NEW QUESTION # 301
Which two are true about creating tables in an Oracle database?

A. A create table statement can specify the maximum number of rows the table will contain.
B. A primary key constraint is manadatory.
C. The same table name can be used for tables in different schemas.
D. Creating an external table will automatically create a file using the specified directory and file name.
E. A system privilege is required.

Answer: A,C

NEW QUESTION # 302
Examine the description of the BOOKS table:

The table has 100 rows.
Examine this sequence of statements issued in a new session;
INSERT INTO BOOKS VALUES ('ADV112' , 'Adventures of Tom Sawyer', NULL, NULL); SAVEPOINT a; DELETE from books; ROLLBACK TO SAVEPOINT a; ROLLBACK; Which two statements are true?

A. The second ROLLBACK command replays the delete.
B. The second ROLLBACK command does nothing.
C. The second ROLLBACK command undoes the insert.
D. The first ROLLBACK command restores the 101 rows that were deleted and commits the inserted row.
E. The first ROLLBACK command restores the 101 rows that were deleted, leaving the inserted row still to be committed.

Answer: B,C

Explanation:
B: True. The second ROLLBACK command would not do anything because the first ROLLBACK TO SAVEPOINT a; already undid the delete operation, and there was no other DML operation between the first and the second ROLLBACK.
E: True. The second ROLLBACK command undoes the insert because after the first ROLLBACK TO SAVEPOINT a; there are no savepoints defined, so a subsequent ROLLBACK would undo all transactions to the beginning of the current session or last COMMIT.
The ROLLBACK command is used to undo transactions that have not yet been committed. Rolling back to a savepoint only undoes transactions up to that savepoint, and a subsequent ROLLBACK without a savepoint name will undo all uncommitted changes since the last COMMIT.
Reference:
Oracle SQL documentation on the ROLLBACK statement provides details on how it interacts with savepoints and the effects it has on the transactions within a session.

NEW QUESTION # 303
Evaluate the following statement.

Which statement is true regarding the evaluation of rows returned by the subquery in the INSERT statement?

A. They are evaluated by all the three WHEN clauses regardless of the results of the evaluation of any other WHEN clause.
B. The insert statement would give an error because the ELSE clause is not present for support in case none of WHEN clauses are true.
C. They are evaluated by the first WHEN clause. If the condition is false, then the row would be evaluated by the subsequent WHEN clauses.
D. They are evaluated by the first WHEN clause. If the condition is true, then the row would be evaluated by the subsequent WHEN clauses.

Answer: A

NEW QUESTION # 304
The INVOICE table has a QTY_SOLD column of data type NUMBER and an INVOICE_DATE column of data type DATE NLS_DATE_FORMAT is set to DD-MON-RR.
Which two are true about data type conversions involving these columns in query expressions?

A. CONCAT(qty_sold, invoice_date): requires explicit conversion
B. invoice_date = '15-march-2019': uses implicit conversion
C. qty_sold ='05549821 ': requires explicit conversion
D. qty_sold BETWEEN '101' AND '110': uses implicit conversion
E. invoice_date> '01-02-2019': uses implicit conversion

Answer: B,E

Explanation:
The statements regarding data type conversions and the treatment of literals in SQL expressions involve understanding implicit and explicit data conversions in Oracle SQL.
Statement A is true as invoice_date > '01-02-2019' involves an implicit conversion of the string literal to a date type, based on the NLS_DATE_FORMAT setting, assuming the format matches.
Statement E is true because, similarly to A, invoice_date = '15-march-2019' involves an implicit conversion where the string is automatically converted to a date type according to the Oracle NLS_DATE_FORMAT or an assumed default date format.
Statements B, C, and D involve incorrect or misleading information:
B (qty_sold = '05549821') is misleading and potentially incorrect as leading zeros in a numeric context do not typically require explicit conversion but the presence of spaces might suggest a need for trimming rather than numeric conversion.
C (CONCAT(qty_sold, invoice_date)) would indeed require explicit conversion because CONCAT expects string types, and thus numerical and date values must be explicitly converted to strings before concatenation.
D (qty_sold BETWEEN '101' AND '110') uses implicit conversion where the string literals '101' and '110' are implicitly converted to numbers if qty_sold is a numeric type.
