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.
Regards

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.
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?
Hi, I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time. thanks. varun
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:
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} Description: "An OLE DB error has occurred. Error code: 0x80040E4D. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E4D Description: "Communication link failure". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E4D Description: "Shared Memory Provider: I/O Error detected in read/write operation [4]. ". An OLE DB record is available.

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.
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
when i alter non identity column to identity column using this Query alter table testid alter column test int identity(1,1) then i got this error message Msg 156, Level 15, State 1, Line 3 Incorrect syntax near the keyword 'identity'.
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?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint

I am have this problem, that would not go away, can some please help me. I want to rename or delete column that is bound to a tableadapter using SQL Express at runtime. is it possibleI have no idea on what to do.
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
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.
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.
when i tried to run a DTS which transfer bulk data between 2 SQL servers, i got following error message: ================================================== ============ Error: -2147467259 (80004005); Provider Error: 4815 (12CF) Error string: Received invalid column length from bcp client. Error source: Microsoft OLE DB Provider for SQL Server Help file: Help context: 0 ================================================== ===========
if anybody has encounter the same problem before? after testing, i think it's must related with network traffic problem. but i can not figure out how to solve it.
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.
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: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
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;
Hello; My Memebership table has Guid column as Primary key. But I would like to add Auto numbering Identity column to this table. Is this idea OK or it will bring some problems? Thank you in advance for your help
Hi(SQL Server 2000)I have an existing table (t) with a column that is NOT an identity column(t.ID), but it has manually inserted "row numbers". I want to make thiscolumn become an identity column. This column is a key field to othertables, so I want to keep the row numbers that are allready inserted.From the Query Analyzer, how do I do this?Thanks in advance!Regards,Gunnar VøyenliEDB-konsulent asNORWAY
I have two tables, one a data table, the other a product table. I want to perform a join on the two tables with values distributed into columns based on the value in the month field.

am having a simpleData flow task which trasferes from OLEDBSource to OLEDBDestination. I am repeating the Dataflow task which transfers from sourcetablename extracted from for loop to a destination table var.
The problem am gettting is for the first table it is able to transfer correcly because I did mapping for those tables at design time...but for the next coming sourcetable-desttable (which r having different no of cols,datatypes) its giving Validation failed...and...needs to refresh metadata....
is there any way to refresh the metadata of Data flow task (I set the property of OLEDBSource validate external meta to false then also same error is coming)

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 want to know how to reset the identiy column when i delete a row from the existing table.
Example:
I have a table a with id (identity incr value 1) and name
I have 10 records inserted into it.,which would be from 1...thru...10 i delete a record say 5 then i have 1,2,3,4,6,7,8,9,10, now i want them to be rearranged to systamatic order like 1,2,3,4,5,6,7,8,9 how can i do this.
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.
How does one bcp data INTO a MS SQL Server table that includes an IDENTITY column from a text file that does NOT include a value for the IDENTITY column? Surely, this must be a common process?
