Hi ,
I have two tables Table 1 and Table 2,
need to rollup from table 1 Covunit field value to Table 2 totunits field where rev=N
Table 1:
In table 1, we have ID that has multiple line no.
ID LINENO pos covunit rev
1 1 23 1 N
1 2 23 1 N
1 3 23 1 N
1 4 23 1 N
2 1 23 1 N
2 2 23 1 N
3 3 23 1 N
4 5 23 1 Y
Table 2:
In table 2, the default value for lines is 0.
ID lineNo totunits
1 0
2 0
3 0
4 0
Output should be:
ID lineno Totunits
1 0 4
2 0 2
3 0 1
4 0
Please help me out on this logic.
Thanks in Advance
There are a number of ways to do what you want. The following assumes that table2 is sorted in ID order:
proc freq data=table1 (where=(rev eq 'N'));
tables id*rev/out=sums (keep=ID count
rename=(count=totunits));
run;
data table3;
merge table2 sums;
by id;
run;
Hi ... another idea ...
proc sql;
create table t3 as
select id, lineno, totunits from
(select id as xid , sum(covunit) as totunits from t1 (where=(rev eq 'N')) group xid) right join t2
on xid eq id;
quit;
