Hi.
I have two identical tables and I want to add the last column of the second table to the first table. But I want to change the variable names.
How do I program it?
Table 1
Group | Setting | Value |
1 | a | 25 |
2 | b | 30 |
3 | c | 45 |
Table 2
Group | Setting | Value |
1 | a | 48 |
2 | b | 59 |
3 | c | 35 |
Final output
Group | Setting | Value 1 | Value 2 |
1 | a | 25 | 48 |
2 | b | 30 | 59 |
3 | c | 45 | 35 |
Thanks.
proc sql;
create table want as
select
coalesce(t1.group,t2.group) as group,
coalesce(t1.setting,t2.setting) as setting,
t1.value as value_1,
t2.value as value_2
from table1 t1
full join table2 t2
on t1.group = t2.group and t1.setting = t2.setting
;
quit;
data want;
merge
table1 (rename=(value=value_1))
table2 (rename=(value=value_2))
;
by group setting;
run;
