Hi,
How can I retrieve generated identity value after insert a row into table in case I can identify inserted row?
(the INSERT statement is dynamic constructed and queried from data access layer, not in stored procedure)

Hi Guys,
Well, the big re-write of our app in Russia is an official failure and it has come back to us (after 2+ years at $20K per month). I suggested we get the data model straightened out before we do anything else.
Here's a notion that I'm expecting to have to stomp, but I thought I'd run it by you smart guys first.
Basic structure will be Admin DB as a hub and each customer (because they all request this anyway for 'security') will have a separate DB for their Disability/Leave data.
As an additional layer of 'security' it was requested that, say, the unique id of a person would be unique across all client databases. Hence if the interface queries medical info on Person 123 for Customer B there is no possiblity of accidentally returning Person 123 from Customer H, because 123 only exists as a primary key in the Person table in Customer B's database. Each available key number is used uniquely across the admin & customer databases. (As you may guess, we've had several instances of company a's data going to company b.)
We're new to the idea of splitting out customers into separate DB's but our plan is to keep the customer DB's identical in every aspect except data.
Is there a functional way to ensure a key's uniqueness across our whole structure (Admin DB as Hub and multiple client db's)? Are we nuts to want this?
Note I did look at some info on 'creating your own identity' key thinking that maybe we could keep an 'identity' in a table in the Admin DB for each client table that needs this feature. But it sounds like I'll end up with issues for sure when bulk inserts are run unless the insert is run on the table in the Admin DB.
I can't imagine anyone is going to try to answer this, but it made me feel better to type it all out here!
I need a script that returns the last identity value generated for each table in a database that has an identity column.
I am using SQL Server 2005.
Thanks.
Ok, let's say that I do a following inline INSERT statement.....
INSERT INTO Car ( carMake, carModel ) VALUES ( 'Honda', 'S2000' )
When I do this, a carId int value will automatically be generated because it is the Car table's PK and is an int identity. How do I obtain this value so I can immediately use it in let's say, the following example.
INSERT INTO Person ( carId ) VALUES ( @carId ) ..... where @carId is the value I need
Maybe you would say I should do something like.....
SELECT carId FROM Car WHERE carMake = 'Honda' AND carModel = 'S2000'
However, let's assume that the carMake and the carModel fields are NOT unique. I'm sure there's an easy way to extract the new identity value (maybe even in the same query) as the INSERT, but I just don't know how.
Thanks.
Hello
I tried the Beta 1 of the service pack 1 to .net 3.5. If I try to add an entity (and try to save this), I get the Exception "No support for server-generated keys and server-generated values".
How can I add entities to my Sqlce- database?
I tried to give the id- column (primary key) in the database an identity, another time without identity, only primary key --> none of them worked. I always get the same error.
What do I have to change to make successfully a SaveChanges()?
Thanks for your help,
Gerald
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
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've a problem with auto-generated key. In my parent table, some lines have been deleted. I would like to add new lines with the same content in order to restore my database, but I cannot decide on the id value which is an auto-generated key. Is there a solution to set an auto-generated key with a specific value ?

Suppose I want to generate a table as below
No. Col1 Col2
1 100 Alan
2 110 Alan
3 120 Alan
In Column I there is a sequence of numbers from 1 to 3 with a step of 1
In Column 2 there is a sequence of numbers from 100 to 120 with a step of 2
In Column 3 there is a name that is repeated accross the whole column
Can I generate such a table with just a single SQL Statement . I don't see any reason why it should not be possible. We know the logic to generate all the numbers of every row. It would be possible using a while loop , but that is be tedious and I am looking for a better way.
One application I can think of is, Suppose I want to find out all deleted primary key ids from a table or say if I have a set
(1,2,3, 7,8,9) , and wish to know the missing numbers in the range 1 to 9. If an sql like above is possible I could use it in a left join to get me the desired output.
Could anyone tell me if it is possible and if not , why not ?
Thanks,

Hi,
Is there any way to look at behind-the-scene SQL query that gets generated by SSRS engine to pull the data out of the data source (particularly SQL Server).
So far, I only know that you can see the query generated by semantic query engine by changing trace option in configuration file.
Thanks and Regards,

Hi
I have a windows application. I am using following code right after setting the LocalReport ReportPath. Report rendering is too slow if use following line of code and Report viewer does not show spiny and the text that says €śReport is being generated.€?
Me.ReportViewer1.SetDisplayMode(DisplayMode.PrintLayout)
Me.ReportViewer1.ZoomMode = ZoomMode.Percent
Me.ReportViewer1.ZoomPercent = 80
Please advise how can make it fast and show spiny.
Thanks in advance.
I have created a report and deployed it successfully to a seperate machine with SSRS on. Both my dev machine and the SSRS machine are in the same workgroup. I can then Browse to the Report Manager though IE and click & run the report (The connection is using integrated security). The report requires a single parameter to be entered which once done works successfully. The report has a single table, an inbedded image and a few static fields in the report header.
If I however add a report viewer control to an aspx test form all is not well. As soon as the page opens I am prompted to enter the parameter which is good news as it shows there has been some communication with the SSRS metabase. I then click the view report button. Using Profiler I have proved that the report Stored Proc. is running with the correct parameter value. The report viewer however seems to hang and only displays "Report is being generated" without displaying the results. It does this even with a timeout set of 1000ms.
I don't think this is a security issue as both the Report Manager works and the test form prompts me for the parameter and effectively runs the report SP. I can only assume it is a problem with returning the report to the browser.
Does anyone have any insight?

Hi,
I created a PDA application with a database, which has a table with a uniqueidentifier field and primarykey.
While doing the bulk insert from dataset into sql mobile database, It is inserting the record but it is not inserting the id which was entered into the sql server 2005 database, instead the id by creating a new id and the code is as below.
conAdap = new SqlCeDataAdapter(strQuery, conSqlceConnection);
SqlCeCommandBuilder cmdBuilder = new SqlCeCommandBuilder(conAdap);
conAdap.Fill(dsData);
int r =conAdap.Update(dsData);
Please help me.

Hi,
I have a report which doesn't work. It has a datatset based on a store procedure. The store-procedure take 10 to 50 second to execute, depending on the parameters.
But, I can't never see my report as i wait more than 10 minutes and it's never generated.
So, I have think that maybe it could be because of the matrix inside the report, so I have try to create another report which have the same dataset but with nothing inside, just a textbox, and it doesn't work too !!
So now, i'm very disapointed and I don't know what to do !
Someone can help me please ? It's very important.
Thank you.

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
I created a new DataSet object using the
wizard and had no probs, it's very straightforward. I created a
GetProducts() method and also added a GetProductCount() method. I
read somewhere that when the DataSet is saved, it will generate the
TableAdapter classes and store them in the project nested under the
DataSet object. This isn't happening, the files aren't there and
yes I'm displaying all files. There *is* however the TableAdapter
class but it's in not in the project, it's a temporary file w/ the
following path:
C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET
Fileswebsitef38f8b5500014aeSources_App_Codepw_products.xsd.72cecc2a.cs.
I saved the DataSet several times, compiled the entire solution and
even closed the solution yet this temporary file isn't getting saved
where it should be. Does anyone have any ideas abt this?
I'm eager to start developing my DAL and def want to use these
TableAdapter classes.
Thx in advance,

Can someone explain the generated sprocs of VS2005 if one column can be nullableDependentOfSeqID = @Original_DependentOfSeqID OR ((@IsNull_DependentOfSeqID = 1) AND (DependentOfSeqID IS NULL))In VS2003 the generated sprocs would beDependentOfSeqID = @Original_DependentOfSeqID OR ((@Original_DependentOfSeqID IS NULL) AND (DependentOfSeqID IS NULL))Which is the best?

I ran a SP that lists fragmented tables in our DB which listed almost all the tables and indexes in the DB. The list includes index names that start with "_WA_Sys_tablecolumn name_.....". Are these SQL Server generated indexes or are these statitics on the tables? What are they? If these are system generated indexes as I thought they were, how are they generated? Can these indexes be dropped or should one want to? IF so, how? Any effect on the DB performance if dropped?
Thanks for your advise.

I am using Enterprise Manager to generate a script of the stored procedures on my database. Under File|Options, I selected Windows Text(ANSI). The file which is generated contains all stored procedures, but there are some procedures which are so long that they wrap to the next line.
When I then try to run this script from ISQL in a batch file, those procedures which wrap error out. Is there any way to generate the script in a more formatted manor, avoiding the wrapping?
I'm having trouble getting the namespaces correct in the XML that is generated by SQL. The XML consists of two parts: a header part with some context information and the payload part with the actual data. With my current SQL script, the namespace is also copied to the payload part.
Here are some DDL and DML scripts to generate two test tables and some test data:
Code:
CREATE TABLE dbo.context(
idintNOT NULLconstraint pk_dbo_context primary key,
namenvarchar(100)NOT NULL
)
INSERT INTO dbo.context(id, name) VALUES (1, 'Here comes some great context information.')
[Code] ....
This is my current FOR XML script that generates the XML:
Code:
;WITH XMLNAMESPACES (DEFAULT 'http://services.registersubscription-02_00.a.cool.url.com')
SELECT
CEXT.name AS [Context/Name],
(SELECT
CONT.id AS [Content/Reference],
[Code] ....
This generates this XML (notice that the namespace is repetated in the <Questions> element):
Code:
<RegisterSubscription xmlns="http://services.registersubscription-02_00.a.cool.url.com">
<Request>
<Context>
<Name>Here comes some great context information.</Name>
[Code] ....
The XML should be like this:
Code:
<RegisterSubscription xmlns="http://services.registersubscription-02_00.a.cool.url.com">
<Request xmlns="">
<Context>
<Name>Here comes some great context information.</Name>
[Code] ....
The generated XML does not pass the XSD validation.

Hello,
I am working with an .xml file that I want to break up into various tables. A couple of fields in my xml file include html tags (<p> tags specifically). The generated xsd file thinks these are nested xml tags and creates a "P" table for the information contained. Is there a way I can modify the generated xsd within the designer? Or is the only way to fix this is to manually modify the xsd?
There is also an <id> tag within the xml. However, SSIS is not using that <id> as the primary key as it adds data to the various tables that I've specified. Instead it appears to be creating its own primary key - calling it "Id". Is there some way to specify that SSIS use the <id> tag contained within the xml instead of creating its own primary key?
Thank you for any help.
When your report datasource is a cube, MDX is generated when you use the design view. In the MDX editor the generated MDX can be viewed. Using parameters I always get a where clause with code like the following:
IIF( STRTOSET(@OrgLevelname, CONSTRAINED).Count = 1, STRTOSET(@OrgLevelname, CONSTRAINED), [Organisation].[Level 2 name].currentmember )
I like to understand what is generated. Is there something I can read on the generated WHERE clause (I do understand the generated SELECT and FROM clauses)? Or can someone shed a light on it?
Why does the MDX need to branch on 'Count = 1' In what way does the result slice my data when Count = 1 or when Count <> 1?
Thanks,
