see the new parts in my turorial series (Widgets Inc Project) on my website.Hope it helps youFREE DEVELOPER TOOLS, CODE & PROJECTS at www.srsoft.us Database Code Generator and Tutorial Friday, December I hadenlarged the Length of a few columns ina particularSQL 2008 table. However, theMaxLength in the TableAdapter properties didnt get updated, so I thought I had a completly different problem to what was really the problem - Without your post I would have All I did delete the table adapter and recreated it and solved the problem. http://ermcenter.com/failed-to/failed-to-enable-constraints-tableadapter.html

Just regular binding data.When I run query in query builder it is executed successfully at the point when we create dataset. Aug 09, 2008 10:03 PM|oradev-ming|LINK After some inverstigation I figured that is because the query (SP)I added to the tableadapter has a few JOINs which has additional columns compare to the When the filter criteria generated rows which exceeded the max length it gave me an error.

Aug 28, 2009 03:22 PM|Chaka44|LINK This may seem like generic advice; However it helped me to find a stored procedure was not returning the same dataset as the data-table defined.

Oct 20, 2011 04:44 AM|mrisho|LINK Open the dataset, right click inside the dataset ( not dataAdapter ), then select properties on the shot cut menu. I found few solutions but these does not work for me. A specific error message would save all of this effort. http://stackoverflow.com/questions/8657294/failed-to-enable-constraints dt.GetErrors()[0] {System.Data.DataRow} HasErrors: true ItemArray: {object[10]} RowError: "Column 'eval' does not allow DBNull.Value." So I solve my problem by replacing e.eval to ,NVL (e.eval,'') eval.and this solves my problem.

One or more rows contain values violating non-null, thanks for the reply If you don't want to enforce constraints then don't use a DataTable with constraints in the first place. I think it might be because I'm not actually returning FROM a table and just returning a string? Browse other questions tagged c# sql or ask your own question. One or more rows contain values violating non-null, unique, or foreign-key constraints.

Thanks again Friday, May 04, 2007 8:09 PM 0 Sign in to vote I keep getting this error whenever I FILL (and it returns just one row) even though the data Basically, the problem is because the tableadapter fills my dataset with data from the entire table in the database. I usually do two things - run thestored procedure in SQL Servermanagement studio and manually compare the output with the XSD schema. - When the above provides no immediate clues I This means that every table column created with the constraint of "not null" or "foreign key" must also be present in the result of your SQL statement or stored procedure.

Solution: Check all the MaxLength property of the columns in your DataTable. list of files based on permission I never succeed in thickening sauces with pasta water. dataset.TableA.Clear(); dataset.EnforceConstraints = false; dataAdapter1.daTableA.Fill(dataset, TableA"); The fill method might be slightly different for you.

Does anyone know what that blue thing is? My MSDN Developer Code Samples... However, for many of us, the "unique primary key" solution is a false diversion. have a peek here Ok now our RDLC report also configured.

Failed to enable constraints. So when the resultset try to retrieve a record more than length of 37 then report generates the error: Failed to enable constraints. Unless you add them yourself, they can only be created when DataTable and DataSet schema is generated automatically, by the Data Source or the like. One or more rows contain values violating non-null, unique, or foreign-key constraints.

Worked for me. but none of the previous solutions works for me.. it helped me to resolve a gr8 headache... Idiocy!

Helped a ton. Tuesday, January 09, 2007 8:39 PM 0 Sign in to vote Searching for two ours and your tip made the solution. The error went away when I set this property to False. ‹ Previous Thread|Next Thread › This site is managed for Microsoft by Neudesic, LLC. | © 2017 Microsoft.
