php mysql 将多个相同的查询合并为一个

Question

所以我有一些从 1 到 40 的范围，

我必须使用它来执行来自相同表和列但来自不同范围的不同查询，例如:

mysql_query("SELECT * FROM table WHERE column > 1 && column <= 15");
mysql_query("SELECT * FROM table WHERE column >=18 && column <= 30");
mysql_query("SELECT * FROM table WHERE column >= 35 && column <= 38");

对于不同的操作，我从这些查询中一一获取总行数...但是我如何将这 3 个示例查询合并为 1 个并获得相同的结果？

Answer 1

SELECT * FROM table 
WHERE (column > 1 AND column <= 15) 
OR (column >= 18 AND column <= 30) 
OR (column >= 35 AND column <= 38)

//编辑:OP 想要计算每个条件的行数:

SELECT 
(SELECT COUNT(*) FROM table WHERE column > 1 AND column <= 15) AS count_1, 
(SELECT COUNT(*) FROM table WHERE column >= 18 AND column <= 30) AS count_2, 
(SELECT COUNT(*) FROM table WHERE column >= 35 AND column <= 38) AS count_3 
FROM table

count_1、count_2 和 count_3 是每个条件的行数。
