How can I work around? up vote 0 down vote favorite Issue I am refactoring a project written datatable geterrors by a developer in C# .NET 4.5 project which contains a dataset.xsd. I was asked to increase the efficiency of the project. Basically, the problem is because the tableadapter fills my dataset with data from the entire table in the database. This is several million rows of data. Problem I had a line that is basically doing this. this.customersTableAdapter.Fill(this.derpDataset.Customers); So I decided to do something like this (not wanting to change the .xsd): //This references a class written in order to get the database manually instead of using the .xsd SqlConnection sqlConnection = DB_Connection.OpenDatabase(); SqlCommand sqlCommand = new SqlCommand("SELECT * FROM COMDB WHERE ID = " + ID.ToString() + ";", sqlConnection); this.customersTableAdapter.Adapter.SelectCommand = sqlCommand; this.customersTableAdapter.Adapter.Fill(this.derpDataset.Customers); Code Basically, the .xsd has a bunch of auto generated stuff, but I just needed a way step around it and fill with a much more optimized query.

One or more rows contain values violating non-null, unique, or foreign key constraints up vote 2 down vote favorite hi i have a very simple webform i have a button and a gridview on this form and a dataset that contains linked tables bill, docket, docket_bill etc. On Button click i use the following code protected void button_click(object sender, EventArgs e) { billTableAdapter http://stackoverflow.com/questions/6014365/asp-net-dataset-getdataby-failed-to-enable-constraints-one-or-more-rows-contain Billta = new billTableAdapter(); gridview1.datasource = Billta.getTop20Bills(); gridview1.databind()' } Now when i click on the button, i get the following error "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign key constraints" However, when i change the code to protected void button_click(object sender, EventArgs e) { billTableAdapter Billta = new billTableAdapter(); gridview1.datasource = Billta.getdata(); gridview1.databind()' } It works fine. billTa.getData() gets all the rows from the dataset and shows up in the gridview. but when i add a query and select only few columns, then it gives me the aforementioned error. Any idea what is wrong here?

For example, loading child records before loading related parent records can violate a constraint and cause an error. As soon as you load a child record, the constraint checks for the related parent record and raises an error. If there were no mechanism to allow temporary constraint suspension, an error would be raised every time you tried to load a record into the child table. Another way to suspend all constraints in a dataset is with the BeginEdit, and EndEd
values violating non-null, unique, or foreign-key constraints." How to: Troubleshoot "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." MGR October 13, 2011 2 comments Working with DataSets, you might face this error message that will keep you from using code that you knew was working just fine. There may be many reasons for this error message to pop up on your screen, and most of them have been talked about extensively in other blog posts. A search online will give you more than a handful of reasons why you might get this message. However, it'd be interesting to discuss why this error appears when you execute some SQL Query when, if you were to execture the same SQL Query inside your SQL Server, it would work just fine. This has to do with the fact that the .xsd in your visual studio is built once. When you first configure your Table Adapters and Data Tables. Once they have been configured, they're strongly typed and ready to be used. Unfortunately, they do not keep a live connection to the actual database. What that means is that your .xsd and your SQL DB, more often than not, will be out of sync if/when you decide to change something in your DB. You need to make sure that the .xsd represents your SQL correctly. In my case, I had erased a column from a table in my SQL DB and although I did go back to the .xsd and re-configured the affected Data Table, I failed to notice that, although the SQL Table had four columns, the .xsd Data Table was still looking for a fifth one. You can click on the left side of the columns that make up your .xsd Data Table to select the column and then easily delete it with a press of the delete key. That should fix it. Another solution found online includes the checking of the column properties inside your .xsd file to make sure that they match the column properties of your actual SQL DB table column.
