SQL Exception

Jul 23, 2007

I am trying to insert data into a table and I am getting a SQL Exception: System.Data.SqlClient.SqlException {"Incorrect syntax near 'nvarchar'. Must declare the scalar variable "@"."} 

This is my subroutine that is executed once the submit button is clicked.

Please advise. Thank you for your time!

'((System.Exception)($exception)).Message' Threw An Exception Of Type 'System.NotSupportedException'

Jan 16, 2008

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.

The Script Threw An Exception: Exception Of Type 'System.OutOfMemoryException' Was Thrown.

Jan 31, 2007

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?

Regards,

Jan

Sp Exception

Aug 17, 2000

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?

Handling SQL Exception

Nov 14, 2007

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.

SQL Exception Error

Mar 4, 2005

Hello,

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?).

Regards

Dezzy

Exception Handling

Aug 22, 2007

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.

Exception Reporting !?!

Jan 8, 2008

Hi everyone,

I'm trying to figure out, how I can solve following problem. I need to generate an overview of a department (parameter) of their employees which have visited a course (2nd parameter) and which haven't. For this I'm working with following tables:

- Employee Data (incl. Unit Code)
- Participant Table (one employee can have none, one or more entries - for every participation she/he gets one entry)
- Course Table (with details of the course - out of here I need to choose the course)

The participant table is merged to the course table over a course # (primary key in course table). The employee data is merged to the participant table over an employee #.

Which data I can generate until now:

- Participants of the course of the chosen department
- Employees which have never visited a course of the chosen department
and
- Employees which haven't visited the specific course but have visited an other one

---> my problem now, is to get those employees which haven't participated at the specific course but participated in an other one together with the ones which have participated. When I set a filter for the course number "NOT = 224847362" then I receive all those, which have participated in an other course - that's ok - but as mentioned before, an employee can participate in more than just one course. Thus when I make an UNION I get double entries - one for the participation and one for the "participation in an other course".

Can someone help? That would be fantastic!

Cheers,
Swisscougar

Exception Handling

Sep 24, 2007



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],
[ITAM_ASSET_ADMIN],
[ITAM_MODEL],
[ITAM_ASSET_NAME],
[ITAMMACHINE_PURPOSE]
)
SELECT
[ITAM_ASSET_EUP_BUS_LINE],
[ITAM_MACHINE_STATUS],
[ITAM_OWNER_ID],
[ITAM_ASSET_ADMIN],
[ITAM_MODEL],
[ITAM_ASSET_NAME],
[ITAMMACHINE_PURPOSE]
FROM
#TEMPO_

SET @ErrNo = @@Error
PRINT '@ErrNo is ' + ltrim(str(@ErrNo)) + '.'
IF @ErrNo <> 0
Begin
PRINT '@ErrNo is ' + ltrim(str(@ErrNo)) + '.'
GOTO ROLLITBACK

I followed the instructions from one of the article about Microsoft SQL Server 2005 JDBC Driver 1.0 (Note I'm using Microsoft SQL Server 2000 and this driver is compatible with SQL Server 2000): copy sqljdbc_xa.dll to SQL Binn directory and execute the script xa_install.sql. And XA Transaction is enabled on the SQL Server 2000 running machine.

Even after have finished all the steps I still get the same error.

Pls help me on this problem.

Thanks in advance

Exception Occurs If Using Clr Sql

Mar 28, 2008

Hi all:
We are using a simple clr function in sql server, which splits input strings by a given delimiter. The code is in €œclr_sql.cs€?. And I wrote a simple stored proc in SQL Server 2005 which calls this function(storedproc.slq). Then I used a test application, which creates 80 threads to call this stored proc continuously. The client code is in client.cs. The TPS can reach to 2000+ in my test. Unfortunately, exception occurs sometimes (about 0.01%). Most of the exceptions are:
System.Data.SqlClient.SqlException: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
And there are a few others:
System.Data.SqlClient.SqlException: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.
System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding
I wrote a dummy T-Sql stored proc, which returns all the rows from an existing table (60 rows, the same dataset as the test above) directly. It€™s much faster than the clr one, and no exception occurs. And I also wrote a T-Sql stored proc which doing the same task as the clr one and is slower. It doesn€™t fail, neither.
To summarize my problem: exception occurs when using clr sql, but it vanish when using T-SQL. But we need CLR SQL because of the performance is better.
I€™m looking forward to hear from you. Thanks in advanceJ
