2024/10/29 - Redshift Data API Service - 1 new 4 updated api methods
Changes Adding a new API GetStatementResultV2 that supports CSV formatted results from ExecuteStatement and BatchExecuteStatement calls.
Fetches the temporarily cached result of an SQL statement in CSV format. The ExecuteStatement or BatchExecuteStatement operation that ran the SQL statement must have specified ResultFormat as CSV . A token is returned to page through the statement results.
For more information about the Amazon Redshift Data API and CLI usage examples, see Using the Amazon Redshift Data API in the Amazon Redshift Management Guide .

client.get_statement_result_v2(
Id='string',
NextToken='string'
)
string
[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. A suffix indicates then number of the SQL statement. For example, d9b6c0c9-0747-4bf4-b142-e8883122f766:2 has a suffix of :2 that indicates the second SQL statement of a batch query. This identifier is returned by BatchExecuteStatment , ExecuteStatment , and ListStatements .
string
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.

{'ResultFormat': 'JSON | CSV'}
Runs one or more SQL statements, which can be data manipulation language (DML) or data definition language (DDL). Depending on the authorization method, use one of the following combinations of request parameters:
Secrets Manager - when connecting to a cluster, provide the secret-arn of a secret stored in Secrets Manager which has username and password . The specified secret contains credentials to connect to the database you specify. When you are connecting to a cluster, you also supply the database name, If you provide a cluster identifier ( dbClusterIdentifier ), it must match the cluster identifier stored in the secret. When you are connecting to a serverless workgroup, you also supply the database name.
Temporary credentials - when connecting to your data warehouse, choose one of the following options:
When connecting to a serverless workgroup, specify the workgroup name and database name. The database user name is derived from the IAM identity. For example, arn:iam::123456789012:user:foo has the database user name IAM:foo . Also, permission to call the redshift-serverless:GetCredentials operation is required.
When connecting to a cluster as an IAM identity, specify the cluster identifier and the database name. The database user name is derived from the IAM identity. For example, arn:iam::123456789012:user:foo has the database user name IAM:foo . Also, permission to call the redshift:GetClusterCredentialsWithIAM operation is required.
When connecting to a cluster as a database user, specify the cluster identifier, the database name, and the database user name. Also, permission to call the redshift:GetClusterCredentials operation is required.
