Also, we can recode “R05” to “R04” inside theĭatastep. We can fix theĬolumn names with the “rename” parameter, and exclude rows with a Let’s try one last time to fix the above issues. It appears this value was coded incorrectly. The region value “R05” is in the stores dataset, but not in the.The “Name” field appeared in both datasets, and was thereforeĪppended with suffixes to distinguish them. Now SAS provides a Structured Query Language (SQL) facility which also merges files.# Merge operation - Outer Join res 1 0 # 6 R04 NA South 0 1 We’ll examine two key topics that most users are confronted with when working with their tables of data, conditional logic scenarios and merges/joins. In the example above, the “Tot”, “Mean”, and “Top” columns were allĬalculated using the datastep array. This paper illustrates the similarities and differences between the Base-SAS® software DATA step merge and PROC SQL join techniques. An empty indexer will return all the values in the You can use the indexer to extract a single value or a The array has an indexer toĮxtract values. This example illustrates how to create row totals, row means, andįind the top month using a data step array.
