our c# application uses SqlDataAdapter to fetch data from the DB to present in a report. For some reason the SqlDataAdapter.Fill method is throwing below SqlException when the BUILTIN/Administrators language is British English. When it is English, it is working fine. I debugged my C# code but didn't get a clue why this is happening. Can some one help me overcome this exception?

I'm having an issue when I try to scaffold from my database. I keep getting the same error and I've traid everything. I enabled the TCP/IP port MYSQLEXPRESS, I reestarted de service, I tried changing the connection string on the scaffolding comand...
Here is the error I keep getting:

My database is located in an external server and I have connected to it by adding a linked server on Microsoft SQL Management Studio:
Here is the command I have been trying on the package manager console:
Scaffold-DbContext "Data Source=82.223.2.171,1433;Initial Catalog=db_crijoya;User ID=user;Password=****” Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models
Scaffold-DbContext "Server=82.223.2.171;Database=db;User Id=user;Password=****" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models
Scaffold-DbContext "Server=DESKTOP-M50KV5N\SQLEXPRESS;Database=db_crijoya;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models
Scaffold-DbContext "Server=CRISOFT;Database=db_crijoya;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models
I don't know how to solve it. I can connect properly to the server but I the scaffold command isn't working... Please help
If someone is having the same issue I just solved it.
I have my database in mysql server not sql. I was using on my command the package Microsoft.EntityFrameworkCore.SqlServer so It wouldn't do the scaffolding. I installed MySql.Data.EntityFrameworkCore, although it has fallen into disuse and tried this command:
Scaffold-DbContext "server=82.223.2.171;port=3306;user=user;password=****;database=db" MySql.Data.EntityFrameworkCore -OutputDir Models -f
This error is odd because I can connect to my server, however during normal use of my application I occasionally will get this error for 15 minutes. Eventually , thing will go back to normal. Shortly after that, the error begin to appear again. I have read many post that claim the issue is with the connectionstring and username/password. However, since I can connect to it sometimes, it cannot be my username and password. Is it possible that my application does not close streams and thus creating a bottleneck? I really have no idea.

The problem was I was not closing my socket connections.
I have written an OData service with an EF4 model. It's currently fully functional and deployed on at least 30 different servers. The error is occuring on one of those servers but only periodically.
The server is configured and working.
At some random point it starts responding with 500 internal server errors.
The errors aren't being handled by the HandleException method that is implemented in the service.
The exception is instead dumping straight into the Windows EventLog under Application as a warning from ASP.NET 4.0.
The contents of the warning indicate that the problem is caused by the underlying provider failing on open (I'll post the full exception details at the end of the question).
When the errors are occuring I start up SQL Server Management Studio and can connect to the database without problem.
The solution to get the service working again is to simply recycle the application pool in IIS, but this is happening 2 or 3 times a week and is causing my client grief. Can anyone point me in the right direction as to what might be causing this? The server is possibly the most underpowered system running the service and I've recommended a RAM increase as a starting point to potentially solve the problem but I'm flying blind here.

I am trying to script data of a table.
If I use windows authentication (Integrated Security=true), code works.
If I switch to sql authentication with existing user and password, it fails trying to access returned scripts enumerable. The user is an SQL login and admin.
Simplified version of code is here:
//string connectionString = "Data Source=myserver; Initial Catalog=mydb; Integrated Security=True";
string connectionString = "Data Source=myserver; Initial Catalog=mydb; Integrated Security=False; User ID=user1; Password=1234;";
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
ServerConnection serverConnection = new ServerConnection(connection);
Server server = new Server(serverConnection);
Database database = server.Databases["mydb"];
Collection<SqlSmoObject> tables = new Collection<SqlSmoObject>();
tables.Add(database.Tables["mytable"]);
Scripter scripter = new Scripter(server);
scripter.Options.ScriptData = true;
scripter.Options.ScriptSchema = false;
var scripts = scripter.EnumScript(tables.ToArray());
Collection<string> coll = new Collection<string>();
foreach (var item in scripts) // error is here
{
coll.Add(item);
}
}
Sometimes it fails with this exception:
System.Data.SqlClient.SqlException occurred

Any idea, why that happens?
Looks like a Scripter bug.
Scripter probably closes existing connection and reopens another, using ConnectionString property of the original connection. Of course, if security info is not persisted, that connection string does not have password information.
So the workaround is to create a connection with security info persisted:
string connectionString = "Data Source=myserver; Initial Catalog=mydb; Integrated Security=False; User ID=user1; Password=1234; Persist Security Info=True;";
// etc.
