A script to change all tables and fields to the utf-8-bin collation in MYSQL

Question

Is there a SQL or PHP script that I can run that will change the default collation in all tables and fields in a database?

I can write one

Answer 1

I think the fastest way is with phpmyadmin and some jQuery on console.

Go to table's structure and open chrome/firefox developer console (normally F12 on keyboard):

1. run this code to select all fields with incorrect charset and start modify:

   var elems = $('dfn'); var lastID = elems.length - 1;
   elems.each(function(i) {
       if ($(this).html() != 'utf8_general_ci') { 
          $('input:checkbox', $('td', $(this).parent().parent()).first()).attr('checked','checked');
       }       
   
       if (i == lastID) {
           $("button[name='submit_mult'][value='change']").click();
       }
   });
   

2. when page is loaded use this code on console to select correct encoding:

   $("select[name*='field_collation']" ).val('utf8_general_ci');
   

3. save

4. change the table's charset on "Collation" field on "Operation" tab

Tested on phpmyadmin 4.0 and 4.4, but I think work on all 4.x versions
