title: Python executemany function
body: <p>I have a problem when running <code>executemany</code> with cx_oracle </p>
  
  <p>WHen I run the following statement, I receive <code>ORA-01036: illeagal variablename/number</code></p>
  
  <p><code>infotext_list</code> is a list of strings that should be compared with the <code>"SOMETHING"</code>
  it looks like ["abc", "bcd", "def", ...] and every string in it should be compared with the SOMETHING in that other databasetable!</p>
  
  <pre><code>insert_stmt = 'INSERT INTO data_table (...) SELECT ... FROM other_table WHERE SOMETHING = ? '
  curs.executemany(insert_stmt, infotext_list)
  </code></pre>
  
  <p>If I iterate over the <code>infotext_list</code> and use the standard <code>execute()</code> method it just works fine but it takes forever.</p>
