Using Proc SQL and ODBC to Manage Data Outside of SAS® Jeff Magouirk, National Jewish Medical and Research Center, Denver, Colorado
Using Proc SQL and ODBC to Manage Data outside of SAS® Jeff Magouirk, National Jewish Medical and Research Center, Denver, Colorado ABSTRACT The ability to use Proc SQL and ODBC to manage data outside of SAS is another feature in SAS’s toolbox that programmers use to accomplish many different tasks. The idea of pulling data from sources outside of SAS is behind both of these tools. A key benefit of using ODBC and to a certain amount Proc SQL is the reduction in coding that is written. Another positive aspect of using Proc SQL and ODBC is the ability to manage data across a network. At National Jewish Medical & Research Center ODBC and Proc SQL are used to manage and pull end users data across networks so users can examine their data quickly and efficiently. Since end users can have almost real time access to the collected data it is especially useful for checking the accuracy of the data from patient health studies and clinical trials. Error checks and data handling are done first as the data is collected and put into data tables with SAS and then outputted either with an ODBC connection or Proc SQL. The purpose of this paper is to show users how to set up an ODBC connection, compare the reduction in code when an ODBC is set up and how to use Proc SQL to manage data outside of SAS. INTRODUCTION Open Database Connectivity (ODBC) is an Application Programming Interface (API) that allows a programmer to access data from database management system with a non-native application. -
