Join, merge, fill NULL the void columns of multiples files like sql "LEFT JOIN" by using awk
Hello,
This post is already here but want to do this with another way
Merge multiples files with multiples duplicates keys by filling "NULL" the void columns for anothers joinning files
file1.csv:
file2.csv:
file3.csv:
My desired output is like this, conserve the duplicate key and fill it with the data of anothers files, and the void columns is filling by NULL:
result.csv
I already found code with JOIN but I want to do this with AWK

select a.a1,b.b1,c.c1,d.d1,e.e1

left outer join d on d.z=a.z
inner join a.t=e.t

Hello;
I am posting to get any help on my code that I have been struggling for some time. The project is to join two files each with 80k~180k rows. I want to merge them together by the shared common column. The problem of the shared column is partially matching, not exactly the same.
