Executing SQL's in parallel

Hi Folks,

I have requirement to pull a bunch of SQL's from a table in DB and execute them in parallel and update the status of each query as and when they complete. Can you please help me with ideas on how this can be achieved?

Code:
 
create table list_of_sql
(
id number,
full_sql varchar2(255),
status varchar2(50),
create_dt timestamp,
update_dt timestamp
)

id - auto-generated number
full_sql - will have the sql to be executed
status - P : Pending (when the sql is added but not picked up for execution yet)
A : Active (Once the query is picked up for execution and is running)
C : Completed (Once the query execution has completed)

It will be easy to do this sequentially but the requirement is to run the sql's in parallel and at a time there will be no more than 10 sql;s in the table.

Thanks in advance.
