Comment 4 for bug 1455098

As a temporary solution, we use temporary tables:

1) CREATE TEMPORARY TABLE __ip_test_table_tmp (
              `ip_use` int(10) unsigned NOT NULL,
              `from_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
              `to_time` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
              `bytes` bigint(20) unsigned NOT NULL,
              `dayofweek` tinyint(3) unsigned NOT NULL,
              PRIMARY KEY (`from_time`,`ip_use`,`dayofweek`)
        ) ENGINE=Memory;

2) LOAD DATA LOCAL INFILE '/tmp/dumps/iul.dump' INTO TABLE __ip_test_table_tmp;
3) REPLACE INTO ip_test_table SELECT * FROM __ip_test_table_tmp;
4) DROP TABLE IF EXISTS __ip_test_table_tmp;
