Problem Note 48130: Incorrect results might be generated when you summarize a column in a database management system table
Running an SQL procedure (PROC) query against an Oracle database management system (DBMS) table might result in incorrect results if the query includes an inline view and a summary function both inside and outside of the inline view. The query that is passed to Oracle might not include the GROUP BY clause that was outside the inline view. Also, the summary function that was in the inline view might be recalculated outside the inline view, replacing the calculation from within the inline view.
The problem occurs if you submit a query similar to the following:
proc sql;
select cnts, count(*)
from ( select age, sex, count(*) as cnts
from oralib.class
group by age, sex)
group by cnts;
quit;
What gets submitted to Oracle might be similar to the following:
select COUNT(*) as cnts, COUNT(*) from ( select class."AGE", class."SEX",
COUNT(*) as cnts from CLASS group by CLASS."AGE", CLASS."SEX" )
The only workaround is to break up the query into two queries, such that the first query is the code within the inline view and the second includes the rest of the query, using the output from the first query as input.
