SQL Skills Every Data Analyst Must Learn to Get Hired

Most aspiring analysts in Bangalore make the same mistake: they spend months on Python but only days on SQL. In reality, 90% of technical interviews for data roles start with a SQL screening. In 2026, "knowing SQL" means more than just basic SELECT statements; it means being able to manipulate complex, real-time datasets at scale.

The Top 5 SQL Skills for 2026

• 01

  Advanced Joins & Multi-Table Logic

  Business data never lives in one table. You must be able to join 4-7 tables (Fact vs Dimension) without creating duplicates or performance bottlenecks.

• 02

  Window Functions (Over() Clause)

  Essential for calculating metrics like rolling averages, month-over-month growth, and ranking customers (e.g., RANK(), LAG(), LEAD()).

• 03

  CTEs (Common Table Expressions)

  Modern analysts use WITH clauses to write "Clean SQL." This makes your queries readable, testable, and ready for team collaboration.

• 04

  Performance Optimization

  In 2026, slow queries cost money. You must understand Execution Plans, indexing, and how to filter data early to save cloud compute costs.

• 05

  NoSQL & Cloud Warehousing

  Familiarity with BigQuery, Snowflake, and NoSQL databases like MongoDB is now a "Gold Standard" for Bangalore recruiters.
