybody had any positive ideas, as to how I can provide a way forward and overcome our issues?
Can I easily add an add-in to the existing export options, does SQL 2008 offer any improvements, are there any 3rd party offerings out there?
Grateful for any advice.

I am trying to resize a database initial log file from 500M to 2M. I€™m using€?
ALTER DATABASE <DBNAME> MODIFY FILE ( NAME = <DBLOGFILENAME, SIZE = 2 ) "
And I'm getting "MODIFY FILE failed. Specified size is less than current size." I tried going into the database properties and setting the log file to 2M, but it doesn€™t keep the changes.
Any help with this process?

Hi all,I have recently implemented a SQL 2005 cluster using SQL 2005 Standardon Windows 2003 Enterprise edition.Both nodes have 4GB of RAM and according to the datasheet, SQL 2005Standard can support the OS maximum memory amount and Win2K3 EntEdition can support 64GB!However, in Enterprise Manager, if I go to the "Memory" tab of theinstance properties I can't increase the memory beyond 2147483647(which I assume is around 2GB).I don't have AWE enabled but am unsure as to the ramifications of this.Any advice anyone could provide would be greatly appreciated.Many thanks,Ian

Is there a document/technical article/white paper, basically, some information as to what can be exported into a particular format and what cannot be.
I have a report which is fine when exporting to Excel but doesnt export to XML or CSV. All I get in XML or CSV is just a heading. I am thinking, may be its not right to export that report into XML or CSV formats.
Has this happened to anybody before? Any advise is appreciated.

SQL Express Ed is limited to one CPU, what happens if the CPU is a dual core CPU? Does SQL Express care? Does it see a dual core as a single CPU?
As for memory, stupid question, SQL Express is limited to 1 GB RAM, if I run it on a server with say 4GB of ram packed into it, will it affect SQL Express' performance? Will SQL Express even run if there is more than 1GB available? Or will SQL Express simply ignore the extra RAM with no negative consequences?
Thanks,
Andy

I am looking for a doc (BOL, etc.) which enumerates things like limits on the number of columns which can be replicated, or limits on the size of the row. BOL covers this for 2000, but I can not find it in BOL 2005.

Okay, when will SRS 2005 support Office 2007 extensions.
I find it hard to believe that a service pack has not been releaseed to support Office 2007. If there is I apologize in advance for this message.
Info: Microsoft.ReportingServices.ReportProcessing.WrapperReportRenderingException: An error occurred during rendering of the report. ---> Microsoft.ReportingServices.ReportRendering.ReportRenderingException: An error occurred during rendering of the report. ---> System.Exception: Excel Rendering Extension : Number of rows in the Excel sheet exceeded the limit of 65536 rows.

Hi,
As SQL Server XE can run on one PC maximum, does it mean that it can't support multi users??? I mean could it be installed on one server and to be used by multiple users connected to server with their PCs?

HI Everyone,
I understand that there is a 4GB size limitation on SQL Server Express edition. right?
What I want to know is what if a database file created in SQL Express is hosted with SQL Server 2005 will the file still have the 4 GB size limitations?

I've been developing a vb app with sql server 2005 and had planned to use express as the client server so the db could be distributed with the app. After importing 21 csv text files, I realized that I have way too much data. My understanding is that sqlexpress can only work with max 4gb database.
The 21 csv files (total 925mb) brought the db size up to 1.5gb and I still have at least 250 more files to go. Obviously, I need a different approach. What are the size limitations of the non express version of sql server 2005? Any suggestions on the best approach for this type of situation?

I was looking around, and I found this info on SQL Server Express:The 4 GB database size limit applies only to data files and not to log
files. However, there are no limits to the number of databases that can be
attached to the server.Does this mean I can use several different databases in my website, like one separate db containing forum entries, and one with user details and related stuff?

We are primarily a DB2 and Oracle shop. There are movements towards SQL Server for smaller applications. We would like to know if anyone out there has shop standards in determining which database should go with what type of application. What we are looking for are possibly database sizes, number of concurrent users, hardware and software cost, network infrastructure, security, scalability, and development tools. Any information would be appreciated.

Hi all,I'm looking for some ball park estimates on when SQL Server might startto break down, and can't find any reliable info. Any insight is appreciated.Basically, the situation is this: The database structure is very simple;just one table with about 15 columns and about 60-75 million rows. There'sno need for massaging data or complex relations, just simple searches onmaybe a max of 5 columns. Out of the gates we'll be looking at having 30concurrent users and rapidly expanding to about 300-400 concurrent users.I might need to rebuild the database on a daily or weekly basisdepending on how often changes are made to a master file. In the past I'vebeen bit in the butt with the absolute crappiness of SQL Server'sreplication, so I'm going to try to avoid that path if I can (plus I alreadyhave some scripts written to delete and rebuild a similar database on anightly basis). Would it be practical to destroy and rebuild a database thissize on a daily basis?The big question is if searching 60-75 million records is practical inSQL server. If so, what kind of machine would I need to get a nearly instantresponse time per search (.2 second or so) when everyone's banging on it atonce? How many concurrent users can I expect to be able to practicallysupport before SQL Server will start to bog down? Thanks for your thoughts,-Ringo

Why is it, Microsoft manage to write operating systems and officeapplications with every bell and whistle facility known to man. Yet,even after years and years of development they still cannot produce adecent version of MS SQL Server, one without a plethora of flaws andlimitations? Personally I'd sack the MS SQL Server Chief Architect,start addressing some fundementals and do what MS do best - copy thebest functionality of their competitors.Here's a few reasons why I feel MS SQL Server is still a load of crap,and will never be many developers RDBMS of choice :1. Can't use domains in Multi-statement table-valued function tabledefinition2. No concept of table.column.datatype MYTABLE.MYCOLUMN%TYPE forfunction / proc parameters, variables. Schema evolution will requirechanges to dep functions / procs.3. Cannot call non extended user defined procedure from within storedproc - prevents code re-use4. No create or replace for functions / procs. Changes to procsrequire either a change from create to alter, or drop then create5. Functions must return result on final statement - requiresexcessive use of local variables. Why!!!???6. No user specifiable date format routines - must use convert withlimited options7. No treewalk mechanism, not easy to traverse hierarchical structure8. Calling procedures with out parameters require user to alsospecifiy which are out params9. Stored Proc recursion limitations to only 32 nested levels, ratherthan monitoring by stack size.10. No on delete set null referential integrity, this is fundementalin relational databases, has to be done by trigger. Yuk.11. No partitioning on db tables12. Cannot raiseerror in stored functions. No way to inform user ofincorrect parameters etc.13. No facility for sub - procs / funcs - for localised codenormalisation.14. No function overloading15. No concept of grouping similar procs / functions into a collectivepackage - can mean 1000s of procs rather than a handful of packages.16. Non standard func / proc calling - proc non parenthesised but,function defined and called with parenthesis17. Limited column name length in table variables / Multi-statementtable-valued function table definitions18. No intersect, minus operators to complement union and union all19. No exception handling - need I say more about this fundementalrequirement?20. No handling for select statements using proc parameters passed inas null e.g.create procedure sp_test.............select @MyID = IDfrom mytablewhere parent_id = @parent_id.If @parent_id is null, select will not return anything even if valuesfor null parent_id exist.21 No boolean type for use in stored procs / funcs. SQL standards doallow booleans (null, FALSE, TRUE)22 No repeat until - (post predicate loops), while loops can performthis but one extra check often has to be performed23 No equivalent to cursor or table %ROWTYPE, when fetching from amany column cursor, all bind variables have to be declaredindividually24. Declarative Delete cascade in SQL Server is at best rubbish - e.g.No table can appear more than once in the list of all cascadingreferential actions that result from the DELETE or UPDATE. Almost allother RDBMS I've tried seems to manage it.Create Table ForKey(MyID int not null identity primary key,MyText varchar(30))goCreate Table Refs(SomeID int not null primary key,RefID1 int not null foreign key references ForKey(MyID) on deletecascade,RefID2 int not null foreign key references ForKey(MyID) on deletecascade)Server: Msg 1785, Level 16, State 1, Line 2Introducing FOREIGN KEY constraint 'FK__Refs__RefID2__1BFD2C07' ontable 'Refs' may cause cycles or multiplecascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, ormodify other FOREIGN KEY constraints.Server: Msg 1750, Level 16, State 1, Line 2Could not create constraint. See previous errors.25. Domains cannot be altered without dropping all dependencies(stored procs / funcs) even if type isn't changed but say scale andprecision- this is ridiculous. What is the point of domains?26. No "for loop", while loops can perform this, but resultant code isnot as clear or tidy27. Can't use CURDATE() inside stored procs / funcs. How crap isthat?Don't try and make excuses for MS as I have hundreds, anyone else haveany?Jeager

Our Report Server DB almost doubled in size over the period of a week and is causing backup issues and using too much disk space.
We have over a hundred SQL 2005 DBs running in a portal on the same server as the Report Server all connecting to SSRS and many run their own Report Builder models and custom reports.
The table dbo.ServerParametersInstance is currently 3.6gb. I'm struggling to find any help in how to manage this in terms of reducing its size or what it is even used for.
Any help would me much appreciated.

Hello everybody
My office gave me assignment to find out the scope & limitations of the two Microsoft database applications - MS Access and MS SQL Server. After the findings, we have to chose the more appropriate database for our new project, which will have a humble start but may grow big in a year or two.
I will apreciate the info in facts & figures (not only in general).

I want to store a Zip file as a BLOB, but I get an error:
"File 'C:<path of mdf file> ' appears to have been truncated by the operating system. Expected size is 2560KB but actual size is 1536KB "
whenever the BLOB exceeds 1MB.
Any suggestions? How can I store larger .ZIP files to the Database?
I am using MS SQL 2005 Express and the data type that I gave for the column to store Blob is "varbinary(MAX)".
I am inserting byte array in to this field.
It works fine for a zip file less than 1MB but as soon as the zipped file size increases beyond 1MB, lots of error pop-up and then the database is not readable. Its says that, the data in the data base may have been corrupted...

We have a database that is backed up every night (full backup). The database size is around 5GB and the transaciton log is about 3GB. And it's 3GB after the backup too. I thought the log size should shrink after each full backup. I can't imagine what data the log needs to maintain after a full backup is complete.
What can be done about this large transaction log?
TIA,
