Mysql 获取不带where子句的非零ID计数

我不想得到非零的漏斗id计数。我得到了漏斗id计数，但也显示了漏斗id的计数为零，在这里我们不添加where子句，在这个查询中我也得到了page_计数

SELECT `smart_projects`.project_id, `smart_projects`.business_id, `smart_projects`.title,
`page_pages`.`funnel_id` as `funnel_id`, count(distinct(page_pages.page_id) )as page_count, count(distinct(page_pages.funnel_id) )as funnel_count
FROM `smart_projects`
LEFT JOIN `page_pages` ON `smart_projects`.`project_id` = `page_pages`.`project_id`
WHERE  smart_projects.status !=  0
AND `smart_projects`.`business_id` = 'cd9412774edb11e9'
AND `smart_projects`.`created_date` BETWEEN 1558031400 AND 1558722600
GROUP BY `smart_projects`.`project_id`
ORDER BY `funnel_count` ASC
 LIMIT 10

page_pages表格为：

smart_项目表为：

结果是：-

预期结果是：

---

如果要过滤掉零值，请使用

having

子句：

SELECT sp.project_id, sp.business_id, sp.title,
       count(distinct pp.page_id ) as page_count, 
       count(distinct pp.funnel_id ) as funnel_count
FROM `smart_projects` sp LEFT JOIN
      `page_pages` pp
      ON sp.`project_id` = pp.`project_id`
WHERE sp.status <>  0 AND
      sp.`business_id` = 'cd9412774edb11e9' AND
      sp.`created_date` BETWEEN 1558031400 AND 1558722600
GROUP BY sp.`project_id`
HAVING funnel_count > 0
ORDER BY `funnel_count` ASC
LIMIT 10;

选择sp.project\u id、sp.business\u id、sp.title、，
计数（不同的pp.page_id）为page_计数，
计数（不同的pp.funnel\u id）作为漏斗计数
来自'smart_projects'sp LEFT JOIN
`第页
在sp.`project\u id`=pp.`project\u id上`
其中sp.status 0和
sp.`business_id`=“cd9412774edb11e9”和
sp.“创建日期”介于1558031400和1558722600之间
按sp.`project_id分组`
漏斗计数大于0
按“漏斗计数”ASC订购
限制10；

注:

• 表别名使查询更易于编写和读取

• DISTINCT

  不是一个函数，而是一个关键字。下面的表达式不需要括号

• funnel\u id

  在

  SELECT

  中不合适，因为它是聚合函数的参数

您的预期结果是什么？此外，我们真的不喜欢带有样本数据的图像-读取常规ascii文本要容易得多。在结果表项目中，id 346漏斗计数应为0。因为漏斗id是0页表格。请在问题中发布该期望值，并给出解释。我添加期望结果。请检查

SELECT `smart_projects`.project_id, `smart_projects`.business_id, `smart_projects`.title,
 `page_pages`.`funnel_id` as `funnel_id`, count(distinct(page_pages.page_id) )as page_count, count(distinct (CASE WHEN page_pages.funnel_id != 0 then  page_pages.funnel_id ELSE NULL END ) ) as funnel_count
FROM `smart_projects`
LEFT JOIN `page_pages` ON `smart_projects`.`project_id` = `page_pages`.`project_id`
WHERE  smart_projects.status !=  0 
AND `smart_projects`.`business_id` = 'cd9412774edb11e9'
GROUP BY `smart_projects`.`project_id`
ORDER BY `title` DESC
