![]() In normal 7-Bit ASCII the printable characters are between ! ('21'x or 33 decimal) and ~ ('7E'x or 126 decimal). INTRODUCTION Anyone who has spent much time programming with SAS has likely found themselves needing to combine data from multiple datasets into a single dataset. That will get rid of tabs, non-breaking spaces, nulls and other strange things. I like to eliminate anything that is not a normal 7-bit ASCII code. Also you can compress more than just spaces from the values. In your clean up data steps you should force the length of the variables to be consistent. Also make sure you haven't attached a format to one of the datasets so that the values you see printed are not what is actually in the data. ![]() Make sure that the values do not have leading spaces or other non-printing characters.

Portland, OR The use of multiple set statements in a data step is little known and often misunderstood. If they are character then make sure the values are consistent in their use of upper and lower case letters. Multiple Set Statements in a Data Step: A Powerful Technique for Combining and Aggregating Complex Data Renu Gehring ABSTRACT SAS Instructor Ace-Cube, LLP Beaverton, OR Health Care Analyst CareOregon, Inc. Records from both datasets are included, so if none of the keys match then the result will be the same as if you used SET instead of MERGE.Īre you sure that there is any overlap between the two sets of data? Check that your variables are the same length. Your code is the correct format for merging by multiple variables. I realized I can post the code that I meant to deal with potential unwanted spaces here. Does is just make the most sense to code a new unique id by combining the two variables that are shared by both data sets? ![]() The combination of "study_id" and "round" provides a unique identifier, but no one variable does. But it just stacks the two sets creating double the correct number of IDs. I've tried to merge by study_id and round which are the only two variables shared across the data sets. The data looks like this in both data sets: study_id.round.other variables different between the two sets For example, below we have a data file containing information on dads and we have a file containing information on family income called faminc. Each assistant includes end-to-end examples with datasets, plus the ability. I am attempting to merge two data sets without a single key variable. Introduction When you have two data files, you can combine them by merging them side by side, matching up observations based on an identifier. Version 7.0.0 of the Splunk Add-on for AWS includes a merge of.
