MYSQL查询中的两个计数

[英]Two Counts in a MYSQL Query

Hi I have a mysql query which counts the rows in the table for pagination, but I also need to count and group by another column. 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。

I can get the Query to group the records and show correct results, but it stops the pagination from working. 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。

This is my Query 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

Any pointers would be appreciated 任何指针将不胜感激

Try like 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

And you need to give $page value as the current page number and $limit will be the limit that one page contains 并且您需要提供$page值作为当前页码,而$limit将是一页包含的限制
