Problem Note 50949: Using the position rather than the name of a variable in a GROUP BY clause might result in an error
An error might occur when you run an SQL procedure query when the following conditions exist:
- An SQL view includes the creation of a new variable as a result of a summary function.
- The view is used in a subsequent query where it is joined to another table using an outer join and the new variable is used in the GROUP BY clause.
- The variable position in the SELECT clause rather than the variable name is used in the GROUP BY clause.
The error might look similar to the following:
ERROR: GROUP BY clause contains a summary function, which is not allowed.
ERROR: Summary functions are restricted to the SELECT and HAVING clauses only.
Submitting a query similar to the following might result in the above error:
proc sql;
create view v2 as
select
x, y, max(z) as mz
from t2
group by x, y;
quit;
proc sql;
create table results as
select t1.x, sum(t1.y) as sy, v2.mz
from t1 left join v2
on t1.x=v2.x
group by 3;
quit;
The only workaround is to use the variable name rather than its position in the GROUP BY clause.
