SQL is ubiquitous, but it's also complicated, difficult, and error prone. In this video, C.J. Date -- the world's best-known relational advocate -- shows you how to write SQL code that's logically correct, how to avoid various SQL traps and pitfalls, and, more generally, how to use SQL as if it were a true relational language.
What makes SQL so complicated? Duplicate rows and nulls provide two obvious examples, but they're not the only ones. With C.J. Date's clear and concise instruction, you'll learn relational theory, how SQL departs from the theory, and how to avoid the problems that can cause.
