Redshift Data API Service

2020/09/09 - Redshift Data API Service - 9 new api methods

Changes  The Amazon Redshift Data API is generally available. This release enables querying Amazon Redshift data and listing various database objects.

GetStatementResult (new) Link ¶

Fetches the temporarily cached result of an SQL statement. A token is returned to page through the statement results.

See also: AWS API Documentation

Request Syntax

client.get_statement_result(
    Id='string',
    NextToken='string'
)
type Id

string

param Id

[REQUIRED]

The identifier of the SQL statement whose results are to be fetched. This value is a universally unique identifier (UUID) generated by Amazon Redshift Data API. This identifier is returned by ExecuteStatment and ListStatements .

type NextToken

string

param NextToken

A value that indicates the starting point for the next set of response records in a subsequent request. If a value is returned in a response, you can retrieve the next set of records by providing this returned NextToken value in the next NextToken parameter and retrying the command. If the NextToken field is empty, all response records have been retrieved for the request.
