Hello, All!<br><br>Can anyone suggest how to improve the performance of a query like this:<br><br>CREATE TABLE u_mashiah.pagelinks (<br> `pl_from` int(8) unsigned NOT NULL default '0',<br> `pl_namespace` int(11) NOT NULL default '0',
<br> `pl_title` varchar(255) binary NOT NULL default '',<br> KEY `pl_from` (`pl_from`,`pl_namespace`)<br>) TYPE=MyISAM AS /* SLOW_OK */<br>SELECT pl_from,<br> pl_namespace,<br> pl_title<br> FROM ruwiki_p.pagelinks;
<br><br>This is the complete copying of a table from readonly database to personal one with some altering on keys, not sufficient I suppose. It looks like if copying like this is much slower than access to the same amount of data in one database.
<br><br>Please, advise.<br><br>Mashiah<br>
