oracle - SQL*Plus does not execute SQL scripts that SQL Developer does

Question

I am facing a very annoying problem. I have written (in Notepad++) some SQL scripts. Now when I try to execute them by SQL*Plus (through the command line, on Windows 7), I am getting errors like ORA-00933: SQL command not properly ended.

Then I copy & paste the script into the SQL Developer worksheet window, hit the Run button, and the script executes without any problem/errors.

After a long investigation, I came to think that SQL*Plus has a problem with some whitespaces (including newline characters and tabs) that it does not understand.

Since I assume that SQL Developer knows how to get rid of the weird whitespaces, I have tried this: paste the script into the SQL Developer worksheet window, then copy it from there and paste it back in the SQL script. That solved the problem for some files, but not all the files. Some files keep showing errors in places for no apparent reason.

Have you ever had this problem? What should I do to be able to run these scripts by SQL*Plus through the command line?

UPDATE:

An example of a script that did not work with SQL*Plus but did work with SQL Developer:

SET ECHO ON;

INSERT INTO MYDB.BOOK_TYPE (
    BOOK_TYPE_ID, UNIQUE_NAME, DESCRIPTION, VERSION, IS_ACTIVE, DATE_CREATED, DATE_MODIFIED
)
SELECT MYDB.SEQ_BOOK_TYPE_ID.NEXTVAL, 'Book-Type-' || MYDB.SEQ_BOOK_TYPE_ID.NEXTVAL, 'Description-' || MYDB.SEQ_BOOK_TYPE_ID.NEXTVAL, A.VERSION, B.IS_ACTIVE, SYSDATE, SYSDATE FROM

    (SELECT (LEVEL-1)+0 VERSION FROM DUAL CONNECT BY LEVEL<=10) A,
    (SELECT (LEVEL-1)+0 IS_ACTIVE FROM DUAL CONNECT BY LEVEL<=2) B

;

The error I get:

SQL> SQL> SET ECHO ON;
SQL>
SQL> INSERT INTO MYDB.BOOK_TYPE (
  2      BOOK_TYPE_ID, UNIQUE_NAME, DESCRIPTION, VERSION, IS_ACTIVE, DATE_CREATED, DATE_MODIFIED
  3  )
  4  SELECT MYDB.SEQ_BOOK_TYPE_ID.NEXTVAL, 'Book-Type-' || MYDB.SEQ_BOOK_TYPE_ID.NEXTVAL, 'Description-' || MYDB.SEQ_BOOK_TYPE_ID.NEXTVAL, A.VERSION, B.IS_ACTIVE, SYSDATE, SYSDATE FROM
  5  
SQL>         (SELECT (LEVEL-1)+0 VERSION FROM DUAL CONNECT BY LEVEL<=10) A,
  2          (SELECT (LEVEL-1)+0 IS_ACTIVE FROM DUAL CONNECT BY LEVEL<=2) B
  3  
SQL> ;
  1     (SELECT (LEVEL-1)+0 VERSION FROM DUAL CONNECT BY LEVEL<=10) A,
  2*    (SELECT (LEVEL-1)+0 IS_ACTIVE FROM DUAL CONNECT BY LEVEL<=2) B

As you see the error is on (SELECT (LEVEL-1)+0 IS_ACTIVE FROM DUAL CONNECT BY LEVEL<=2) B (for some reason in all the files that get this error, the error appears on the last line before the concluding semicolon.)

Remove the empty lines.
In sqlplus an empty line means stop previous statement and start a new one.

or you can set blank lines:

set sqlbl on
