Could anybody know why this is happening? I'm currently running 2 process at the same time, each process will "insert" different data in a same table. how to avoid this, please advise. thanks.

I currently use JDBC:ODBC driver to connect to MS SQL Server.

You are using the same connection to the database ? If yes, Sugest to use different.
You are using the same statement? If yes, Sugest to use different.


... or post more data about what you are doing (some code will be nice)

Or...if you are running two threads, make the function which writes to the database global to both, and synchronized

PS:  You have asked this question twice...please delete the other one...

Hello waho,

   You have to do one thing with the connection object.

that is
You have to make the complete process into transactions.  If any problem occurs you have to roll back it.

Here is the sample code for you.

Say
Connection c = // get the connection;
c.setAutoCommit(false);
try
{
  Statement s = c.createStatement(SQLQuery);

  do the operations

  s.close();
  c.commit();
  c.close();
}
catch (SQLException e )
{
  if (c != null)
  {
    c.rollback();
    c.close();
  }
}


It will do the needful for you

Cheers,
Muru

both JDBC:ODBC driver and MS SQlserver suck.

get a real database and driver, and do as muru and timyates suggest - force synchronization through a singleton access class taht has the only connection open to the db
