Question

我有一个名词和形容词的数据库，例如：

id | type    | word  
-----------------------
1  | noun    | apple
2  | noun    | ball
3  | adj     | clammy
4  | noun    | keyboard
5  | adj     | bloody

等...

我想创建一个查询，它会抓取10个随机形容词和10个随机名词并将它们放在一起。

无法做到这一点，这可能吗？

谢谢！

Answer 1

每种类型可以获得10个随机元素，如下所示：

select word from YOUR_TABLE where type = 'noun' order by rand() limit 10;
select word from YOUR_TABLE where type = 'adj' order by rand() limit 10;

然后将它们放在PHP代码中，如下所示：

$phrases = array();

$adj_result  = mysql_query("SELECT word FROM words WHERE type = 'adj' ORDER BY RAND() LIMIT 10");
$noun_result = mysql_query("SELECT word FROM words WHERE type = 'noun' ORDER BY RAND() LIMIT 10");

while($adj_row = mysql_fetch_assoc($adj_result)) {
  $noun_row = mysql_fetch_assoc($noun_result);
  $phrases[$adj_row['word']] = $noun_row['word'];
}

print_r($phrases);

请注意，此代码不是很安全（它假设第二个查询的结果总是少于第一个），但是你明白了。

编辑：这是一个应该执行的SQL查询：

select t1.word, t2.word 
from 
  ((select word from YOURTABLE where type = 'adj' order by rand()) as t1), 
  ((select word from YOURTABLE where type = 'noun' order by rand()) as t2) 
order by rand()
limit 10;
