NO.3 Examine the structure proposed for the transactions table:

Which two statements are true regarding the creation and storage of data in the above table

structure?

A. The CUST_STATUS column would give an error.

B. The TRANS_VALIDITY column would give an error.

C. The CUST_STATUS column would store exactly one character.

D. The CUST_CREDIT_LIMIT column would not be able to store decimal values.

E. The TRANS_VALIDITY column would have a maximum size of one character.

F. The TRANS_DATE column would be able to store day, month, century, year, hour, minutes,

seconds, and fractions of seconds

Answer: B,C

Explanation:

VARCHAR2(size)Variable-length character data (A maximum size must be specified:

minimum size is 1; maximum size is 4, 000.)

CHAR [(size)] Fixed-length character data of length size bytes (Default and minimum size

is 1; maximum size is 2, 000.)

NUMBER [(p, s)] Number having precision p and scale s (Precision is the total number of

decimal digits and scale is the number of digits to the right of the decimal point; precision

can range from 1 to 38, and scale can range from -84 to 127.)

DATE Date and time values to the nearest second between January 1, 4712 B.C., and

December 31, 9999 A.D.

NO.4 Evaluate the following SQL statement:

Which statement is true regarding the outcome of the above query?

A. It executes successfully and displays rows in the descending order of PROMO_CATEGORY .

B. It produces an error because positional notation cannot be used in the order by clause with set

operators.

C. It executes successfully but ignores the order by clause because it is not located at the end of the

compound statement.

D. It produces an error because the order by clause should appear only at the end of a compound

query-that is, with the last select statement.

NO.5 You need to create a table for a banking application. One of the columns in the table has the

following requirements:

1. You want a column in the table to store the duration of the credit period.

2) The data in the column should be stored in a format such that it can be easily added and

subtracted with date data type without using conversion functions.

3) The maximum period of the credit provision in the application is 30 days.

4) The interest has to be calculated for the number of days an individual has taken a credit for.

Which data type would you use for such a column in the table?

A. DATE

B. NUMBER

C. TIMESTAMP

D. INTERVAL DAY TO SECOND

E. INTERVAL YEAR TO MONTH

Answer: D

NO.6 View the Exhibit and evaluate the structure and data in the CUST_STATUS table.

You issue the following SQL statement:

Which statement is true regarding the execution of the above query?

A. It produces an error because the AMT_SPENT column contains a null value.

B. It displays a bonus of 1000 for all customers whose AMT_SPENT is less than CREDIT_LIMIT.

C. It displays a bonus of 1000 for all customers whose AMT_SPENT equals CREDIT_LIMIT, or

AMT_SPENT is null.

D. It produces an error because the TO_NUMBER function must be used to convert the result of the

NULLIF function before it can be used by the NVL2 function.

Answer: C

Explanation:

The NULLIF Function The NULLIF function tests two terms for equality. If they are equal the function

returns a null, else it returns the first of the two terms tested. The NULLIF function takes two

mandatory parameters of any data type. The syntax is NULLIF(ifunequal, comparison_term), where

the parameters ifunequal and comparison_term are compared. If they are identical, then NULL is

returned. If they differ, the ifunequal parameter is returned.

PDTNO in product table and COMPNO is the foreign key referencing the COMPNO in component

table.

You want to generate a report listing the product names and their corresponding component names,

if the component names and product names exist.

Evaluate the following query:

SQL>SELECT pdtno, pdtname, compno, compname
