MYSQL查询中的两个计数

Question

嗨，我有一个mysql查询，它计算表中的行以进行分页，但是我还需要对另一列进行计数和分组。

我可以通过查询对记录进行分组并显示正确的结果，但是它使分页无法正常工作。

这是我的查询

SELECT 
   COUNT(*) as num, 
   COUNT (search_term)  
FROM $tableName 
WHERE client_id = '{$client_id}' 
AND search_term IS NOT NULL 
AND search_term != '' 
GROUP BY search_term

任何指针将不胜感激

Answer 1

尝试像

SELECT COUNT(*) as num1, COUNT (search_term) as num2  
FROM $tableName 
WHERE client_id = '{$client_id}' 
    AND search_term IS NOT NULL 
    AND search_term != '' 
GROUP BY search_term
LIMIT $page , $limit

并且您需要提供$page值作为当前页码，而$limit将是一页包含的限制
