what is ConnectionID

Hi,
$userName = 'root';
$password = '199abc';
$host = 'localhost';
$port = '3306';
$connectionID = ''; <-- what is this

Can you please tell me what is connectionID. I have tried giving my Database Name.

I am seeing this error message - Warning: mysqli::mysqli(): (HY000/1045): ...blah..blah at line 60

Please suggest.

This is how you use the class to build your ORM.

//
// Create the conntection property for the connection wrapper I use
//
$dbConnectProperty = new dbConnectProperty() ;
$dbConnectProperty->host = 'localhost' ;
$dbConnectProperty->password = 'password' ;
$dbConnectProperty->userName = 'username' ;

//
// Create the object and tell it what database you will use in the
// database connection to mysql.
// It uses the Mysqli extension to connect.
//
$DataObjectBuild = new DataObjectBuild('databasename' , $dbConnectProperty) ;
$DataObjectBuild->GetTableList() ;
$DataObjectBuild->GenerateDataClasses() ;
