Understanding mysterious Oracle JDBC errors - ORA-00911: invalid character

Question

I am making Java 1.6-JDBC-Oracle 11 code. I created a table called employee with id,name and age. I am getting the error - ORA-00911: invalid character. How can I fix this ?

Answer 1

Bohemian is exactly right. I don't see why this was so hard. If you pop the message into Google, you'll get this:

The semi-colon is the first problem noted.

Another recommendation: Don't do this.

catch(SQLException e){System.out.println("Exception: " + e);}

Do this instead:

catch(SQLException e){
    e.printStackTrace(); // better yet, log it.
}

It'll give you lots more information.

Answer 2

remove the ; from inside the query

Answer 3

Try removing the semi colon from the end of your SQL statement.

ie

static String query = "SELECT emp_id, emp_name, emp_age " +
    "FROM employee"; // no trailing ";" in the SQL
