Run queries

In this lesson, you will learn how to setup, write, and execute queries to validate the data you have ingested.

Adobe Experience Platform Query Service helps you make sense of your data by allowing you to use standard SQL to query data in Platform. Using Query Service, you can join any dataset in the Data Lake and capture the query results as a new dataset for use in reporting, machine learning, or for ingestion into Real-Time Customer Profile.

Data Architects and Data Engineers will need to use query service outside of this tutorial.

Before you begin the exercises, watch this short video to learn more about Query Service:

Simple Queries

Let’s start with some simple queries:

In the Platform user interface, go to Queries in the left navigation
Select the Create Query button on the top right to open a text box to run and execute queries
Enter the following query in the editor and press Shift+Enter or Shift+Return to execute the query.
```
SHOW TABLES
```
This shows the list of available tables
Now try this query, replacing _techmarketingdemos with your own tenant namespace, which, if you recall, is visible in your schemas.
```
SELECT person.name.lastName,loyalty.tier
FROM luma_loyalty_dataset
WHERE loyalty.tier ='gold'
```
If there is any error, detailed messages will appear in the Console tab, as pictured below
With your successful query, Name it Luma Gold Level Customers
Select the Save button
