short_description: Add or remove MSSQL databases from a remote host.
description:
- Add or remove MSSQL databases from a remote host.
version_added: "2.2"

login_password:
description:
- The password used to authenticate with
required: false
default: null
login_host:
description:
- Host running the database
required: false
login_port:
description:
- Port of the MSSQL server. Requires login_host be defined as other then localhost if login_port is used
required: false
default: 1433
state:
description:
- The database state
required: false
default: present
choices: [ "present", "absent", "import" ]
target:
description:
- Location, on the remote host, of the dump file to read from or write to. Uncompressed SQL
files (C(.sql)) files are supported.
required: false
autocommit:
