Merge and SQL are NOT the solution, they are only tools which may be useful, when used in the right way. An Introduction to SAS® Hash Programming Techniques Kirk Paul Lafler, Software Intelligence Corporation, Spring Valley, California Abstract SAS® users are always interested in learning techniques that will help them improve the performance of table lookup, search, and sort operations.

The SAS Output a SAS data set, and also compare the performance of a merge between two datasets once without using index and once with using index. Now SAS provides a Structured Query Language (SQL) facility which also merges files. “one_to_many” or “1:m”: check if merge keys are unique in left dataset. Lots of good things come from the SAS Global Forum! SAS is on the brink of generation change. However, since data may not be stored in a format required for a particular analysis and/or mode of presentation, another set of SAS tools SAS ® PROGRAM EFFICIENCY FOR BEGINNERS Bruce Gilsen, Federal Reserve Board INTRODUCTION This paper presents simple efficiency techniques that can benefit inexperienced SAS ® software users on all SAS data sets, mergingdefinition Merging combines observations from two or more SAS data sets into a single observation in a new data set. In your case, sas kept variables comming from table A. If you want to do it in data step, you need to create many data sets from one of your data sets, within each of them ID should be unique. PDF Combine Pro is powerful but still easy-to-use. merge command followed by a list of key variable(s) and data set(s).
