DataSource Controls :: System.Data.SqlClient.SqlException: A Severe Error Occurred On Current Command
Feb 3, 2010
I am facing the following problem when i try to add record in database. "System.Data.SqlClient.SqlException: A severe error occurred on the current command.The results, if any, should be discarded." This exception occurs occasionally, and the sql server log shows the following error whenever the above exception occurs:
Server,Unknown,A user request from the session with SPID 54 generated a fatal exception. SQL Server is terminating this session. Contact Product Support Services with the dump produced in the log directory.
When i fill my sql adapter daAuthors.Fill(dsPubs, "MYTable") sometime i get A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dllmy code can run for a lot hours without any problems but sometime i get the message
When the Stored procedure is executed through SQL Server Management Studio, its taking 23 seconds,When the same Stored proc is called through web app, its throwing below copied exception. It is noticed that when the data is more than 100k records this exception is thrown other wise expected records are shown in UI. Another stored proc from the same app returns over 150k records without any excetpion. Can't conclude that the exception is in Stored proc, because it works from SQL Server Management studio, but throws below exception from Web app.
I have a website having an aunthentication system. When I am setting my website on IIS 6 the code is absolutly working fine. But when i configure the website on IIS 7 (Windows 2008 server) it is showing me the above error. I am using a stored procedure for it
I'm having a spot of bother deploying my database to my host using the Publishing Wizard. I'm using the .sql file generated along with RunSQL.aspx as discussed in this blog by Scott Guthrie.
The issue I am having is that the permission is set to dbo but this seems to be causing an issue with the hosted database as in I get the following error when I run RunSQL.aspx.
An error occured: System.Data.SqlClient.SqlException: Cannot find the user 'dbo', because it does not exist or you do not have permission. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds(String methodName, Boolean async) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at ASP.runsql_aspx.__Render__control1(HtmlTextWriter __w, Control parameterContainer) in d:~hosting details removed for security~RunSQL.aspx:line 88
Is there any way to make the Publishing Wizard set the owner to a particular username, i.e the username I use to access the hosted database.
I am having a problem with my ASP.Net Web application. The application is developed using vb.net and is linked to a SQL Server database. Let me explain how the application works and the problem I am experiencing. The system is an online web app which allows registered users to create a CV online. One of the pages within the app gives users the chance to add a cover note to their CV. The page that allows them to do this consists of only a textarea control and a button control. The textarea allows users to input up to 4,000 characters.
Once the user clicks the 'Save' button to save their cover note info, the following code then executes.This code checks to see if the CV already has cover note info, if it does, then the application runs an update statement, otherwise, it runs an insert statement.The table within the database which records the cover note information is called tbl_covernote and has three columns, covernote_id (int and autoincrement), cv_id(int), covernote_text (nvarchar(max)).
The error which occurs sometimes is as follows:
Dim dr As SqlDataReader Dim param(0) As SqlParameter Finally [code]...
Dim mySqlSelect As String = "Select distinct GroupName from Vecellio.dbo.GroupsTable where GroupName like %" & prefixText & "% order by GroupName desc" Value of string: Select distinct GroupName from Vecellio.dbo.GroupsTable where GroupName like %A% order by GroupName desc
Error: System.Data.SqlClient.SqlException = {"Incorrect syntax near 'A'."}
in my web project i got an error that i couldnt find any solution. the error says: System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. when i work in local there were no problem i put files to our server and i changed the database also. when i work in server in web application in Default.aspx i can connect db and get values without any problem using my DataLibrary
BUT the problem in my web service i also use my DataLibrary in webservice but when i try to run a method in web service it gives me the error which is : System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I'm just a newbie developer using C# (ASP.Net) I'm having trouble in finding the solution in my error:
'System.Data.SqlClient.SqlParameterCollection' does not contain a definition for 'AddWithValue' accepting first argument of type 'System.Data.SqlClient.SqlParameterCollection' could be found (are you missing a directive or an assembly reference?)
I am using parameters before, but never experienced this kind of error.
I've researched the System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. error.
So far all the suggestions indicate either a custom assembly that needs a permission change (I don't have any custom assemblies) or requires a setting change on the server (I'm not the admin). This is for a ReportViewer app using RDLC files. So my questions are: Are there any other things to try troubleshooting?
I'm a complete newb at attempting to understand (I don't) what I've read on this subject regarding the server admin part. What do I need to tell the server admin to check out and/or change? I've looked at the commonly referenced post on wss_mediumtrust.config (I have no idea what that is). Post link. But with no clue on what the post is talking about I don't know what to ask the admin for.

I recently bought domain and hosting from godaddy.com and uploaded my website files based on asp.net on server.
The problem is when i run Default.aspx file in visual studio it runs properly but same set set of files when ran after uploading on server gives error in web.config file.
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
