LIMIT clause usage in PLSQL - oracle

Question

I have a procedure which is used for extracting data and then inserting them. My problem is that I am using BULK COLLECTION. My goal is that I want to every time extract for example 10,000 data then insert these 10,000 records. But in my script I can limit it with that value but it doesn't insert more. For instance I have 6 records and I used 4 with LIMIT clause. What I want is the procedure should first insert 4 record then extract remaining 2 records for example.
I have I can describe issue briefly. I am open to any fix advices in my scripts. Thank you from now.
I solved my problem added new version of script below, thank you everyone

You need a LOOP in order to fetch multiple subsets of records. Example snippet:
...
loop
FETCH c1 BULK COLLECT INTO l_prod_ids LIMIT c_limit;
exit when l_prod_ids.count = 0;
FOR indx IN 1 .. l_prod_ids.COUNT
...
end loop;
CLOSE c1;
...
Incidentally, executing thousands of individual INSERT statements is a recipe for poor performance. You should use the FORALL syntax (which is not a loop) to execute a set-based insert operation driving from your collection. Find out more.
You should also give consideration as to whether you ought to be using a collection at all, when you could just use a pure SQL INSERT INTO ... SELECT ... FROM statement. That would perform even better than a FORALL operation.
