NEW QUESTION # 171
Which two statements are true about substitution variables?

  • A. A substitution variable can be used only in a SELECT statement.
  • B. A substitution variable used to prompt for a column name must be endorsed in single quotation marks.
  • C. A substitution variable prefixed with & always prompts only once for a value in a session.
  • D. A substitution variable can be used with any clause in a SELECT statement.
  • E. A substitution variable prefixed with 6 prompts only once for a value in a session unless is set to undefined in the session.
  • F. A substitution variable used to prompt for a column name must be endorsed in double quotation marks.

Answer: C,D

Explanation:
Substitution variables in Oracle are used to replace a value dynamically during the execution of SQL statements. The behavior of these variables is well-documented:
C . A substitution variable prefixed with & always prompts only once for a value in a session: This is true. In a session, when you use a single ampersand (&), SQL*Plus or SQL Developer will prompt for the value the first time the variable is encountered. The value for this variable will then be reused for the remainder of the session unless it is redefined.
D . A substitution variable can be used with any clause in a SELECT statement: Substitution variables can be placed in any part of a SQL statement, including the SELECT, WHERE, GROUP BY, ORDER BY, etc. They are not limited to any specific clause.
Reference:
Oracle SQL*Plus User's Guide and Reference, which discusses substitution variables.
