Javascript : Reload Target / Parent Window From Second Child Window

I have problem like this guy on this link.

Solution : use window.name, and target it to reload

On parent page :

window.name = "parent_window";

On the first child page :

function open2print(id_cek_in,diskon) {
 window.open( "cek_print.php?id_cek_in="+id_cek_in+"&cetak=y&diskon="+diskon, "print","status=no,menubar=no,toolbar=no,scrollbars=yes,resizable=yes,width=600,height=800" )
}

On the second child page :

function reloadWin(){
 var parent_window = window.open("", "parent_window");
 parent_window.location.reload(true);
}

<body onload=reloadWin();>

So when the second child window load, it will be reload parent window.

PS : I hate javascript, too many parents and children involved :(

phpMyAdmin : How to Import Large CSV

Case : You have a big file size csv to import to mysql using phpmyadmin
Solution : Use mysql script instead of import form from phpmyadmin (that will save you a lot of time)
Script :

LOAD DATA LOCAL INFILE 'file_name.csv'
INTO TABLE table_name
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
(column1,column2,column3);

Note : place your csv file in your phpmyadmin directory
