Description

Amazon RDS Data Service

Amazon RDS provides an HTTP endpoint to run SQL statements on an Amazon Aurora Serverless DB cluster. To run these statements, you work with the Data Service API.

For more information about the Data Service API, see Using the Data API for Aurora Serverless in the Amazon Aurora User Guide.

Installing

To install the this package using NPM, simply type the following into a terminal window:

npm install @aws-sdk/client-rds-data

Getting Started

Import

The AWS SDK is modulized by clients and commands in CommonJS modules. To send a request, you only need to import the client(RdsDataServiceClient) and the commands you need, for example BatchExecuteStatementCommand:

//JavaScript
const {
  RdsDataServiceClient,
  BatchExecuteStatementCommand
} = require("@aws-sdk/client-rds-data");
//TypeScript
import {
  RdsDataServiceClient,
  BatchExecuteStatementCommand
} from "@aws-sdk/client-rds-data";

Usage

To send a request, you:

  • Initiate client with configuration (e.g. credentials, region). For more information you can refer to the API reference.
  • Initiate command with input parameters.
  • Call send operation on client with command object as input.
  • If you are using a custom http handler, you may call destroy() to close open connections.
const rDSData = new RdsDataServiceClient({region: 'region'});
//clients can be shared by different commands
const params = {
  resourceArn: /**a string value*/,
  secretArn: /**a string value*/,
  sql: /**a string value*/,
};
const batchExecuteStatementCommand = new BatchExecuteStatementCommand(params);
rDSData.send(batchExecuteStatementCommand).then(data => {
    // do something
}).catch(error => {
    // error handling
})

In addition to using promises, there are 2 other ways to send a request:

// async/await
try {
  const data = await rDSData.send(batchExecuteStatementCommand);
  // do something
} catch (error) {
  // error handling
}
// callback
rDSData.send(batchExecuteStatementCommand, (err, data) => {
  //do something
});

Troubleshooting

When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).

try {
  const data = await rDSData.send(batchExecuteStatementCommand);
  // do something
} catch (error) {
  const metadata = error.$metadata;
  console.log(
    `requestId: ${metadata.requestId}
cfId: ${metadata.cfId}
extendedRequestId: ${metadata.extendedRequestId}`
  );
  /*
The keys within exceptions are also parsed. You can access them by specifying exception names:
    if(error.name === 'SomeServiceException') {
        const value = error.specialKeyInException;
    }
*/
}
