Overview

An API client for RDSDataService. To construct a client, you need to configure a :region and :credentials.

client = Aws::RDSDataService::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::SharedCredentials - Used for loading static credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

    • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

    • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

    • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]
    • The :access_key_id, :secret_access_key, and :session_token options.
    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    • ~/.aws/credentials
    • ~/.aws/config
    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentails or Aws::ECSCredentials to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED'] to true.
  • :region (required, String) —

    The AWS region to connect to. The configured :region is used to determine the service :endpoint. When not passed, a default :region is searched for in the following locations:

Instance Method Details

#batch_execute_statement(params = {}) ⇒ Types::BatchExecuteStatementResponse

Runs a batch SQL statement over an array of data.

You can run bulk update and insert operations for multiple records using a DML statement with different parameter sets. Bulk operations can provide a significant performance improvement over individual insert and update operations.

If a call isn't part of a transaction because it doesn't include the transactionID parameter, changes that result from the call are committed automatically.

There isn't a fixed upper limit on the number of parameter sets. However, the maximum size of the HTTP request submitted through the Data API is 4 MiB. If the request exceeds this limit, the Data API returns an error and doesn't process the request. This 4-MiB limit includes the size of the HTTP headers and the JSON notation in the request. Thus, the number of parameter sets that you can include depends on a combination of factors, such as the size of the SQL statement and the size of each parameter set.

The response size limit is 1 MiB. If the call returns more than 1 MiB of response data, the call is terminated.

Examples:

    ({})

Options Hash (params):

  • :resource_arn (required, String) —

    The Amazon Resource Name (ARN) of the Aurora Serverless DB cluster.

  • :secret_arn (required, String) —

    The ARN of the secret that enables access to the DB cluster. Enter the database user name and password for the credentials in the secret.

    For information about creating the secret, see Create a database secret.

  • :sql (required, String) —

    The SQL statement to run. Don't include a semicolon (;) at the end of the SQL statement.

  • :database (String) —

    The name of the database.

  • :schema (String) —

    The name of the database schema.

    The SQL statement is executed as many times as the number of parameter sets provided. To execute a SQL statement with no parameters, use one of the following options:

    • Specify one or more empty parameter sets.

    • Use the ExecuteStatement operation instead of the BatchExecuteStatement operation.

    Array parameters are not supported.

  • :transaction_id (String) —

  req.send_request(options)
end

#begin_transaction(params = {}) ⇒ Types::BeginTransactionResponse

Starts a SQL transaction.

A transaction can run for a maximum of 24 hours. A transaction is terminated and rolled back automatically after 24 hours.

A transaction times out if no calls use its transaction ID in three minutes. If a transaction times out before it's committed, it's rolled back automatically.

DDL statements inside a transaction cause an implicit commit. We recommend that you run each DDL statement in a separate ExecuteStatement call with continueAfterTimeout enabled.

#execute_statement(params = {}) ⇒ Types::ExecuteStatementResponse

Runs a SQL statement against a database.

If a call isn't part of a transaction because it doesn't include the transactionID parameter, changes that result from the call are committed automatically.

If the binary response data from the database is more than 1 MB, the call is terminated.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :resource_arn (required, String) —

    The Amazon Resource Name (ARN) of the Aurora Serverless DB cluster.

  • :secret_arn (required, String) —

    The ARN of the secret that enables access to the DB cluster. Enter the database user name and password for the credentials in the secret.

    For information about creating the secret, see Create a database secret.

  • :sql (required, String) —

    The SQL statement to run.

  • :database (String) —

    The name of the database.

  • :schema (String) —

    The name of the database schema.

    Currently, the schema parameter isn't supported.

  • :parameters (Array<Types::SqlParameter>) —

    The parameters for the SQL statement.

    Array parameters are not supported.

  • :transaction_id (String) —

    The identifier of a transaction that was started by using the BeginTransaction operation. Specify the transaction ID of the transaction that you want to include the SQL statement in.

    If the SQL statement is not part of a transaction, don't set this parameter.

  • :include_result_metadata (Boolean) —

    A value that indicates whether to include metadata in the results.

  • :continue_after_timeout (Boolean) —

    A value that indicates whether to continue running the statement after the call times out. By default, the statement stops running when the call times out.

    For DDL statements, we recommend continuing to run the statement after the call times out. When a DDL statement terminates before it is finished running, it can result in errors and possibly corrupted data structures.

  • :result_set_options (Types::ResultSetOptions) —

    Options that control how the result set is returned.

  • :format_records_as (String) —

    A value that indicates whether to format the result set as a single JSON string. This parameter only applies to SELECT statements and is ignored for other types of statements. Allowed values are NONE and JSON. The default value is NONE. The result is returned in the formattedRecords field.

    For usage information about the JSON format for result sets, see Using the Data API in the Amazon Aurora User Guide.

Returns:

#rollback_transaction(params = {}) ⇒ Types::RollbackTransactionResponse

Performs a rollback of a transaction. Rolling back a transaction cancels its changes.

Examples:

Request syntax with placeholder values


resp = client.rollback_transaction({

})

Response structure
