title: python - pyodbc setting for increase package size in stored procedure params
body: <p>I'm using Python2.7 with <code>pyodbc==3.0.7</code> for connecting to SQL Server.</p>
  
  <p>Everything is OK, but when I call a stored procedure with a string parameter that has 480 characters, it returns below error:</p>
  
  <p>Code: </p>
  
  <pre><code>cursor.execute("{CALL SP_NAME(?)}", (param))
  </code></pre>
  
  <p>Error:  </p>
  
  <blockquote>
    <p>The driver did not supply an error!</p>
  </blockquote>
  
  <p>But when I call <code>SP</code> with less character count, it works.</p>
  
  <p>So, how can I increase transfer package size in pyodbc?</p>
  
  <p><strong>Note</strong>: This problem does not exists in Windows OS, but it appears in Unix OS.</p>
