Does a merge statement need a by statement? If not, then when do we use a by statement with the merge statement?

Read the documentation first: https://documentation.sas.com/?docsetId=lestmtsref&docsetTarget=n1i8w2bwu1fn5kn1gpxj18xttbb0.htm&doc...

And if it is still not clear, then ask further questions.

Hi:
And in this previous forum posting: https://communities.sas.com/t5/SAS-Programming/Merge-datasets/td-p/463569 are some images and code to explain merge with BY.

In addition, the documentation has a section that outlines the different way to combine data sets all side by side with code examples.

It's definitely worth a read.
