Hi guys,
Does any one know how to detect when a SQL transaction has been rolled back in either a windows application or ASP.NET. My Transactions always run but when they are rolled back Visual Basic does not pick up any errors in the 'Try Catch SqlException'. Does any one know a way round this. Sorry for the lack of code. Im writing this post on a friends PC but i wil put up my code as soon as possible. Thanks in advance

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,
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++?
Regards

Hi All
I m new to the sqlserver.In Oracle we can handle exceptions like this
declare
name varchar(20);
begin
select ename into name from emp where eno=&eno;
dbms_output.put_line(name);
exception
when no_data_found then
dbms_output.put_line('No Entry');
end;
/
We will get the message No Entry When corrsponding employee number dosent exists.
In Sqlserver how to handle these things.
Specifically my requirement is with select statement(Like above program)
Waiting for valuable suggestions

Hello,
I am trying to catch an error, but not able to. I am storing the value of @@Error soon after the statement which I believe would generate error. In order to produce the error I have deliberately used a wrong table name. So, the statement breaks but never comes to my error handling code snippet. Instead, it just throws the SQL server error message and quits. What am I doing wrong here? Here is the code snippet. The actual name of the temporary table is #TEMPO_TABLE, but in order to generate the error I have used #TEMPO_. Since this would surely error out, it should go to the label ROLLITBACK. But is not going to that label. Neither is it printing the error number as per the PRINT statement there. It just throws the SQL error and quits the execution. (Or should it NOT??). The Error that it throws it this:
Server: Msg 208, Level 16, State 1, Procedure FEED_PULL_XX, Line 157
Invalid object name '#TEMPO_'.
Can you please let me know whats going wrong here? Thanks a lot in advance.
INSERT INTO Table1
(
[ITAM_ASSET_EUP_BUS_LINE],
[ITAM_MACHINE_STATUS],
[ITAM_OWNER_ID],

I need help please....
I am using exception handling and Transaction handling combined.
The code is written to delete a record from 2 different table.
The purpose of using exception and transaction handling combined is to
make sure that the record is deleted in BOTH table. If there is error
while deleting a record from one of the tables, it will rollback the
database to the original and will stop deleting any record.
However, The Transaction handling is not working. When error occurs
while deleting a record on table A, the code still delete a record from
one table B. The transaction.RollBack() doesn't work. This is my code:
Try
Conn
= New
SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)
Conn.Open()
Trans = sConn.BeginTransaction
For Each row In GridView1.Rows
Dim sql As String = "SELECT * FROM Member
Using Cmd As New SqlCommand(sql, Conn, Trans)
SqlDataSource1.DeleteParameters("MemberID").DefaultValue =
DropDownListMember.SelectedValue
SqlDataSource1.Delete()
SqlDataSource2.DeleteParameters("CarID").DefaultValue =
DropDownListCar.SelectedValue
SqlDataSource2.Delete()
End Using
End If
Next
sTrans.Commit()
Label1.Text = "deleted."
Catch ex As Exception
If sTrans IsNot Nothing Then
sTrans.Rollback()
End If
Label1.Text = "error"
Return
Finally
If sConn IsNot Nothing Then
sConn.Close()
End If
End Try
soo much thanks in advanced!!!
Hi,
I'm trying to do exception handling in a stored procedure, such as IF (@@ERROR <> 0) execute and insert on to an error log table. I have set the volatile @@ERROR global to a variable, but the proc is still throwing a primary key exception; hence, it's not being trapped. My question is why isn't my exception being handled?
Here's my code, your help is much obliged. (my error proc is below the caller)
CREATE PROCEDURE [dbo].[INSERT_STATS_NO_GROUP_PROC]

can I handle exception in SQL functions? how??
I am tring to migrate the Database from Oracle 9i to SQL server 2005 with SSMA which converts function in one procedure and wrapper function because of exception handling in Oracle.
in my package i'm using a for each loop container in order to process all files in a certain folder. everything works fine but of course when i start the service and there are no files available the package waits. is there a way to simply say skip the for each loop or semething like that?
View 2 Replies View RelatedI am trying to handle exceptions using try catch with remote database.

I'm creating a class that will wrap a SqlException and will offer the developer a way of determining how to proceed in handling the exception by offering a suggestion of retrying, revalidating the data, and/or calling the entire process a no go.
One of the ways i've come up with to accomplish this is by using the severity (SqlException.Class) to assist in making a suggestion to the developer.
I'm hoping to get some feedback from the developers who use this forum if they feel severity is or is not the way to go, and also to offer any other ways of accomplishing that they can come up with.
Thanx

I have a cursor that loops through some records.
Upon an exception being caught (i.e. when inserting a record, it violates integrity constraint), I would like to do my normal exception handling routine and then continue with the loop to the next record.
Is this possible? If so, how do I implement this behavior?
Thanks.
I created an SSIS packages on VS 2013 using SQL 2014. I have to use transactions and without MSDTC as we don't have that environment.
Ok my issue when I load a stage table during the process and then I select from that same stage table my records on another table are not being inserted. why? I have done sql profiler an all sql statements are being ran under same SPID.
Package design
1. For each container - this is to process files on a folder
2. Execute sql task - begin tran
3. sequence container - to hold all and organize containers
4. execute sql task - truncate ImpTableA
5. Data Flow task - Import data into ImpTableA from file
6. execute sql task - insert into DimProducts and new products found in ImpTableA that are not in DimProducts so I'm joining the 2 tables together as a outter join and getting the new ones.
7. Execute sql task - commit tran
8. Execute sql task - rollback tran
On Step 6 I don't find any new rows on DimProducts even though I know there is new products. I have tested the sql statement in SSMS and it works and I find new rows. For some reason SSIS is not finding new products, I'm assuming that the rows are not committed yet and therefore can query them but I thought if I was under the same transaction and SPID I would be able to read uncommitted rows.
Need to be able to read from table that was just inserted in a transaction incase of a failure roll everything back.
I'm trying to get to grips with the formview control and have a problem regarding where an exception is raised if SQL server raises an error when an insert is taking place. I am new to both asp.net & c#
I have put the following code in the SqlDataSource2_Inserted & Formview1_Inserted events as a way of determining where the exception is raised:
if (e.ExceptionHandled){ string exceptionmessage = e.Exception.Message; lblStatus.Text = exceptionmessage;}
These two events are the only one's that have the ExceptionHandled and Exception properties.
I run the code with data that will raise a duplicate key error from SQL Server but the error is not being caught by either of these two handlers. All I get is a page that starts with
Server Error in '/SourceCode' Application.
Violation of UNIQUE KEY constraint 'IX_reftblAntigens'. Cannot insert duplicate key in object 'reftblAntigens'.The statement has been terminated.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Violation of UNIQUE KEY constraint 'IX_reftblAntigens'. Cannot insert duplicate key in object 'reftblAntigens'.The statement has been terminated....
Is there somewhere else I should be looking to handle this sort of thing? I thought using the databound controls would make life easier but I'm actually finding it more of a pain than coding everything myself.
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.
private void lnkFavoriteAccount_Click(object sender, EventArgs e)
{
FinancesDataSet.BankAccountRow account = this.financesDataSet.BankAccount.NewBankAccountRow();
account.Name = "MyBank Checking Account";
account.AccountType = "Checking";
account.Balance = Convert.ToDecimal("15.03");
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.
this.bankAccountTableAdapter1.Update(financesDataSet);
this.financesDataSet.AcceptChanges();
refreshDatabase();
}
the refreshDatabase() code is here:
private void refreshDatabase()
{
this.bankAccountTableAdapter1.Fill(this.financesDataSet.BankAccount);
//Aquire a count of accounts the user has
int numAccounts = financesDataSet.BankAccount.Count;
//Loop through each account and see which one is the primary.
for (int num = 0; num != numAccounts; num++)
{
//Works ok in frmMain_Load, but when my lnkFavoriteAccount_click calls this, it throws the error.
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
{
//Display the primary account on our home page. User can click the link label & be taken to their account register.
this.lnkFavoriteAccount.Text = this.financesDataSet.BankAccount[num].Name.ToString();
this.lnkFavoriteFunds.Text = this.financesDataSet.BankAccount[num].Balance.ToString();
break;
}
}
}
and my form_load code
private void frmMain_Load(object sender, EventArgs e)
{
refreshDatabase();
}
So, when I click on the lnkFavoriteAccount label, and my new row gets added, the app stops at the following line in my DataSet.Designer
[global:ystem.Diagnostics.DebuggerNonUserCodeAttribute()]
public byte FavoriteAccount {
get {
try {
return ((byte)(this[this.tableBankAccount.FavoriteAccountColumn]));
}
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);
}
}
set {
this[this.tableBankAccount.FavoriteAccountColumn] = value;
}
}
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?
Thanks for any help you guys can offer.

Hi,
I got an strange problem with one of my packages.
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?

Hi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated

View 10 Replies View RelatedWe 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?

View 3 Replies View RelatedHi All, Please help me out how to implement the locking in below scenarioReq - There are two tables Table1 & Table2 If I will insert in table1 then related data fields will be auto updated in table2 , similarly based on the data in table2 table1 data needs to be updated. Now the sync of table1 & table2 is working fine.My prob is we are handling the updation/insertion from the UI screens . Two separate screen for each table. When we have multiple user accessing the screens say - User1 updates table1 and User2 updates table2 then we need to implement the locking so that at one time one screen will allow updation in the table1 and hence table2.The other screen shouldnt allow updation in table2 and hence in table1.This is very common locking functionality ...but am not getting any way to implement it , Please advise.Srain.
