ORA-00911: invalid character
Ensure that your SQL statement does not contain any invalid special characters. For example, remove any semicolons within the SQL command.
Ensure that you do not have an extra semicolon at the end of the SQL statement. For instance:
-- Incorrect: SELECT * FROM employees;; -- Correct: SELECT * FROM employees;
Make sure that all symbols and characters used in the SQL query are valid in Oracle SQL. Avoid using unsupported symbols.
Check the SQL query for any typographical errors or incorrect syntax. Ensure that the query follows Oracle SQL standards.
Consider the following SQL query:
SELECT * FROM employees WHERE first_name = 'John';
If the query mistakenly includes an invalid character, such as a semicolon within the query:
SELECT * FROM employees WHERE first_name = 'John;'
Solution: Remove the invalid character:
Consider the following SQL script:
SELECT * FROM employees; ;
Solution: Remove the extra semicolon:
SELECT * FROM employees;
Consider the following SQL query with unsupported symbols:
SELECT * FROM employees WHERE name = 'John#Doe';
Solution: Remove or replace unsupported symbols:
SELECT * FROM employees WHERE name = 'John Doe';
