Hello there, how I can merge two files like this
File1
ID
1055
1058
1059
With file2
group |
1 |
2 |
3 |
4 |
5 |
6 |
To get a file that looks like this:
ID group
1055 1
1055 2
1055 3
1055 4
1055 5
1055 6
1058 1
1058 2
1058 3
1058 4
1058 5
1058 6
1059 1
1059 2
1059 3
1059 4
1059 5
1059 6
I tried to create one common variable (common=1) in each file and set it to 1 and than merge the two files by that var but it did not get me what I want.
data test;
merge file1 file2;
by common;
run;
What do I do wrong?
Thank you!
Assuming that you have an issue where the second set is actually somewhat more complex and can't be duplicated with a do loop this would be referred to as a cartesian join where every element of one set is matched with every element of another.
Proc Sql;
create table want as
select File1.*, File2.*
from File1, File2;
quit;
Hi,
Why you need to merge. This can be done in this way:
data File1;
input ID;
datalines;
1055
1058
1059
;
data want;
set File1;
do group=1 to 6;
output;
end;
run;
That was just an example. I have many records in both files, that looks more complicated than 1,2,..6. So I would prefer to merge those two file in a way that each record from the file 1 picked up all records from the file2.
