Options

--query-planning-context (structure)

A structure containing information about the query plan.

CatalogId -> (string)

The ID of the Data Catalog where the partition in question resides. If none is provided, the Amazon Web Services account ID is used by default.

DatabaseName -> (string)

The database containing the table.

QueryAsOfTime -> (timestamp)

The time as of when to read the table contents. If not set, the most recent transaction commit time will be used. Cannot be specified along with TransactionId .

QueryParameters -> (map)

A map consisting of key-value pairs.

key -> (string)

value -> (string)

TransactionId -> (string)

The transaction ID at which to read the table contents. If this transaction is not committed, the read will be treated as part of that transaction and will see its writes. If this transaction has aborted, an error will be returned. If not set, defaults to the most recent committed transaction. Cannot be specified along with QueryAsOfTime .

Shorthand Syntax:

CatalogId=string,DatabaseName=string,QueryAsOfTime=timestamp,QueryParameters={KeyName1=string,KeyName2=string},TransactionId=string

JSON Syntax:

{
  "CatalogId": "string",
  "DatabaseName": "string",
  "QueryAsOfTime": timestamp,
  "QueryParameters": {"string": "string"
    ...},
  "TransactionId": "string"
}

--query-string (string)

A PartiQL query statement used as an input to the planner service.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

QueryId -> (string)

The ID of the plan query operation can be used to fetch the actual work unit descriptors that are produced as the result of the operation. The ID is also used to get the query state and as an input to the Execute operation.
