Varchar(max) And Off-row Storage

Jun 20, 2007

From what I've read, if a row contains more than 8060 bytes and has varchar(MAX) columns in it, the data in those varchar(MAX) columns will be stored off-row. But what happens if you have two varchar(8000) columns instead and both contain more than 4030 bytes, is the data for both stored off-row? If so, just for that row, or for all rows in that table? And is there ever a good reason to have two varchar(8000) columns in a SQL Server 2005 table, instead of using varchar(MAX)?

SQL Server 2012 :: Storage Of VARCHAR (MAX) When Null

May 7, 2014

If I have a table

CREATE TABLE [dbo].[logg](
[Id] [bigint] IDENTITY(1,1) NOT NULL,
[Details] [varchar](MAX) NULL)

insert logg (Details) values('')
insert logg (Details) values(null)

Will both statements above access only a single page (as it fits into one page) or does the VARCHAR(MAX) always put its data on a separate page. If so, is the null insert treated differently from the '' insert?

SQL 2012 :: Distinct Storage Tier Of Remote BLOB Storage (RBS)

Oct 27, 2014

How to implement distinct storage tiers on SQL Remote BLOB Storage (RBS)?

I want to use this SQL Feature to move files(images, videos, pdf files) from a database to a distinct database dedicated to RBS. Then I want to have several storage tiers, where objects will be saved and moved according access frequency. Old data will be arquived in cheap storage, but it must be always accessible if needed.

Description:
- 1st and main tier: new and frequently accessed objects stored in high performance storage;
- 2nd tier: automatically move older or less accessed objects to an inexpensive and different storage tier;
- in all cases, all objects must be accessible to all users, but accessing to archived objects(2nd tier) will be much slower;

Can't Install IBM Tivoli Storage Manager Server On Windows 2003 X64 Storage Server, How Can I Fix The Pkg?

Jan 14, 2008

I am a Windows developer for the IBM Tivoli Storage Manager Server (TSMS) product.
Our product installation is built with InstallShield and uses the Windows Installer.

On a new installation of Windows 2003 x64 Storage Server R2, at a customer's site, the TSMS product fails to install.
The install of the OS has version 3.01.400.3959 of the Windows Installer and I see no newer version that installs.

Part of our product is 32 bit (console) and another part is x64 (server).
When installing I can see that the install's default is being redirected/reset to C:Program Files (x86)TivoliTSM after it is explicitly set by a custom action to ..Program Files.. . I further observe that our custom actions to write 64 bit registry entries are being refused.

REGSAM samMask = KEY_ALL_ACCESS;
if ( regIsWow64Process () ) samMask = samMask | KEY_WOW64_64KEY;
lStatus = RegCreateKeyEx( hLocalConnectKeyRoot,
szSubkey,
0L,
NULL,
REG_OPTION_NON_VOLATILE,
samMask,
NULL,
hKey,
&dw ) ;
The above fails to create the key.

We have tried four versions of our TSMS spanning many changes but the install acts the same.
This does not happen on any other Windows OS we test on but we do not test on Windows 2003 Storage Server R2 being that it is an OEM product. We did test on Windows server 2003 R2 x64 and do not see this problem.

Do you have any suggestions on how to tackle this problem?
I have full installation traces but can only see that the registry work is being refused. I can't see why.

Problems Moving Data Over 8000k In DB2 Varchar Column Into SQL Server Varchar(max) Using SSIS

Nov 20, 2007

I have looked far and wide and have not found anything that works to allow me to resolve this issue.

I am moving data from DB2 using the MS OLEDB Provider for DB2. The OLEDB source sees the column of data as DT_TEXT. I setup a destination to SQL Server 2005 and everything looks good until I try and run the package.

I get the error:
[OLE DB Source [277]] Error: An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available. Source: "Microsoft DB2 OLE DB Provider" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".

[OLE DB Source [277]] Error: Failed to retrieve long data for column "LIST_DATA_RCVD".

[OLE DB Source [277]] Error: There was an error with output column "LIST_DATA_RCVD" (324) on output "OLE DB Source Output" (287). The column status returned was: "DBSTATUS_UNAVAILABLE".

[OLE DB Source [277]] Error: The "output column "LIST_DATA_RCVD" (324)" failed because error code 0xC0209071 occurred, and the error row disposition on "output column "LIST_DATA_RCVD" (324)" specifies failure on error. An error occurred on the specified object of the specified component.

[DTS.Pipeline] Error: The PrimeOutput method on component "OLE DB Source" (277) returned error code 0xC0209029. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.

Any suggestions on how I can get the large string data in the varchar column in DB2 into the varchar(max) column in SQL Server 2005?

The Data Types Varchar And Varchar Are Incompatible In The Modulo Operator

Jan 4, 2008

I am trying to create a store procedure inside of SQL Management Studio console and I kept getting errors. Here's my store procedure.

Code Block
CREATE PROCEDURE [dbo].[sqlOutlookSearch]
-- Add the parameters for the stored procedure here
@OLIssueID int = NULL,
@searchString varchar(1000) = NULL
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
IF @OLIssueID <> 11111
SELECT * FROM [OLissue], [Outlook]
WHERE [OLissue].[issueID] = @OLIssueID AND [OLissue].[issueID] = [Outlook].[issueID] AND [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
ELSE
SELECT * FROM [Outlook]
WHERE [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
END

And the error I kept getting is:

Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 18

The data types varchar and varchar are incompatible in the modulo operator.

Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 21

The data types varchar and varchar are incompatible in the modulo operator.

Any help is appreciated.

SSIS - Importing Varchar From Access Into SQL2005 As Varchar

Nov 20, 2006

For the life of me I cannot figure out why SSIS will not convert varchar data. instead of using the table to table method, I wrote a SQL query so that I could transform the datatype ntext to varchar 512 understanding that natively MS is going towards all Unicode applications.

The source fields from Access are int, int, int and varchar(512). The same is true of the destination within SQL Server 2005. the field 'Answer' is the varchar field in question....

I get the following error

Validating (Error)

Messages

Error 0xc02020f6: Data Flow Task: Column "Answer" cannot convert between unicode and non-unicode string data types.
(SQL Server Import and Export Wizard)

Error 0xc004706b: Data Flow Task: "component "Destination - Query" (28)" failed validation and returned validation status "VS_ISBROKEN".
(SQL Server Import and Export Wizard)

Error 0xc004700c: Data Flow Task: One or more component failed validation.
(SQL Server Import and Export Wizard)

Error 0xc0024107: Data Flow Task: There were errors during task validation.
(SQL Server Import and Export Wizard)

DTS used to be a very strong tool but a simple import such as this is causing me extreme grief and wondering of SQL2005 is ready for primetime. FYI SP1 is installed. I am running this from a workstation and not on the server if that makes a difference...

Any help would be appreciated.

Datatype Question Varchar(max), Varchar(250), Or Char(250)

Oct 18, 2007

I have a table that contains a lot of demographic information. The data is usually small (<20 chars) but ocassionally needs to handle large values (250 chars). Right now its set up for varchar(max) and I don't think I want to do this.

How does varchar(max) store info differently from varchar(250)? Either way doesn't it have to hold the container information? So the word "Crackers" have 8 characters to it and information sayings its 8 characters long in both cases. This meaning its taking up same amount of space?

Also my concern will be running queries off of it, does a varchar(max) choke up queries because the fields cannot be properly analyzed? Is varchar(250) any better?

Should I just go with char(250) and watch my db size explode?

Usually the data that is 250 characters contain a lot of blank space that is removed using a SPROC so its not usually 250 characters for long.

Any insight to this would be appreciated.

Document Storage

Dec 23, 2003

Hello Everyone and thanks for your help in advance. I am developing a document storage application for an intranet that will store various Word, Excel, and PDF documents. Most of the examples I see utilize SQL Server and an image field rather than the FileSystem Object to store documents. My concern with this method is that some of the documents may be several hundred pages (not exactly sure of the actual file size yet, but they must be fairly large). My question is, where does the use of SQL Server become impractical for this type of application? Any insight would be greatly appreciated. Thanks.

Storage Strategy

May 30, 2006

Hi guys.

I am currently developing a system thats stores exchange stats in a db. Since our customers are companies with 20 employees up to 5 000 there a a big difference in the volume of data needed to be stored.

We currently thinking of supplying a SQL Server Express DB to the small customers and suggest a SQL Server to the bigger.

But since I would like to use the same structure for both types of customers I wonder how should i design the storeage.

Since the could be from 500 records a day up to 20 000. There are quite simple recordes with only simple datatypes. about 15 fields with no more than 10 chars each, mostly 2.

Should i separate the data in diffrent tables for a week or a day etc.
Since I am only going to filter data on 1 or 2 fields the data will be easly indexed.

The reports generated will almost always only use 1-3 months of data, but historical reports have to be possible.

My question are ofcourse:
Whats the best solution for me?

Thanks in advance:)

Image Storage

Jun 19, 2007

I have recently designed and built my first database using SQL server 2005 express. I have included an image (BLOB) column in one of the database tables. This is a bad idea according to some experts, and some say it is OK!

I am currently carrying out a trial with just 3 pictures via Visual Basic 2005 express forms, and there is no problem so far as the images are displayed for each record. But I anticipate between 300 - 1000 images for the table, and this could pose real problems for SQL server 2005 express and Visual Basic 2005 express, I guess.

I have just been reading that the cost of storing large images in the database is too high! I have also read it's better to store images (BLOB) into the file system because it is cheaper to store them no matter how many there are.

But the question is how I can reference an image in this path: C:PictureProductGrocery0052745.jpg in the database table, so that when I select a record Visual Basic 2005 forms the image is displayed accordingly, similar as when stored directly in the database table? Your help very much appreciated.

Maximun Storage

Mar 25, 2008

Hi All
from following link
http://msdn2.microsoft.com/en-us/library/ms143432.aspx
i got this information

Bytes per row
8,060
Bytes per varchar(max), varbinary(max), xml, text, or image column
2^31-1
Characters per ntext or nvarchar(max) column
2^30-1

so is it means we can store in nvarchar(max) or varchar(max) upto 2^31-1 characters/bytes. but on the other hand we can store only 8060 bytes in a row. so the concept of Row-Overflow Data Exceeding 8 KB comes into picture.
my questions is suppose i declare a variable of type varchar(max) then i can store upto 2^30-1 bytes in it and SQL Server on its own determine how and where to stores it.

Volatile Storage

Feb 16, 2007

I am new to windows mobile development, and I am looking to create an application (C#) which uses the SQL server CE. I am curious what to do about data loss. I have a Windows Mobile 2003 PDA, which means half of my storage is main memory (volatile) and the other is built in storage (no volatile).

I expect I would want to install my application to the main memory, along with the database. I Planned to give the user the abililty to select a subset of properties for running the application and storing them in the DB for running. But if the user's battery runs out I wouldn't want them to loose all of the information in the database (ie configurable property selections chosen by the user).

If the user looses the application, I plan to have them reinstall it (which would recreate the database). But I would like them to be able to load a 'configuration' file from their Built in storage area when the app is reinstalled, so that they don't loose all of their settings.

Expererience with this? or reccomendations on how to go about it?

Storage Area Networks?

Does anyone know if SQL7 will work with Storage Area Networks(SAN's)? I've read that SQL2000 implements something called a Virtual Interface System Area Network (VI SAN) that allows communication with devices connected via a SAN.

My site is installing a SAN and I need to know if SQL7 can utilize those resources (Storage,etc) and how reliable if so.

Not Enough Storage Is Available To Complete This Operation

Aug 31, 2004

Hi,

I am having trouble trying to import a big file (aprox 250Mb is size) into an SQL Server database and I keep getting the message:

"Not enough storage is available to complete this operation".

The application tries to import the file by executing a stored procedure:

CREATE PROCEDURE sp_updateMaterialBlob
@MaterialId Int,
@BLOB image
AS
BEGIN
Update Material SET blob = @blob where id = @materialId
END

The application uses an ADO connection. I've tried increasing the memory of the client machine but that didn't work. Whenever I do run the import, nearly all the memory on the machine is used up but every time after several hours I get the same error message. What is the cause of the problem and how do I resolve it? Ideally I want to use my application to do the import rather than anything bespoke.

Bit Datatypes Physical Storage

Feb 15, 2005

Can anyone explain to me how a column defined with a "bit null" datatype is physically stored in MSSQL? Is it stored like a "tinyint null" physically? In other words, how many bytes on the row on the page does a "bit null" datatype consume (assuming a non-null value 0, or 1 is the current value).

Is there any good documentation about the physical storage layout for a data page?

SQL 2012 :: Server On NAS Storage

Oct 28, 2014

I'm in the situation where we are suffering of poor performance on our SAN storage (VPlex) but it is mainly due to the quantity of data of different types which are on it (other applications, other I/O profile, bad storage usage...). As we plan to dedicate an ESX for SQL Server, we decide to have a new storage type. So we will go with NETAPP Clustered Data ONTAP on NAS technology.

Storage team want to enable only NFS protocol, so I'm wondering how SQL Server will handle that ? I read that NFS wasn't optimize for SQL Server and that block level (SAN) should be preferred.
