The execute tag is meant for updates, inserts and deletes. What you
probably want to use is the resultSet tag.
<sql:resultSet id="myRS" >
<%
for( int i = 0; i < val.size(); i++ ) // What is val???
{
%> <sql:getColumn position="<%=i%>"/> <%
}
%>
</sql:execute>
I think you're trying to print all the values that are returned from your
query. I'm unsure of the origin of the variable 'val'. The resultSet tag
will loop through all the rows by default, I assume the 'for loop' is meant
to loop through all the fields in each given row in the result, thus
val.size() should return the number of fields you're selecting in your where
clause.

Sorry to repeat, but does anyone have a clue on this or should I go
about this a different way?

Hi everyone, Im new to the list so good to meet you.
Any pointers on why the following code is disallowed, and a quick way to
code around it? Apparently prepared statements do not allow run-time
resolution of the query string.
<sql:query>
select * from orders where <%= where %>
//"where" contains the where clause, with columnname=?
repeated.
//this build a dynamic query with varying number of
elements
</sql:query>
<sql:execute>
<% for(int i = 0; i< val.size(); i++){ %>
<sql:setColumn position="<%
out.write(String.valueOf(i)); %>">
<%= val.elementAt(0) %></sql:setColumn>
<% } %>
</sql:execute>
