Developers should learn Power Query when working with data analysis, reporting, or business intelligence tasks in Excel or Power BI, as it simplifies data cleaning, merging, and transformation processes meets pick sql when data is relational, reads outnumber writes, and you want decades of query optimizers, hires, and tooling behind you — it's the default for oltp backends, analytics warehouses, and any resume line a hiring manager recognizes on sight. Here's our take.

Power Query

Nice Pick

Developers should learn Power Query when working with data analysis, reporting, or business intelligence tasks in Excel or Power BI, as it simplifies data cleaning, merging, and transformation processes

Pros

• It is particularly useful for automating repetitive data preparation tasks, handling large datasets from multiple sources, and creating dynamic data models that update automatically with new data
• Related to: excel, power-bi

Cons

• Specific tradeoffs depend on your use case

SQL

Pick SQL when data is relational, reads outnumber writes, and you want decades of query optimizers, hires, and tooling behind you — it's the default for OLTP backends, analytics warehouses, and any resume line a hiring manager recognizes on sight

Pros

• Skip it for graph traversals with unpredictable depth (reach for Cypher/Neo4j instead) or schema-less documents you'll reshape weekly (MongoDB)
• Related to: postgresql, mysql

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Power Query is a tool while SQL is a language. We picked Power Query based on overall popularity, but your choice depends on what you're building.

The Bottom Line
