even if I copy and paste I still have the same error message.
INVALIDE CARACTERE. ORA-00911
Hi Rashad1974,
Try running the following query and tell me if it results with the same error:
SELECT USERNAME FROM ALL_USERS
WHERE USERNAME LIKE 'A%';
Also, determine what character set you are running on the system if possible
by running:
SELECT * FROM SYS.PROPS$
WHERE NAME LIKE 'NLS%';
Then post the NLS_LANGUAGE, NLS_CHARACTERSET and NLS_NCHAR_CHARACTERSET VALUES here.
My suspicion is that either you're having some internal issues with your system
or there may be a problem with your installed characterset prohibiting you from executing your query.
Thanks.
