doc/source/whatsnew/vX.X.X.rstfile if fixing a bug or adding a new feature.The goal of this change is to add an explicit example for how to perform a multi-column join. While the existing Comparison with SQL documentation does mention that
mergesupports multiple columns, it is easy to miss and likely requires more research from the user to implement.The reason the new examples are placed inside the
INNER JOINsection is to continue on from the previous existing "merge()also offers..." example, and are intended to read as notes about functionality, which can apply to subsequentJOINtypes.
