title: SQL Error: ORA-00904: : invalid identifier
body: <p>I am an SQL rookie and I would very much appreciate some assistance on this rather basic issue.</p>
  
  <pre><code>alter table OCEAN_ANTENNE_TEMP
  add column ANT_TILT_M number(5) not null,
  ANT_FSC_ANT number(4,1) default 0;
  /
  </code></pre>
  
  <p>why is this query giving me this error:</p>
  
  <blockquote>
    <p>SQL Error: ORA-00904: : invalid identifier
        00904. 00000 -  "%s: invalid identifier"</p>
