ADO.Net Entity framework, Fatal error encountered during data read

问题

I am getting the following error while using MySql with Entity framework. I have set the default connection timeout to 300000 on the connection string of EntityConnectionStringBuilder. How to resolve this in Entity framework?

    Unhandled Exception: System.Data.EntityCommandExecutionException: An    
    error occurred while reading from the store provider's data reader. See the  
    inner exception for details. ---> MySql.Data.MySqlClient.MySqlException: Fatal 
    error encountered during data read. ---> MySql.Data.MySqlClient.MySqlException: 
    Reading from the stream has failed. ---> System.IO.EndOfStreamException: Attempted 
    to read past the end of the stream.

Update: How can we set net_read_timeout for ado.net entity framework?

回答1:

Like this

data.Database.ExecuteSqlCommand("set net_write_timeout=99999; set net_read_timeout=99999");

回答2:

what does the inner exception say?

Unhandled Exception: System.Data.EntityCommandExecutionException does not point to a timeout error, it could be something as simple as an int that needs to be nullable that is used in your EF query.

Could you give the query to?

Cheers
