Rows of Data cannot be inserted (Loop Problem) (urgent)

Question

Hi Guys
create table JobWorker
(JobID               Integer,
JobName          char(20),     
Name               char(20),      
Department          char(20),
Responsibilities char(30),
JobRating char(20),
Primary Key (JobID));
Above is my table that requires rows of data.
Create sequence demoseq increment by 1 start with 1;
DECLARE
v_rows integer := 1000; -- THIS IS THE KEY VALUE = NUMBER OF ROWS IN TABLE
v_JobName char(20);
v_temp integer := 1;
BEGIN
FOR v_counter IN 1 .. v_rows LOOP
IF (v_temp > 10) THEN
v_temp := 1;
END IF;
IF (v_temp = 1) THEN
v_JobName := 'Pharmacist';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Richard Smith','Medical', 'Import and Export', 7);
ELSIF (v_temp = 2) THEN
v_JobName := 'Security Officer';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Matt Stevens', 'Security', 'Check Club Tickets', 6);
ELSIF(v_temp = 3) THEN
v_JobName := 'Systems Analyst';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Navdeep Kamboz', 'Finance', 'Analyse Systems', 10);
ELSIF(v_temp = 4) THEN
v_JobName := 'Mathematician';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Paul Potts', 'Algebra and Data Handling', 'Teach Algebra', 4);
ELSIF(v_temp = 5) THEN
v_JobName := 'DB Administrator';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Christine Bleakley', 'Oracle, SQL, DB2', 'Granting User Privileges', 9);
ELSIF(v_temp = 6) THEN
v_JobName := 'Dentist';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Edward Walker', 'Manager', 'General Checkups', 8);
ELSIF(v_temp = 7) THEN
v_JobName := 'Electrician';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Dave Panesar', 'Engineering', 'Examine Specifications', 3);
ELSIF(v_temp = 8) THEN
v_JobName := 'Cricketer';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Sachin Tendulkar', 'Batsman', 'Scoring Hundreds', 9);
ELSIF(v_temp = 9) THEN
v_JobName := 'Personal Trainer';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Brock Lesnar', 'Weights Dept', 'Train People on Weights', 5);
ELSIF(v_temp = 10) THEN
v_JobName := 'Area Manager';
insert into JobWorker values (demoseq.nextval, v_JobName, 'Joe Hoffland', 'Midlands', 'Visit Stores and Examine', 2);
END IF;
END LOOP;
END;
It does work...but the following problems I get are...
As you can see I have populated the tables as a Loop..
But if I was to generate a statement : Select * from JobWorker WHERE Name = 'Joe Hoffland';
It provides me with the result as 'No Rows Selected'.
The first Insert consists of someone called Richard Smith. Every row of data is only populated with his name and his row of data.
I cannot get the other 9 insert rows to work....
Is there something wrong with the above code? I require your help guys! Thank You!

Incrementing v_temp would help :). Also column department length is too small. You need to increase it to 25. And sing CHAR isn't a good idea. Use VARCHAR2 instead:
