In my application I want to retrieve blind_copy_recipients
from system table 'sysmail_mailitems' from database 'MSDB' in SQL Server 2012. I am using Entity Framework in a C# web application to query databases. I created a class for sysmail_mailitems
and method to read data from it. But it actually created a new table outside of system tables with this name. My goal is not to create a table but just to read from existing table. Can anyone please guide me on how could I do it?
Code:
public class sysmail_mailitem
{
[Key]
public Int32 mailitem_id { get; set; }
public Int32 profile_id { get; set; }
public String recipients { get; set; }
public String copy_recipients { get; set; }
public String blind_copy_recipients { get; set; }
public String subject { get; set; }
public String from_address { get; set; }
public String reply_to { get; set; }
public String body { get; set; }
public String body_format { get; set; }
public String importance { get; set; }
public String sensitivity { get; set; }
public String file_attachments { get; set; }
public String attachment_encoding { get; set; }
public String query { get; set; }
public String execute_query_database { get; set; }
public Boolean? attach_query_result_as_file { get; set; }
public Boolean? query_result_header { get; set; }
public Int32? query_result_width { get; set; }
public String query_result_separator { get; set; }
public Boolean? exclude_query_output { get; set; }
public Boolean? append_query_error { get; set; }
public DateTime send_request_date { get; set; }
public String send_request_user { get; set; }
public Int32? sent_account_id { get; set; }
public Byte? sent_status { get; set; }
public DateTime? sent_date { get; set; }
public DateTime last_mod_date { get; set; }
public String last_mod_user { get; set; }
}
public String GetMailRecipients(Int32 mailItemId)
{
using(MSDBContext _db = new MSDBContext())
{
var query = (from mailItems in _db.MailItems
where mailItems.mailitem_id == mailItemId
select mailItems).FirstOrDefault();
try
{
return query.blind_copy_recipients;
}
catch (NullReferenceException) { }
return "N/A";
}
}
public class MSDBContext : DbContext
{
public MSDBContext() : base("msdb") { }
public DbSet<sysmail_mailitem> MailItems { get; set; }
}
In the end I came up with executing raw sql command using ExecuteStoreQuery to retrieve data from MSDB.
Code:
public String GetMailRecipients(Int32 mailItemId)
{
using(context _db = new context())
{
var obj = ((IObjectContextAdapter)_db).ObjectContext;
return obj.ExecuteStoreQuery<String>("SELECT blind_copy_recipients FROM msdb.dbo.sysmail_mailitems WHERE mailitem_id = {0}", mailItemId).FirstOrDefault();
}
}
