You must have completed 60 undergraduate credits in Computer Science, Information Systems Management, Information Tech, or related discipline.

The fundamental tenet of Oracle Database Administration is that before you can administer a database, you must know how to create one. This chapter covers the creation of database objects in general and goes into detail on creating tables, views managing, indexes, sequences, and triggers. It also discusses how to use PL/SQL code inside SQL statements to create object definitions or assignments without having to resort to interactively coding them inside SQL*Plus or through direct DDL statements with CREATE statements.

Oracle Database SQL Sample Questions (Q12-Q17):

NEW QUESTION # 12
You want to write a query that prompts for two column names and the WHERE condition each time It is executed in a session but only prompts for the table name the first time it is executed. The variables used in your query are never undefined in your session . Which query can be used?

A. SELECT &col1, &col2
FROM &&table
WHERE &condition;
B. SELECT&&col1, &&col2
FROM &table
WHERE &&condition;
C. SELECT'&co11','&&co12'
FROM &table
WHERE'&&condition' ='&cond';
D. SELECT &&col1,&&col2
FROM &table
WHERE &&condition= &&cond;
E. SELECT &col1, &col2
FROM "&table"
WHERE &condition;

Answer: A

Explanation:
The scenario requires prompting for column names and WHERE condition each time the query is executed, but only prompting for the table name once. This behavior is achievable through the use of substitution variables in SQL*Plus or SQL Developer:
* A.
SELECT &col1, &col2 FROM &&table WHERE &condition;
This query uses & for columns and condition, which will prompt every time the query is run. &&table will prompt for the table name the first time and reuse the same value in the same session without re-prompting.
Options B, C, D, and E use incorrect syntax or variable types, leading to various errors or undesired behaviors, such as not maintaining the value of the table name across executions or incorrect usage of single quotes and comparison in SQL.
