I am constantly getting EntityCommandExecutionException while executing simple query.
The query occurs in context of transaction and this is usually happens when there are many threads locking some of the database tables.
I use serialized lock and have a retry pattern, although retries work when deadlock occur i cant figure out how to handle this error or why it could be thrown.

I have the following query:
var trains = queryableTrains.Select(t => new TrainDto
{
Id = t.Id,
Prefix = t.Prefix,
Color = t.Color,
PlannedMovements = t.TrainMovementPlans
.Where(p => trackCircuitIds.Contains(p.TrackCircuitId) && p.TimeStamp >= start && p.TimeStamp <= end)
.Select(p => new TrainMovementDto
{
SgfId = null,
Prefix = t.Prefix,
BlockSectionId = p.TrackCircuit.TrackCircuitGroupId ?? p.TrackCircuitId,
Timestamp = p.TimeStamp,
IsExit = false
})
.GroupBy(o => o.BlockSectionId)
.Select(o => o.First())
//.OrderBy(d => d.Timestamp)
.ToList(),
// ...
It's a lot to code to share everything so I will share the concept hoping it helps.
Basically my data model is as follows:
Train has several PlannedMovements
I want to use GroupBy to remove "duplicates", i.e., movements that has the same BlockSectionId (after the projection).
When I run the above code, even with the OrderBy commented, I get the following exception:

If I remove the GroupBy altogether it works (but I have duplicated data).
Am I doing something wrong? Why is it generating duplicate order by's? Why is it generating Order By at all? Does Group By translates to an order by?
More strange, this happened to a collegue. In my database this was working just fine. I asked her to make a dump for me to debug. In both cases we have no data on the TrainMovementPlanned table...
This is the insert query which is causing error :
public int Insert(User obj){
string query = "INSERT IGNORE INTO tblUser(Name,Photo,Email,Password,Branch,Phone,Address,Authority,Recover_Email,Facebook_ID) values(#name,#photo,#email,#pass,#branch,#phone,#addr,#auth,#re,#fbID) ";

AFAIK, you can not use INSERT IGNORE into SQL SERVER. If you are on SQL SERVER 2008 onwards you can use MERGE to do an INSERT if row does not exist, or an UPDATE. e.g.
MERGE
INTO tmp_final dv
USING tmp_holding_DataValue t
ON t.dateStamp = dv.dateStamp
AND t.itemId = dv.itemId
WHEN NOT MATCHED THEN
INSERT (dateStamp, itemId, value)
VALUES (dateStamp, itemId, value)
Edit: It is clear that you are executing against SQL Server because SQL Server client specific types and methods appear in your stack trace.
Based on comments to the question and answers:
You have got Microsoft's SQL Server RDBMS mixed up with Oracle's MySQL RDBMS.
You need to use T-SQL (Microsoft's SQL dialect) when using SQL Server.
You need to use MySQL's SQL dialect when using MySQL.
While common code to use both can be written, it is significantly more complicated (eg. you need to use the common types (like DbCommand) for most code generating the right concrete types with some form of factory layer).
Either use one RDBMS consistently (the easier option) or build the infrastructure (including restricting yourself to the common parts of the SQL dialects) to work across RDBMSs.
So I am literally a new DBA and my machine has not been properly setup yet so every time someone sends in a request for an unknown error I am in charge of searching google for answers (hopefully changes by next week! sigh). So after searching on the internet for the past 2 hours I have yet to know what is causing the error that one of the guy sent to me. We are running sql server 2012 and we’re on patch level SP2/CU2.
The error message is

This is probably an error in the SQL that is being executed - the contents of the SQL variable. Can you post this please?
I am trying to solve an issue when using a Castle ActiveRecord TransactionScope which is rolled back.
After the rollback, I am unable to query the Dog table. The "Dog.FindFirst()" line fails with "Could not perform SlicedFindAll for Dog", because it cannot insert dogMissingName.
using (new SessionScope())
{
try
{
var trans = new TransactionScope(TransactionMode.New, OnDispose.Commit);
try
{
var dog = new Dog
{
Name = "Snowy"
};
dog.Save();
var dogMissingName = new Dog();
dogMissingName.Save();
}
catch (Exception)
{
trans.VoteRollBack();
throw;
}
finally
{
trans.Dispose();
}
}
catch (Exception ex)
{
var dogFromDatabase = Dog.FindFirst();
Console.WriteLine("A dog: " + dogFromDatabase.Name);
}
}
Stacktrace is as follows:
Castle.ActiveRecord.Framework.ActiveRecordException: Could not perform SlicedFindAll for Dog ---> NHibernate.Exceptions.GenericADOException: could not insert: [Mvno.Dal.Dog#219e86fa-1081-490a-92d1-9d480171fcfd][SQL: INSERT INTO Dog (Name, Id) VALUES (?, ?)] ---> System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'Name', table 'Dog'; column does not allow nulls. INSERT fails.

If you look at the stack trace, you'll realize that the invalid dogMissingName record is still hanging around in the session's batched insertion buffer, even after the first attempt to perform the insertion failed. Calling Dog.FindFirst() later in the same session re-triggers an internal Flush() (which attempts once again the failed insert.)
From section 9.6 of the documentation:
From time to time the ISession will
execute the SQL statements needed to
synchronize the ADO.NET connection's
state with the state of objects held
in memory. This process, flush, occurs
by default at the following points
from some invocations of Find() or Enumerable()
from NHibernate.ITransaction.Commit()
from ISession.Flush()
Additionally, from section 9.7.2 of the documentation:
If you rollback the transaction you should immediately close and discard the current session
to ensure that NHibernate's internal state is consistent.
Simply moving using (new SessionScope()) inside the outermost try/catch may be a viable workaround (the initial insertion will fail, raise an exception which will take you out of the SessionScope, likely triggering a second failure on the same insert, failure which you finally catch -- also see "data is not flushed on SessionScope.Flush()" in com.googlegroups.castle-project-users.).
Alternatively, if you don't want to close the session, you should be able to simply change the session default flush behaviour (see the FlushMode class) so that it never flushes unless Flush() is called explicitly (e.g. before committing.) Note that managing flushing in this way will get complex and error-prone very quickly, though.
The key is right on Vlad's answer:
If you rollback the transaction you
should immediately close and discard
the current session to ensure that
NHibernate's internal state is
consistent.
After you understand and apply that, your code should then look like this:
try
{
using (new SessionScope())
using (var trans = new TransactionScope(TransactionMode.New, OnDispose.Commit))
{
try
{
var dog = new Dog { Name = "Snowy" };
dog.Save();
var dogMissingName = new Dog();
dogMissingName.Save();
}
catch (Exception)
{
trans.VoteRollBack();
throw;
}
}
}
catch (Exception ex)
{
using (new SessionScope())
{
var dogFromDatabase = Dog.FindFirst();
Console.WriteLine("A dog: " + dogFromDatabase.Name);
}
}
