Compare Two SQL Datasets from MySQL
Compares two SQL query results from a MySQL database, identifying matching, differing, unique records across time periods.
This workflow automates the comparison of two datasets extracted from a MySQL payments table using custom SQL queries. One query aggregates orders from 2003-2004 by customerNumber and year, while the second covers 2004-2005 with an additional manipulation on the ordercount field. The Compare Datasets node merges them by customerNumber and year, producing four outputs: records unique to dataset A, unique to B, matching records, and records with differences.
