I am working with a Console app that is using Parallel.foreach for threading purposes.
It was developed using .net 4.5 vs 2012 that is retrieving and inserting data into sql server (2008 r2) that is on site. So there should be no network issues because the sql server is local. My application is currently the only one using the database I am getting a ton of timeouts from several threads at the same time. What makes this more confusing is I can call this application over and over but that one time I get the timeout. Maybe this is simple as increasing the timeout but I wonder if there is something else going on
This is the stored procedure I am calling
Select table.Id from Table WITH (NOLOCK)
inner join table2 c WITH (NOLOCK) on c.Id = table.TableId
inner join Table3_xref x WITH (NOLOCK) on x.TableID = c.id
inner join Table4 p WITH (NOLOCK) on p.id = x.id
where
value = #Parm1
and p.Value1 = #Parm2
and c.Value2 = #Parm3
and Table.Void = 0
This is the exception
System.Data.SqlClient.SqlException (0x80131904): Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out

This is what my code looks like
try
{
using (DbConnection con = Database.CreateConnection())
{
IDbCommand cmd = new SqlCommand(sSQL, (SqlConnection)con);
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
IDataReader reader = cmd.ExecuteReader();
if (reader.Read())
{
result = true;
}
}
}
After a while the program is able to recover and continue its task. I would consider this a duplicate to this but I am not using database mirroring and this is not happening on connection.open
I can increase the time out from the default but I am not real sure this should be a issue.

I am trying get the data from database but I am getting this error. I am sure I am missing some simple logic but I couldn't figure out what's wrong with the query as it is working fine directly on DB.
SqlCommand retrievedgeids = new SqlCommand("Select edgeid from Edges where fromIntersection = #fromid and toIntersection = #toid", sqlconnection);
retrievedgeids.Parameters.AddWithValue("#fromid", fromid);
retrievedgeids.Parameters.AddWithValue("#toid", toid);
using (SqlDataReader reader = retrievedgeids.ExecuteReader())
{
while (reader.Read())
{
if (reader["edgeid"] != System.DBNull.Value)
{
edgeids.Add(Convert.ToInt32(reader["edgeid"]));
}
}
}
And this is the error message:
System.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near '='.

Can you help me figure out this issue?
Here is the link to the Microsoft documentation for the Parameter class you are using :
https://learn.microsoft.com/en-us/dotnet/api/system.data.sqlclient.sqlparameter?view=dotnet-plat-ext-5.0
You would need to change your code to something like this :
System.Data.SqlClient.SqlCommand retrievedgeids = new System.Data.SqlClient.SqlCommand("Select edgeid from Edges where fromIntersection = #fromid and toIntersection = #toid", sqlconnection);
System.Data.SqlClient.SqlParameter fromIdParameter = new System.Data.SqlClient.SqlParameter("fromid", SqlDbType.Int);
fromIdParameter.Value = fromId;
retrievedgeids.Parameters.Add(fromIdParameter);
Use Parameters.Add instead of AddWithValue like this:
retrievedgeids.Parameters.Add("#fromid", SqlDbType.Int);
retrievedgeids.Parameters["#fromid"].Value = fromid;
I am sorry before because the title too general. I just wonder how it's happen in this code:
foreach (var item in list)
{
.........
using (SqlCommand cmd = new SqlCommand(#"SELECT some_fields FROM tbl WHERE id=#id", new SqlConnection(db.ConnectionString)))
{
cmd.Connection.Open();
cmd.Parameters.AddWithValue("#id", item.id);
var reader = cmd.ExecuteReader();
while (reader.Read())
{
//do something
}
cmd.Connection.Close();
}
.........
}
Execution timeout happened on the second loop. First loop was no problem. Is there something wrong in this syntax? Please tell me.

Thanks in advance
Try increasing the Connection Timeout
// Setting command timeout to 3 Minutes (60*3=180 Seconds)
cmd.CommandTimeout = 60*3;
Do this before ExecuteReader()
How long it takes for your cmd.ExecuteReader(); to execute?
in your connectionstring, you may want to get a try by allowing multiple active resultset.
see if this resolve your issue? like:
<add name="yourDBConn" connectionString="Data Source=yourInstance;Initial Catalog=yourDB;Persist Security Info=True;User ID=user;Password=pwd;Connection Timeout=30;MultipleActiveResultSets=True;" providerName="System.Data.SqlClient" />
A value of 0 indicates no limit (an attempt to execute a command will wait indefinitely).
The default is 30 seconds. if Read requires two network packets, then it has 30 seconds to read both network packets. If you call Read again, it will have another 30 seconds to read any data that it requires.(Here is the problem exist before expiring timeout it is again calling reader )
Solution 1 is increasing the connection timeout or setting the value to Zero. Another Solution might work is use using(var reader = cmd.ExecuteReader();
I am trying to create a web in ASP.net where it shows me publications that our organization puts out. Here's some code from the cs file.
//2nd - Setup SQL Command
SqlCommand cmd = new SqlCommand("SELECT [IDTip], [Date], CONVERT(nvarchar(100),[Date], 1) AS Released, [Title], [Image], REPLACE(CONVERT (nvarchar(MAX),[Tip]), '</p>\r\n\r\n<p>', '<p></p>') AS ContentConverted, Recognition, FROM tips WHERE IDTip =" + Request.QueryString["IDTip"], new SqlConnection(HealthReachConString));
//3rd - Attempt to open the connection to the DB
cmd.Connection.Open();
//4th - Go and fetch some data and apply it to our controls
SqlDataReader objReader = cmd.ExecuteReader();
while (objReader.Read())
{
lblDate.Text = objReader.GetString(2);
lblTitle.Text = objReader.GetString(4);
lblTip.Text = Convert.ToString(objReader["ContentConverted"]);
imgContentPicture.ImageUrl = "~/files/Health_Tips/" + objReader.GetString(5);
if (objReader.GetString(5) == " " || objReader.GetString(5) == "")
{
imgContentPicture.Visible = false;
}
else
{
imgContentPicture.Visible = true;
}
}
objReader.Close();
cmd.Connection.Close();

Any idea what's going on?
To clarify your issue, the extra comma is indicating to SQL that another parameter is present, however your parameter is your FROM. Once you remove the comma before the FROM your syntax should be valid. Assuming that you have indicated proper syntax for your CONVERT and Alias functions.
I'd also like to indicate that your query is prone to SQL Injection. To resolve that portion you should do:
SELECT [IDTip], [Date],
CONVERT(nvarchar(100),[Date], 1) AS Released, [Title], [Image],
REPLACE(CONVERT (nvarchar(MAX),[Tip]), '</p>\r\n\r\n<p>', '<p></p>') AS [ContentConverted], [Recognition]
FROM [Tips]
WHERE ([IDTip] = #Id);
That is what I saw as faults in the query in my review.
Extra junk:
SELECT ... Recognition, FROM ...

I am trying to write linq expression that updates all my records and sets their Default field based on id match condition:
m_context.Languages.Update(x =>
new Language {Default = x.LanguageId == _languageId ? true : false}

What I am going wrong? I tried other conditions and it seems it works fine until another field participates in condition:
context.Languages.Update(x => new Language {Default = !x.Default}); //fine
context.Languages.Update(x => new Language {Default = true == true}); //fine
context.Languages.Update(x => new Language {Version = x.Version + 1}); //fine
context.Languages.Update(x => new Language {Default = x.LanguageId == langId}); //error
I'm trying to save 8,000 characters to a SQL Server Express database table, and this may be smaller or larger in the future, and I'm getting an exception saying that the data will be truncated.
I've already set the column to varchar(max) and don't know if there is another setting for the ORM itself.
Any help is appreciated

#makerofthings7, my best guess about the re-appearance of the error after the fix is that the model and the database are not in synchronous.
It seems that you have modified the table in the storage model in Visual Designer and in order to complete the fix, I would suggest to you to run the Update Database From Model wizard and to transfer the change in the database.
I hope this helps.
