Oracle Database SQL Sample Questions (Q146-Q151):

NEW QUESTION # 146
Which two statements are true about sequences created in a single instance database? (Choose two.)

A. The numbers generated by a sequence can be used only for one table
B. When the MAXVALUE limit for a sequence is reached, you can increase the MAXVALUE limit by using the ALTER SEQUENCE statement
C. DELETE <sequencename> would remove a sequence from the database
D. CURRVAL is used to refer to the last sequence number that has been generated
E. When a database instance shuts down abnormally, the sequence numbers that have been cached but not used would be available once again when the database instance is restarted

Answer: B,D

Explanation:
Gaps in the Sequence
Although sequence generators issue sequential numbers without gaps, this action occurs
independent of a commit or rollback. Therefore, if you roll back a statement containing a
sequence, the number is lost.
Another event that can cause gaps in the sequence is a system crash. If the sequence
caches values in memory, those values are lost if the system crashes.
Because sequences are not tied directly to tables, the same sequence can be used for
multiple tables.
However, if you do so, each table can contain gaps in the sequential numbers.
Modifying a Sequence
If you reach the MAXVALUE limit for your sequence, no additional values from the sequence are allocated and you will receive an error indicating that the sequence exceeds the MAXVALUE. To continue to use the sequence, you can modify it by using the ALTER SEQUENCE statement To remove a sequence, use the DROP statement:
DROP SEQUENCE dept_deptid_seq;

NEW QUESTION # 149
Whith three statements are true about built in data types?

A. A CHAR column definition does not require the length to be specified
B. The default length for a CHAR column is always one character
C. A VARCHAR2 blank pads column values only if the data stored is non numeric and contains no special characlers
D. A BLOB stores unstructured binary data within the database
E. A BFILE stores unstructured binary data in operating systerm files
F. A VARCHAR2 column definition does not require the length to be specified

Answer: B,D,E

Explanation:
The true statements about built-in data types in Oracle are:
B: A BFILE is a data type in Oracle that allows for a read-only link to binary files stored outside the database in the operating system. This is correct as per Oracle's documentation.
D: The default length for a CHAR column, when not specified, is one character. This is according to the Oracle SQL standard.
F: A BLOB is used for storing binary data within the Oracle database, allowing for storage of large amounts of unstructured binary data.
The incorrect options are:
A: A VARCHAR2 column does not blank-pad values; it is CHAR that may blank-pad to the fixed length.
C: A CHAR column requires a length specification, although if omitted, the default is one character.
E: A VARCHAR2 column requires a length specification; without it, the statement will fail.
