utf 8 - How to make mysql difference between between uppercase and lowercase -

-

i need in mysql difference between between uppercase , lowercase in query.

because need in java program select user name.

i tried this:

  • database name utf8
  • table name user_table

query:

create table user_table (id int, name varchar(30));  insert user_table (1, "zdi0"), (2, "zdi0");  alter database utf8 character set utf8 collate utf8_unicode_ci;  alter table user_table convert character set utf8 collate utf8_unicode_ci;  select *   name = "zdi0" ;

result:

1  zdi0 2  zdi0

i need alter table not query

thanks in advance

the collation scheme utf8_unicode_ci case insensitive. if want use utf8 collation , support case sensitivity, you'll need use utf8_bin, utf8_bin binary collation scheme. should read on before decide use it. unfortunately far know utf8_bin case sensitive utf8 collation available in mysql.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
