데이터베이스 설명
다음 코드 조각을 사용하여 새로 생성된 데이터베이스의 속성에 대한 정보를 가져올 수 있습니다.
- Java

public void describeDatabase() { System.out.println("Describing database"); final DescribeDatabaseRequest describeDatabaseRequest = new DescribeDatabaseRequest(); describeDatabaseRequest.setDatabaseName(DATABASE_NAME); try { DescribeDatabaseResult result = amazonTimestreamWrite.describeDatabase(describeDatabaseRequest); final Database databaseRecord = result.getDatabase(); final String databaseId = databaseRecord.getArn(); System.out.println("Database " + DATABASE_NAME + " has id " + databaseId); } catch (final Exception e) { System.out.println("Database doesn't exist = " + e); throw e; } }
- Java v2
-
public void describeDatabase() { System.out.println("Describing database"); final DescribeDatabaseRequest describeDatabaseRequest = DescribeDatabaseRequest.builder() .databaseName(DATABASE_NAME).build(); try { DescribeDatabaseResponse response = timestreamWriteClient.describeDatabase(describeDatabaseRequest); final Database databaseRecord = response.database(); final String databaseId = databaseRecord.arn(); System.out.println("Database " + DATABASE_NAME + " has id " + databaseId); } catch (final Exception e) { System.out.println("Database doesn't exist = " + e); throw e; } }
- Go

- Python
-

다음 조각은 JavaScript v3에 를 사용합니다 AWS SDK. 클라이언트를 설치하는 방법과 사용량에 대한 자세한 내용은 JavaScript v3SDK용 Timestream Write Client - AWS를 참조하세요.
클래스 DescribeDatabaseCommand 및 도 참조하세요DescribeDatabase.
import { TimestreamWriteClient, DescribeDatabaseCommand } from "@aws-sdk/client-timestream-write"; const writeClient = new TimestreamWriteClient({ region: "us-east-1" }); const params = { DatabaseName: "testDbFromNode" }; const command = new DescribeDatabaseCommand(params); try { const data = await writeClient.send(command); console.log(`Database ${data.Database.DatabaseName} has id ${data.Database.Arn}`); } catch (error) { if (error.code === 'ResourceNotFoundException') { console.log("Database doesn't exist."); } else { console.log("Describe database failed.", error); throw error; } }
다음 조각은 JavaScript V2 스타일에 를 AWS SDK 사용합니다. 이는 Node.js 샘플 Amazon Timestream LiveAnalytics 의 샘플 애플리케이션을 기반으로 합니다 GitHub
. async function describeDatabase () { console.log("Describing Database"); const params = { DatabaseName: constants.DATABASE_NAME }; const promise = writeClient.describeDatabase(params).promise(); await promise.then( (data) => { console.log(`Database ${data.Database.DatabaseName} has id ${data.Database.Arn}`); }, (err) => { if (err.code === 'ResourceNotFoundException') { console.log("Database doesn't exist."); } else { console.log("Describe database failed.", err); throw err; } } ); }
- .NET
-
public async Task DescribeDatabase() { Console.WriteLine("Describing Database"); try { var describeDatabaseRequest = new DescribeDatabaseRequest { DatabaseName = Constants.DATABASE_NAME }; DescribeDatabaseResponse response = await writeClient.DescribeDatabaseAsync(describeDatabaseRequest); Console.WriteLine($"Database {Constants.DATABASE_NAME} has id:{response.Database.Arn}"); } catch (ResourceNotFoundException) { Console.WriteLine("Database does not exist."); } catch (Exception e) { Console.WriteLine("Describe database failed:" + e.ToString()); } }
