I have a table:
+--------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------+------------------+------+-----+---------+----------------+
| idurl | int(11) | NO | PRI | NULL | auto_increment |
| idsite | int(10) unsigned | NO | MUL | NULL | |
| url | varchar(2048) | NO | | NULL | |
+--------+------------------+------+-----+---------+----------------+
the select statement is:
SELECT idurl,
url
FROM URL
WHERE idsite = 34
AND url REGEXP '^https\\://www\\.domain\\.com/checkout/step_one\\.php.*'
The query needs 5 seconds on a table with 1000000 rows. Can I achieve a speedup with indexes or something else?
