Проблема
Исключение следующего вида:
Неперехваченное исключение
Ошибка: The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET SQL_MAX_JOIN_SIZE=# if the SELECT is okay.
Sql query: SELECT STRAIGHT_JOIN SQL_CALC_FOUND_ROWS SQL_CACHE DISTINCT h.id FROM cms3_hierarchy h, cms3_objects o , cms3_object_content c1, cms3_object_content c2, cms3_object_content c3, cms3_object_content c4, cms3_object_content c5, cms3_object_content c6 ,cms3_permissions c3p WHERE h.obj_id = o.id AND h.is_deleted = '0' AND ((c1.obj_id = o.id AND c1.field_id = '9042' AND c1.float_val BETWEEN '0' AND '150000') AND (c2.obj_id = o.id AND c2.field_id = '9044' AND c2.float_val BETWEEN '0' AND '400') AND (c3.obj_id = o.id AND c3.field_id = '9028' AND (c3.int_val IN ('1'))) AND (c4.obj_id = o.id AND c4.field_id = '9030' AND (c4.int_val IN ('1'))) AND (c5.obj_id = o.id AND c5.field_id = '9033' AND (c5.int_val IN ('1'))) AND (c6.obj_id = o.id AND c6.field_id = '9035' AND (c6.int_val IN ('1')))) AND h.rel IN ('23045') AND h.is_active = '1' AND h.type_id IN ('6') AND ((c3p.owner_id = '2374' AND c3p.rel_id = h.id AND level >= 1) OR (c3p.owner_id = '2373' AND c3p.rel_id = h.id AND level >= 1) OR (c3p.owner_id = '2373' AND c3p.rel_id = h.id AND level >= 1)) ORDER BY h.ord LIMIT 0, 10
Решение
Требуется сделать то, что просят необходимо в файл mysql.php добавть следующую строку:
mysql_query("SET SQL_BIG_SELECTS=1");
<?php
error_reporting(~E_ALL);
/* UMI.CMS mySQL - connection to database */
mysql_connect('rv.mysql', 'rv_mysql', 'rcijhzvy') or die(mysql_fatal());
mysql_select_db('rv_vestiyug') or die(mysql_fatal());
mysql_query("SET NAMES utf8_general_ci");
mysql_query("SET CHARSET utf8");
mysql_query("SET CHARACTER SET utf8");
mysql_query("SET SESSION collation_connection = 'utf8_general_ci'");
// именно эта стока решает проблему
mysql_query("SET SQL_BIG_SELECTS=1");
?>
