Question

我有两张桌子

表verkoper

表bestellingen

我的查询：

---
- hosts: localhost
  gather_facts: no
  vars:
    git_ssh_public_key: "Your public ssh key"
    git_ssh_key: |
              -----BEGIN RSA PRIVATE KEY-----
              .... actual key here ....
              -----END RSA PRIVATE KEY-----
  tasks:
  - name: Copy SSH public key file
    copy: 
      content: "{{ git_ssh_public_key }}"
      dest: /root/.ssh/id_rsa.pub
      mode: 0644

  - name: Copy SSH private key file
    copy: 
      content: "{{ git_ssh_key }}"
      #src: id_rsa
      dest: /root/.ssh/id_rsa
      mode: 0600

  - name: Get new source from GIT
    git: 
      repo: "git@gitlab.com:user/repo.git"
      dest: "/var/www/"
      depth: 1
      accept_hostkey: yes
      clone: yes

它给了我错误 SELECT v.naam, SUM(COUNT(b.status) * 1.50) FROM verkoper AS v INNER JOIN bestellingen AS b ON b.verkoper = v.id WHERE b.status = 'retour' GROUP BY b.verkoper 有人有想法吗？

Answer 1

我认为这可能是你想要的：

SELECT v.naam, COUNT(*)*1.50
FROM verkoper v INNER JOIN
     bestellingen b
     ON b.verkoper = v.id
WHERE b.status = 'retour'
GROUP BY v.naam;

注意：

• GROUP BY键应与查询中的未聚合列匹配。
• 您可以使用COUNT(*)或COUNT(1)计算所有行数。输入更简单。
• 没有理由将COUNT()嵌入SUM()。
