get-query-results¶
Description¶
Streams the results of a single query execution specified by QueryExecutionId from the Athena query results location in Amazon S3. For more information, see Query Results in the Amazon Athena User Guide . This request does not execute the query but returns results. Use StartQueryExecution to run a query.
If the original query execution ran using an ResultConfiguration$ExpectedBucketOwner setting, the setting also applies to Amazon S3 read operations when GetQueryResults is called. If an expected bucket owner has been specified and the query results are in an Amazon S3 bucket whose owner account ID is different from the expected bucket owner, the GetQueryResults call fails with an Amazon S3 permissions error.
To stream query results successfully, the IAM principal with permission to call GetQueryResults also must have permissions to the Amazon S3 GetObject action for the Athena query results location.
Warning
IAM principals with permission to the Amazon S3 GetObject action for the query results location are able to retrieve query results from Amazon S3 even if permission to the GetQueryResults action is denied. To restrict user or role access, ensure that Amazon S3 permissions to the Athena query location are denied.

See ‘aws help’ for descriptions of global parameters.
get-query-results 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: ResultSet.Rows
Synopsis¶
get-query-results
--query-execution-id <value>
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
Options¶
--query-execution-id (string)
The unique ID of the query execution.
--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.
--starting-token (string)
A token to specify where to start paginating. This is the
NextTokenfrom a previously truncated response.For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--page-size (integer)
The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.
For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--max-items (integer)
The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a
NextTokenis provided in the command’s output. To resume pagination, provide theNextTokenvalue in thestarting-tokenargument of a subsequent command. Do not use theNextTokenresponse element directly outside of the AWS CLI.For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--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.
Examples¶
To return the results of a query
The following get-query-results example returns the results of the query that has the specified query ID.
aws athena get-query-results \
--query-execution-id a1b2c3d4-5678-90ab-cdef-EXAMPLE11111
