You cannot use the AttachDbFileName= approach and then use a server-based command like backup database....
If you want to back up your SQL Server database, it has to be attached to the server, and you need to connect to the server and issue that command:
// Connect to "master" database
string con = #"server=.\SQLEXPRESS;database=master;Integrated Security=True;";
SqlConnection connect = new SqlConnection(con);
SqlCommand ommand = new SqlCommand(#"backup database Garment to disk = N'E:\Garment.bak' with init,stats=10", connect);
connect.Open();
command.ExecuteNonQuery();
connect.Close();
You are missing a backslash E:Garment.bak should be E:\Garment.bak
command = new SqlCommand(#"backup database Garment.mdf to disk ='E:\Garment.bak' with init,stats=10", connect);

I have the following function:
Public Function OleDBCSVToDataTable(directory As String, tableName As String, fileName As String, Optional start As Long = 0) As DataTable
Dim CnStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & directory & ";Extended Properties='Excel 8.0;HDR=YES'"
Dim dt As DataTable = GetTableSchema(tableName)
Using Adp As New OleDbDataAdapter("select * from [" & fileName & "]", CnStr)
Adp.Fill(start, 1000, dt)
End Using
Return dt
End Function
The function is designed to read a CSV into a data table using OLEDB for import into SQL, however I am receiving this error:
"The Microsoft Access database engine cannot open or write to the file
'C:\TEST'. It is already opened exclusively by another user, or you
need permission to view and write its data."
I have attempted this solution. All permissions have been granted (permissions are Full Control across users):
I have seen this solution as well, however, the proposed options other than OLEDB are solutions that don't seem to work with CSV. Besides, I imagine there are native libraries.
I am open to suggestions for better ways to accomplish this, however, based on requirements - large CSVs, data validation - this appears to be the best, assuming I am able to get it working.
How about importing the CSV file into a DataGridView, and then exporting from that object into MS Access?

I have built a repository for my realtime dashboard with 1 SqlCommand and 1 SqlConnection. My intent is to add more SQL commands to my existing code.
However, the problem is the return statement inside the SqlCommand which disables any other SqlCommand afterwards.
Can anyone help me to make this code below work.
This is the full code:
using MVCRealtime;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
namespace MVCRealtime
{
public class LocationInfoRepository
{
public IEnumerable<LocationInfo> GetData()
{
using (var connection = new SqlConnection(ConfigurationManager.ConnectionStrings["Database"].ConnectionString))
{
connection.Open();
using (SqlCommand command = new SqlCommand(#"SELECT ...", connection))
{
command.Notification = null;
SqlDependency dependency = new SqlDependency(command);
dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
if (connection.State == ConnectionState.Closed)
{
connection.Open();
}
using (var reader = command.ExecuteReader())
{
return reader.Cast<IDataRecord>().Select(x => new LocationInfo()
{
Names = x.GetString(0),
Values = Math.Round(x.GetDouble(1), 2).ToString("#,##0.00"),
ValuesDouble = x.GetDouble(1)
}).ToList();
}
}
using (SqlCommand command2 = new SqlCommand(#"SELECT... ", connection))
{
command2.Notification = null;
SqlDependency dependency = new SqlDependency(command2);
dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
if (connection.State == ConnectionState.Closed)
{
connection.Open();
}
using (var reader = command2.ExecuteReader())
{
return reader.Cast<IDataRecord>().Select(x => new LocationInfo()
{
Names2 = x.GetString(0),
Values2 = Math.Round(x.GetDouble(1), 2).ToString("#,##0.00"),
ValuesDouble2 = x.GetDouble(1)
}).ToList();
}
}
}
}
private void dependency_OnChange(object sender, SqlNotificationEventArgs e)
{
MyHub.Show();
}
}
}
This part is what i need help with(remove return):
return reader.Cast<IDataRecord>()
.Select(x => new LocationInfo()
{
Names = x.GetString(0),
Values = Math.Round(x.GetDouble(1), 2).ToString("#,##0.00"),
ValuesDouble = x.GetDouble(1)
}).ToList();
}
I just don't know how to use the
return reader.Cast<IDataRecord>().Select(x => new LocationInfo()
without the return

I think I have a fairly simple question. I just need to know how to export fields from a table in an sql database using either asp.net or C#? Anyway to do this would be good.
I suppose I am looking for something like this, but perhaps simpler:
Export values from SQL Server to txt file
Whatever the case, I am trying to get values from a database to a .txt, like by pressing a button in asp.net or C#, based on criteria (like between certain dates, from a date field, or starting at a certain date with a certain user, and exporting a certain number of them). Any suggestions would help.
If I used the following code, what would I need to change so that if I wanted to select a certain column, like Note, in the database, and Date column, what would I need to do?

conn.Open();
SqlDataAdapter da = new SqlDataAdapter("select * from tblUsers", conn);
DataSet ds = new DataSet();
da.Fill(ds);
ExportToText(ds.Tables[0], "DataTable");
}
protected void ExportToText(DataTable dataTable, string fileName)
{
HttpContext context = HttpContext.Current;
context.Response.Clear();
foreach (DataColumn column in dataTable.Columns)
{
context.Response.Write(column.ColumnName + ",");
}
context.Response.Write(Environment.NewLine);
foreach (DataRow row in dataTable.Rows)
{
for (int i = 0; i < dataTable.Columns.Count; i++)
{
context.Response.Write(row[i].ToString() + ",");
}
context.Response.Write(Environment.NewLine);
}
context.Response.ContentType = "text/csv";
context.Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName + ".txt");
context.Response.End();
}
}

You can enable sync framework tracing in verbose mode to trace the synchronization. Likewise, did you forget to set the sync direction?
