>    To change data (perform an insert, update, or delete) 
    you use the <TT

>executeUpdate()</TT
> method.
    <TT
CLASS="FUNCTION"
>executeUpdate()</TT
> is similar to the
    <TT
CLASS="FUNCTION"
>executeQuery()</TT
> used to issue a select,
    however it doesn't return a <TT
CLASS="CLASSNAME"
>ResultSet</TT
>,
    instead it returns the number of records affected by the insert,
    update, or delete statement.
