Use Scope_Identity instead. It's the recommended option.

from msdn
IDENT_CURRENT is similar to the SQL Server 2000 identity functions SCOPE_IDENTITY and @@IDENTITY. All three functions return last-generated identity values. However, the scope and session on which last is defined in each of these functions differ:
* IDENT_CURRENT returns the last identity value generated for a specific table in any session and any scope.
* @@IDENTITY returns the last identity value generated for any table in the current session, across all scopes.
* SCOPE_IDENTITY returns the last identity value generated for any table in the current session and the current scope.
So SCOPE_IDENTITY seems the right one in a multi threaded environment.

More reason not to use identities at all.

Hi.
I try to connect sql server 2005 through OBDC connection bt i face a error please give me some solution, i face this error
ERROR [08001] [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.
ERROR [01000] [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).
my Coding is
OdbcConnection conn = new OdbcConnection("Driver={SQL Server};Server=test;UID=sa;PWD=java;");// test is my ODBC connection name
string query = "INSERT INTO test VALUES ('" + textBox1.Text + "','" + textBox2.Text + "')";
OdbcCommand cmd = new OdbcCommand(query, conn);
try
{
conn.Open();
cmd.ExecuteNonQuery();
MessageBox.Show("Record Inserted.");
}
finally
{
conn.Close();
}

Are you sure your user name and password are correct?
The database name appears to be missing as well.
|
|
|
|

thanks for reply.
yes username and password is correct. where i put database name???
|
|
|
|
|
OdbcConnection conn = new OdbcConnection("Driver={SQL Server};Server=test;DataBase=DataBaseName;UID=sa;PWD=java;");

try this:
<br />
OdbcConnection conn = new OdbcConnection("DSN=test;UID=sa;PWD=java;");<br />
this is assuming that you have created a DSN entry with name test.

Try this to include your database nam:
OdbcConnection cn= new OdbcConnection("Driver={SQL Server};Server=mySQLServer;UID=sa;
PWD=myPassword;Database=Northwind;");
Also make sure that your Sql Server 2005 allows remote connections because by default it doesn't!

hi,
i have got 1000 records in access table and i want to read alternate data.
ie 500 records out of 1000.
how to advance the reader to next record?
|
|
|
|
|
You need to implement your own logic in a loop.
Your logic could simply be something like
While reader.Read(){<br />
intCounter++;<br />
if (intCounter % 2 == 0){<br />
Console.WriteLine(reader(0).ToString())<br />
}<br />
}<br />
End While

One of the method is missed in the call stack when code is compiled in release mode. Here is the sample code:
static void Main(string[] args)
{
MyFunc();
Console.ReadKey(false);
}
public static void MyFunc()
{
Console.WriteLine(Program.GetCallStack());
}
public static string GetCallStack()
{
System.Diagnostics.StackTrace callStack = new
System.Diagnostics.StackTrace();
string s = "";
int index = 0;
while (true)
{
System.Diagnostics.StackFrame frame =
callStack.GetFrame(index);
if (frame == null) break;
System.Reflection.MethodBase method = frame.GetMethod();
if (index 0) s = " --" + s;
s = method.DeclaringType.Name + "." + method.Name + "()" + s;
index++;
}
return (s);
}
Why is it so?

Make sure that you're created PDB's when compiling in Release configuration.
In VS2008, you can set the property using the project properties -> Build -> Advanced... -> Debug Info.
|
|
|
|
|
My setting is Debug Info=pdb only
but it does not work

Hmm, I take it that the PDB's are in the same folder as the dll?
What specifically isn't working?
When I run your code I get the following output (I inserted a Environment.Newline):
Debug:
ThreadHelper.ThreadStart()
ExecutionContext.Run()
HostProc.RunUsersAssembly()
AppDomain._nExecuteAssembly()
Program.Main()
Program.MyFunc()
Program.GetCallStack()
Release (with PDB)
ThreadHelper.ThreadStart()
ExecutionContext.Run()
HostProc.RunUsersAssembly()
AppDomain._nExecuteAssembly()
Program.Main()
Program.MyFunc()
Program.GetCallStack()

Here is my output (RUN IT VIA COMMAND PROMPT AND NOT F5 in Visual Studio)
C:\Applications\poc\ConsoleApplication1\ConsoleApplication1\bin\Release>consolea
pplication1
Program.Main()Program.GetCallStack() --
C:\Applications\poc\ConsoleApplication1\ConsoleApplication1\bin\Release>cd..\deb
ug
C:\Applications\poc\ConsoleApplication1\ConsoleApplication1\bin\Debug>consoleapp
lication1
Program.Main()Program.MyFunc()Program.GetCallStack() --
NOTE : - Program.MyFunc() is missing in release mode.

Anyone has any information on this? Its bit urgent!!

I've run the code from command prompt and you're right. I believe that this is a compiler optimisation as MyFunc is so simple. If you run the following code:
static void Main(string[] args)
{
MyFunc();
Console.ReadKey(false);
}
public static void MyFunc()
{
Console.WriteLine("Begin");
Console.WriteLine(Program.GetCallStack());
Console.WriteLine("End");
}
public static string GetCallStack()
{
System.Diagnostics.StackTrace callStack = new
System.Diagnostics.StackTrace();
string s = "";
int index = 0;
while (true)
{
System.Diagnostics.StackFrame frame =
callStack.GetFrame(index);
if (frame == null) break;
System.Reflection.MethodBase method = frame.GetMethod();
if (index == 0) s = " --" + s;
s = method.DeclaringType.Name + "." + method.Name + "()" + Environment.NewLine + s;
index++;
}
return (s);
}
You should get the following output:
Debug:
Begin
Program.Main()
Program.MyFunc()
Program.GetCallStack()
--
End
Release (with PDB):
Begin
Program.Main()
Program.MyFunc()
Program.GetCallStack()
--
End
