DynamoDB: Not Begins With (Guide w/ Code Examples)

The DynamoDB JavaScript SDK does not have a method specifically called "not begins with." However, you can use the scan or query operations with a FilterExpression that uses the not_begins_with method to retrieve items that do not have an attribute that begins with a certain value.

const AWS = require('aws-sdk');
const dynamoDB = new AWS.DynamoDB({region: 'us-west-2', apiVersion: '2012-08-10'});

const params = {
    TableName: 'my-table',
    FilterExpression: 'not_begins_with(attribute, :val)',
    ExpressionAttributeValues: {
        ':val': {S: 'example'}
    }
};

dynamoDB.scan(params, (err, data) => {
    if (err) {
        console.log(err);
    } else {
        console.log(data);
    }
});
