DynamoDB: Query Greater Than (Guide w/ Code Examples)

To query a DynamoDB table using the JavaScript SDK and retrieve items where a specific attribute has a value greater than a certain value, you can use the query operation and pass in an object containing the necessary parameters.

const AWS = require('aws-sdk');
const dynamoDb = new AWS.DynamoDB.DocumentClient();

const params = {
    TableName: 'myTable',
    KeyConditionExpression: '#id > :value',
    ExpressionAttributeNames: {
        '#id': 'id',
    },
    ExpressionAttributeValues: {
        ':value': 5
    }
};

dynamoDb.query(params, (error, data) => {
    if (error) {
        console.log(error);
    } else {
        console.log(data.Items);
    }
});
