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.
I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this? Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Hi, I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error. e.g MOB 401.908.804 - Fails 0401.907.324 - okay 8239 9082 (pager) - fails Anyone got an idea on how to fix this???? Regards.. Peter.
I have to admit I'm pretty new to ASP.net. I'm trying to insert a row of data into my SQLExpress database table "Prets" I'm getting the user_ID from the table "Membres" Here's the code I have: Imports System.Web.UI.PageImports System.Security.PrincipalImports WiseNetTableAdaptersPartial Class membre_sec_Pret_demande_pret Inherits System.Web.UI.Page Protected Sub submit_btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit_btn.Click Dim User As String = My.User.Name Dim pretAdapter As New PretsTableAdapter Dim membreAdapter As New MembresTableAdapter pretAdapter.AjouterPret(Convert.ToInt32(membreAdapter.GetUserIDbyName(User)), Convert.ToDecimal(montant_txt.Text), Convert.ToString(raison_txt.Text)) End SubEnd Class And here's the error I get at runtime: Failed to enable constraints.

Hello there, I have a table under SQL2005 express with 8 fields with a primaryKey defined.In my BLL in the table adapter there is one "SELECT DISTINCT prodCAT from prods" The prodCAT is a nvarchar(50) and it is not part of an index or primaryKey.When I preview the data from my BLL I get the correct data.I defined a new web form (aspx) and put a ddl (dropDownList) with an objectdataSource that relates to the above sql function/command and I get a"Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." BTW when I defined the above SQL in the BLL I got a "The new command text makes the function return data with schema different from the schema of the main query" Any suggestions???
does anyone had any idea on the following codes that i'm facing?i have no ideas what is constraints and i hardly can view my page. In addition to that, i also faced the same problems when i'm trying to change my user password. it eventually managed to change the password but then the changes leads to the failed to enable constraints too. however, the following codes is not related to the change password but the purchase item. Hope someone can help me up! thanks!

Hi, I have two tables (Accounts and Contacts) that have a many-to-many relationship, maintained by the AccountContactLinks table. I would like to populate a Contacts DropDownList with all of the Contacts associated with the Account Selected in Accounts DropDownList. Here is the (SP) SQL Query I'm trying to make work: SELECT Contact.ContactID, Contact.ContactLastName, Contact.ContactFirstName, Contact.ContactLastName + ', ' + Contact.ContactFirstName AS ContactName FROM Contact INNER JOIN AccountContactLinks ON Contact.ContactID = AccountContactLinks.ContactID WHERE (AccountContactLinks.AccountID = @AccountID) ORDER BY Contact.ContactLastNameEND I keep getting the following error: Failed to enable constraints. One or more rows contains values violating non-null, unique or foreign key constraints. I haven't implemented any non-null, unique or foreign key constraints between any of these tables, so suspect that I've got the SQL Query wrong. Thanks very much. Regards Gary
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
Hello,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.Thanks.
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
Is there any procedure or option to disable and enable constraints on database.the problem is we are having lot master and child tables. when i am trying to move the entire data from original db to another same db, there i am getting constraints problem. child tables are not accepting data with out loading the master tables.
is there any to disable and enable constraints? please give me reply asap
Using VS 2008 I got a Windows Smart Device project targeting WM6 Standard and using .NET CF 3.5. I add a new database file = creating an empty Compact 3.5 database (creates an sdf-file in my project). Then create an empty dataset in the wizard (creates an xsd-file in my project). Then I add a couple of tables in the database. After that I want to use my earlier created dataset. I mark the xsd-file and looks in Poperties. I get the error when I try to change Custom Tool value from 'MSDataSetGenerator' to 'MSResultSetGenerator'. Why????
When updating data using .NET 2.0 SqlDataAdapter and a strong typed dataset, it seems that constraints (foreign key) and trigger are disabled. I'm using a stored procedure to delete rows and calling it from SSMS causes the trigger to fire. Calling it via the SqlDataAdapter not.
Can someone confirm this?
At least here, my triggers don't fire.
How can I enable, that triggers in SQL Server do fire?
Are there differences in this behaviour when using batch updates or not?
I currently have serverA importing data from an AS400 oledb connection and serverB on hot-standby as a mirror. The data import is being performed via an SSIS scheduled job.
I've yet to implement any solution in the following case: If the database on serverA fails, it will failover to the mirror. But the jobs will still be on serverA. Ideally, I'm assuming the jobs should not run on serverB since it will be attempting to update the mirrored database. So, I am wondering if both servers can have identical copies of SSIS packages and jobs and simply (?) enable or disable them based on which server will be hosting the principal database.
Is there any solution where the jobs can automatically be disabled on the server with the mirrored database and enabled on the principal database depending on its status?
I got this Error, Query Execution for Dataset 'Source'.
When i try to run a report that is actually a drillthrough from another report. It runs fine in Report Designer, and when i deploy to my Local server. But when i deploy it to my virtual Report Server, I get this error messege. Why is it doing this? and where can i see errors for this type of stuff, so i can figure this out. This uses the same Datasource as the report linked from it. That report works fine, why wont this one? any ideas?
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 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 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
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)
I'm looking to serialize some NVP data into an XML blob. I plan to put a primary xml index on the column, but my question is, would putting an XSD on the column speed up any queries, or would it just ensure format? I know that with selective xml indices, you can do things like specify the datatype associated with the xpath which can further optimize retrieval.
I would like to extact data from a source system even if it has errors. Then I can transform it and handle the errors in the appropriate manner. Are there any loosely-typed Data Flow Destinations?
<DetailRows> <DetailRow> <MonthNumber></MonthNumber> <Amount></Amount> </DetailRow> </DetailRows>If my variable contains following xml document as un-typed xml
[Code] ....
However, if I use a typed xml variable that is based on above schema, I cannot use OPENXML. What is the correct way of achieving same result with a typed xml doc? I am using SS2K5.
I have a report with multiple datasets, the first of which pulls in data based on user entered parameters (sales date range and property use codes). Dataset1 pulls property id's and other sales data from a table (2014_COST) based on the user's parameters. I have set up another table (AUDITS) that I would like to use in dataset6. This table has 3 columns (Property ID's, Sales Price and Sales Date). I would like for dataset6 to pull the Property ID's that are NOT contained in the results from dataset1. In other words, I'd like the results of dataset6 to show me the property id's that are contained in the AUDITS table but which are not being pulled into dataset1. Both tables are in the same database.
I have a small number of rows in a dataset, Table 1. There is a CLOB on a large dataset, Table 2. They join on a PK. I would like to retrieve this CLOB and add it to the data flow for Table1. In short I want to emulate the following:
Table 1: Small table without CLOB, 10 rows. Table 2: Large table with CLOB, 10,000,000 rows
select CLOB from table2 where pk = (select pk from table1)
I want this to return the CLOBs for the small number of rows in Table 1. The PK is indexed obviously so it should be a fast look up.
Table 1 and Table 2 live on different Oracle databases. How do I perform this operation efficiently in SSIS? It seems the Lookup and Merge Join wont do this.
