Oracle Database SQL Sample Questions (Q53-Q58):

NEW QUESTION # 53
You have the privileges to create any type of synonym.
Which stalement will create a synonym called EMP for the HCM.EMPLOYEE_RECORDS table that is accesible to all users?

  • A. CREATE GLOBAL SYNONYM emp FOR hcm.employee_records;
  • B. CREATE SYNONYM emp FOR hcm.employee_records;
  • C. CREATE PUBLIC SYNONYM emp FOR hcm. employee_records;
  • D. CREATE SYNONYM SYS.emp FOR hcm.employee_records;
  • E. CREATE SYNONYM PUBLIC.emp FOR hcm.employee_records;

Answer: C

Explanation:
Synonyms in Oracle are aliases for database objects that can simplify SQL statements for database users.
A . The term "GLOBAL" is not used in the creation of synonyms in Oracle.
B . The statement without the keyword PUBLIC will create a private synonym that is only accessible to the user creating the synonym, not all users.
C . The correct syntax does not include PUBLIC as a prefix to the synonym name itself, making this option incorrect.
D . You cannot specify the SYS schema for creating synonyms, as it is reserved for system objects.
E . This is the correct syntax to create a public synonym, which makes the underlying object accessible to all users.
Reference:
Oracle Database SQL Language Reference, 12c Release 1 (12.1): "CREATE SYNONYM"
