Mysql 使用have、GROUP BY和GROUP_CONCAT计算SQL,mysql,sql,Mysql,Sql,如何计算此SQL中的行数。我需要的正是SQL查询而不是PHP函数 SELECT `main_table`.`entity_id`, `main_table`.`supplier_id`, `main_table`.`exported_at`, `main_table`.`created_at`, `main_table`.`updated_at`, `main_table`.`product_id`, `main_table`.`external_id`, GROUP_CONCAT(DISTIN

您可以通过以下方式完成：

因此，您只需包装另一个select，在其中围绕实际select计算行数

因此，在你的情况下：

SELECT COUNT(*) FROM (

一种简单的方法是将整个查询作为一个子查询，用

selectcount（1）FROM（）包装：
