Good afternoon,
Im having some trouble writing a simple script using SMO objects in C# to validate if an object exists and then create it. This code is within a Script Task Component in SSIS. The code executes successfully, however the new database does not show up on my local instance. Any help would be greatly appreciated.
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;
using System.Collections;
using System.Data.SqlClient;
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;
public void Main()
{
//String DBName = Dts.Variables["TmpViewDBName"].Value.ToString();
//String Instance = Dts.Variables["TmpViewDBInstance"].Value.ToString();
String DBName = "localhost";
String Instance = "TmpViewDB";
Server TmpViewServer = new Server(Instance);
//Windows Auth
TmpViewServer.ConnectionContext.LoginSecure = true;
TmpViewServer.ConnectionContext.Connect();
if (TmpViewServer.Databases[DBName] != null)
{
TmpViewServer.Databases[DBName].Drop();
}
Database TmpViewDB = new Database(TmpViewServer, DBName);
if (TmpViewServer.ConnectionContext.IsOpen)
TmpViewServer.ConnectionContext.Disconnect();
Dts.TaskResult = (int)ScriptResults.Success;
}
I believe you need to add a line to actually create the object. As it stands now, you've only instantiated the object but never actually made the call to the database to create the remote object.
Database TmpViewDB = new Database(TmpViewServer, DBName);
TmpViewDB.Create();

I'm trying to send an email with Azure and SendGrid. I have it all set up (I think) and my code is as per below, but the 'DeliverAsync()' method is not working and there is no 'Deliver()' option available.
Here are my using statements:
using System;
using System.Web;
using System.Web.UI;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Net;
using System.Net.Mail;
using SendGrid;
Here is my code: 'transportWeb.DeliverAsync(myMessage)' is showing as plain black text.
// Create the email object first, then add the properties.
var myMessage = new SendGridMessage();
myMessage.AddTo("d#gmail.com");
myMessage.From = new MailAddress("d#gmail.com", "John Smith");
myMessage.Subject = "Testing the SendGrid Library";
myMessage.Text = "Hello World!";
var apiKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
// create a Web transport, using API Key
var transportWeb = new Web(apiKey);
// Send the email, which returns an awaitable task.
transportWeb.DeliverAsync(myMessage);
I'm hoping someone has seen this before and knows the solution. There are a lot of similar problems online, but none I've found with a fix to this. I am using SendGrid v6.3.4. I have tried reverting to v6.3.3 but it didnt help. My stats in SendGrid show zero for everything, no emails sent, no requests, no bounces etc.
UPDATE:
I have tried creating a new Email class to remove any clutter and make this clearer, the 'DeliverAsync' method is still not being recognized after transportWeb.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Net;
using System.Net.Mail;
using SendGrid;
using System.Threading.Tasks;
namespace CPWebsite
{
public class Email
{
static async void Main()
{
try
{
// Create the email object first, then add the properties.
var myMessage = new SendGridMessage();
myMessage.AddTo("d#gmail.com");
myMessage.From = new MailAddress("d#gmail.com", "John Smith");
myMessage.Subject = "Testing the SendGrid Library";
myMessage.Text = "Hello World!";
var apiKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
// create a Web transport, using API Key
var transportWeb = new Web(apiKey);
// Send the email, which returns an awaitable task.
await transportWeb.DeliverAsync(myMessage);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
}
I have also tried changing var myMessage = new SendGridMessage(); to SendGridMessage myMessage = new SendGridMessage(); but no luck. Only the following using statements are showing as necessary.
using System;
using System.Net.Mail;
using SendGrid;
Im trying anything at this point!
Is this a console app currently? You'll need to await the method otherwise the console apps main thread will complete execution and cause the worker threads to be killed before they successfully deliver the message.
Try:
await transportWeb.DeliverAsync(myMessage);
Also add the following to your using statements:
using System.Threading.Tasks;
My project (Windows Service) was essentially synchronous with respect to specific thread where SendGrid was called, and hence what I had to do to make it work is to add .Wait() after the .DeliverAsync().
And so, try:
static void Main()
and later:
transportWeb.DeliverAsync(myMessage).Wait();
There is actually a little foot-note in SendGrid documentation eluding to this technique.
Cheers.
I don't know if this has been resolved but try using myMessage.Html for the body instead of myMessage.Text. Especially if you are using html in the body. I have pretty much the same setup and my code works fine.
I am a newbie at JSON programming. Most of my experience is in C# and some in XML and Javascript. So I am a bit lost. I will attempt to be as specific as possible.
I have written a windows console application that runs via the task scheduler. Basically the windows application is supposed to take the API from a site that is managed by an outside company but the information is owned by my company and put the information within a SQL table. The API is pretty standard and written in JSON.
I am successful in parsing the JSON language and (for example) displaying it in a command prompt but I need to be able to parse the language and place it into an SQL table. I have read up on SQL injection attacks and I feel fairly confident that we have covered our bases here. So the problem lies in the fact that it does not update the table when the application is run via the scheduler or without the scheduler.
I have included a little bit of the JSON language below along with the language for my console application.
{"date":"2015-09-24","data":[{"cid":"17","rank":1},{"cid":"26","rank":1},{"cid":"80","rank":1},{"cid":"30","rank":1},{"cid":"90","rank":1},{"cid":"62","rank":1},{"cid":"147","rank":1},{"cid":"28","rank":1}"s":1,"e":null}

What am I missing to make the JSON data update my SQL table? I have scoured Google search results and I haven't found much information. Any help would be so greatly appreciated.
For the need to foreach with the correct part of the JSON object, what I mean is very simply that your variable results includes the entire JSON object, from the "date" through the "e". You need to start with the "data" object and iterate through its array or your string cid will error out on assignment, as it will be attempting to assign an array to a single value. The same goes for your JToken rank. I believe it should be this:
foreach(datum in results["data"])
{
string cid = datum["cid"];
JToken rank = datum["rank"];
/* ... */
}
In addition, your set command isn't doing anything. You need to use SET columName = " + newValue + " WHERE CID == " + cid to actually affect a change, where columnName is the column you wish to alter and newValue is your C# variable carrying the desired replacement.
It's also a best practice to include a change to an updated date field when updating via an automated process, if there is one present. Generally the convention is to have a created date and an updated date for each row in a table.
I hope this at least points you in the right direction.

As an alternative, you can send entire text to Sql Server and load it there.
Sql Server 2016 will enable you to store JSON using single command - OPENJSON. In the older versions you can use existing CLR/JSON libraries such as Json4Sql or JsonSelect.
I ran into a problem when switching from the Local Development Server to the Local IIS Server (ASP.NET MVC4) using the following Controller-Method:
public JsonResult GetJsonData(string Context, string Language)
{
using (KeyValueDBContext db = new KeyValueDBContext())
{
var entries = from u in db.KeyValues
where ((u.Context == Context) && (u.Language == Language))
select u;
return Json(entries, JsonRequestBehavior.AllowGet);
}
}
Using the local server, I received data when calling the method from Javascript without a problem. The method retrieves a collection of basically Key-Value pairs from a database repository and sends them to the client). After switching to IIS I got an Exception telling me that the dbcontext had already been disposed of (although the using clause ends after the return-statement). (NB: Visual Studio also was not able to find JSONSerializer.cs for some reason, but only when the error occurred). Switching to the following version solved the problem completely:
public JsonResult GetJsonData(string Context, string Language)
{
KeyValueDBContext db = new KeyValueDBContext();
var entries = from u in db.KeyValues
where ((u.Context == Context) && (u.Language == Language))
select u;
return Json(entries, JsonRequestBehavior.AllowGet);
}
In both cases, this was the using-block:
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using beepov4.Models; // project-models
My question: Is this an acceptable way to use dbcontext for the purpose of JSON-calls (and dropping the using-clause) or is there a particular downside or hidden problem I should be aware of?
Try reading the entries into memory with entries.ToList() before passing them to Json():
using (KeyValueDBContext db = new KeyValueDBContext())
{
var entries = from u in db.KeyValues
where ((u.Context == Context) && (u.Language == Language))
select u;
return Json(entries.ToList(), JsonRequestBehavior.AllowGet);
}
I installed a TFS2012 as a test system and doing some tests before we go productive.
This includes to define many BuildDefinitions which was a lot of work.
After the tests are successful, an new server will be installed with TFS2012 on it.
For this new server - which operates then as the productive system - i would like to restore the BuildDefinitions from the test system. But only the BuildDefinitions, not the whole TeamCollections. Because i ran test checkins and i don`t want these on my productive server.
Now, is it possible to backup and restore BuildDefinitions only?
Maybe it is possible directly throught the Sql database?, but i`am a little affraid of references there, pointing on some other tables.
Best Regards, Peter Bucher
Build definitions are not source controlled. The only option is relying on the TFS database backup where can restore or view the tbl_BuildDefinition* tables in the Tfs_DefaultCollection database.
There is a user voice for this feature and also you can use TFS API to do it.
Add a vote on uservoice:
provide a way to version-control build definitions
Using TFS API
How can I copy a TFS 2010 Build Definition?
Finally i decided not to touch the database, because there are references to a lot of other tables.
I used the TFS API v11 (TFS2012) and a bit C# Code, which i fitted to my needs from this base: How can I copy a TFS 2010 Build Definition?
It copies all Build Definitions from one TFS2012 Server to another. For both servers there is the need to specifiy a TeamCollection and a TeamProject.
So, the copy-task has to be done per TeamProject.

I am trying to use Dapper for our complex queries to remove any lost overhead that was previously existing with NH.
I have the following query (note this has been considerably shrunk):
SELECT DISTINCT *
FROM tasks t
WHERE t.initials = #UserInits
Which is called via our repository as so:
taskRepo.RawExec<TaskListItemDTO>(Query,new {UserInits = "SAS"})
Our implementation of DapperExec consist as follows:
public IEnumerable<T> RawExec<T>(string SQL, object param)
{
return _session.Connection.Query<T>(SQL,param);
}
But Dapper doesn't appear to be adding the parameters to the query, and as a result, we are getting syntax errors.
Incase it helps, we are connecting over ODBC to Informix.
Thanks
Update Code Sample:
Sorry it took so long, been very busy with work! Below is a sample for MS SQL (2008) Server that should simple query the sys.all_objects (systables?) with a param value of 1 or 0 - but in this sample, as ODBC does not use named params, this won't work.
using Dapper;
using DapperSQL;
using System.Collections.Generic;
using System.Data;
using System.Data.Odbc;
namespace DapperTests
{
public class SQLEx
{
private OdbcConnection GetConnection()
{
var cnn = new OdbcConnection("DSN=ODBCSOURCE");
cnn.Open();
// wrap the connection with a profiling connection that tracks timings
return cnn;
}
public IEnumerable<object> DapperTest()
{
using (OdbcConnection conn = GetConnection())
{
return conn.Query("SELECT * FROM sys.all_objects where is_ms_shipped = ?", new { is_ms_shipped = 1 });
}
}
}
I know this is old post, just use SP instead of query, please check this link Dapper using ODBC store procedure Input parm, this using sybase odbc Sp, all odbc use same technique, I wish it works in Informix.
