PROC SQL is a powerful SAS process that allows users to alter and query data using SQL (Structured Query Language). Unlike other SAS procedures, which are generally used for statistical analysis and data manipulation, PROC SQL is intended for database querying operations. It provides greater versatility in terms of data processing, joining, sub setting, and summarising than typical SAS processes. PROC SQL also supports many database administration systems. However, it may have a higher learning curve for users who are unfamiliar with SQL terminology than other SAS processes that only employ the SAS programming language.
