[ aws . rds ]



Returns the detailed parameter list for a particular DB parameter group.

See also: AWS API Documentation

describe-db-parameters is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Parameters


--db-parameter-group-name <value>
[--source <value>]
[--filters <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]


--db-parameter-group-name (string)

The name of a specific DB parameter group to return details for.


  • Must be 1 to 255 alphanumeric characters
  • First character must be a letter
  • Cannot end with a hyphen or contain two consecutive hyphens

--source (string)

The parameter types to return.

Default: All parameter types returned

Valid Values: user | system | engine-default

--filters (list)

This parameter is not currently supported.

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

    "Name": "string",
    "Values": ["string", ...]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

--page-size (integer)

The size of each page.

--max-items (integer)

The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination. This NextToken response element should not be used directly outside of the AWS CLI.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
