如何获得mysql随机整数范围?

How to get mysql random integer range?(如何获得mysql随机整数范围?)

问题描述

我正在尝试为我在 1 到 60 之间选择作为计时器的每一行生成一个随机整数.

I am trying to generate a random integer for each row I select between 1 and 60 as timer.

SELECT downloads.date, products.*, (FLOOR(1 + RAND() * 60)) AS timer

我已经搜索并不断提出这个 FLOOR 函数，以了解如何在一个范围内选择一个随机整数.这给了我每一行的 1.我错过了什么?

I have searched and keep coming up to this FLOOR function as how to select a random integer in a range. This is giving me a 1 for every row. What am I missing?

我使用的是 mysql 5.0.75

I am on mysql 5.0.75

这是我认为可能是嵌套问题的其余查询

Heres the rest of the query I belive it might be a nesting issue

SELECT *
FROM (
 SELECT downloads.date, products.*, FLOOR(1 + (RAND() * 60)) AS randomtimer, 
 (
 SELECT COUNT( * )
 FROM distros
 WHERE distros.product_id = products.product_id
 ) AS distro_count,

 (SELECT COUNT(*) FROM downloads WHERE downloads.product_id = products.product_id) AS true_downloads

 FROM downloads
 INNER JOIN products ON downloads.product_id = downloads.product_id
) AS count_table
WHERE count_table.distro_count > 0
AND count_table.active = 1
ORDER BY count_table.randomtimer , count_table.date DESC LIMIT 10

推荐答案

这对我有用.你的mysql版本可能吗?

This is working for me. Your mysql version maybe?

SELECT id, (FLOOR( 1 + RAND( ) *60 )) AS timer
FROM users
LIMIT 0 , 30
