Subject RE: Stored proc returning result set (and output params) with MS SQL server
Date Tue, 15 Apr 2008 08:37:51 GMT
Hello Andrus,

The JDBC code used to call the stored procedure is really trivial. 
Please find below our test case.

Connection connection = null;
CallableStatement statement = null;
try
{
  connection = DriverManager.getConnection("jdbc:jtds:sqlserver://localhost:1433;databasename=mydb;",
"guest", "guest");
      
  statement = connection.prepareCall ("{ call spXXX(?, ?, ?, ?, ?, ?, ?, ?, ?, ?) }");
  statement.registerOutParameter(1, java.sql.Types.VARCHAR);
  statement.registerOutParameter(2, java.sql.Types.VARCHAR);
  statement.registerOutParameter(3, java.sql.Types.VARCHAR);
  statement.registerOutParameter(4, java.sql.Types.NUMERIC);
  statement.registerOutParameter(5, java.sql.Types.NUMERIC);
  
  statement.setString(6, "guest");
  statement.setString(7, "myData");
  statement.setInt(8, 60);
  statement.setInt(9, 1);
  statement.setInt(10, 1);

  statement.executeUpdate();
  
  if (statement.getMoreResults())
  {
    ResultSet rs = statement.getResultSet();
    while (rs.next()) 
    {
      System.out.println(rs.getInt("ID")); 
    }
  }
      
  System.out.println("Proc status: " + statement.getString(1) + " " + statement.getString(2)
+ " " + statement.getString(3) + " " + statement.getInt(4) + " " + statement.getInt(5));
}
catch (Exception e)
{
  e.printStackTrace();
}
finally
{
  close(connection, statement);
}

Again, we would like to insist on the fact that the crash occurs when the called stored procedure
does not return any result set. 

Thank you again for your help. We appreciate very much.

Marc Gabriel

Could you post the JDBC code you used to read the data?
