Syntax in select statement

Could you please explain me where is the difference between passing integer to "where" clause and string.

if I use like this:

("select * from table_name where id=" + id)-return to me everything what i need exactly,

but in case when I use

("select * from table_name where name = " + myname)-

get error message:Too few parameters,expected 1

I got myname from the form like

<%String myname = request.getParameter("name")%>

What the problem?I just start to work with JSP

Thank's for everybody
