Oracle Database SQL Sample Questions (Q426-Q431):

NEW QUESTION # 426
Which two are true about global temporary tables?

A. If the ON COMMIT clause is session-specific,the table is dropped when the session is terminated.
B. They can be created only by a user with the DBA role,but can be accessed by all users who can create a session.
C. Indexes can be created on them.
D. If the ON COMMIT clause Is transaction-specific, all rows in the table are deleted alter each COMMIT or ROLLBACK.
E. Their data is always stored in the default temporary tablespace of the user who created them.
F. Backup and recovery operations are available for these tables.

Answer: C,D

Explanation:
E). True. Indexes can be created on global temporary tables just like they can on permanent tables. The indexes on global temporary tables are also temporary and only exist for the duration of the session or transaction, based on how the table was defined.
F). True. If the ON COMMIT clause is specified as DELETE ROWS, then all rows in the global temporary table are deleted after each COMMIT or ROLLBACK within the transaction. This clause defines the scope of the data's persistence within the global temporary table.

NEW QUESTION # 427
Which three statements are true about indexes and their administration in an Oracle database?

A. A DROP INDEX statement always prevents updates to the table during the drop operation
B. A descending index is a type of function-based index
C. An INVISIBLE index is not maintained when Data Manipulation Language (DML) is performed on its underlying table.
D. A UNIQUE and non-unique index can be created on the same table column
E. If a query filters on an indexed column then it will always be used during execution of the query
F. An index can be created as part of a CREATE TABLE statement.

Answer: B,D,F

Explanation:
A). This statement is incorrect. An INVISIBLE index is maintained during DML operations just like a VISIBLE index. The difference is that an INVISIBLE index is not used by the optimizer unless explicitly hinted. B. This statement is correct. When creating a table, you can define indexes on one or more columns as part of the table definition. C. This statement is incorrect. While a DROP INDEX statement will drop the index, it does not always prevent updates to the table. If the index is marked as unusable or is an invisible index, for example, updates can still be performed. D. This statement is correct. It is possible to have both a UNIQUE index and a non-unique index on the same column. The UNIQUE index enforces the uniqueness of column values, while the non-unique index does not. E. This statement is correct to some extent. Descending indexes are not function-based indexes per se, but they are indexes on which the data is sorted in descending order, as opposed to the default ascending order. However, descending indexes are conceptually related to function-based indexes because they alter the way the indexed data is stored. F. This statement is incorrect.
The use of an index in query execution depends on the optimizer's decision, which is based on statistics and the cost associated with using the index. There are situations where the optimizer may choose a full table scan even if there is an index on the filter column.
References can be found in the Oracle Database Concepts Guide and the SQL Language Reference documentation, which detail the behavior of indexes and how they are managed within the Oracle database.
