Add IDENTITY Column In Runtime In A View...
Jul 20, 2005
Dear All,
I'm facing a problem with creating a view.I have a table with
following description
Tab1
------------------------------------
Col1 col2
---- -----
Val1 Tom
Val2 Cat
Val3 Jack
Val4 Jim
Now I'm trying to create a view with following information from
Tab1.The output should be
Tab1View
--------------------------------------
Col1 Col2 Col3
---- ---- -----
1 Val1 Tom
2 Val2 Cat
3 Val3 Jack
4 Val4 Jim
---------------------------------------
So the create view statement add this column dynamically in this
result set.
If any body has any doubt on this query please let me inform.

For an ASP.net project, I have had a DropDownList with a static ArrayList.The ArrayList will be defined from a View, where there is no Identity PK.
I also have used cbxDropDownListName.SelectedIndex to add new data toa table, where an Indetity PK is used to reference the ArrayList.
I am wondering how can I add an identity PK to my view?
TIA,Jeffrey

I need a view that will:
1) select the distinct values in a column (the easy part)
2) assign the equivalent of an identity column to each row containing the distinct value it returns.
For example TableA contains 25 records but one of the columns only contains three unique values (say, 'A','B', & 'C').
This is what I want my view to return:
1 A
2 B
3 C
In other words, I need the view to assign the 1, 2 and 3 to the individual rows.
Thanks in advance for any pointers on this one.

Thanks a lot, Greg!
Well, I have another question.
In SQL-2005, till SP2 version, there is a bug, dialed with treating an identity column in a view as an ordinary int column, when the compatibility verison of the DB is set to 80: http://support.microsoft.com/kb/920974
In SQL Server 2005 Express Edition CTP (since version 9.00.3027), which is available to download from Microsoft site, this bug was fixed.
Please tell if you know, how can I get an evaluation copy of any other edition of this version, where merge publication feature could be tested?

Greetings,
I have an ASP.NET web form that calls out to a component which includes the following code which leverages the Application and Package classes in the Microsoft.SqlServer.Dts.Runtime namespace:
Application application = new Application();
Package package = application.LoadFromDtsServer(@"File SystemMyPackagesMyPackage", "MyMachine", null);
string id = package.ID;
Microsoft.SqlServer.Dts.Runtime.DTSExecResult result = package.Execute();
I am logged in to the app as DomainMe.
I have Windows Integrated Authentication configured in IIS and am using Windows Authentication in ASP.NET. I am using impersonation to impersonate a fixed identity, say DomainBob. This has the following effect:
WindowIdentity.GetCurrent() returns DomainBob as expected since the process is being impersonated by DomainBob.
Thread.CurrentPrincipal.Identity.Name returns DomainMe as expected since the ASP.NET application is using Windows Authentication.
The id variable successfuly is initialized to the GUID of the package, proving that the package name is resolving, however, from the ASP.NET application, the package fails.
Issuing the ? package.Errors[0] command at the command window provides the following information:
{Microsoft.SqlServer.Dts.Runtime.DtsError}
base {Microsoft.SqlServer.Dts.Runtime.DtsObject}: {Microsoft.SqlServer.Dts.Runtime.DtsError}

Source: "Packages MyPackage"
SubComponent: "Connection manager "DataMart""
TimeStamp: {12/21/2006 2:18:55 PM}
For some reason, the ASPNET process account is being passed to the package!
This makes no sense, because clearly, DomainBob is impersonating the worker process and all downstream resources should be accessed via DomainBob. This includes SQL Server Database Engine and I would imagine SSIS as well. ASPNET should not come into play at all since I am impersonating.
I also tried using regular (non-fixed identity) impersonation (<identity impersonate="true" />), but again, SSIS is trying to authenticate ASPNET, instead of DomainMe as would be expected.
This is definetely isolated to ASP.NET applications, because making the same call from within a unit test succeeds. It would seem that this is a definete issue because the behavior is inconsistent with ASP.NET security principles.
Has anyone else seen this problem?
Any direction or suggestions very much appreciated.
Thanks,
Rick

Is there any way to view the queries that a SqlDataSource executes against your chosen data source at runtime? i.e. after all the parameters have been substituted with their values.I'm assigning a number of parameters at runtime to its selectcommand, and i'm getting some exceptions thrown when attempting to update or delete records from a gridview using it (it's a really old Synergy database, which can be quite particular about the structure of queries). It would be a massive help if i could actually see the exact queries the datasource is attempting to use.Cheers for any help

I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?

im working on a report which shows the data based on the users input. I have used a matrix because I have no control on how many fields the users want, so practically we have a dynamic column here. My problem is that they require me to able the user to hide the columns he/she wishes to during runtime. We have a previous report that enables the user to hide it during runtime but it has static column. Any idea on how I could do it?... Thank you so much...

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
* I can't change anything on T
* The PK is NOT an Identity

Hi -- I am fairly new to SSIS development, although I am starting to appreciate it more an more, especially since I have started getting into extending the object model. Here's my question:
I have a data flow that pulls data from any number of different delimited files with different numbers of columns. I have had no problem dealing with setting up run-time file locations and file names by using the expressions of a flat file data source, and i have been able to pretty easily deal with varying file delimiters by standardizing the files before they get into the data flow. however, I have not been able to come up with a solution that will allow my data source to discover its column info at run time, and then pass that information on to the data flow task. all i really care about is being able to properly parse the individual rows into individual column data by the flat file data source because the data flow itself is able to discover the actual data that the columns hold at run-time.
i would very much appreciate any feedback from anyone on possible solutions for this.
thanks!

Hi all,
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT
fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE
CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be
created where the referencing column 'child_table.child_id' is an identity column.
any workarounds for this ?

I am trying to find a way to provide three metrics for a table that only provides 2 of them. I need to derive a third column which tallies based on conditions that can be found in the dataset.
The table I'm querying shows
(1) total referrals
(2) total moves
but it is missing a column that tallies whenever the referral moved into the same property_id that it was referred to.
create table dimFacts
(date_value datetime
, month_name varchar(9)
, year_number varchar(4)
, month_number tinyint
[Code] ....
How can I use sql to create one additional column for the above data set, ie. let's call it 'property_conversion' such that on the fifth row there will be a '1' showing that on 2012-12-30 lead_id 10038655 moved into the property it was referred to back on 2012-10-15 ?

Hi guys,
If I have a temporary table called #CTE
With the columns
[Account]
[Name]
[RowID Table Level]
[RowID Data Level]
and I need to change the column type for the columns:
[RowID Table Level]
[RowID Data Level]
to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time.
What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below:

I have tried the code below, but getting syntax error...
ALTER TABLE #CTE
ALTER COLUMN
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE
MODIFY
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;

Having an identity column in target table, how do I use SQL 7 DTS ?
In Import wizard, I chose 'ignore' in source, checked Enable Indenity Insert - DTS failed with a msg like - a column cannot have NULL...
In DTS package, had Fast load and Enable Indenity checked - no luck !
Unchecked Enable identity, do luck.
What would be the standard procs for this since this sounds like a very common
senario.
What I am expecting is to insert from source and SQL would take care identity column automatically.
Appreciate your help very much !

I have a table that has a field that will not accept null values. I was trying to create a new table with a new field that would accept null values. I would then drop the original table and rename the new table. The problem is my key field has the Identity column (Autonumber) turned on. This allows the recordID to be automatically generated. Is there anyway to bypass the Identity Column feature and still keep it there future records? I already tried the "with Nocheck Clause" but does not work.
