127-29: Efficiency Techniques for Beginning PROC SQL Users
Paper 127-29 Efficiency Techniques for Beginning PROC SQL Users Kirk Paul Lafler, Software Intelligence Corporation Abstract PROC SQL provides SAS Users with a powerful programming language that can rival DATA step coding Techniques either in terms of the processing time or the human time involved to write the code.
