At last - I've managed to get this to work! Is this documented anywhere at all - I just guessed it based on other people's code!
OK, to prove the example here is what I did:
I have a form referencing the DEPT table.
I created a item called 'Search' and of type button.
I created a 'custom' PL/SQL block and added the following code:
declare
v_deptno NUMBER;
begin
v_deptno := p_session.get_value_as_NUMBER(
p_block_name=> 'DEFAULT',
p_attribute_name => 'A_DEPTNO');
PORTAL30.wwa_app_module.set_target('http://server/pls/portal30/app_schema_name.EXAMPLE_SQL_REPORT.show?p_arg_names=_show_header&p_arg_values=YES&p_arg_names=_max_rows&p_arg_values= 25&p_arg_names=_portal_max_rows&p_arg_values=25&p_arg_names=DEPTNO&p_arg_values='| |LTRIM(TO_CHAR(v_deptno)),'CALL');
end;
Note: you need to reference the column with an 'A_' prefixing the columm name.
I left the name 'DEFAULT' as it is.
OK so I set this to a variable and now want to call a Report called EXAMPLE_SQL_REPORT which was created with the following code:
select * from scott.emp where deptno = :deptno;
The bind variable being the custom parameter for the report.
I called the new report with the PORTAL30.wwa_app_module.set_target procedure and put in the full URL path (in this example) of the server and report.
I hope this helps!
