Loop through select and create cursor

Question

Is it possible to create a cursor after looping through a select?
      FOR TEST IN
        SELECT *
          FROM SOMETABLE
         WHERE SOMEID > 100
       ) LOOP
          IF TEST.NAME = 'AB' THEN
               --CREATE CURSOR AND LOAD DATA
               --LOAD TEST.ID, TEST.NAME, TEST.ADATE INTO NEW CURSOR
          END IF;
       END LOOP;     This is just a sample not the actual scenario.

A cursor loop within another cursor loop is known as a nested loop join in SQL. The SQL language is perfectly able to do joins like that. And far better and faster. It has a very clever optimiser and has more sophisticated algorithms than just a nested loop, for joining data sets.
The sample code you've posted shows a very old 80's style Cobol approach to processing ISAM files or magnetic tape. In a row-by-row fashion.
This approach does not scale in the modern database, where the SQL language is a data set processing language - and not an I/O interface for merely reading a record/row and writing a record/row as we did in the 80's with file-based data records.
The basic approach to Oracle is: Maximise SQL. Minimise PL/SQL (Java/etc).
This means using the very flexible, incredibly powerful, SQL language first and foremost to crunch database data. And only when the processing is beyond the capability of the SQL language alone, employ PL/SQL. Else restrict PL/SQL to managing only the process flow and error handling of SQL language statements.
