Query Date Range in DynamoDB Using Java (Guide w/ Code Examples)
Provided by Rafal Wilinski
This example queries the MyTable
table for items where the date
attribute is between one month ago and now. The Calendar
class is used to get the current date and a date one month ago, which are then passed as parameters to the query.
import java.util.Calendar; import java.util.HashMap; import java.util.Map; import com.amazonaws.services.dynamodbv2.AmazonDynamoDB; import com.amazonaws.services.dynamodbv2.AmazonDynamoDBClientBuilder; import com.amazonaws.services.dynamodbv2.model.AttributeValue; import com.amazonaws.services.dynamodbv2.model.Condition; import com.amazonaws.services.dynamodbv2.model.QueryRequest; import com.amazonaws.services.dynamodbv2.model.QueryResult; public class QueryDateRangeExample { public static void main(String[] args) { AmazonDynamoDB client = AmazonDynamoDBClientBuilder.defaultClient(); Calendar calendar = Calendar.getInstance(); java.util.Date now = calendar.getTime(); calendar.add(Calendar.MONTH, -1); java.util.Date oneMonthAgo = calendar.getTime(); Map<String, AttributeValue> attributeValues = new HashMap<>(); attributeValues.put(":start", new AttributeValue().withS(oneMonthAgo.toString())); attributeValues.put(":end", new AttributeValue().withS(now.toString())); QueryRequest queryRequest = new QueryRequest() .withTableName("MyTable") .withKeyConditionExpression("date BETWEEN :start AND :end") .withExpressionAttributeValues(attributeValues); QueryResult result = client.query(queryRequest); result.getItems().forEach(item -> System.out.println(item)); } }
