Hello,
I am trying to find a way to combine two datasets efficiently.
Dataset A contains around 1000 variables (Numeric and Characters) and 20000 obs.
Dataset B contains around 50 variables (Numeric and Characters) and 5000 obs.
Both A and B have the same 5000 IDs. B has 49 columns with the same names as A, and one extra 'Record_updated' column. In addition, B has all the updated records in those 49 columns. I would like to combine A and B with a result, that contains 1001 columns and 20000 obs, including 49 updated B dataset columns, and a new 'Record_updated' column. Please advise how to approach it, thanks.
