How Much Storage Does A Null Xml Datatype Column Use If...
Sep 27, 2007
1) it is in the same filegroup as the rest of the table?
2) it is stored in a filegroup separately from the rest of the table (I think this is allowed)?

Storage Of Null Columns
May 23, 2007Hi,
This question comes without the wish for any philosofical debates concerning NULL
Normally SQL Server 2005 uses 13 bytes to store a NUMERIC(22,7) value. Does it use the full 13 bytes when the column contains NULL as well? And what about DATETIME and (BIG)INT? Most of the info on storage of NULL values is about varchar/char/nvarchar/varchar...
Thnx, Jeroen.
SQL Server 2012 :: Storage Of VARCHAR (MAX) When Null
May 7, 2014If 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?

Datatype Of NULL
Oct 17, 2007Hello,
What is the Datatype for NULL ? How SQL Server stores NULL ? I have seen many discussions on this. Some say's that NULL will be considered as character type, then what about NULL value comes in a number column ?
Another article say's NULL is untyped. It don't have any type. Which one is correct ? Will there any difference for NULL in SQL Server and Oracle ?
Any help would be appreaciated

I'm using a table to hold data that I can pass back to the original form page and re-populate the fields that were not validated correctly. The stored procedure either inserts or updates the record in the temp table I've created.
So, currently, as I'm testing, I'm just passing empty values to all the parameters and the @state parameter is failing and throwing the error.
I've double checked that the table has the state column set to integer datatype
The column is set as follows:
Name datatype length Allow Nulls
----------------------------------------------
State int 4 checked
I have tried setting the default value for every column to Null in the table and then also not using a default value. Either way, I still recieve the same error?
Not sure what else to look at?
It seems the problem might be that instead of a null value being passed to the parameter that it is actually empty. Can passing an empty value to a column of datatype integer cause this problem? If so, is there a way to correct it?
Thanks for any help.
Does NULL Inherit A Datatype After Convert
Jun 16, 2015i have a little confusion...
DECLARE @name varchar(30)
SET @name = NULL
SELECT ISNULL(CONVERT(DATE,@name),'')
Result: 1900-01-01
But..
DECLARE @name varchar(30)
SET @name = NULL
SELECT ISNULL(@name,'')
Does NULL inherit a datatype after convert?

SQL 2012 :: Distinct Storage Tier Of Remote BLOB Storage (RBS)
Oct 27, 2014How 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;
NULL Values To Sequential Number (The Field Is Nvarchar Datatype)
Jun 16, 2012Ok I have upgraded my works database from a poorly designed Access database to a SQL database. The previous system allowed NULL values and duplicates to be inserted into a field that should NOT ALLOW NULL Values or duplicates. Therefore, this issue has now been moved across to my new system as I cannot set these constraints on the field that has multiple NULL values.
My solution would be to use a sequential operator, so whatever = NULL would be changed to a sequential number that us as administrators would know was a bogus number starting at something like = 999999900 counting up from that. There are only 250 records that would require updating.
To make things more interesting this field is not a integer type, its a Nvarchar type as its a Hardware ID. Both numerical and characters are require.
Transact SQL :: Based On Data Convert Datatype And Make Wrong Date As NULL
Apr 21, 2015In the below scenario we are inserting some time related fields in Temp table.But its data type is varchar. Once data loading is finished in the temp table (Data is loading by source team SQOOP and they are unable to load if the source datatype is having Date or datetime) we have to alter the column datatypes. somehow, some character data in inserted in date columns (look at into 3rd insert statement). while altering the table it is failing. Can we do any alternative for this (Means if any varchar data that is non convertible to date can we make as null)
INSERT INTO ##TEMP_TEST
SELECT '2014-09-30','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM'

T-SQL (SS2K8) :: Cannot Define Primary Key Constraint On Nullable Column But Column Not Null
Sep 30, 2014We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change
DECLARE@size varchar(5)--The new size of the column
DECLARE @TSQL varchar(255)--Contains the code to be executed
DECLARE @Object varchar(50)--Holds the name of the table
DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10)

They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1
Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'.
Msg 1750, Level 16, State 0, Line 1

View 1 Replies View RelatedCan't Install IBM Tivoli Storage Manager Server On Windows 2003 X64 Storage Server, How Can I Fix The Pkg?
Jan 14, 2008I 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.

Changing The DATATYPE Of A PUBLISHED COLUMN
Oct 27, 2003Hi guys,
Is there any way or method to CHANGE the DATATYPE of a column in a published table being used for transactional replication (MSSQL 2000), WITHOUT DROPPING THE SUBSCRIPTION ????
Im stuck in this mess and do have the option to drop the subscription, alter the table, create the subscription and rerun the snapshot or to recreate it by Manual Synchronisation either.
Can anyone help? Has anyone been across this dilemma before and have troubleshooted the problem? If yes, help is much appreciated.
MY PROBLEM:
~~~~~~~~~~~~~
'MyTable' is currently being published and has subscriptions to it. The PRIMARY KEY column 'id' has an Identity property as well. 'id' is of datatype smallint, however because of bad planning, i now need to change that datatype to an integer to support a larger range WITHOUT DROPPING SUBSCRIPTIONS.
I CANT DROP THE COLUMN EITHER AS IT IS BEING THE PRIMARY KEY COLUMN.
IS THERE ANY OTHER WAY I CAN DO TO ARCHIEVE MY GOAL? THANKYOU.
