How To Use "WHILE" Loop Statements?
If you have a block of codes to be executed repeatedly based a condition,
you can use the "WHILE ... LOOP" statement. Here is a sample script on WHILE statements:

total := total+1;
DBMS_OUTPUT.PUT_LINE('Total counts: ' || TO_CHAR(total));
This script should print this:
Total counts: 10
