community.mysql.mysql_query module – Run MySQL or MariaDB queries

Note

This module is part of the community.mysql collection (version 3.11.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.mysql. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: community.mysql.mysql_query.

New in community.mysql 0.1.0

Synopsis

• Runs arbitrary MySQL or MariaDB queries.

• Pay attention, the module does not support check mode! All queries will be executed in autocommit mode.

• To run SQL queries from a file, use community.mysql.mysql_db module.

Requirements

The below requirements are needed on the host that executes this module.

• PyMySQL (Python 2.7 and Python 3.x)

Parameters

Parameter	Comments
ca_cert aliases: ssl_ca path	The path to a Certificate Authority (CA) certificate. This option, if used, must specify the same certificate as used by the server.
check_hostname boolean added in community.mysql 1.1.0	Whether to validate the server host name when an SSL connection is required. Corresponds to MySQL CLIs --ssl switch. Setting this to false disables hostname verification. Use with caution. Requires pymysql >= 0.7.11. Choices: false true
client_cert aliases: ssl_cert path	The path to a client public key certificate.
client_key aliases: ssl_key path	The path to the client private key.
config_file path	Specify a config file from which user and password are to be read. The default config file, ~/.my.cnf, if it exists, will be read, even if config_file is not specified. The default config file, ~/.my.cnf, if it exists, must contain a [client] section as a MySQL connector requirement. To prevent the default config file from being read, set config_file to be an empty string. Default: "~/.my.cnf"
connect_timeout integer	The connection timeout when connecting to the MySQL server. Default: 30
login_db string	Name of database to connect to and run queries against.
login_host string	Host running the database. In some cases for local connections the login_unix_socket=/path/to/mysqld/socket, that is usually /var/run/mysqld/mysqld.sock, needs to be used instead of login_host=localhost. Default: "localhost"
login_password string	The password used to authenticate with.
login_port integer	Port of the MySQL server. Requires login_host be defined as other than localhost if login_port is used. Default: 3306
login_unix_socket string	The path to a Unix domain socket for local connections. Use this parameter to avoid the Please explicitly state intended protocol error.
login_user string	The username used to authenticate with.
named_args dictionary	Dictionary of key-value arguments to pass to the query. Mutually exclusive with positional_args.
positional_args list / elements=any	List of values to be passed as positional arguments to the query. Mutually exclusive with named_args.
query any / required	SQL query to run. Multiple queries can be passed using YAML list syntax. Must be a string or YAML list containing strings. If you use named_args or positional_args any % will be interpreted as a formatting character. All literal % characters in the query should be escaped as %%. Note that if you use the IF EXISTS/IF NOT EXISTS clauses in your query and mysqlclient or PyMySQL 0.10.0+ connectors, the module will report that the state has been changed even if it has not. If it is important in your workflow, use the PyMySQL 0.9.3 connector instead.
single_transaction boolean	Where passed queries run in a single transaction (yes) or commit them one-by-one (no). Choices: false ← (default) true

Attributes

Attribute	Support	Description
check_mode	Support: none	Can run in check_mode and return changed status prediction without modifying target.

Notes

Note

• Compatible with MariaDB or MySQL.

• Requires the PyMySQL (Python 2.7 and Python 3.X) package installed on the remote host. The Python package may be installed with apt-get install python-pymysql (Ubuntu; see ansible.builtin.apt) or yum install python2-PyMySQL (RHEL/CentOS/Fedora; see ansible.builtin.yum). You can also use dnf install python2-PyMySQL for newer versions of Fedora; see ansible.builtin.dnf.

• Be sure you have PyMySQL library installed on the target machine for the Python interpreter Ansible discovers. For example if ansible discovers and uses Python 3, you need to install the Python 3 version of PyMySQL. If ansible discovers and uses Python 2, you need to install the Python 2 version of PyMySQL.

• If you have trouble, it may help to force Ansible to use the Python interpreter you need by specifying ansible_python_interpreter. For more information, see https://docs.ansible.com/ansible/latest/reference_appendices/interpreter_discovery.html.

• Both login_password and login_user are required when you are passing credentials. If none are present, the module will attempt to read the credentials from ~/.my.cnf, and finally fall back to using the MySQL default login of ‘root’ with no password.

• If there are problems with local connections, using login_unix_socket=/path/to/mysqld/socket instead of login_host=localhost might help. As an example, the default MariaDB installation of version 10.4 and later uses the unix_socket authentication plugin by default that without using login_unix_socket=/var/run/mysqld/mysqld.sock (the default path) causes the error ``Host ‘127.0.0.1’ is not allowed to connect to this MariaDB server``.

• If credentials from the config file (for example, /root/.my.cnf) are not needed to connect to a database server, but the file exists and does not contain a [client] section, before any other valid directives, it will be read and this will cause the connection to fail, to prevent this set it to an empty string, (for example config_file: '').

• To avoid the Please explicitly state intended protocol error, use the login_unix_socket argument, for example, login_unix_socket: /run/mysqld/mysqld.sock.

• Alternatively, to avoid using login_unix_socket argument on each invocation you can specify the socket path using the `socket` option in your MySQL config file (usually ~/.my.cnf) on the destination host, for example socket=/var/lib/mysql/mysql.sock.

Examples

# If you encounter the "Please explicitly state intended protocol" error,
# use the login_unix_socket argument

    login_db: acme
    query: SELECT * FROM orders
    login_unix_socket: /run/mysqld/mysqld.sock

- name: Select query to db acme with positional arguments
  community.mysql.mysql_query:
    login_db: acme
    query: SELECT * FROM acme WHERE id = %s AND story = %s
    positional_args:
    - 1
    - test

- name: Select query to test_db with named_args
  community.mysql.mysql_query:
    login_db: test_db
    query: SELECT * FROM test WHERE id = %(id_val)s AND story = %(story_val)s
    named_args:
      id_val: 1
      story_val: test

- name: Run several insert queries against db test_db in single transaction
  community.mysql.mysql_query:
    login_db: test_db
    query:
    - INSERT INTO articles (id, story) VALUES (2, 'my_long_story')
    - INSERT INTO prices (id, price) VALUES (123, '100.00')
    single_transaction: true

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key	Description
executed_queries list / elements=string	List of executed queries. Returned: always Sample: ["SELECT * FROM bar", "UPDATE bar SET id = 1 WHERE id = 2"]
query_result list / elements=string	List of lists (sublist for each query) containing dictionaries in column:value form representing returned rows. Returned: changed Sample: [[{"Column": "Value1"}, {"Column": "Value2"}], [{"ID": 1}, {"ID": 2}]]
