body: <p>This is ThreadGroup:
  <img src="https://i.stack.imgur.com/akuVr.png" alt="this is ThreadGroup"></p>
  
  <p>This is JDBC Connection Config:
  ![this is JDBC CONNECTIIN CONFIG][2]</p>
  
  <p>The SQL:</p>
  
  <pre><code> SELECT siteid FROM tky_tab_bbsdata WHERE name = ?
  </code></pre>
  
  <p>And then it throws exception:</p>
  
  <blockquote>
    <p>java.sql.SQLException: ORA-01008: 并非所有变量都已绑定
    the request is :SELECT siteid FROM tky_tab_bbsdata where name = ?
    梁段
    VARCHAR</p>
  </blockquote>
  
  <p>I don't know how to solve this problem, the SQL may be right!</p>
