[sql] How can I solve ORA-00911: invalid character error?

I tried to execute an SQL INSERT with Toad for oracle:

INSERT INTO GRAT_ACTIVITY
   (UUID, IP_ADRESS, SEND_MAIL, DATE_CREA, DATE_UPD, CREATOR, CENTER, ETAT, REQUEST)
 VALUES('555-vgd9-pllkd-5513', '172.12.23.130', 'N', SYSDATE, SYSDATE, '1554', 'M18', 'I', 8842);
--COMMIT;

the GRAT_ACTIVITY table structure is as below:

CREATE TABLE CASH.GRAT_ACTIVITY
(
  UUID       VARCHAR2(64 BYTE) NOT NULL,
  IP_ADRESS  VARCHAR2(15 BYTE),
  SEND_MAIL  VARCHAR2(1 BYTE),
  DATE_CREA  DATE,
  DATE_UPD   DATE,
  CREATOR    VARCHAR2(4 BYTE),
  CENTER     VARCHAR2(4 BYTE),
  ETAT       VARCHAR2(1 BYTE),
  REQUEST    NUMBER
)

the error message:

ORA-00911: invalid character

Cause: identifiers may not start with any ASCII character other than letters and numbers. $#_ are also allowed after the first character. Identifiers enclosed by doublequotes may contain any character other than a doublequote. Alternative quotes (q'#...#') cannot use spaces, tabs, or carriage returns as delimiters. For all other contexts, consult the SQL Language Reference Manual.

Action: None

How can I solve it?

I'm using a 3rd party program that executes Oracle SQL and I encountered this error. Prior to a SELECT statement, I had some commented notes that included special characters. Removing the comments resolved the issue.

I had the same problem and it was due to the end of line. I had copied from another document. I put everythng on the same line, then split them again and it worked.

I encountered the same thing lately. it was just due to spaces when copying a script from a document to sql developer. I had to remove the spaces and the script ran.

Remove the semicolon ( ; ).

In oracle, you can use semicolon or not when u ran query directly on DB. But when u using java to ran a oracle query, u have to remove semicolon at the end.

Remove the semicolon (;), backtick (``) etc. from inside a query

If a special character other than $, _, and # is used in the name of a column or table, the name must be enclosed in double quotations. Link

The option(s) to resolve this Oracle error are:

Option #1 This error occurs when you try to use a special character in a SQL statement. If a special character other than $, _, and # is used in the name of a column or table, the name must be enclosed in double quotations.

Option #2 This error may occur if you've pasted your SQL into your editor from another program. Sometimes there are non-printable characters that may be present. In this case, you should try retyping your SQL statement and then re-execute it.

Option #3 This error occurs when a special character is used in a SQL WHERE clause and the value is not enclosed in single quotations.

For example, if you had the following SQL statement:

SELECT * FROM suppliers WHERE supplier_name = ?;
