I am facing for me strange issue with following parametrical cursor.
I have defined cursor in this way:
CURSOR cur_action ( product_code VARCHAR2(100) , action_master_list VARCHAR2(100))
IS
SELECT
act.ACTION_DETAIL_KEY,
act.ACTION_MASTER_KEY,
act.PRODUCT_CODE,
act.REF_ACTION_DETAIL_KEY
FROM XMLTABLE(action_master_list) x
JOIN ETDW.MFE_AR_ACTION_DETAILS act ON TO_NUMBER(x.COLUMN_VALUE) = act.ACTION_MASTER_KEY
WHERE 1=1
AND act.LAST_FLAG = 'Y'
AND act.PRODUCT_CODE = product_code;
Then I am using it in following way:
OPEN cur_action ( iFromProductCode , iActionMasterKeyList);
LOOP
FETCH cur_action BULK COLLECT INTO vActionDetailKey, vActionMasterKey, vProductCode, vRefActionDetailKey LIMIT 100;
FOR j IN 1..cur_action%ROWCOUNT
LOOP
dbms_output.put_line('vActionDetailKey: ' || vActionDetailKey (j) ||' vActionMasterKey: '|| vActionMasterKey (j) || ' vProductCode: ' || vProductCode (j));
END LOOP;
END LOOP;
Result seems to be unfilterd. It doesnt return 3 rows as expected result (this result is returned in with cusor query, when i run in outside procedure/pl block), but it returns all rows for actions in list. So it seems, that WHERE condition "act.PRODUCT_CODE = product_code" was not applied. Why?
Thank you
Why? Because you named parameter the same as column, so Oracle reads it as if it was where 1 = 1, i.e. no filtering at all.
Rename parameters to e.g.
CURSOR cur_action ( par_product_code V
----
this
and, later,
AND act.PRODUCT_CODE = par_product_code;
----
this
I have this code:
declare
sName varchar(25);
iRank number := 0;
sDesc varchar(510);
cursor q is
SELECT *
FROM trec_topics ORDER BY num;
BEGIN
for ql in q
loop
sDesc := replace(replace(replace(ql.title, '?', '{?}'), ')', '{)}'), '(', '{(}');
--dbms_output.put_line(ql.num||'-'||sDesc);
declare
cursor c is
SELECT /*+ FIRST_ROWS(100) */ docno,
CASE
WHEN SCORE(10) >= SCORE(20) THEN SCORE(10)
ELSE SCORE(20)
END AS SCORE
FROM txt_search_docs WHERE CONTAINS(txt, 'DEFINESCORE(ql.title, OCCURRENCE)', 10) > 0 OR
CONTAINS(txt, 'DEFINESCORE(sDesc, OCCURRENCE)', 20) > 0
order by SCORE desc;
begin
iRank := 1;
for c1 in c
loop
dbms_output.put_line(ql.num||' Q0 '||c1.docno||' '||lpad(iRank,3, '0')||' '||lpad(c1.score, 2, '0')||' myUser');
iRank := iRank + 1;
exit when c%rowcount = 100;
end loop;
end;
end loop;
end;
As you can see I'm doing select on two different tables, however, I need to change the standard score, as it did not perform well. I'm trying to use the DEFINESCORE clause that has this 'DEFINESCORE (query_term, scoring_expression)' format.
How can I call the table columns within this clause? That is, I need to call my columns instead of "query_term", as there are several documents to do the search. Because the way I’m calling him, he’s looking for exactly the term ql.title
Anyone a suggestion to help me with this problem?
I finally managed to solve it.
It was about:
create a variable: topics varchar (525);
store the column value: topics := replace(replace(replace(ql.title, '?', '{?}'), ')', '{)}'), '(', '{(}');
and after calling it in the CONTAINS clause: FROM txt_search_docs WHERE CONTAINS(txt, 'DEFINESCORE(('''||topics||'''), OCCURRENCE)', 1) > 0
I have below SQL as a part of a view. In one of the schema I am getting "String Concatenation is too long" error and not able to execute the view.
Hence I tried the TO_CLOB() and now VIEW is not throwing ERROR, but it not returning the result as well it keep on running..
Please suggest....

You can use the COLLECT() function to aggregate the strings into a collection and then use a User-Defined function to concatenate the strings:
Oracle Setup:
CREATE TYPE stringlist IS TABLE OF VARCHAR2(4000);
/
CREATE FUNCTION concat_List(
strings IN stringlist,
delim IN VARCHAR2 DEFAULT ','
) RETURN CLOB DETERMINISTIC
IS
value CLOB;
i PLS_INTEGER;
BEGIN
IF strings IS NULL THEN
RETURN NULL;
END IF;
value := EMPTY_CLOB();
IF strings IS NOT EMPTY THEN
i := strings.FIRST;
LOOP
IF i > strings.FIRST AND delim IS NOT NULL THEN
value := value || delim;
END IF;
value := value || strings(i);
EXIT WHEN i = strings.LAST;
i := strings.NEXT(i);
END LOOP;
END IF;
RETURN value;
END;
/
Query:
SELECT Iav.Item_Id AS Attr_Item_Id,
CONCAT_LIST(
CAST(
COLLECT(
La.Attribute_Name || '|~|' || Lav.Attribute_Value ||' '|| Lau.Attribute_Uom
ORDER BY ICA.DISP_SEQ,LA.ATTRIBUTE_NAME
)
AS stringlist
),
'}~}'
) AS ATTR
FROM your_table
GROUP BY iav.item_id;
LISTAGG is limited to 4000 characters unfortunately. So you may want to use another approach to concatenate the values.
Anyway ...
It is strange to see LISTAGG which is a rather new feature combined with error-prone SQL1992 joins. I'd suggest you re-write this. Are the tables even properly joined? It looks strange that there seems to be no relation between Loc_Attributes and, say, Loc_Attribute_Values. Doesn't have Loc_Attribute_Values a Loc_Attribute_Id so an attribute value relates to an attribute? It would be hard to believe that there is no such relation.
Moreover: Is it guaranteed that your classification subquery doesn't return more than one record per attribute?
Here is your query re-written:
select
iav.item_id as attr_item_id,
listagg(la.attribute_name || '|~|' || lav.attribute_value || ' ' || lau.attribute_uom,
'}~}') within group (order by ica.disp_seq, la.attribute_name) as attr
from item_attribute_values iav
join loc_attribute_values lav
on lav.loc_attribute_value_id = iav.loc_attribute_value_id
and lav.loc_attribute_id = iav.loc_attribute_id -- <== maybe?
join loc_attributes la
on la.loc_attribute_id = lav.loc_attribute_id
and la.loc_attribute_id = lav.loc_attribute_id -- <== maybe?
and la.locale_id = 1
left join loc_attribute_uoms lau
on lau.loc_attribute_uom_id = iav.loc_attribute_uom_id
and lau.loc_attribute_id = iav.loc_attribute_id -- <== maybe?
left join
(
-- aggregation needed to get no more than one sortkey per item attribute?
select ic.item_id, ca.attribute_id, min (ca.disp_seq) as disp_seq
from item_classification ic
join category_attributes ca on ca.taxonomy_tree_id = ic.taxonomy_tree_id
where ic.default_category = 'y'
group by ic.item_id, ca.attribute_id
) ica on ica.item_id = iav.item_id and ica.attribute_id = iav.attribute_id
group by iav.item_id;
Well, you get the idea; check your keys and alter your join criteria where necessary. Maybe this gets rid of duplicates, so LISTAGG has to concatenate less attributes, and maybe the result even stays within 4000 characters.
Xquery approach.
Creating extra types or function isn't necessary.
with test_tab
as (select object_name
from all_objects
where rownum < 1000)
, aggregate_to_xml as (select xmlagg(xmlelement(val, object_name)) xmls from test_tab)
select xmlcast(xmlquery('for $row at $idx in ./*/text() return if($idx=1) then $row else concat(",",$row)'
passing aggregate_to_xml.xmls returning content) as Clob) as list_in_lob
from aggregate_to_xml;
I guess you need to write a small function to concatenate the strings into a CLOB, because even when you cast TO_CLOB() the LISTAGG at the end, this might not work.
Here´s a sample-function that takes a SELECT-Statement (which MUST return only one string-column!) and a separator and returns the collected values as a CLOB:
CREATE OR REPLACE FUNCTION listAggCLob(p_stringSelect VARCHAR2
, p_separator VARCHAR2)
RETURN CLOB
AS
cur SYS_REFCURSOR;
s VARCHAR2(4000);
c CLOB;
i INTEGER;
BEGIN
dbms_lob.createtemporary(c, FALSE);
IF (p_stringSelect IS NOT NULL) THEN
OPEN cur FOR p_stringSelect;
LOOP
FETCH cur INTO s;
EXIT WHEN cur%NOTFOUND;
dbms_lob.append(c, s || p_separator);
END LOOP;
END IF;
i := length(c);
IF (i > 0) THEN
RETURN dbms_lob.substr(c,i-length(p_separator));
ELSE
RETURN NULL;
END IF;
END;
This function can be used f.e. like this:
WITH cat AS (
SELECT DISTINCT t1.category
FROM lookup t1
)
SELECT cat.category
, listAggCLob('select t2.name from lookup t2 where t2.category = ''' || cat.category || '''', '|') allcategorynames
FROM cat;

SQL Query to concatenate column values from multiple rows in Oracle
(10 answers)
Closed 8 years ago.
I have a package in oracle that contains one stored procedure. It takes a date as a input and a number as input, and outputs the data into a ref_cursor. The purpose of the stored procedure is to extract all of the "winning numbers" that correspond to a certain input date.
CREATE OR REPLACE PACKAGE GETWINNINGNUMBERSBYDATEPKG IS
TYPE lotgwndate_ref_cursor IS REF CURSOR;
PROCEDURE GetWinningNumbersDATE (lg_wndate IN date, lg_wnwgid IN number, lg_ref OUT
lotgwndate_ref_cursor);
END GETWINNINGNUMBERSBYDATEPKG;
This is the package body. Again, the purpose here is to extract all of the "winning numbers" that correspond to a certain date and "gameid" number. Then, I want to pair the "winning numbers" with the "game name" and "drawing date". (This is to extract records from lottery drawings)
PROCEDURE GetWinningNumbersDATE (lg_wndate IN date, lg_wnwgid IN number, lg_ref OUT
lotgwndate_ref_cursor) IS
BEGIN
OPEN lg_ref FOR
SELECT a.GAMENAME, b.DRAWINGDATE, c.BALLNUMBER
FROM GAMEDETAILS a
INNER JOIN WINNINGRECORDS b
on a.GAMEDETAILSID = b.GAMEDETAILSID
INNER JOIN WINNINGBALLS c
on b.WINNINGRECORDSID = c.WINNINGRECORDSID
WHERE b.DRAWINGDATE = lg_wndate
AND a.GAMEDETAILSID = lg_wnwgid;
END GetWinningNumbersDATE;
END GETWINNINGNUMBERSBYDATEPKG;
Here is the call procedure.
SET SERVEROUTPUT ON size 100000
DECLARE
v_cursor LOTTERYGAMEPKG.lotgwndate_ref_cursor;
v_gamename GAMEDETAILS.gamename%type;
v_drawingdate WINNINGRECORDS.drawingdate%type;
v_ballnumber WINNINGBALLS.ballnumber%type;
BEGIN
GETWINNINGNUMBERSBYDATEPKG.GetWinningNumbersDATE(lg_wndate =>
TO_DATE('06/08/2014','dd/mm/yyyy'), lg_wnwgid => '4', /*date/gamedetailsid #(1-4)*/
lg_ref => v_cursor);
LOOP
FETCH v_cursor
INTO v_gamename, v_drawingdate, v_ballnumber;
EXIT WHEN v_cursor%NOTFOUND;
DBMS_OUTPUT.PUT_LINE
(v_gamename || ',' || v_drawingdate || ',' || v_ballnumber);
END LOOP;
END;
This works, and returns:
NorthstarCash,06-AUG-14,10
NorthstarCash,06-AUG-14,11
NorthstarCash,06-AUG-14,15
NorthstarCash,06-AUG-14,16
NorthstarCash,06-AUG-14,21
However, I want it to return
NorthstarCash,06-AUG-14,10,11,15,16,21
Are there any ways to do this? I have looked at many other questions but none are addressing the same issue as mine. ORACLE 11g
If you use Oracle 11g, just modify your SELECT query using LISTAGG
PROCEDURE GetWinningNumbersDATE (lg_wndate IN date, lg_wnwgid IN number, lg_ref OUT
lotgwndate_ref_cursor) IS
BEGIN
OPEN lg_ref FOR
SELECT a.GAMENAME, b.DRAWINGDATE, LISTAGG(c.BALLNUMBER,',') WITHIN GROUP (ORDER BY c.BALLNUMBER) AS BALLNUMBER
FROM GAMEDETAILS a
INNER JOIN WINNINGRECORDS b
on a.GAMEDETAILSID = b.GAMEDETAILSID
INNER JOIN WINNINGBALLS c
on b.WINNINGRECORDSID = c.WINNINGRECORDSID
WHERE b.DRAWINGDATE = lg_wndate
AND a.GAMEDETAILSID = lg_wnwgid
GROUP BY a.GAMENAME, b.DRAWINGDATE;
END GetWinningNumbersDATE;
And the caller, has to be modified like below.
v_ballnumber VARCHAR2(4000);
So i'm in the middle of testing the accuracy of my normalized data by creating a tool to de-normalize the data for comparison. While doing this i was looking into learning new techniques for this tool over what i normally would do(which was using cursors and looping through an insert/update) So i came across two items i wanted to try which were bulk collections and the merge statement. My problem is i'm having some trouble finding the best way to utilize the bulk collection.
EDIT:
Okay so i found my problem/solution when it came to the bulk collection. It was in fact the way i was fetching it. Instead of using the forall statement i changed it to a for and added a loop underneath it. Which lead to the discoveries of more bugs. The way i was trying to call the values stored in the indx was being done wrong so i've rectified that. Now the only problem i seem to be having is with the error noted in the title. In my merge for some reason the first value i try to use in the insert throws the following error:
PL/SQL: ORA-38101: Invalid column in the INSERT VALUES Clause: "TMI"."MACHINE_INTERVAL_ID"
ORA-06550: line 92, column 7:
So what i would like to know now is why exactly i'm getting this error. I understand the concept that my insert value is invalid. but i do not fully understand why this is so.
This is the merge statement in question:

I'm 75% sure that my problem lies in how i'm trying to fetch the bulk collection as displayed in the code above. So my question is: How exactly should i be fetching the value from a bulk collection to utilize with the merging of data?
And suggestions or comments are greatly appreciated. Thank you.
If you use FORALL, what needs to follow is a single SQL statement that you will pass the entire collection to. If you simply want to iterate over the elements in the collection, you'd use a FOR loop.
The syntax for referring to the n-th element of a collection is collection_name(index).column_name.
So, if you want to iterate over the elements in the collection one by one, you'd want something like
FOR indx IN MACHINE_INTERVAL_ROW.FIRST..MACHINE_INTERVAL_ROW.COUNT
LOOP
MACHINE_INTERVAL_ID := machine_interval_row(indx).MACHINE_INTERVAL_ID;
START_DATE_TIME := machine_interval_row(indx).START_DATE_TIME;
<<more code>>
END LOOP;
If you're going to refactor your code, though, I'm not sure what benefit you get from having a local variable MACHINE_INTERVAL_ID rather than just using machine_interval_row(indx).MACHINE_INTERVAL_ID. I'm also not sure why you're executing half a dozen separate SELECT statements each of which return a single row rather than writing one SELECT statement that joins together all these tables and populates whatever local variables you want.
Your MERGE is also going to be problematic-- it doesn't make sense for both the source and the destination of a MERGE to be the same table-- I would expect you to get an error that Oracle couldn't generate a stable set of rows if it tried to execute that statement. You could change the source of your query to be a query against DUAL that selected all the local variables you've populated, I guess, i.e.
MERGE INTO TEST_MACHINE_INTERVAL TMI
USING (SELECT machine_interval_row(indx).MACHINE_INTERVAL_ID,
machine_interval_row(indx).START_DATE_TIME
FROM dual) OTMI
ON (TMI.MACHIN_INTERVAL_ID = OTMI.MACHINE_INTERVAL_ID)
If TEST_MACHINE_INTERVAL is going to start off empty, though, it sounds like you'd be better off not using a MERGE, not using a BULK COLLECT and just writing an INSERT ... SELECT that pulled all the data you want to pull. Something like
INSERT INTO test_machine_interval( machine_interval_id,
start_date_time,
<<more columns>> )
SELECT machine_interval_id,
last_value(start_date_time) over (partition by machine_interval_id
order by start_date_time asc
rows between unbounded preceding
and unbounded following ) last_start_date_time,
<<more columns>>
FROM machine_interval
