Learn how to process numerical, text, and other types of data with SQL’s most-used functions.
Introduce yourself to the standard SQL functions used in data processing. This course shows you how to use SQL to work with the following data types:
You’ll also learn about:
You’ll also examine the CASE WHEN expression – a powerful SQL construction that facilitates conditional computations. Finally, the SQL reporting exercises explain how to work with computing ratios and percentages.
Note: This course uses examples written in standard SQL, but not all databases comply with the SQL standard. Some minor modifications may be needed. If that’s the case, we’ll let you know in the exercise instructions. Also, many databases offer non-standard functions that do the same thing as these standard functions. We don’t cover non-standard syntax in this course; your database documentation is a good place to learn about any non-standard syntax.
Plus, you’ll get to practice your skills on 211 interactive exercises.
The material in Standard SQL Functions is intended for intermediate users. To complete this course, you’ll need to know:
This course is not about user-defined functions. If you're looking for a course about user-defined functions, see the Writing User-Defined Functions in PostgreSQL course.
