title: Deleting records using prepared statement with more than 2 parameters
body: <p>I am using prepared statement for doing some operations on my database. I have table as below:</p>
  
  <pre><code>+--------------------------------------------------------+
  |Field  |    Type  |    Size |   Key  |  Text            |
  +--------------------------------------------------------+           
  |X1DEL  |  Char    |     1   |     2  | Status           |  
  |X1CMP  |  Zoned   |     3   |     1  | Company No.      | 
  |X1ORD  |  Zoned   |     9   |     2  | Order Number     | 
  |X1TYPE |  Char    |     1   |     1  | Transaction Type |
  |X1ORDT |  Zoned   |     8   |     0  | Order Date       |
  |X1CUST |  Char    |    10   |     0  | Customer Number  |
  |X1PO   |  Char    |    20   |     0  | PO Number        |
  |X1OTOT |  Zoned   |    11   |     2  | Order Total      |
  +--------------------------------------------------------+
  </code></pre>
  
  <p>I am doing one delete query as <code>delete from my_table where field=?</code> for single parameter.
  I have created query for 2 parameters as <code>delete from my_table where field=? and type=?</code>
  Again now i want to execute query for 4 to 5 parameters. I am writing a query as <code>delete from my_table where field=?,type=?,size=? and key=?</code> 
  I have tried for this query but not getting result.</p>
