How to read the output of a command line by line and pass it as a variable?

Hi,

I have some 2000 names in a table like below.
Code:
Java
Oracle/SQL
ANSI SQL
SQL,DWH,DB
DB&Java

And by using for loop in my code i am able to get a single word but if there is any special character or space then it is considering as a next line.

I have to execute the below queries in looping.

Code:
course=select course from table group by 1 order by 1;

Code:
create table table2 as
select * from table where course=$course;
Query3
Query4...

Above set of queries used to execute with different course each time.

I tried using while loop with no luck and unsure what exactly is missing in my code.

Thanks.
