Compare SQL datasets

This workflow compares 2 datasets from a single database. Two SQL nodes create a slightly different summary report based on the payments table. Both reports have the same structure, but different time periods. In addition to that, output from the "Orders from 2004 and 2005" node has an extra manipulation on the ordercount variable. This makes Compare Datasets node to produce four outputs: data in A Only Branch, in B Only Branch, Same Branch records and Different Branch records. Please refere to the MySQL Tutorial website and download the example database: https://www.mysqltutorial.org/mysql-sample-database.aspx

Help me set up the n8n workflow "Compare SQL datasets" (https://n8n.io/workflows/1944). It uses: MySQL. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
