I have the following SQL code in my report which worked at one time. But now
I get ORA-00904 invalid column name

Can anyone tell me what is wrong?

( p.hr_id = hr_b.hr_id ) and
( p.orig_id = hr_a.hr_id ) and
( p.venid_num = v.venid_num ) and
               ( pli.department_id between :FrmDpt and :ToDpt) and
               ( p.req_create_date between :FrmDte and :ToDte) and
               ( p.purchase_type in ( &Type ) )
Order By p.po_requistn_id,

Answer 1

Bogdan,
I am using a lexical parameter and I have a AFTERPFORM
function AfterPForm return boolean is
begin
IF :Type = 'All' THEN
:Type :='(''Capital'',''Standard'',''Blanket'',''Commodity'',''Invtyreq'',''Service'',''SMPO'')';
END IF;
IF :Type ='NonCapital' THEN
:Type := '(''Standard'',''Blanket'',''Commodity'',''Invtyreq'',''Service'',''SMPO'')';
END IF;
IF :Type ='Capital' THEN
:Type :='(''Capital'')';
END IF;
Return(TRUE);
end;
The SQL should look like this after the parameter has been entered.
( p.purchase_type in ('Capital','Standard','Blanket','Commodity','Invtyreq','Service','SMPO'));
If the user slects All as a parm.
