Why does this query give me an exception?
<pre><code>string updateIncomeData = @"INSERT INTO TEAM_FUNDS_DETAILS("
   + "COMPONENT_TYPE,COMPONENT_NAME,COMPONENT_AMOUNT, YEAR_FOR, MONTH_FOR)"
   + "VALUES(" + Convert.ToInt32(TeamFundDetailsEnumClass.ComponentType.Income) 
   + " , ?, ?," 
   + ddlYear.SelectedIndex + ", " + ddlMonth.SelectedIndex + ")"
</code></pre>

<p>This parametrized query gives me an exception that tells me that there is an error near "?". What is the error. Please correct it.</p>
