i download JDBC (JDBC service Pack 1) on Solaris, to connect to Microsoft sql 2000 (Developer Edition, Service Pack 2).
i used the code like that:
Connect=DSN=jdbc:microsoft : sqlserver://x.x.x.x:1433;UID=sa;PWD=*******
but the program show this error:
java.sql.DriverManager.getConnection threw an exception
PLZ can any one help me.
When performing a failover the DriverManager.getConnection method never returns from it's call. I used a modified version of the test program included in the sqljdbc help file (below). If the principle server is server2 and a failover is performed, the program works just fine. If the priciple server is server1 and a failover is performed, the hang occurs. The sql servers are not on a domain, are in the same workgroup, have certificates setup between them. Sqljdbc version used is 1.1.1501.101. I rolled back to version 1.1.1320.0 and the DriverManager.getConnection exceptioned. Not sure if this is a setup issue or a common problem. Anyone have any suggestions or seeing similar issues?
Thanks

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,

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.

I have a very simple SSIS package which I execute from VB.NET using the ManagedDTS namespace objects. I am getting a very sporadic error saying "The script threw an exception. Object reference not set to an instance of an object"
All the package does is insert rows from a filename that I pass into the package from code, and then rename the file in a script task. The script task is what is causing this error. If I remove/disable the script task the package executes everytime without error. I have even commented out all the code that might throw an exception and it still fails atleast 3 out of 10 times. Here is my code in the script task:
Public Sub Main()
'
' Add your code here
'
Dim e As String = ""
Dim strFileName As String = ""
Dim strDestination As String = ""
Try
'strFileName = Dts.Variables("User::FileName").Value.ToString()
'strDestination = System.IO.Path.ChangeExtension(strFileName, "processed")
'If File.Exists(strFileName) Then
'System.IO.File.Move(strFileName, strDestination)
Dts.TaskResult = Dts.Results.Success
'End If
Catch ex As Exception
e = ex.Message
Dts.TaskResult = Dts.Results.Failure
End Try
'CreateControlFile(strFileName, strDestination, e)
End Sub
NOTE: I never get a package FAILURE as I would if it got into the CATCH block. I believe this is an error being generated from the Package processing engine.
Here is some output from the VB.NET application debug window:
This output's once for every "exception" thrown by each package execution.
A first chance exception of type 'System.NullReferenceException' occurred in VBAssembly
A first chance exception of type 'System.NullReferenceException' occurred in VBAssembly
A first chance exception of type 'System.IO.IOException' occurred in mscorlib.dll
Here is the code I use to execute the package:
Public Function ConsumePackage(ByVal strPath As String, ByVal strPackage As String) As Boolean
Dim bReturn As Boolean = False
Dim pkg As New Package
Dim app As New Application
Dim result As DTSExecResult = DTSExecResult.Failure
Try
pkg = app.LoadPackage(strPackage, Nothing)
Debug.Print("Executing package on file: " + strPath)
pkg.Variables("FileName").Value = strPath
result = pkg.Execute()
If result = DTSExecResult.Failure Or result = DTSExecResult.Canceled Then
For Each d As DtsError In pkg.Errors
ErrorMessage += d.ErrorCode.ToString() + d.Description.ToString() + vbCrLf
Next
Return False
End If
bReturn = True
Catch ex As Exception
bReturn = False
Finally
pkg.Dispose()
pkg = Nothing
app = Nothing
End Try
End Function
My SqlConnection is causing an error "sqlConn.ServerVersion threw an exception of type System.InvalidOperationException". Everything I have read seems to suggest that there is a problem with my SQLConnection parameters but as you can see from the commeted code below I have tried three different servers with four different configurations. I am out of ideas on what is causing the error.
Thanks - Amy
Here is a section of my code:
String sqlStmt = "Select [UserName], [Password], [Last], [First] from Contacts Where Login=@Uid AND Password=@Pwd";
SqlConnection sqlConn = new SqlConnection("Data Source=localhost;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=pe2800;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=HorizonDC02;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=HorizonDC02;Initial Catalog=test;User ID=username;Password=password;");
SqlCommand sqlCmd = new SqlCommand(sqlStmt, sqlConn);sqlCmd.Parameters.Add("@Uid", SqlDbType.VarChar, 30).Value = uid;sqlCmd.Parameters.Add("@Pwd", SqlDbType.VarChar, 30).Value = pwd;sqlCmd.Connection.Open();
Hi All,
I need to refresh my cube daily and once this processed is done, i will update in ETL table with lastcubeprocessedtime in my timestamp column. Actually i am using IBM db2 provider since my ETL table resides in IBM DB2 source.
In my first task i am using script task where i will check whether my timestamp column value is NULL or not.
I am getting error like "The script threw an exception : keyword not supported: 'network port'." when this script task executes.
Moreover i am getting another error like "The execution succeeded, but the number of error raised(1) reached the maximum allowed(1); resulting in failure. This occurs when the number of errors reaches the number of specified in MaximumErrorCount. Change the MaximumErrorCount or fix this errors." For this error i have changed MaximumErrorCount value from 1 to 100 in dataflow task.
Can anyone tell me what might be the problem for these two errors?
Thanks in advance

I have VS2003 and VS2005 installed as well as SQL Server 2000 and SQL Server 2005 Tools. I have RS2000 and RS2005 installed. RS2000 works fine in VS2003. When using VS2005 and opening a Microsoft sample project for 2005, I get the error listed in the subject line.
When trying to create a new project and connecting to an Oracle database or a SQL Server 2005 database, I get the following error: "A connection cannot be made to the database. Set and check the connection string." The connection works fine when the test button is clicked, but fails when continuing in the wizard.
Any suggestions. We are trying to migrate from RS2000 to RS2005 and nothing in 2005 works.

View 3 Replies View RelatedHi guys,
I need to know on how to connect MS SQL Server Database if I use Java (JCreator).
1. How to connect
2. How to use call stored procedures.
Many thanks.
My preferred programming language is Java (sorry Microsoft). I've searched for examples of running DMX queries into an Analysis Services database from Java but failed to locate any. I've seen suggestions that XMLA could be used but again, I can't locate any examples (in any language). For my current project I ran up the white flag and used C# instead but this wouldn't be an option in other cases. It would be possible to make the DMX calls from C# objects and call those from Java but that's pretty labourious to code.
Suggestions?
Anyone have any tips for using Java against SQL Server? Our ITdirector is thinking of making us a Java shop, but I really would liketo stay with SQL Server as our RDBMS. We have Oracle Financials butour in-house development (currently VB6 client-server, soon to bereplaced by a service-oriented architecture based around Sonic andincluding SalesForce, both of which are Java) has been against SQLServer. He says five years ago at his old company Java/SQL Server hadlousy performance. I vaguely remember that since then Microsoft cameout with their own JDBC driver for SQL Server... Anyone have experiencewith this? Any performance tips will be hugely appreciated.TIA

I am in the process of evalulating using SSRS with our Java app and I have a couple questions up front:
I see you can call SSRS thru web services and display an HTML report. Can you have the report go straight to the printer, rather then preview. So we can offer both Print and Print Preview options.
I see the page streaming option. So on page preview we could ask for page 1 to get a snappy display, then ask for the rest of the report to generate in background?
thanks.

Hi.. We have a java application which connect to our MS-SQL DB during midnight using JDBC connector and extract information. But very often ,the java applicatian halted and because of the deadlock as shown below.
Caused by: java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Transaction (Process ID 54) was deadlocked o n lock resources with another process and has been chosen as the deadlock victim.
now the java programmer is blaming me that the MS SQL DB is having deadlock and cause their Java application to hang.
Is there any way to clear the deadlock before the the Java applcation run or how to prove the Java application script itself is having problem and causing the deadlock ?
