질문 # 310
Which three statements are true about inner and outer joins?

A. A left or right outer join returns only unmatched rows.
B. An inner join returns matched rows.
C. A full outer join must use Oracle syntax.
D. A full outer join returns matched and unmatched rows.
E. Outer joins can be used when there are multiple join conditions on two tables.
F. Outer joins can only be used between two tables per query.

정답：B,D

설명：
A: True. A full outer join does indeed return both matched and unmatched rows from both tables involved in the join. It combines the results of both left and right outer joins.
E: True. An inner join, by definition, returns rows that have matching values in both tables. Rows from both tables that do not match are not returned in an inner join result set.
Inner joins match rows from the joined tables based on the join condition, while outer joins include all rows from one or both tables regardless of whether a matching row exists in the other table.
References:The Oracle SQL documentation explains different types of joins, including inner joins, left and right outer joins, and full outer joins, clarifying how they differ in the result sets they produce.
