title: SQL*Loader - How can i ignore certain rows with a specific charactre
body: <p>If i have a CSV file that is in the following format</p>
  
  <pre><code>"fd!","sdf","dsfds","dsfd"
  "fd!","asdf","dsfds","dsfd"
  "fd","sdf","rdsfds","dsfd"
  "fdd!","sdf","dsfds","fdsfd"
  "fd!","sdf","dsfds","dsfd"
  "fd","sdf","tdsfds","dsfd"
  "fd!","sdf","dsfds","dsfd"
  </code></pre>
  
  <p>Is it possible to exclude any row where the first column has an exclamation mark at the end of the string.
  i.e. it should only load the following rows</p>
  
  <pre><code>"fd","sdf","rdsfds","dsfd"
  "fd","sdf","tdsfds","dsfd"
  </code></pre>
  
  <p>Thanks</p>
