NEW QUESTION 31
Examine these statements from a block of code:

Which two are true? (Choose two.)

The lock acquired when executing the OPEN c1 command will be released only after a COMMIT or ROLLBACK statement is issued.

Only the PRICE column can be updated in the PRODUCTS table.

The FOR UPDATE OF clause can be used only if the WHERE CURRENT OF clause is used in the executable part of the block.

The WHERE CURRENT OF clause can be used only if the FOR UPDATE clause is used in the cursor definition.

An OPEN c1 command will acquire a lock only on the PRICE column in the PRODUCTS table.

NEW QUESTION 32
Examine these statements which execute successfully:

Which anonymous block executes successfully?

NEW QUESTION 33
Which three are true about the NOCOPY hint, the PARALLEL ENABLE hint, and the DETERMINISTIC clause? (Choose three.)

The PARALLEL_ENABLE clause can be used only in the CREATE FUNCTION statement.

The NOCOPY hint asks the compiler to pass the actual parameters by reference.

A deterministic function’s results always depend on the state of session variables.

The NOCOPY hint asks the compiler to pass the actual parameters by value.

A function is deterministic if it always returns the same result for a specific combination of input values.

The PARALLEL_ENABLE clause can be specified for a nested function.

A function defined with the PARALLEL_ENABLE clause may be executed in parallel in a SELECT statement or a subquery in a DML statement.

NEW QUESTION 34
Which two are true about exception handling? (Choose two.)

Internally defined exceptions can be handled only by the OTHERS exception handler.

All declared exceptions are raised implicitly by the runtime system.

User-defined exceptions can be defined in the declarative part of any PL/SQL anonymous block, subprogram, or package.

Only predefined exceptions and user-defined exceptions can have a user-declared name associated with them.

Predefined exceptions are globally declared in the standard package.

NEW QUESTION 35
Which three are true about functions and procedures? (Choose three.)

The ACCESSIBLE BY clause can be used only for procedures.

In a function, every execution path must lead to a RETURN statement.

Both can have only constants as actual parameters for IN mode parameters.

Both can be invoked from within SQL statements.

In a procedure the RETURN statement cannot specify an expression.

In a function every RETURN statement must specify an expression.

NEW QUESTION 36
Examine this code:
ALTER SESSION SET plsql_warnings=’ENABLE:ALL’;
/
You compile this function:

What happens when the function is created with PLSQL_WARNINGS set to ‘ENABLE: ALL’?

It fails compilation.

There are no compilation warnings or errors.

A severe compilation warning is generated.

A performance compilation warning is generated.

An information compilation warning is generated.

NEW QUESTION 37
User ORA41 executes these statements successfully:
Now, examine this statement which is executed successfully by user ORA61 after a successful login:
EXECUTE ora41.update_emp_proc(100,25000);
Which two are true? (Choose two.)

The salary will be changed for employee 100 in the EMPLOYEES table owned by ORA41.

No update happens even though the procedure executes successfully.

The salary will be changed for employee 100 in the EMPLOYEES table owned by ORA61.

The UPDATE privilege on ORA41.EMPLOYEES is not inherited by ORA61 through the procedure.

ORA61 will have been granted the UPDATE privilege explicitly on ORA41.EMPLOYEES before executing the statement.

NEW QUESTION 38
Which three are true regarding code based access control (CBAC)? (Choose three.)

In a multitenant environment, the DELEGATE option of CBAC cannot be used.

CBAC roles can be granted to a program unit only if they are directly granted to its owner.

CBAC roles can be granted to a program unit only if they are the predefined roles automatically defined by the standard scripts as part of database creation.

You can use CBAC to attach database roles to a PL/SQL function or procedure only.

In CBAC, the ADMIN and DELEGATE options cannot both be granted to the same user.

You can use CBAC to attach database roles to a PL/SQL function, procedure, or package.

CBAC cannot be used to secure definer’s rights.

NEW QUESTION 39
Examine these facts:
Table EMP exists in schema USERA with columns SALARY and EMP_ID.
EMP_ID is the primary key with values ranging from 1 to 100.
USERA now executes these statements successfully:

USERA then grants execute privilege on procedure MYPROC to USERB.
USERB exists in the database identified by pdb1 but does not have select privilege on USERA.EMP.
USERB now executes these statements:
conn userB/userB@pdb1
execute userA.myproc;
Which is true?

It results in an error because Authid Current_User is missing from MYPROC.

It results in an error because Authid Definer is missing from MYPROC.

It results in an error because USERB doesn’t have select privilege on USERA.EMP.

It executes successfully.

NEW QUESTION 40
Which two are valid MODIFIER values for the PLSQL_WARNINGS parameter? (Choose two.)

It might return a run time error depending on who invokes it.

It will always automatically initialize v_raise.

It will set all salaries to NULL if it executes successfully.
