title: Insert SQL command wrong character issue
body: <p>I have this portion of code in Oracle 10g Express Edition:</p>
  
  <pre><code>CREATE TABLE SALARY (
     GRADE               number(1),
     LOSAL               number(4),
     HISAL               number(4));
  
     INSERT INTO SALARY VALUES (1,700,1200);
     INSERT INTO SALARY VALUES (2,1201,1400);
     INSERT INTO SALARY VALUES (3,1401,2000);
     INSERT INTO SALARY VALUES (4,2001,3000);
     INSERT INTO SALARY VALUES (5,3001,9999);
  </code></pre>
  
  <p>and I want to enter it like a SQL command, the problem is that when I hit the Run button I got the following message:</p>
  
  <blockquote>
    <p>ORA-00911: invalid character</p>
  </blockquote>
  
  <p>I have checked the syntax, but everything seems to be fine, does anybody see any mistake?</p>
