Dynamic SQL statements

Question

Hi
Here is an interesting question for all. My application has to support 5 markets. For that I created a report based on querying a view. That report is based on some search criteria which comes through a form. Right now the report is perfectly working as I have queried it as
select * from portland.rsu_inventory where ne = :ne_no
But we have some more markets apart from PORTLAND. For that we want to use the same application. So we have to be able to pass the market name dynamically. I am able to capture the market name in the search croteria form. But how can I send the market name to the Report SQL statement like
select * from | |MarketName| |.rsu_inventory where ne = :ne_no
Here the "MarketName" should be the market name that I would dynamically pass.
How can I acieve this. Thanks for any kind of suggession.

According to the metalink, the new version of OracleAs Portal is no longer support the query statement passing to this wwv_render_report.show procedure but however you can pass the cursor handle to this procedure instead. Here is the sample code to call this procedure:
declare
v_qry_stmt varchar2(32767) ;
v_cur_hdl int;
begin
v_cur_hdl := dbms_sql.open_cursor; -- open cursor
v_qry_stmt := '<your query>';
--Example query:
--v_qry_stmt := 'select empno,ename from scott.emp';
dbms_sql.parse(v_cur_hdl, v_qry_stmt, dbms_sql.native);
PORTAL30.wwv_render_report.show(p_table_border=>'1',
p_heading_bgcolor=>'#FFFFF0',
p_heading_font_face=>'Arial',
p_heading_font_size=>'13',
p_table_bgcolor=>'#FFFFFF',
p_font_face=>'Arial',
p_font_size=>'10',
p_query=>to_char(v_cur_hdl),
p_col_headings=>PORTAL30.wwv_standard_util.string_to_table2('Employee Number:Employee Name')
end;
