SQL for Data Analytics Introduction

SQL for Data Analytics

Introduction

Most business data is stored in databases, not spreadsheets. SQL (Structured Query Language) lets analysts ask questions of relational data by:

  • Selecting columns
  • Filtering records
  • Joining related tables
  • Calculating summaries

SQL is one of the most requested skills in analyst job descriptions. It handles millions of rows that would slow a spreadsheet down.

The examples use standard SQL patterns. Details differ across systems:

Notable syntax differences

MySQLWeb applicationsLIMIT, DATE_FORMAT(), no FULL OUTER JOIN
SQL ServerMicrosoft environmentsTOP, DATETRUNC() (2022+)
BigQueryGoogle Cloud analyticsLIMIT, DATE_TRUNC(col, MONTH)
SQLiteLightweight, local practiceLimited date functions

What you will learn in this module

  • How relational tables, rows, columns, and keys work
  • How to retrieve and filter records with SELECT and WHERE
  • How to summarise data with aggregate functions and GROUP BY
  • How to combine tables using joins
  • How to use CASE, subqueries, and common table expressions for practical analysis
