Скачать или смотреть SAS Tutorial | PROC SQL Programming Techniques for SAS Users and Programmers

Structured Query Language (SQL) is a universal language used in data science, data analytics, statistics, data management and other disciplines to access, transform, manipulate and output data stored in SAS data sets, relational databases and tables. Based on Kirk Paul Laflers new PROC SQL: Beyond the Basics Using SAS®, Third Edition book, this SAS tutorial presents core concepts and techniques on how to use PROC SQL as a programming and database language. Attendees learn how to construct powerful and scalable queries; define, access and manipulate data from one or more tables using PROC SQL; subset, order and group data; summarize data down rows and across columns using summary functions; join two or more tables using conventional (equi-joins) and unconventional (left, right and full outer join) methods; apply effective fuzzy matching programming techniques when a tables key(s) are inconsistent or less than reliable; use the SQL-macro interface to create single-value (or aggregate) and value-list (array) macro variables; construct real-world queries including nearest neighbor processing; first, last and between By-group processing; produce customized output using Output Delivery System (ODS); construct powerful and scalable indexes to dynamically access rows of data; and query performance considerations.
