Issue with Date used to Filter a Report

Question

I have the following source for a report. The source was working correctly before and I am trying to add a date filter to it.
q VARCHAR2(32767); -- query
w VARCHAR2(4000) ; -- where clause
w2 VARCHAR2(4000) ; -- where clause for salesrep
w3 VARCHAR2(4000) ; -- where clause for agent
w4 VARCHAR2(4000) ; -- where clause for date range
we VARCHAR2(1) := 'N'; -- identifies if where clause exists
BEGIN
q := 'SELECT "TBLCALL"."CALLID", "TBLSALESREP"."LNAME" || '', '' || "TBLSALESREP"."FNAME" as "SalesRep", "TBLAGENT"."LNAME" || '', '' || "TBLAGENT"."FNAME" as "Agent", "TBLAGENT"."AGENTID", "COMPLETEDATE", htmldb_util.get_since("CREATEDATE") as "Age", "CREATEDATE",
"TBLDIRECTOR"."DIRECTORNAME",
decode("CREQUESTID",NULL,''None'',"CREQUESTID") as "# REQUESTS", "REQUESTSTATUS", "ESCALATIONNAME" '
||
' FROM "#OWNER#"."TBLAGENT", "#OWNER#"."TBLSALESREP", "#OWNER#"."TBLDIRECTOR", "#OWNER#"."TBLCALL", "#OWNER#"."VW_CALLREQUESTS", "#OWNER#"."VW_CALLSTATUS", "#OWNER#"."VW_CALLESCALATION" '
||
' WHERE "TBLAGENT"."AGENTID" = "TBLCALL"."AGENTID"
and "TBLSALESREP"."DIRECTORID"="TBLDIRECTOR"."DIRECTORID"
and "TBLCALL"."CALLID"="VW_CALLREQUESTS"."CALLID"(+)
and "TBLCALL"."CALLID"="VW_CALLSTATUS"."CALLID"(+)
and "TBLCALL"."CALLID"="VW_CALLESCALATION"."CALLID"(+)
and "TBLSALESREP"."SALESREPID"="TBLCALL"."SALESREPID" ';
IF :P1_COMPLETED = '0'
THEN
w := ' COMPLETEDATE is null';
we := 'Y';
END IF;
IF :P1_COMPLETED = '1'
THEN
w := ' COMPLETEDATE is not null ';
we := 'Y';
END IF;
IF :P1_SELECT_SALESREP != '-1' THEN
w2 := ' AND TBLCALL.SALESREPID= :P1_SELECT_SALESREP ';
ELSE
w2 := '';
END IF;
IF :P1_SELECT_AGENT != '-1' THEN
w3 := ' AND TBLAGENT.AGENTID= :P1_SELECT_AGENT ';
ELSE
w3 := '';
END IF;
IF :P1_STARTDATE is not null AND :P1_ENDDATE is not null THEN
w4:= ' AND TBLCALL.CREATEDATE between ' || to_date(NVL(:P1_STARTDATE,'01/01/1900'), 'MM/DD/YYYY') || ' AND ' || to_date(NVL(:P1_ENDDATE,'12/31/9999'),'MM/DD/YYYY');
ELSE
w4 := '';
end if;
IF we = 'Y' THEN
q := q || ' AND ' || w || w2 || w3 || w4 ;
ELSE
q := q || w2 || w3 || w4;
END IF;
RETURN q;
END;
Each time I try to run the page... the report gives me the following error:
failed to parse SQL query:
ORA-00904: "OCT": invalid identifier
It looks like a date format issue, but I have tried several things to resolve it and it still does not work... What can I do?

Answer 1

I think you have a problem with format masks.
Check the format masks that are used in P1_STARTDATE and P2_STARTDATE
