Problem Note 57042: An ORDER BY clause in a PROC SQL statement is ignored in rare cases
 |  |  |  |  |
In rare cases when you select and group aggregate functions in an SQL procedure, the result set is not ordered as expected.
The following example demonstrates the problem:
PROC SQL;
CREATE TABLE result as
SELECT
MIN(table0.age) ,
table0.sex ,
SUM(table0.height) ,
table0.name
FROM
sashelp.class table0
GROUP BY
PUT(table0.age,? 4.),
2,
4
ORDER BY
table0.name ASC ;
QUIT;
After this code is run, the result table is not sorted by the NAME column as instructed.
To obtain the desired sort order, perform a SORT procedure after you run PROC SQL.
