Hello, i have one problem I need to do a join to bring a column from another table and append it to the original one that I have
Example
It should be the same data of the first base, but when I do the join this happens
You haven’t really given us many details to work with.
- What kind of join are you doing?
- What column(s) are you joining on?
- Are adequately specifying the join conditions so that there are no duplicate matches?
- Have you identified any patterns in which rows are being duplicated?

What about the rest of the questions I asked?
I’ll also add the following:
You say that you want the same data as the first table, but your screenshot shows that you’re using a full outer join. What is the logic behind this? The result of an outer join is matched rows as well as unmatched rows from both tables.
