I am trying to do a function to update a value in a SQL database, this is my table
This is the function
private void UpdateGanToDB(float entrada, string Id)
{
string string_entrada = entrada.ToString();
string conString = Properties.Settings.Default.LocalDataBaseConnectionString;
string command_string = "UPDATE Gan SET Ganan = #GetGan WHERE Id = #GetId";
SqlConnection connection = new SqlConnection(conString);
SqlCommand cmd = new SqlCommand(command_string, connection);
cmd.Parameters.AddWithValue("#GetGan", string_entrada);
cmd.Parameters.AddWithValue("#GetId", Id);
try
{
connection.Open();
int row = cmd.ExecuteNonQuery();
if (row > 0) {
MessageBox.Show("Upgrade successful");
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
connection.Close();
}
}
I am getting the message "upgrade successful" but when I check the database I can't see the changes. When I run the text in the command_string with known values I can see the changes but not with my function
Edit:
I added this code to the code above
int row = cmd.ExecuteNonQuery();
if (row > 0) {
SqlCommand command = new SqlCommand("SELECT * FROM Gan ", connection);
SqlDataAdapter adapter = new SqlDataAdapter(command);
System.Data.DataTable dataTable = new System.Data.DataTable();
adapter.Fill(dataTable);
MessageBox.Show(dataTable.Rows[0]["Ganan"].ToString());
}
To see if it is updating the value and I get the excepted 200 (Original value was 0) But When I close the application and see the values in the local database I see the original value 0 I don't know why the update is not saving
EDIT2:
I found another post with a work around for this problem: Can I commit changes to actual database while debugging C# in Visual Studio?
I think your code is correct and there is no problem
If you created database via Add\NewItem\Service-Base Database
I'm not sure, but I think After running your project, one copy of your original database will be included in the debug folder in your project and the update operation and also other operations run on that, not your original database
so, if you want to see a result, you should connect to that via View\ServerExplorer
meantime, after Change your Code and rebuild your Project, your debug database will be deleted and again one copy of your original database will be included in the debug folder

I'd like to build a back end system that allows me to run each report every night and then query the execution log to see if anything failed. I know you can build out subscriptions for these reports and define parameters etc but is there a way to execute each report from the ReportServer database using TSQL without building out each subscription?
I understand that your overall goal is that you want to automate this and not have to write a subscription for every report. You say you want to do it in T-SQL, but is that required to meet your overall goal?
If you can accept, say .Net, then you can use the System.Data.SqlClient.SqlConnection and related classes to query your report server catalog and fetch a listing of all your reports.
Then you can use System.Net.WebClient or similar tool to attempt to download a pdf of your report. From there you can either read your execution log, or catch the error in the .Net Code.
EDIT
Well, since you accepted the answer, and it seems you may go this route, I'll mention that if you're not familiar with .net, it may be a long path for you. Here's a few things to get you started.
Below is a c# function utilizing .Net that will query the report catalog. If safeImmediate is set to true, it will only capture reports that can be run immediately, as in there are no parameters or the defaults cover the parameters.
IEnumerable<string> GetReportPaths(
string conStr,
bool safeImmediate // as in, you can exexute the report right away without paramters
) {
using (var con = new SqlConnection(conStr))
using (var cmd = new SqlCommand()) {
cmd.Connection = con;
cmd.CommandText = #"select path from catalog where type=2";
con.Open();
if (safeImmediate)
cmd.CommandText = #"
select path
from catalog
cross apply (select
params = convert(xml, Parameter).value('count(Parameters/Parameter)', 'int'),
defaults = convert(xml, Parameter).value('count(Parameters/Parameter/DefaultValues/Value)', 'int')
) counts
where type = 2
and params = defaults
and path not like '%subreport%' -- this is not standard. Just works for my conventions
";
using (var rdr = cmd.ExecuteReader())
while (rdr.Read())
yield return rdr["path"].ToString();
}
}
The next function will download a report given proper paths passed to it:
byte[] DownloadReport (
WebClient wc,
string coreUrl,
string fullReportPath,
string parameters = "" // you won't use this but may come in handy for other uses
) {
var pathToViewer = "ReportServer/Pages/ReportViewer.aspx"; // for typical ssrs installs
var renderOptions = "&rs:Format=pdf&rs:Command=Render"; // return as pdf
var url = $#"{coreUrl}/{pathToViewer}?{fullReportPath}{parameters}{renderOptions}";
url = Uri.EscapeUriString(url); // url's don't like certain characters, fix it
return wc.DownloadData(url);
}
And this utilizes the functions above to find what's succeeding and whats not:
var sqlCon = "Server=yourReportServer; Database=ReportServer; Integrated Security=yes"; // or whatever
var ssrsSite = "http://www.yourSite.org";
using (var wc = new WebClient()) {
wc.UseDefaultCredentials = true; // or whatever
int loops = 3; // get rid of this when you're ready for prime-time
foreach(var path in GetReportPaths(sqlCon, true)) {
try {
DownloadReport(wc, ssrsSite, path);
Debug.WriteLine($"Success with: {path}");
}
catch(Exception ex) { // you might want to get more specific
Debug.WriteLine($"Failed with: {path}");
}
if (loops-- == 0)
break;
}
}
Lots to learn, but it can be very beneficial. Good luck.
I am trying to send all the table records in email body though send mail task
My flow:
I uses SQL execute task to fetch the rows from table and stored in an object
Uses for each loop container and in that I use a script task to store the rows in an EmailMessage body
I used Send mail task to send the email
I am only getting last records of the table in the message body.
Please guide me how to send all the table data at once in a message body
Actaul flow
error
I think I would take a slightly different approach and recurse the recordset directly in the script task but this looks like it would work too. I would guess that your problem is that you overwrite User::EmailMessage at every iteration. You say you get last few records but looking at your code I would think you will get 1 unless you uncomment the IF (varcollection == string.empty) in which case you might get more.
Anyway, the main offending problem is
varCollection["User::EmailMessage"].Value = header;
That resets your EmailMessage body to the header row any time it is called.
Edit: Adding as per your comment to reset message at every new shipment number. Add another package variable PrevShippingNum which will hold the previous looped number to test if it is the same or has changed. Make sure that this variable is listed as ReadWriteVariable to the script task. then modify your script to include something like this:
Dts.VariableDispenser.GetVariables(ref varCollection);
bool newMessage = (varCollection["User::PrevShippingNum"].value != varCollection["User::ShppingNum"].value) ? true : false;
if (string.IsNullOrWhiteSpace(varCollection["User::EmailMessage"].Value.ToString()) || newMessage)
{
varCollection["User::EmailMessage"].Value = string.Format("{0}........");
}
varCollection["User::EmailMessage"].Value += string.Format("{0}......");
The positive about this is you can also use your new variable as a constraint to determine when to send email task.
A different Approach:
Note pretty big edit to add new sub to take care of sending emails per ShippingNum:
Way I would proceed pass the recordset variable you are using to a script task and let it do the email message building. Just to be clear this is to replace your foreach loop! here is some code adapted from one of my solutions:
Add Reference to System.Data.DataSetExtensions
Add following namespaces:
using System.Data.OleDb;
using System.Net.Mail;
using System.Linq;
using System.Collections.Generic;
private void Main()
{
//using System.Data.OleDb;
OleDbDataAdapter oleAdapter = new OleDbDataAdapter();
DataTable dt = new DataTable();
oleAdapter.Fill(dt, Dts.Variables["User::OleDbRecordSetVar"].Value);
//build header row
string headerRow = string.Format("{0}........", "ShippingNum ....");
//get distinct shippingNums
var shippingNums = (from DataRow dr in dt.Rows
select (int)dr["ShppingNum"]).Distinct();
//Now Build the Differnt Emails
foreach (var num in shippingNums)
{
string emailBody = headerRow;
List<DataRow> emailLines = (from DataRow dr in dt.Rows
where (int)dr["ShippingNum"] == num
select dr).ToList<DataRow>();
foreach (DataRow line in emailLines)
{
emailBody += string.Format("{0}....", line["ColumnName1"].ToString(), line["ColumnName2"].ToString());
}
SendEmail(emailBody);
}
Dts.TaskResult = (int)ScriptResults.Success;
}
private void SendEmail(string messageBody)
{
//get the smtp server address from the SSIS connection manger
ConnectionManager smtpConnectionManager = Dts.Connections["Name Of SMTP Connection Manager"];
//note this is for trusted authentication if you want to use a username and password you will have to do some discovery
SmtpClient emailClient = new SmtpClient(smtpConnectionManager.Properties["SmtpServer"].GetValue(smtpConnectionManager).ToString());
MailMessage email = new MailMessage();
email.Priority = MailPriority.Normal;
email.IsBodyHtml = false; //change to true if you send html
//can hard code addresses if you desire I use variables to make it more flexible
email.From = new MailAddress(Dts.Variables["User::FromAddress"].Value.ToString());
email.To.Add(Dts.Variables["User::ToAddress"].Value.ToString());
email.Body = messageBody;
emailClient.Send(email);
}
This question has been addressed all over the web and I tried a lot of things without success. The SQL EXPRESS service is setup to accept local system account but the problem still exists.
This is my connection string:
<add name="PhoneTemplateChange" providerName="System.Data.SqlClient" connectionString="Data Source=.\SQLEXPRESS;Database=PhoneTemplateChange;Integrated Security=SSPI" />
I created a class to do database operations in the constructor I have
_connectionString = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["PhoneTemplateChange"].ConnectionString;
and a method in this class to insert data
public void AddNewChangeOrder(int operation, int targetExt)
{
using (SqlConnection con = new SqlConnection(_connectionString))
{
string sql = "INSERT into [dbo].ChangeOrder (operation, targetExt, dtrequested) VALUES (#operation, #targetExt, #dtrequested)";
using (SqlCommand cmd = new SqlCommand(sql))
{
try
{
cmd.Parameters.AddWithValue("#operation", operation);
cmd.Parameters.AddWithValue("#targetExt", targetExt);
cmd.Parameters.AddWithValue("dtrequested", DateTime.Now);
//con.CreateCommand();
con.Open();
//cmd.InitializeLifetimeService();
int rows = cmd.ExecuteNonQuery();
con.Close();
}
catch (SqlException e)
{
throw new Exception(e.Message);
}
}
}
I have played around with the connection string trying all different suggestions, also the commented code in the method above is what I tried to solve the problem. Still no luck!
I also changed the connection string I get two different exceptions this way
Database=PhoneTemplateChange
The above gives the exception in the title.
And the following gives the Exception "Cannot open Database PhoneTemplatechange.mdf requested by the login. Login failed for user 'mydomain\myusername'"
Database=PhoneTemplateChange.mdf
Any ideas?
You are missing the line of code where you specify that cmd uses con as it's connection. As a result the Command (cmd) has no connection, and con isn't associated with any command at all.
Add this line before executing:
cmd.Connection - con;
Alternatively (and better IMO) change your using statement as follows:
using (SqlCommand cmd = new SqlCommand(sql, con))
I'm automating UI tests to my Silverlight App and I'm using Visual Studio 2010 for it. Some tests required a setup to my Oracle Database.
Things i've done:
1 - A setup.sql file where I connect to my Database and perform actions on it. I had this file as an existing item to my project and I add as a Deployment on TestSettings.
Code:
CONNECT USERNAME#DATABASE,
CREATE TABLE TABLE_NAME,
EXIT
2 - A set.bat file where I call the setup.sql file. I had the path of this file on Setup and Cleanup tab on TestSetings.
Code:
sqlcmd -S MARIALISBOA -i setup.sql
3 - I wrote a TestInitilize method on my TestClass.
Code:
[TestInitialize()]
public void Initialize()
{
System.Diagnostics.Process.Start("setup.bat");
}
4 - I connected do my Database throw Visual Studio (Data -> Add New Data Source).
I run a test on Visual Studio but the class isn't created on my database.
Could anyone help me? I'm trying to solve this problem since Monday and I starting to lose my mind
While it does not solve your initial problem, a solution would be to use something similiar to this;
Do not create the table within your tests. this should be created on install of the Test Environment
Clear down the table for each test you want to do using a Helper Method within the test.
For example (Please note that this is SQL Server, use OLE DB connection or similiar);
internal static object FireSqlStatement(string sqlStatement)
{
object result = null;
using (var cn = new SqlConnection(ConfigurationManager.ConnectionStrings[connectionString].ConnectionString))
{
cn.Open();
var cmd = new SqlCommand
{
CommandText = sqlStatement,
CommandType = CommandType.Text,
Connection = cn
};
result = cmd.ExecuteScalar();
cmd.Dispose();
cn.Close();
}
return result;
}
An example of how I use this within my test;
[Test]
public void GetUserTriggers()
{
//Insert Test Record
Helper.FireSqlStatement("INSERT INTO [Users].[Triggers] (Id) VALUES (1)");
var request = new GetTriggersRequest()
{
TriggerType = TriggerType.UserTrigger
};
var response = ServiceInvoker.Invoke<IReports,
GetTriggersRequest, GetTriggersResponse>(
"Reports",
request,
(proxy, req) => proxy.GetTriggers(req));
foreach (var t in response.Triggers)
{
Console.WriteLine(t.Id.ToString());
}
Assert.NotNull(response);
Assert.NotNull(response.Triggers);
Assert.Greater(response.Triggers.Count, 0);
}
In your case, you could call;
Helper.FireSqlStatement("TRUNCATE TABLE tableName");
Any good?
I'm using Visual C#2008 Express Edition and an Express SQL database. Every time I build my solution, I get an error like the one above. Obviously the file name changes. A new file is also created every time I hit a debug point.
I have a stored proc that gets every row from a database table, it gets these rows every time the main form initialises and Adds them to a Generics list. Without inserting or deleting from the table, it gets a different number of rows each time I start my windows application. The error started happening at the same time as the weird data retrieval issue. Any ideas at all about what can cause this?
Thanks
Jose,
Sure, here's my c# method, it retrieves every row in my table, each row has an int and and Image ....
private List<ImageNumber> GetListOfKnownImagesAndNumbers()
{
//ImageNumber imNum = new ImageNumber();
SqlCommand sqlCommand = new SqlCommand();
sqlCommand.Connection = _conn;
try
{
MemoryStream ms = new MemoryStream();
sqlCommand.CommandText = "usp_GetKnownImagesAndValues";
_conn.Open();
using (IDataReader dr = sqlCommand.ExecuteReader())
{
while (dr.Read())
{
ImageNumber imNum = new ImageNumber();
imNum.Value = dr.IsDBNull(dr.GetOrdinal("ImageValue")) ? 0 : Convert.ToInt32(dr["ImageValue"]);
//Turn the bitmap into a byte array
byte[] barrImg = (byte[])dr["ImageCaptured"];
string strfn = Convert.ToString(DateTime.Now.ToFileTime());
FileStream fs = new FileStream(strfn,
FileMode.CreateNew, FileAccess.Write);
fs.Write(barrImg, 0, barrImg.Length);
fs.Flush();
fs.Close();
imNum.Image = (Bitmap)Image.FromFile(strfn);
_listOfNumbers.Add(imNum);
}
dr.Close();
_conn.Close();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
_conn.Close();
}
return _listOfNumbers;
}
And here's my stored proc....
ALTER PROCEDURE dbo.usp_GetKnownImagesAndValues
AS
BEGIN
select ImageCaptured, ImageValue
from CapturedImages
END
Thanks for looking at this. The answer in the end was to put a Thread.Sleep inside the while loop and it started working perfectly. There may be something else I could do, I am obviously waiting for something to complete which is why allowing more time has helped here. If I knew what needed to complete and how to detect when it had completed then I could check for that instead of simply waiting for a short time.
