Is it possible to transmit custom data from SQL 2005 to the client via Exception.Data[key]=value?
The idea
I have a number of SPs that accept userId parameter which must be verified. I have written a simple CLR SP (check_userid_valid) which performs the verification of the userId parameter's value. If the parameter's value is considered invalid an exception is thrown. When the exception (System.Exception) is instantiated additional data is added via the Data property of the exception:
System.Exception ex = new System.Exception();
ex.Data["Source"] = "check_userid_valid"
So, any SP that calls the check_userid_valid with invalid userId is expected to "crash" and the exception with all the additional data is expected to be propagated back to the client which, in turn, could read the data.
Unfortunately, it seems that the ex.Data contains only entries put by the MS SQL 2005 server itself, eliminating the rest.
The question is: how can I supply additional exception data with the exception I do throw from my CLR code on the server-side, so that is can be consumed at the client-side.
Greetings everyone, I am attempting to build my first application using Microsofts Sql databases. It is a Windows Mobile application so I am using Sql Server Compact 3.5 with Visual Studio 2008 Beta 2. When I try and insert a new row into one of my tables, the app throws the error message shown in the title of this topic. '((System.Exception)($exception)).Message' threw an exception of type 'System.NotSupportedException'
My table has 4 columns (i have since changed my FavoriteAccount datatype from bit to Integer) http://i85.photobucket.com/albums/k71/Scionwest/table.jpg
Account type will either be "Checking" or "Savings" when a new row is added, the user will select what they want from a combo box.
Next is a snap shot of my startup form. http://i85.photobucket.com/albums/k71/Scionwest/form.jpg
Where it says "Favorite Account: None" in the top panel, I am using a link label. When a user clicks "None" it will go to a account creation wizard, and set the first account as it's primary/favorite. As more accounts are added the user can select which will be his/her primary/favorite. For now I am just creating a sample account when the label is clicked in an attempt to get something working. Below is the code used.
account.FavoriteAccount = 1;//datatype is an integer, I have changed it since I took the screenshot.
financesDataSet.BankAccount.Rows.Add(account); //The next three lines where added while I was trying to get this to work. //I don't know if I really need them or not, I receive the error regardless if these are here or not.
catch (global:ystem.InvalidCastException e) { //Stops at the following line, this error was caused by 'if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)'
throw new global:ystem.Data.StrongTypingException("The value for column 'FavoriteAccount' in table 'BankAccount' is DBNull.", e);
I have no idea what I am doing wrong, all of the code I used I retreived from Microsofts help documentation included with VS2008. I have tried used my TableAdapter.Insert() method and it still failed when it got to
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
in my refreshDatabase() method it still failed.
When I look, the data has been added into the database, it's just when I try to retreive it now, it bails on me. Am I retreiving the information wrong?
When running the package in VisualStudio it runs properly, but if I let this package run as part of an SQL-Server Agent job, I got the message "The script threw an exception: Exception of type 'System.OutOfMemoryException' was thrown." on my log and the package ends up with an error.
Both times it is exactly the same package on the same server, so I don't know how the debug or even if there is anything I need to debug?

I have a csv file containing some logs from a different system. CSV file contains columns Code & ErrorMessage.
I also have a SQL table called filters. This table also contains code column.
I need to do the following two things
1. Get all record from csv file where code does not exists in Filters (SQL table)
2. Gell all record from csv file where code does exists in Filters(SQL Table) and ErrorMessage contains a specific keyword.
I can add a derived column with the following function
IsExists = FINDSTRING(ErrorMessage,"MyKeyword",1) which will tells me if MyKeyword contains in the message but I donot know how to filter IsExists > 0 and how to do exception join?

We have load-balanced sql server mcs and users will be accessing all the time. We are maintaining user profiles in one mc. Here is the problem. We have a sp which reads profile from one particular mc always. If the mc is down, the sp does not fail gracefully. Instead it causes exception. Is there a way to access sql servers alternatively ie if one server is not responding read data from another sql?

I'm unsure how to handle an SQL Exception correctly when the database is unavailable/offline. I have my aspx file with the C# code-behind, but all of the SQL stuff is done in a separate code file in the App_Code directory.E.g. CODE-BEHINDDatabaseModifier.deleteUser(username); DATABASEMODIFIER.cspublic static void deleteUser(string username){ SqlConnection conn = SqlLogin.SqlConnect; SqlCommand command = new SqlCommand("DELETE FROM <table> WHERE Username = '" + username + "'", conn); conn.Open() command.ExecuteNonQuery(); conn.Close()} Now, that code works perfectly, however if the database I'm connecting to is offline, an SQLException is thrown and because the SQL is handled in my DatabaseModifier class, I'm not sure how to handle it correctly.If I use a Try/Catch block in my code-behind, it doesn't get thrown because the error occurs in my DatabaseModifier class. If I use a Try/Catch block in my DatabaseModifier class, what can I put in the catch block that will inform the user of the database being offline and/or how can I perform a url redirection? Any help is greatly appreciated.

Hi over there,I hope this question is not too simple, but I didn't manage to figure out why...I would need an explanation for following issue:I'm reading data from a database (MSSQL) and it the column "PersonBirthday" is DBNull.I wanted to prevent the error (Textbox.Text = DBNull) with an IIF. The thing is I get thistypecast exception:"Conversion from type 'DBNull' to type 'Date' is not valid." This code is NOT working, why? txtPersonBirthday.Text = IIf(IsDBNull(.Item("PersonBirthday")) = True, String.Empty, CDate(.Item("PersonBirthday")).ToString("yyyy-MM-dd")) When I'm using this code, which is for me obviously the same, just with an if-block it works,and I want to know why - please explain. If IsDBNull(.Item("PersonBirthday")) Then txtPersonBirthday.Text = String.Empty Else txtPersonBirthday.Text = CDate(.Item("PersonBirthday")).ToString("yyyy-MM-dd") End IfThanks in advance,cheers,uquandux If IsDBNull(.Item("PersonBirthday")) Then txtPersonBirthday.Text = String.Empty Else txtPersonBirthday.Text = CDate(.Item("PersonBirthday")).ToString("yyyy-MM-dd") End If

I have a table for which I am iterating through using a foreach loop. On each iteration, I am updating the row with information from an SQL database. During certain cycles of the loop and SQL exception is thrown which I catch and deal with appropriately. However on the next cycle of the loop the SQL exception is still active and always goes into the section which deals with the SQL exception. I have run some tests and the SQL exception should not occur on subsequent loops, but it does.
What I am trying to say is....whenever there is an SQL exception is there anyway to clear it, or set it to null or destroy the SQL exception class. (Destructor perhaps?).
Hi, Im Nithyananda working on a project with SQL server 6.0 Im having a stored procedure which inserts into a table . If I violate the primary key constraint on the table , I get a 2627 error. I would like to replace this error with my own.Could u tell me how to do it? Im an ORACLE guy and relatively new to SQL server. Is it possible for me to propogate the same error message to any front end? In my case ,Im using VC++ as front end. Could someone also tell me the way of calling a SQL stored procedure from VC++?
