Oracle Database SQL Sample Questions (Q209-Q214):

NEW QUESTION # 209
Examine this description of the PRODUCTS table:

Rows exist in this table with data in all the columns. You put the PRODUCTS table in read-only mode. Which three commands execute successfully on PRODUCTS?

A. DROP TABLE products
B. TRUNCATE TABLE products;
C. ALTER TABLE products SET UNUSED(expiry_date);
D. ALTER TAELE products DROP COLUMN expiry_date;
E. CREATE INDEX price_idx on products (price);
F. ALTER TABLE products DROP UNUSED COLUMNS

Answer: A,E,F

NEW QUESTION # 210

You execute the following command:

Which two statements are true? (Choose two.)

A. A new column, COUNTRY, can be added to the DEPARTMENTStable after executing the command.
B. Unique key constraints defined on the COUNTRYcolumn are removed.
C. Views created in the DEPARTMENTStable that include the COUNTRYcolumn are automatically modified and remain valid.
D. Synonyms existing of the DEPARTMENTStable would have to be re-created.
E. Indexes created on the COUNTRYcolumn exist until the DROP UNUSED COLUMNScommand is executed.

Answer: A,B

NEW QUESTION # 211
Examine the description of the ENPLOYES table:

Which query requires explicit data type conversion?

A. SELECT join_ date + '20' EROM employees;
B. SELECT SUBSTR(join date, 1, 2) - 10 FROM employees;
C. SELECT salary + '120.50' FROM employees;
D. SELECT join _ date FROM employees WHERE join date > *10-02-2018';
E. SELECT join_ date||''|| salary FROM employees;

Answer: D

Explanation:
A look at the queries and how Oracle Database handles data type conversion:
A: This statement takes a substring of the JOIN_DATE column. Since JOIN_DATE is a DATE type and SUBSTR function expects a string, implicit conversion will occur from DATE to string based on the NLS_DATE_FORMAT setting. However, this will not require explicit conversion in the query itself.
B: This statement tries to add '20' to JOIN_DATE. Oracle Database does not support adding a string to a DATE implicitly. An explicit conversion of '20' to a number is required, or using the INTERVAL keyword to add days or years as appropriate.
C: This statement concatenates the date with an empty string and the salary. The database will implicitly convert the JOIN_DATE from a DATE to a string using the NLS_DATE_FORMAT setting and then perform the concatenation.
D: This query attempts to compare a DATE column with a string literal '*10-02-2018'. An explicit conversion using TO_DATE is needed to convert the string to a DATE data type with the appropriate date format mask. In this case, because the string does not follow the NLS_DATE_FORMAT 'DD-MON-YY', it will not be implicitly converted correctly.
E: This statement adds '120.50' to SALARY. Oracle Database will implicitly convert the string '120.50' to a number before performing the arithmetic addition, as SALARY is a NUMBER data type.

NEW QUESTION # 212
Examine these statements and results:
SQL> SELECT COUNT(*) FROM emp
COUNT(*)
---------------------
14
sQL> CREATE GLOBAL TEMPORARY TABLE t emp As SELECT * FROM emp;
Table created
SQL> INSERT INTo temp SELECT * FROM emp;
14 rows created
SQL> COMMIT:
Commit complete*
SQL> INSERT INTo temp SELECT * EROM emp;
14. rows created
SQL> SELECT COUNT(*) FROM t emp
How many rows are retrieved by the last query?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
Global temporary tables in Oracle Database are designed to hold temporary data for the duration of a session or a transaction.
Given that the global temporary table is created and then populated twice from the emp table without any mention of data deletion, one would initially think the count would be 28, since 14 rows are inserted twice. However, if the temporary table was created with the default ON COMMIT DELETE ROWS option, the rows are deleted at the end of the transaction, which is signified by the COMMIT operation.
Thus, after the first COMMIT, the temporary table would be empty. After the second INSERT, another 14 rows would be added. So, the last query would retrieve 14 rows unless a DELETE operation was committed.
Reference:
Oracle Documentation on Temporary Tables: https://docs.oracle.com/cd/B28359_01/server.111/b28310/tables003.htm#ADMIN11633 Please note that the actual number of rows retrieved by the last query could differ if there are any triggers, cascading deletes, or the table is defined differently than assumed in this context.

NEW QUESTION # 213
Examine this partial command:
CREATE TABLE cust(
cust_id NUMBER(2),
credit_limit NUMBER(10)
ORGANIZATION EXTERNAL
Which two clauses are required for this command to execute successfully?

A. the ACCESS PARAMETERS clause
B. the LOCATION clause
C. the access driver TYPE clause
D. the REJECT LIMIT clause
E. the DEFAULT DIRECTORY clause

Answer: A,B

Explanation:
When creating an external table, which allows you to access data in a flat file as though it is a table inside the database, certain clauses are required:
A . the ACCESS PARAMETERS clause: This clause specifies the parameters required by the access driver to read the data files.
D . the LOCATION clause: This clause specifies the location of the data files that make up the external table.
Reference:
Oracle Database SQL Language Reference 12c, particularly the sections detailing the creation and management of external tables.
