Problem Oracle with \ and and

Hello for all, I'm a new user and my English isn't very good .. sorry!
I have a problem with an INSERT in Oracle, the code tha I inserd is:

INSERT INTO Schema VALUES(schema_seq.nextval,C:\Documents and Settings\Laura\Desktop\Tesi\File_OGaggi)

the error is:

Error: ORA-00911: invalid character

[Executed: 13/11/03 10.31.25 GMT ] [Execution: 0/ms]

I think that the problems are '\' and the word 'and'. Someone know what can I do? Thank you, by by,

Laura.It seems to me that You have quoted Your string with the wrong character ()

You must use ' instead.sql
