Oracle Database SQL 1z1-071 Prüfungsfragen mit Lösungen (Q44-Q49):

44. Frage
Which two are true about rollbacks?

A. Data consistency is not guaranteed after a rollback.
B. The ROLLBACK statement does not release locks resulting from table updates.
C. A transaction interrupted by a system failure is automatically rolled back.
D. Data Control L anguage (DCL) statements, such as GRANT and REVOKE, can be rolled back.
E. If the ROLLBACK statement is used without TO SAVEPOINT, then all savepoints in the transaction are deleted .

Antwort: C,E

Begründung:
C). True. A transaction that is interrupted by a system failure is automatically rolled back by Oracle to ensure data consistency. This is part of the ACID (Atomicity, Consistency, Isolation, Durability) properties that Oracle adheres to.
D). True. A ROLLBACK without specifying a savepoint rolls back the entire transaction and removes all savepoints within that transaction. This restores the data to the state it was in at the beginning of the transaction.

45. Frage
SELECT *
FROM bricks,colors;
Which two statements are true?

A. It returns the number of rows in BRICKS plus the number of rows in COLORS.
B. You can add an ON clause with a join condition.
C. It returnsthe same rows as SELECT * FROM bricks CROSS JOIN colors.
D. You can add a USING clause with a join condition.
E. You can add a WHERE clause with filtering criteria.

Antwort: C,E

46. Frage
View the Exhibit and examine the structure of ORDERS and ORDER_ITEMS tables.
ORDER_ID is the primary key in the ORDERS table and the foreign key of the ORDER_ITEMS table, whose constraint is defined with the ON DELETE CASCADE option.
Which DELETE statement would execute successfully?

A. DELETE orders o, order_items iWHERE o.order_id = i.order_id;
B. DELETE order_idFROM ordersWHERE order_total < 1000;
C. DELETE ordersWHERE order_total < 1000;
D. DELETEFROM ordersWHERE (SELECT order_idFROM order_items);

Antwort: C

47. Frage
Choose two
Examine the description of the PRODUCT DETALS table:

A. PRODUCT_ID can be assigned the PEIMARY KEY constraint.
B. EXPIRY_DATE contains the SYSDATE by default if no date is assigned to it
C. EXPIRY_DATE cannot be used in arithmetic expressions.
D. PRODUCT_PRICE contains the value zero by default if no value is assigned to it.
E. PRODUCT_PRICE can be used in an arithmetic expression even if it has no value stored in it
F. PRODUCT_NAME cannot contain duplicate values.

Antwort: A,E

48. Frage
Which three are true about the CREATE TABLE command?

A. It implicitly rolls back any pending transactions.
B. It can include the CREATE...INDEX statement for creating an index to enforce the primary key constraint.
C. The owner of the table must have the UNLIMITED TABLESPACE system privilege.
D. The owner of the table should have space quota available on the tablespace where the table is defined.
E. A user must have the CREATE ANY TABLE privilege to create tables.
F. It implicitly executes a commit.

Antwort: D,E,F

Begründung:
A). False - The CREATE TABLE command cannot include a CREATE INDEX statement within it. Indexes to enforce constraints like primary keys are generally created automatically when the constraint is defined, or they must be created separately using the CREATE INDEX command.
B). True - The owner of the table needs to have enough space quota on the tablespace where the table is going to be created, unless they have the UNLIMITED TABLESPACE privilege. This ensures that the database can allocate the necessary space for the table. Reference: Oracle Database SQL Language Reference, 12c Release 1 (12.1).
C). True - The CREATE TABLE command implicitly commits the current transaction before it executes. This behavior ensures that table creation does not interfere with transactional consistency. Reference: Oracle Database SQL Language Reference, 12c Release 1 (12.1).
D). False - It does not implicitly roll back any pending transactions; rather, it commits them.
E). True - A user must have the CREATE ANY TABLE privilege to create tables in any schema other than their own. To create tables in their own schema, they need the CREATE TABLE privilege. Reference: Oracle Database Security Guide, 12c Release 1 (12.1).
F). False - While the UNLIMITED TABLESPACE privilege allows storing data without quota restrictions on any tablespace, it is not a mandatory requirement for a table owner. Owners can create tables as long as they have sufficient quotas on the specific tablespaces.
