6. Query Examples and Best Practices for Effective Data Retrieval and Analysis

The ExecuteQuery API offers a myriad of possibilities for querying and analyzing data from AWS IoT SiteWise. To help developers get started, let’s dive into some practical examples and best practices for effective data retrieval and analysis.

Example 1: Retrieving Temperature Values for a Specific Boiler Asset

“`markdown
Query: “.. asset_name LIKE ‘Boiler_A%’ AND double_value > 100.5”

This query will retrieve temperature values greater than 100.5 from all assets whose names start with “Boiler_A”.
“`

In this example, we’re using the ExecuteQuery API to filter temperature values based on the asset name and a specific threshold. This allows developers to quickly access relevant data without the need to manually reference asset identifiers.

Example 2: Aggregating Data for Historical Analysis

“`markdown
