A CTE is just a “virtual table right?
But here’s what many miss
CTEs don’t just exist for readability.
You can JOIN them with actual (physical) tables just like regular tables.
That means you can:
• Simplify complex queries
• Break logic into steps

In my honest opinion, I think cleaning data with SQL is very stressful compared to Python and Excel. Or is there anyone who found SQL easier than Python and excel? I spent like 3 hours cleaning data with SQL today; maybe it's because it's my first time.

¿SQL lento?
En Databricks usa Z-Order para columnas de alta cardinalidad:
OPTIMIZE ... ZORDER BY (columna)
Lee menos archivos y acelera tus consultas.
Partición = baja cardinalidad
Z-Order = alta cardinalidad

Small changes in a query can lead to very different results.
That’s why clarity matters more than complexity.
