Using a simple merge statement andthe ability of the macro facility to access both base SAS andmacro functions, the algorithm compares two SAS data sets and presents the differences in an organized fashion. This can beespecially useful when the same data set is changing over time, such as ...

The COMPARE procedure compares the contents of two SAS data sets, selected variables in different data sets, or variables within the same data set. PROC COMPARE compares two data sets: the base data set and the comparison data set. The procedure determines matching variables and matching observati...
Determines if two compute contexts are equivalent. Usage rxCompareContexts(context1, context2, exactMatch = FALSE) Arguments context1 The first compute context to be compared. context2 The second compute context to be compared. exactMatch
Second is that you need to compare ALL of the identification values from one with all of the other in the second set. A data step approach that might work would be rename the date variables when combining the data sets with SET statement; add a source variable using either the...
you a starting point. So, in this first example, all I am specifying are the two data sets I am comparing, one is the BASE data set and one is the COMPARE data set. PROC COMPARE BASE=in.WA_jul2009 COMPARE=in.WA_feb2010 ;
In my opinion, it is one of those ‘oldies but goodies’ that well-rounded SAS programmers need to know about. It is invaluable for the many situations in which one needs to compare two data sets. For example, consider PROC COMPARE the next time you need… • to evaluate newly ...
Enterprise/tagged command queuing. Simultaneously coordinates multiple sets of storage instructions by reordering them at the storage controller level so that they're delivered to the disk in an efficient way. Concurrent data channels. SAS includes multiple full-duplex data channels, which provides for...
