即使在PL / SQL中发生异常，也继续循环读取Excel行

Question

Here's the overview of the code:

PROCEDURE

BEGIN
  WHILE LOOP --loop each row
    --Read each row and add in table
    COMMIT;
  END LOOP;
EXCEPTION
  WHEN OTHERS
    --log error
    ROLLBACK;
END;

Ex: There are 5 lines. The 3rd line has an error in it. The program stops right after it reads the error line, making the other lines next to it not evaluated/read. My goal is after it went to the exception, it will output the line and continue with reading the other lines. So how do I return back to the loop if it went to the exception?

Answer 1

Try this, then you will cache error only in inner anonymous block:

PROCEDURE

BEGIN
  WHILE LOOP --loop each row
    BEGIN
      --Read each row and add in table
      COMMIT;
    EXCEPTION
      WHEN OTHERS
        --log error
        ROLLBACK;
    END;
  END LOOP;

END;

Answer 2

Try using a independent PL/SQL block in the loop itself.

BEGIN
      WHILE LOOP --loop each row
        BEGIN
        --Read each row and add in table
        COMMIT;
            EXCEPTION --Catch the exception here and print the data and it will move on
        END;
      END LOOP;
    EXCEPTION
      WHEN OTHERS
        --log error
        ROLLBACK;
    END;
