SQL - Structured Query Language
For database analyses
In SAS
• PROC SQL
• Designed to run interactively (end with QUIT;)
• Tables are stored as SAS datasets
So we’ll need a LIBNAME statement to connect
to the directory holding the SAS datasets
(*.sas7bdat)
PROC SQL syntax/structure
PROC SQL options ;
SELECT variables
FROM tablenames
WHERE data satisfies condition(s)
GROUP BY group variable(s)
HAVING satisfying grouping condition
ORDER BY sorting variables (DESC) ;
QUIT;
