B. because the lexicon variable is not visible in procedure ADD_ENTRY
C. because the lexicon variable is not initialized in procedure wording
D. because the WORD_LIST parameter in out mode cannot be of a record data type

Q14. /temp/my_files is an existing folder in the server, facultylist.txt is an existing text file in this folder
Examine the following commands that are executed by the DBA:
SQL>CREATE DIRECTION my_dir AS ‘ /temp/my_files’:
SQL>GRANT READ ON DIRECTORY my_dir To pubiic:
View the Exhibit and examine the procedure created by user SCOTT to read the list of faculty names from the text file.

D. The variable x must be declared in the package body and removed from the specification,
Q19. View Exhibit1 and examine the structure of the EMP table.
View Exhibit2 and examine the code created by the user SCOTT:
SCOTT grants the necessary privileges to green to access the EMP table and execute the package.
Examine the following sequence of activities:

SCOTT then issues the SQL>EXEC CURS_PKG.NEXT command.
green starts a session while SCOTT’s session is running and issues THE SQL>EXEC
SCOTT issues the SQI>>EXEC SCOTT.CURS_PKG.NEXT command.
The EMP table contains sequential EMPNOS from 100 through 108.
Which statement correctly describes the output?
A. SCOTT’s session shows the EMPNO 100, GREEN'S session shows an error, and SCOTT’s session shows an error.
B. SCOTT’s session shows the EMPNO 100, GREEN'S session shows EMPNO 100, and SCOTT’s session shows the EMPNO 101.
