Abstract:
Three basic themes intertwine throughout the Structured Query Language (SQL). SQL statements provide a convenient way to translate the traditional logic of relations among data items to a form closer to machine languages. The structure of a SQL statement a
dheres to patterns that contain variations on the same patterns. SQL syntax makes the most of a few key terms. This sequel to 'Ten Good Reasons to Learn SAS(R) SQL' will review the advantages of more logical, structured, and simpler programming languages,
but, unlike its predecessor, recognize that most beginning programmers who are learning SAS(R) already know the critical elements of SAS(R) SQL. This gentle introduction to SAS(R) SQL will help beginning programmers understand the foundations of a pragmati
c, robust, and extensible programming method.
