    If you don't know that after my comment, then i don't believe that code you posted is your own

    public static final int BUFSIZE= 1024;
    

    Instead of the above, get the buffer size from the command line. Get also the rate in seconds, with which you initialize a java.util.Timer to send at that rate per second

    Of course, these parameters are being set at the application level and might only be a partial view of what actually happens in the network


    Thanks but can you write some guiding code to explain more?
  4. In Topic: Joining two tables and query them!

    ON exhibitions.picture.name
    


    You need to tell it what column - FROM EACH TABLE - to join off of. In this case what column in artist?

    ON exhibitions.picture.name  = artist.?????
    


    The column name in artist is 'name' and also in picture is 'name'. The first image is for the artist table while the second image is for the picture table.
  5. In Topic: Copy records from a table in one database to another database.

    There's nothing wrong with your syntax, really. You just need to expand your query to include that field. Like:
    INSERT INTO db1.mytable(field1, field2, fieldN)
    SELECT field1, field2, fieldN
    FROM db2.mytable;
    
    

    If any of the fields in the INSERT don't actually have a value in the table you are SELECTing from, you can provide a static value instead, to serve as a default value.
    INSERT INTO db1.mytable(field1, field2, fieldN)
    SELECT field1, 'value for field2', field3
    FROM db2.mytable;
    
    

    There each "field2" field in the INSERT will have the string value in the second field of the SELECT.



    Thanks again! I am still facing the problem of duplicate entry and doesn't allow my query to be OK. What can I do?
