Hi,
Anyone has a link that can help me to convert php code that connects to mysql database to java?
I managed to ceonnect to the database but I have problems with commands such:
if (mysql_num_rows($result7)!=0 && $result7!=0) that i dont know how to convert into java commands.
Thanks

Answer 1

you should consult the API and formost the ResultSet API.
but there is no way to get row count from a result set.
this is because the assumed behaviour in JDBC is more like the method mysql_unbuffered_query()
http://www.php.net/manual/en/function.mysql-unbuffered-query.php
if you use that method than you can't get the row numbers from the result set in PHP either.
however i can tell you this...
doing this in php...
$rs = mysql_query("SELECT a,b,c FROM AlphabetTable;");
if($row = mysql_fetch_row($rs)){
  //process first row
  echo $row[0]." ".$row[1]." ".$row[2]."\n";
  while($row = mysql_fetch_row($rs)){
     // process rows 2 through n
    echo $row[0]." ".$row[1]." ".$row[2]."\n";
}else{
  echo "No Rows Found!\n";
}in Java would be like...
Statement s = connection.createStatement();
ResultSet rs =  s.executeQuery("SELECT a,b,c FROM AlphabetTable;");
if(rs.next()){
  // process first row
  System.out.println(rs.getString(1)+" "+rs.getString(2)+" "+rs.getString(3));
  while(rs.next()){
     // process rows 2 through n
    System.out.println(rs.getString(1)+" "+rs.getString(2)+" "+rs.getString(3));
}else{
  System.out.println("No Rows Found!");
}
