Question 64/139

Examine this query:
SELECT employee_id, first_name, salary
FROM employees
WHERE hiredate > 61*
Which two methods should yours to prevent prompting for hire date value when this queries executed?

A. Execute the SET VERIFY ON command before executing the query.

B. Execute the SET VERIFY OFF command before executing the query.

C. Store the query in a script and pass the substitution value to the script when executing it.

D. Replace 's1' with &1'in the query:

E. Use the UNDEFINE command before executing the query.

F. Use the DEFINE command before executing the query

Correct Answer: B,F

To prevent the prompting for a substitution variable value when executing a query:
* B. Execute the SET VERIFY OFF command before executing the query: This command turns off the substitution variable prompting, which means that SQL*Plus will not prompt for a value and will use whatever value is currently set for that variable.
* F. Use the DEFINE command before executing the query: By using the DEFINE command to set a value for the variable before the query execution, you ensure that SQL*Plus uses this predefined value instead of prompting for it.
References:
* Oracle SQL*Plus User's Guide and Reference, which discusses how to manage substitution variables.
