I'm using a typed dataset to access my database (SQL Express); I have a table that returns data, which two fields are null; I'm getting this error:
{"Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."}
There are no foreign-key or unique key constraints, so it has to be a non-null issue; I changed the two fields in the table to have a null value of Empty instead of Throw Exception, but I don't understand what the problem is coming from... I'm at a loss.
Hi, Is there any work around to passing a set of strings to a parameter in a Typed Dataset for example I am pasing '4226222172004','4212012182004' which I build on my code the number of items will vary passed on the user selection but since the Typed Dataset uses sp_executesql and the parameters are change to '''4226222172004'',''4212012182004''' Any ideas how I can format the Parameter I am passing.so that it will end like where in ( '4226222172004','4212012182004') instead of where in ('''4226222172004'',''4212012182004''') I again the number of parameters will very. Thanks Julio D
When I insert the fields using parameters, the params look like this: paramValues(10) = New SqlParameter("@RegHrs", SqlDbType.Decimal) paramValues(11) = New SqlParameter("@OTHrs", SqlDbType.Decimal) paramValues(12) = New SqlParameter("@TotHrs", SqlDbType.Decimal)
The fields in the SQL table are defined as: RegHrs - decimal (9,2) OTHrs - decimal (9,2) TotHrs - decimal (9,2)
Before I insert the row (from w/in the VB code), I stop the code and verify that the values being placed into the params are: 5.85 0 5.85
After the SQL insertion, the values w/in the SQL Table contain: 6 0 6
Hi, I am trying to use a typed dataset created using the Query builder which returns the data correctly when I use 'Execute Query' in query builder but as soon as I attempt to return a dataset using the GetData method created I get the following error: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Which is not very helpful, any ideas where the problem may be? I have tried switching off enforce constraints and setting the NullValue property of all strings to 'Emtpy' bu that has no effect. Thanks in advance
I'm need to use typed Dataset with CLR UDT, but when I'm trying to create TableAdapter in Dataset designer, I'm gettng error message: User-defined data types are not supported in DataSet designer
Hi all,I am using a Strongly Typed DataSet (ASP.NET 2.0) to insert new data into a SQL Server 2000 database, types of some fields in db are nvarchar. All thing work fine except I can not insert unicode data(Vietnamese language) into db.I can't find where to put prefix N. Please help me!!!
Hi, I have a little question. I searched google, and could not find good answer for this one. I have a stored procedure that returns two tables. Usually I generate a dataset out of a stored procedure by dragging it to the dataset. When I drag this one it creates a DS with only one table, the first one. How can I make it use both tables?
Using VS 2008 Beta 2, SQL CE 3.5, on desktop, and Typed Datasets: The INSERT command of dataset table adapter does not return the updated identity of inserted row. Why?
also every time I want to modify the insert command to return the updated identity of inserted row, i get the error: "Unable to parse query text."
I'm at loss how I'm supposed to work with typed datasets and Sql Server Compact 3.5, when inserting records and I need to update my datatables with the primary key of newly inserted rows.
I've tried adding a RowUpdated handler to all tableadapters that look like this:
I've previously used this type of approach when working with an OleDbDatabase, which works just fine. But it doesn't work with Sql Server CE 3.5, and since it doesn't support stored procedures I can't fix it that way either. And it doesn't support commands in a batch (i.e appending the Insert command of the adapter with ";SELECT @@IDENTITY") so that doesn't work either...
So how are we supposed to use Sql Server CE 3.5? It's impossible together with datasets? Or am I missing something obvious?
I am trying to upload a file in ASP.net 2.0 to a SQL database using the FileUpload control. I am doing this by way of a typed dataset.Here is my code.Dim rta As New ResponseTableAdapterDim rdt As ResponseDataTable = rta.GetResponseByID(1)Dim rr As ResponseRow = rdt(0)Dim fs As New FileStream(fu.PostedFile.FileName, FileMode.Open, FileAccess.Read)Dim br As New BinaryReader(fs)Dim image() As Byte = br.ReadBytes(fs.Length)br.Close()fs.Close()rr.UploadFile = imagerr.NameFile = fs.Namerta.Update(rdt)The code runs without an error but afterwards I find that nothing has been stored in the UploadFile cell in the database but the file name has been stored in the NameFile cell in the database. Any ideas?Your help is much appreciated. James
Like the subject says, I'm using strongly typed datasets. I'm using to designer to create the datasets and the methods. I can select and insert, but I can't update or delete. I right click on the adapter bar and select Add Query. I sleect 'Use SQL Statements'I select 'Update' (or 'Delete')I get a sql statement pane containing the word 'Update' ('Delete') and asking 'What data should the table load?'I can click on next, but anything else gives me errors. I'd list them, but I'm clearly doing something wrong and it's probably obvious. Diane
I am using typed data sets. When a certain line of C# code is reached, I get the following error message: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Here is my source code. I altered the table to remove all contraints and primary keys, but I still get the error message. The erroroccurs when the last line of code is reached. (_DeltaTable = myAdaptor.GetData();) The code is listed below. Does anyone know whatis going on? calculateValuesAndAveragesTableAdapters.FundamentalsTableAdapter myAdaptor = new calculateValuesAndAveragesTableAdapters.FundamentalsTableAdapter(); calculateValuesAndAverages.FundamentalsDataTable _DeltaTable; _DeltaTable = myAdaptor.GetData(); // Error occurs on this line
OK so I have this SSIS package that uses a connection call "Conn1". I added this to my configuration file (which also contains connections called "Conn2" and "Conn3" which are used by other packages. Works fine in DEV when run via SQL Agent. I moved SSIS package and config file to prod server. SQL Agent now throws error on this package saying it cannot resolve path to "Conn3". This package doesn't use "Conn3"... I opened both the SSIS package and the Config file in notepad and verified Conn3 wasn't referenced in the package... HELP !!!!
I am new to SSAS and learning mdx, I am running the following query but it is throwing error "Parser: The syntax for 1 is incorrect",
Select [Measures].[Order Quantity] on axis(0), [DimProduct].[Product By Category].[ProductCategory].members on axis(1) From [ResellerSales] where Except({[DimProduct].[Product By Category].[ProductCategory].members}, {[DimProduct].[Product By Category].[ProductCategory].&[1]})
Sorry seem to be havign no end of trouble with SQL today. I need to create a query that will rank tickets using the row count of another table which has a relationship with the primarykey of that ticket table. I decided to spilt it into two querys, one which gets the count each ticketid has within a date peroid and relating to a os:: SELECT COUNT(*) AS count, Tickets.TicketID, Systems.OSFROM Rating INNER JOIN Tickets ON Rating.TicketID = Tickets.TicketID INNER JOIN Systems ON Tickets.SystemID = Systems.SystemIDWHERE (Rating.DateVoted >= @date)GROUP BY Tickets.TicketID, Systems.OSHAVING (Systems.OS = @osid) This works, BUT when I put in the date using: command.CommandText = "SELECT COUNT(*) AS count, Tickets.TicketID, Systems.OS FROM Rating INNER JOIN Tickets ON Rating.TicketID = Tickets.TicketID INNER JOIN Systems ON Tickets.SystemID = Systems.SystemID WHERE (Rating.DateVoted >=" + Datetime.Now.Adddays(-7) + ") GROUP BY Tickets.TicketID, Systems.OS HAVING (Systems.OS =" + 1 + ")"; And it throws up an error saying there was a syntax error at '22' (the hour I am currently on). So: Any idea how I can fix thisAny ideas on creating a query that will do the above, but also return the ticket informationHow do you link querys (I might have to do this if I can't work out 2)Please, If anyone has any ideas. This is driving me crazy
i have a data flow configured to use a ole db source. the ole db source uses an ole db connection manager pointing to the adventureworks db which suceeded when i tested its connection. the data access mode of the ole db source is "sql command". below is the sql command text:
SELECT SpecialOfferID, Description DiscountPct, Type, Category, StartDate, EndDate, MinQty, MaxQty, ModifiedDate FROM Sales.SpecialOffer WHERE ModifiedDate >= ? AND ModifiedDate < ?
this query uses 2 paramaters, each of which is mapped to a datetime variable which falls with the range of the ModifiedDate column as follows:
Parameter0: User::ExtractStartDate
Parameter1: User::ExtractStopDate
ExtractStartDate is set to 7/1/2001 and ExtractStopDate is set to 3/31/2004. however, i get the following error when i press the preview button in the ole db source editor: "there was an error displaying the preview. additional information: no value given for one or more required parameters (microsoft sql native client)".
as far as i can tell, i have the ole db source configured correctly. thus, i can't figure out why this error is being generated. has anyone else experienced this issue? if so, were you able to resolve it? is this a bug?
I have managed to cobble up a VS2005 PPC app that has 10 or so tables in it. Of course when I started binding to the tables in my app, pretty soon I ran into an error I had made defining a datatype for a column in one table. Single instead of string. I have spent most of the day trying to modify something to change this column datatype. No luck.
1. Seems you cannot edit the schema in VS2005 to modify the datatype. After messing around, now the project will not open at all.
2. Cannot get the ADS wizard to go anymore, so cannot make .mdb schema change and pull down updated column/table.
3. Thought SQL Server 2005 had a tool you could just open up a .sdf file and change the schema. No luck. At least no intuitive way showed itself after I installed it.
4. Thought SQL Server Express Editition could open such a .sdf file and modify it so installed it. Again, could not figure out how this works either.
I suppose I could start over from scratch and create a new app datasource/dataset in VS2005, but I have done that so many times before, I am getting crabby thinking about doing it again. There must be a better way??? Isn't there?

My BIDS installation is able to create new projects and open saved ones, but if i try to add an existing package from a remote server, it throws the error pasted below. I can see the package list, but once i choose the package, hit ok, then hit ok to load it, I get the error. I can open the same package on a different computer, so it's not user rights related.

I have some questions about creating SQL Server CE databases. Based on my experiments and what I've read on these forums, it looks like there are a couple ways to create a database schema. I can edit the database schema via the Server Explorer in Visual Studio, or use an external program like SQL Server Management Studio and somehow convert those files to .sdf files.
I find Visual Studio's built in tools to be cumbersome to use and limited in functionality, and using SSMS seems like a roundabout way of approaching the problem. I understand Microsoft will be releasing better tools with Orcas, but in the meantime, I'm wondering if there are alternative ways to generate database schemas.
For instance, I find Visual Studio's DataSet designer fairly easy to use. The DataSet designer generates schema definitions (.xsd files), and an instantiated DataSet can both read and write schema definitions via Read/WriteXMLSchema. Furthermore, DataAdapter's Fill and FillSchema methods can be used to push a schema from a database to a DataSet. So, can I somehow go the other direction and push a schema from a DataSet to a database? It seems like all the tools are there...
For example, if I create the DataSet schema, could I use a small app to create a new .sdf file, instantiate a DataSet, write the schema from the DataSet to the database, and then save the .sdf file? Or given the generated .xsd file, is there any way to create a SQL database from that?
I am writing the following code in my SSIS 2012 script task.I am deliberately trying to fali this code by adding some typos in the connection string.I want to catch the exception and display the exact exception message.but SSIS runtime is always throwing same error message as follows:

I created an Image for the Database in sqlserver 2000. When I am querying directly the database as "Select * from employee", it is returning the result set.
But, when I am querying Database image with same query. It is giving error
Server: Msg 208, Level 16, State 1, Line 1 Invalid object name 'Employee'
It is expecting the Database Owner. If I do query like "Select * from [Owner].employee", it is working fine.
My requirement is not use owner in queries, it should be simple query ("Select * from employee").
Can any one, help me out. Thanks in advance. Bhupesh
All- I'm a newbie working on a VWD project. A couple questions arose when attempting to work with a project's dataset and its underlying SQL Server Express database:
Is it true that when changing the schema of a database in SQL Server Express through the VWD Database Explorer, one must take care to manually make parallel changes in the dataset? For example, if you make a relation between two tables in Database Explorer, you must do the same with the counterpart tables in the dataset? For example, I find that if I delete or create a relationship between two tables in the database, I must manually do the same in the dataset.
I developed a custom data flow task in .net 2.0 using Visual Studio 2005. I installed it into GAC using GACUTIL and also copied it into the pipeline directory. This task runs absolutely fine when I run it on my local machine both in BIDS and using the script in windows 2000 environment. However, when I deployed this package into a windows 2003 server, the package fails at the custom task level. I checked the GAC in windowsassembly directory and it is present. Also I copied the file into the PipeLine directory and verified that I copied it into the correct pipeline directory by checking the registry. The version of the assembly is still Debug. I looked up documentation in MSDN but there is very little information about the errors I am seeing.
The error I get is pasted below, Can somebody please help me as I am currently stuck and running out of ideas to fix this problem.

We have written a multithreaded application in which we are maintaining separate Database connections for each thread. these connections are opened and closed at the start and exit of the thread.
We have observed that even if there is only one thread running ( application thread), execution of simple Select queries some times throws Native exception(Error - 0xc0000005 ).
This error comes intermittently. Execution of same query doesn't throw exception.
Further investigation by breaking the debug at the time of native exception and then looking into the stack trace shows that native exception has occured at one of the Native API (CompileQueryPlan() ) which is being called implicitly by the SQL Mobile.
Each time when we see native exception stack trace shows failure at CompileQueryPlan() call.
Let me know if this is a known defect in SQL Mobile 2005 or there is something else that is causing native exception.
I am trying to return a record from my sqlDataReader in 2.0. Here is the code that is throwing me: Dim strSQL As String = "SELECT login FROM (Table) WHERE (username = 'something')" Dim sqlDataReader As SqlDataReader Dim ConnStr As String = "connectionString" Dim myCn As New SqlClient.SqlConnection(ConnStr) Dim myCmd As New SqlClient.SqlCommand(strSQL, myCn) myCn.Open() sqlDataReader = myCmd.ExecuteReader(CommandBehavior.CloseConnection) The error that I'm gettin is this: 'Incorrect syntax near ')'.' and its on my ExecuteReader line. This works for me in 1.1 but not 2.0. Any ideas as to why? J
Is it possible to return typed data in an Endpoint for an ASP.Net Web Reference to Proxy? If so, is there any specific terminology I should be aware of to target my search?
I realize there is a choice between Object (returns a dataset or error) or dataset, but the automatically generated WebReference Proxy in ASP.Net (2.0) is untyped and we can't change the typing there as you have to remove the entire WebReference to pick up new WebMethods (or changes to signitures I'd assume).
I'm able to create my own typed proxy as a psuedo-DAL assembly which takes the WebReference and cast rows/objects into typed rows/objects one at a time, but this seems like a lot of work and probobly not the best practice.
I am calling a stored procedure that looks like this.

IF @Accounts = 0 BEGIN RAISERROR('E-mail address not found.', 10, 1) END ELSE BEGIN SET @Count = (Select Count(*) from Users Where UPPER(Email) = UPPER(@Email) and Password = @Password)
IF @Count > 0 select 1 as Verification ELSE select 0 as Verification END END
When I enter a login that does not exist, the error is not thrown in .net. Tracing the code shows normal execution. What am I doing wrong?

I have a DAL that uses Typed DataSets (not directly, the DAL references and calls the dataset methods) and I am receiving a "There is already an open DataReader associated with this Command which must be closed first." error when I render an ASP.NET page where two imgs need to retrieve two different versions of an image (a thumbnail and a full sized image).I am using SQL Server 2005, ASP.NET 2.0, and my connection string includes the MARS attribute set to true. This is the method in the SqlServer DAL, _images is a typed table adapter:public override Image SelectImage(Guid? id) { // TODO: Find out why MARS feature isn't working! DataSet.ImageDataTable dt = _images.SelectImageById(id); <-- Exception occurs here if ((dt != null) && dt.Count == 1) { DataSet.ImageRow row = dt[0]; Guid? keyId = null; if (!row.IsKeyIdNull()) { keyId = row.KeyId; } // Success return new Image(row.Id, keyId, row.Path, row.Caption); } return null; } // This is the method that is called for both images, which calls the DALpublic class EntitySearch{ public static Image ImageById(Guid id) { return _dal.SelectImage(id); }}// These are the code-behind methods that the image response strings will come from...imgThumbnail.ImageUrl = String.Format("../Services/ImageBroker.aspx?img={0}&mode=Thumbnail", image.Id);imgFullImage.ImageUrl = String.Format("../Services/ImageBroker.aspx?img={0}&mode=Image", image.Id); // And finally here is the code in the broker class that saves the images to the response streamImage image = EntitySearch.ImageById(imageId);using (Picture picture = (mode == ImageMode.Image) ? image.Picture : image.Thumbnail){ Picture.Save(response.OutputStream, ImageFormat.Jpeg);}So the final snippet of code is being called twice, and it crashes. I have tried closing the connection and reopening it as a workaround but this only yields strange results, though it intermittently does load the images.Can anyone spot the issue?
I dragged two tables into the dataset designer. And I have a query with a resultset over both of the tables (joined).Is there ANY way I can have a strongly typed datatable out of the resultset?The automatically created dataset adapters won't allow me to create a tableadapter or datatable for the joined resultset but for one single table at a time only.Any solution to that? Theoretically it should be possible since I don't "lose" any type information with a join.. why can't I have a strongly typed datatable over the resultset?The join is not very sophisticated. In fact it couldn't be any more simple.(I'm refering to my previously posted question at http://forums.asp.net/t/1220481.aspx)
