Learning SQL. Pages · SQL Server Integration Services (SSIS) Step by Step Tutorials Inside Microsoft SQL Server T-SQL Querying eBook. Learning SQL: Master SQL Fundamentals (2nd ed.) by Alan Beaulieu. Read online, or download in DRM-free EPUB or DRM-free PDF format. SQL (Structured Query Language) is a standard programming language for generating, manipulating, and retrieving information from a relational database.

SQL is optimized to handle datasets with millions—and even billions—of records. Replicate and audit faster. At first, a SQL query looks confusing compared to an Excel spreadsheet.

But once you understand the basics of SQL, spreadsheets are far more difficult to understand. Because you can't read step-by-step instructions that explain how spreadsheets calculate values you have to examine each cell , it's very difficult proofread spreadsheets or check their accuracy.

An entire organization exists to educate people on spreadsheet risk management.

Moreover, it's nearly impossible to understand and extend someone else's work done in a spreadsheet. Extending a SQL query involves only reading a few lines of code.

As I read them, I thought these tutorials were helpful—I grasped the concepts, I understood the basic syntax, and I passed through lessons quickly. The day I started my new job, however, I realized just how little I knew. SQL, like any other language, can't be learned by reading alone—you have to answer real questions using real data.

I only really learned when I had to solve problems by querying an actual database. Unfortunately, working with real data requires access to a database with interesting data, and ideas for questions to explore.

Given that these things are hard to gather on your own, it's no wonder people avoid learning SQL. Rather than simply describing SQL syntax and listing examples of how its used, we show you how explore questions with actual data—and in one click, provide access to database already loaded with data.

Each lesson is written in plain English and doesn't assume any prior programming or statistical knowledge, teaches you how to approach data analysis, and draws from situations we've experienced as data analysts in the tech industry. We'd love any feedback on what to add next, and how to make it better: are any of the current lessons confusing or incomplete?

Are there SQL functions or operations that need more explanation?

Are there techniques for manipulating or analyzing data that you'd like to use SQL for, but aren't sure how? Please let us know at support modeanalytics. There are five levels of difficulty from 1 to 5 , You may see it in second column of exercises list.
