SAS SQL
The SQL procedure is SAS’ implementation of Structured Query Language. PROC
SQL is part of Base SAS software, and you can use it with any SAS data set (table).
Often, PROC SQL can be an alternative to other SAS procedures or the DATA step. You
can use SAS language elements such as global statements, data set options, functions,
informats, and formats with PROC SQL just as you can with other SAS procedures.
