SELECT문에서 DISTINCT와 ORDER BY절을 함께 사용할 땐
ORDER BY 절에는 SELECT문에 사용한 ITEM만을 적을 수 있다.
(또는 ORDER BY절에서 ITEM을 삭제)
ORA-01791 not a SELECTed expression
Cause:
There is an incorrect ORDER BY item. The query is a SELECT
DISTINCT query with an ORDER BY clause. In this context, all ORDER BY
items must be constants, SELECT list expressions, or expressions whose
operands are constants or SELECT list expressions.
Action:
Remove the inappropriate ORDER BY item from the SELECT list and
retry the statement.
