[英]Key press autocomplete queries to a 3 million rows table
I have a table fs_city
, with 3 millions cities all around the world, as well as a table fs_country
. 我有一个表
fs_city
,具有世界各地300万个城市,以及一个表fs_country
。
When the user visits the website it detects its country code, the user is required to select their country and city from a box (which looks for cities in fs_city
on key press), if the user is from USA, and types "Ne", he will get a drop down list with "New York" for ie I do this to create an autocomplete input. 当用户访问它检测到其国家代码的网站时,如果用户来自美国,则要求用户从框中选择其国家和城市(在
fs_city
上查找fs_city
城市),如果用户输入“ Ne”,他将通过“纽约”获得一个下拉列表,例如,我这样做是为了创建自动完成输入。
The problem is that, the query is sent upon every key press, in my example "Ne", there are two queries to the table fs_city
. 问题是,查询是在每次按键时发送的,在我的示例“ Ne”中,对表
fs_city
有两个查询。
Also, even if there's only one query, it takes 6 seconds to return a response from that table... My table has primary keys. 另外,即使只有一个查询,它也需要6秒钟才能从该表返回响应...我的表具有主键。
This is my SQL query: 这是我的SQL查询:
SELECT
ci.city_id,
ci.country_code,
ci.city,
ci.region,
co.country_name
FROM
fs_city as ci,
fs_country as co
WHERE
ci.city LIKE "Ne%"
AND co.country = ci.country_code
AND ci.country_code = :country
ORDER BY
ci.city ASC
LIMIT 0,20
How can I create an autocomplete feature (with keypress), and how to speed up fs_city
table queries? 如何创建自动完成功能(带按键),以及如何加快
fs_city
表查询?
Updated : 更新 :
fs_city primary key : city_id fs_city主键:city_id
fs_country primary key : country_id fs_country主键:country_id

jQuery has nice widget with exactly what you are looking for and I'm pretty sure you can limit it to only start query the database after a set amount of characters so you can limit your results. jQuery具有与您要查找的东西完全一样的漂亮小部件,并且我敢肯定您可以限制它,使其仅在设置一定数量的字符后才开始查询数据库,以便您可以限制结果。 That should solve your speed problem and shorten your javascript.
那应该解决您的速度问题并且缩短您的javascript。 http://jqueryui.com/autocomplete/

EDIT MySQL also has a LIMIT term to cap the return, which might also help. EDIT MySQL还有一个LIMIT项来限制返回值,这也可能有帮助。
