If I run this query in sql tools I can see the error is pointing before NOT in where condition ( /*REMAINING_ROWS - NOT EDITABLE*/ (NOT (("SPLITTER_INPUT_SUBQUERY"."LEVEL_FK_KEY" IS NULL )I saw all my comments are terminated properly but still this error is coming.If possible can someone please have a look at it and let me know your comments.
Thanks in advance.

Hi, Amrit,
Whenever you have a problem, post a complete test script that people can run to re-create the problem and test their ideas. Include CREATE TABLE and INSERT statements for all tables needed.
Simplify the problem as much as possible. Don't post 150 lines of code if you can get the same error in 15 lines, or 5. I'll bet this problem can be illustrated with a very short query referencing only dual.
Always say which version of Oracle you're using.
See the forum FAQ {message:id=9360002}

I can see the error is pointing before NOT in where condition ( /*REMAINING_ROWS - NOT EDITABLE*/ (NOT (("SPLITTER_INPUT_SUBQUERY"."LEVEL_FK_KEY" IS NULL )Post the exact error message. Use \ tags to show, as closely as possible, how it indicated that place.  (However, error messages like this often don't really point to where the problem is.)
I saw all my comments are terminated properly but still this error is coming.If possible can someone please have a look at it and let me know your comments.How is this statement being ended?
In SQL*Plus, statements have to be eneded with a semicolon or slash.  Comments are not allowed after that ';' or '/', on the same line.  For example:SELECT     *
FROM     dual
;     /* No comments here */
You can, however, have comments immediately before and/or after that line:SELECT     *
FROM     dual
/* Comments are allowed here */
/* Comments are allowed here, too */
Perhaps your tool is implicitly putting a ';' or '/' somewhere that is not allowed.  Try moving the comment away from the end of the statement.
