Compare 2 SQL Datasets
Key Features and Highlights
This workflow automates the execution of two SQL queries to retrieve customer order data from different time periods (2003-2004 and 2004-2005). It compares the two datasets based on customer ID and year fields, enabling users to quickly identify trends in order quantities or amounts. Utilizing n8n’s “Compare Datasets” node, the workflow supports multi-condition data matching and multiple matching results, enhancing the accuracy and flexibility of data analysis.
Core Problem Addressed
Comparing customer order data across different years or time periods is a common and critical task in business data analysis. Manual comparison is time-consuming and prone to errors. This workflow automates SQL query execution and data comparison, solving the inefficiencies and complexities of cross-period data comparison, and helps users rapidly detect changes in customer orders.
Application Scenarios
- Financial analysts or business analysts comparing customer order data across different periods
- Sales teams evaluating changes in customer purchasing behavior
- Data teams analyzing historical order data trends
- Any scenario requiring automated comparison of database data across different time frames
Main Process Steps
- Manually trigger the workflow: Start the entire process via the “Execute Workflow” button
- Execute the first SQL query: Retrieve total order amounts and quantities for customers in 2003 and 2004
- Execute the second SQL query: Retrieve total order amounts and quantities for customers in 2004 and 2005
- Adjust data fields: Configure or modify the order quantity field in the second query’s results
- Compare datasets: Perform multi-condition matching based on customer ID and year to find all matching records
- Output comparison results: Provide data for subsequent analysis or processing
