You can join two data sets top to bottom, this is appending.</P> Fri, 27 Nov 2020 20:46:06 GMT PaigeMiller 2020-11-27T20:46:06Z https://communities.sas.com/t5/SAS-Certification/Combine-SAS-datasets/m-p/702111#M1083 <P>what is the significance of two kinds of combinations, concatenating and appending? For the forth two datasets are simply integrated in a bigger set and the latter is attached even without creating a new dataset. The second dataset is attached in some cases by Force. Are these two extensively used in practical dataset manipulation?</P> Fri, 27 Nov 2020 20:26:20 GMT https://communities.sas.com/t5/SAS-Certification/Combine-SAS-datasets/m-p/702111#M1083 anming 2020-11-27T20:26:20Z https://communities.sas.com/t5/SAS-Certification/Combine-SAS-datasets/m-p/702112#M1084 <P>You can join two data sets left to right (in various ways), this is concatenating.
