Closed 5 years ago.
I just want to know what is the meaning of this error? The INSERT statement conflicted with the FOREIGN KEY constraint "FK__thumbnail__instr__160F4887". The conflict occurred in database "MusicStoreDB", table "dbo.instrumentItem", column 'instrumentId'.
The statement has been terminated.
Here is the stack trace:

It means that you are trying to insert a row in instrumentItem table and the value that you are assigning to the instrumentId column, is invalid. There is a foreign key relationship between this table and another table in the database and the value of instrumentId should exist in the other table, but it doesn't.

there are some record when try to do update savechanges it fail ?
I check one success and fail DB record both look like same ?
Is there anything i can catch from this ex message ?
Stackers, I am getting an exception Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction on the production server for my web application (Asp.Net Web Form with Telerik Controls + C# + SQL Database).
I have added the stack trace of the exception in the last.
The strange thing is the application is not using transactions for some of the processes where this exception occurred. And we have not implemented any kind of distributed system concepts.
Here is some information about the server where applications are hosted-
More than one instance of the same application are hosted on the same server. Means we have different clients and the same web application is hosted for each client on different public domain URLs.
Web Applications and their dedicated SQL database are on the same server.
All hosted web applications are using the same SQL user id to connect to their database.
Each application uses its own dedicated App Pool in the IIS.
Can anyone help in this to figure out why I am getting this exception?
Any kind of help is appreciated :)

Occasionally, while debugging some older application code, we receive an exception.
This is the offending line of code:
XMLReferenceSequence lastXml = (from xml in _entities.XMLReferenceSequences
where xml.ServiceId == aService.Id
where xml.SourceTypeId == ETrainsSourceType.SOURCE_RAIL_XML
orderby xml.ReferenceDateTime descending
select xml).FirstOrDefault();
It should be noted that the code does work most of the time and this does happen rarely.
Any thoughts on how to solve this issue would be appreciated. Was considering reformatting the code to perhaps do a ToList() first before FirstOrDefault()?

Your error message indicates your method failed to execute in time.
System.Data.SqlClient.SqlException: Execution Timeout Expired. The
timeout period elapsed prior to completion of the operation or the
server is not responding
Sql Connections connection have a CommandTimeout property, which by default is 30 seconds. If your query doesn't complete within this time the exception above is thrown. You can increase this value in your connection string if you know that you have a long running query that might exceed this limit. See this: https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.commandtimeout(v=vs.110).aspx
Ideally, you can fix this problem by to determining whether it is your query or another query that is causing the problem. If it is your query, optimizing the data with a maintenance plan and/or creating indexes can speed up the query.
Another potential hazard is a long running query that locks one of the tables you are pulling data from. If this is the case you can performing a query that require the data you are pulling doesn't have a lock on it. This post shows how to do this entity framework. Entity Framework with NOLOCK
I have installed SQL Server 2014 on my new PC yesterday, it was working until I restarted my PC, now I am getting this error.
I have started / restarted SQL Server services etc..
I can still connect from Management Studio.
When adding EF model to my asp.net project, it can list databases and get tables to generate EF model, but I can't do anything with the database because of this timeout exception, database is almost empty (only 1 table with 1 user in) and I am executing simple queries (like select, add)
using(var db = new TestEntities())
{
var _user = db.Users.FirstOrDefault(); // timeout exception

The sql server instance is closed therefore server couldn't respond.
Could it be that the TCP/IP protocol is not enabled? Check SQL Server Configuration Manager.
It could also be that it's not accepting remote connections. For that, you need to check with SQL Server Management Studio, server properties, Connections.
Update-Database command was giving this error:
There is already an object named 'StationsArrangeds' in the database.
So I deleted this table and now I'm getting this exception while trying to update database.
Using StartUp project 'MetroTrain'. Using NuGet project 'MetroTrain'.
Specify the '-Verbose' flag to view the SQL statements being applied
to the target database.

I've gone through forums no solution found.
Manually deleting tables in code first causes EF to lose track of your model changes.
You can reset code first migrations by deleting migration history table and re-enable migration.
This is mostly because your database Migration table ("__MigrationHistory") is not sync with your Migration
you can change your Database Name in default connection string and create new database.
after create new database compare it with existing Database menualy and sync "__MigrationHistory" from new database to existing for later Migrate
