- hosts: localhost
  vars_prompt:
  - name: " username"
    prompt: "What is merchant name?"
    private: no
    register: reg_name
  - name: "password"
    prompt:  "Enter password"
    private: yes
    encrypt: "sha256_crypt"
    confirm: yes
    salt_size: 16
    register: s
  tasks:
    - debug:
        var: password
      register: s
    - debug: var=s

- name: update db
      shell : echo -n "insert into database (id, createdDate, updatedDate, username, sharedSecretHash) values (7, strftime('%s', 'now'), strftime('%s', 'now'), "{{ reg_name.stdout }}", "{{ s.stdout }}");" | sqlite3 /tmp/test.db

我用 reg_name.stdout 作为用户名和 s.stdout 作为密码注册了变量，并试图在 sql 查询中应用它，它抛出错误 - var undefined。请提出建议。

在 vars_prompt 中，内容存储在同名变量中（在本例中为用户名和密码）。无需使用属性寄存器。实际上，它被ansible忽略了。

这本剧本对我有用：

- hosts: localhost
  vars_prompt:
  - name: " username"
    prompt: "What is merchant name?"
    private: no
  - name: "password"
    prompt:  "Enter password"
    private: yes
    encrypt: "sha256_crypt"
    confirm: yes
    salt_size: 16
  tasks:
    - debug: var=s

    - name: update db
      shell : echo -n "insert into database (id, createdDate, updatedDate, username, sharedSecretHash) values (7, strftime('%s', 'now'), strftime('%s', 'now'), "{{ username }}", "{{ password }}");" | sqlite3 /tmp/test.db
