Hi.

I have to write a procedure to define dynamic fields for my query and the only dynamic
way i need to pass dynamic number of argument is throught a varchar2 table. But the problem is that
the function DBMS_SQL.DEFINE_COLUMN doesn't accept table type variables.
I'm using Oracle Web Server 2.1 / WIN NT4.

Any help would be apreciated.

Thanx in advance.

here's a sample of the code i wrote :

procedure DynaQuery2 ( TableLabels in owa_util.ident_arr,

			TableValeurs in owa_util.ident_arr,
			TableSelect in owa_util.ident_arr,
			QueryTable in varchar2,
			HtmlBloc out varchar2 ) is

-- owa_util.ident_arr is defined as folows : type ident_arr is table

of varchar2(30) index by binary_integer; DynColumns owa_util.ident_arr;

begin

The Dynamic string has already been built

...... SNIP ........

		for i in 1..elem loop
		   if TableSelect(i) IS NULL then exit; end if;

DBMS_SQL.DEFINE_COLUMN(ReqCursor,i,DynColumns(i),30);

end loop;

...... SNIP ........

          loop
	  ignore := DBMS_SQL.FETCH_ROWS(ReqCursor);
      	  if ignore >0 then
  		begin
			
		  for i in 1..elem loop
  	  	    DBMS_SQL.COLUMN_VALUE(ReqCursor,i,DynColumns(i));
		end loop;

....... SNIP .........
