Qwiklabs - Merging Results from Different Explores in Looker [GSP856] | Google Cloud Platform Demo

Explores in Looker are designed by your Looker developers to combine the data from your database tables in the best way, using defined relationships between data fields and tables. Because of this, it is best to use a single Explore to examine your data.

However, there may be times when your Looker developers haven’t created the relationships you need, or they faced technical limitations. In these cases, Looker lets you combine data from different Explores (even from different models or projects) to create data tables and visualizations.

Using the Merged Results feature, you can create a query from an Explore and then add queries from other Explores to display the merged results in a single table. From there, you can examine the data, pivot fields, and create visualizations.

The Merged Results feature has a limit of 5,000 rows of data for each of the merged queries. If you include queries that return more than 5,000 rows of data, only the first 5,000 rows returned are included in the merged results.
When you merge queries, you start out by creating a single query from a single Explore, and then you combine other queries with that first query.

By default, that first query is considered the primary query. This is an important concept because when Looker matches the data to create the merged results, it matches each added query to the primary query (not to any other added query). So, whenever you add a query, you need to include a dimension that can be matched to a dimension in the primary query.
To understand more about merged results, please see documentation about merged results.

Objectives
In this lab, you learn how to merge results from different explores by doing the following:

Create a primary query and a next source query

Check merge results and run a merge

Edit the merged results

Save your merged results to a dashboard
