--*--
-***-
*****
-***-
--*--
Answer

The output based on the value of 'n'
declare n number(2) default 20;
i number(2);
j number(2);
h number(2);
s number(2);
b varchar2(1) default 'I';
begin
s := 1;
if n mod 2 = 0 then
n := n+1;
end if;
h := n/2 -1;
for i in 1..n loop
for j in 1..h loop
dbms_output.put('-');
end loop;
for j in 1..s loop
dbms_output.put('*');
end loop;
for j in 1..h loop
dbms_output.put('-');
end loop;
dbms_output.put_line(' ');
if n = s then
b := 'D';
end if;
IF b='I' then
s := s+2;
h := h-1;
else
s := s-2;
h := h+1;
end if;
end loop;
end;

Question 8: Aggregate Functions

Examine the description of the STUDENTS table: STD_ID NUMBER(4) COURSE_ID VARCHARD2(10) START_DATE DATE END_DATE DATE Which two aggregate functions are valid on the START_DATE column? (Choose two) A. SUM(start_date) B. AVG(start_date) C. COUNT(start_date) D. AVG(start_date, end_date) E. MIN(start_date) F. MAXIMUM(start_date) Answer: C & E Explanation: It is possible to apply COUNT() and MIN() functions on the column with DATE data type. Incorrect Answers A: Function SUM() cannot be used with DATE data type column. B: Function AVG() cannot be used with DATE data type column. D: Function AVG() cannot be used with DATE data type column, and function AVG() just has one parameter X, not two. It averages all X column values returned by the SELECT statement. F: There is no MAXIMUM() function in Oracle, only MAX() function exists.

The INSERT statement should fail if the user supplies a value other than20 or 50. Which INSERT statement meets the above requirements? A.

19. Oracle Processes

Processes Oracle uses many small (focused) processes to manage and control the Oracle instance. This allows for optimum execution on multi-processor systems using multi-core and multi-threaded technology. Some of these processes include: PMON - Process Monitor SMON - System Monitor ARCn - Redo Log Archiver LGWR - Redo Log Writer DBWn - Database Writer CKPT - Checkpoint process RECO - Recoverer CJQn - Job Queue Coordinator QMNn - Queue-monitor processes Dnnn - Dispatcher Processes (multiplex server-processes on behalf of users) Snnn - Shared server processes (serve client-requests) MMAN - Internal process (used for internal database tasks) LSP0 - Logical standby coordinator process (controls Data Guard log-application) MRP - Media-recovery process (detached recovery-server process) MMON - Memory-monitor process MMNL - Memory monitor light (gathers and stores AWR statistics) PSP0 - Process-spawner (spawns Oracle processes) RFS - Remote file server process (archive to a remote site) DBRM ...
