Order by clause + Union

Hi ,
i want to use "union" to combine 2 query results and also i need to apply order by clause in both queries,how i can achieve this
i.e
i wrote query like
select item_id from item_mst
where item_id <5
order by item_no
union
select item_id from item_mst
where item_id <10
order by item_no
But it is giving ORA-00933 error.
Please help me to over come this error.
Thanks in advance

You cannot have an ORDER BY clause on each part of the union - there is only one ORDER BY allowed and that applies to the result of the union.
select item_id from item_mst
where item_id <5
union
select item_id from item_mst
where item_id <10
order by item_idI'm assuming you meant 'order by item_ID', not item_NO, since there is no item_NO column in the query.

Order by clause with union

Hi,
I wanted to know if this is possible with order by clause and union. some how union messes up the ordering of the left part of the union statement.
assume the data is as below in table tab1
c1 c2
4 1
4 2
5 1
5 2
7 1
7 2
8 3
9 4
the expected output must be for all c1 < 7 ordering must be on c1 and for all c1 > 7 ordering must be on c2.
so the query i tried was
select c1,c2 from tab1 where c1 <7 order by c1
union
select c1,c2 from tab1 where c1 >=7 order by c2
it is giving the message 'Sql command not properly ended'.
Suggestions are welcome

Where to place ORDER BY clause when a query includes UNION

I have a query that has UNION in it. could you please tell me where to place the ORDER BY clause. Because it's throwing an error if i place the ORDER BY clause at the end

Because you are using the UNION set operator, you need to either specifically list your columns or use positional notation.
Without a set operator we can order by the column name without specifically listing it:
SQL> select * from dual
2 order by dummy;
D
X
1 row selected.This doesn't work once you introduce a set operator:
SQL> ed
Wrote file afiedt.buf
1 select * from dual union all
2 select * from dual union all
3 select * from dual
4* order by dummy
SQL> /
order by dummy
ERROR at line 4:
ORA-00904: "DUMMY": invalid identifierSo you need to either use positional notation:
SQL> ed
Wrote file afiedt.buf
1 select * from dual union all
2 select * from dual union all
3 select * from dual
4* order by 1
SQL> /
D
X

Using ORDER BY in UNION clause in cursor

Hi Everybody,
I have one situation and i need your help guys. I have to use ORDER BY in UNION of two queries and return value in cursor.
OPEN cursor FOR
SELECT ID, DESC,SID, ITID, SID_DESC
FROM (SELECT A.ID,
A.DESC,
B.SID,
NULL AS ITID,
B.SID_DESC
FROM TABLEA A, TABLEB B
WHERE A.ID = B.ID
order by A.SORTORDER asc,B.SORTORDER)
UNION
SELECT ID, DESC, ,SID,ITID, ITID_DESCRIPTION,
FROM (SELECT A.ID,
A.DESC,
NULL AS SID,
C.ITID,
C.ITID_DESC,
FROM TABLEA A,
TABLEC C
WHERE A.ID = C.ID
order by A.SORTORDER asc,C.SORTORDER)
I SORT ORDER is column in all three tables. TABLEA has unique number for each record as sort order. TABLEB has sortorder as 1 for each id. If id is two times then its 1 and 2 for each id. TABLEC has sort order as TABLEB, 1 for each id and if id is two times then it is 1 and 2 and id id is three times, it is 1, 2, 3.
I am not getting correct sorting as i cant use order by like this in UNION. Please let me know how i can handle this.
Thank you in advance to everybody.
I will really appreciate your comments and responses.

Hi,
You can use ORDER BY in a sub-query, but there's usually no point in doing so, because the super-query won't necessarily preserve that order. You need to make the columns that you want to ORDER BY available to the main query, so that they can be used there.
Try this:
SELECT      ID, DESC,SID, ITID, SID_DESC
FROM      (
         SELECT    A1.ID,
                    A1.DESC,
                B.SID,
                NULL          AS ITID,
                B.SID_DESC,
                A1.SORTORDER     AS sortorder_1
                B.SORTORDER     AS sortorder_2
         FROM      TABLEA     A1,
                    TABLEB     B
         WHERE     A1.ID = B.ID
    UNION
         SELECT    A2.ID,
                    A2.DESC,
                NULL          AS SID,
                       C.ITID,
                C.ITID_DESC,
                A2.SORTORDER     AS sortorder_1
                B.SORTORDER     AS sortorder_2
         FROM      TABLEA          A2,
                    TABLEC         C
         WHERE     A2.ID = C.ID
order by SORTORDER_1     ASC     -- ASC is the default, but it doesn't hurt to say it
       SORTORDER_2This assumes that tableb.sortorder and tablec.sortorder have the same, or at least similar, data types. If not, explicitly convert sortorder_1 in one branch of the UNION to the type of sortorder_2 in the other branch.
Using the same alias to mean different things in the same query is just asking for trouble. I changed the table alias a (which was used in different places to mean two different things) to A1 and A2, each of which means only one thing.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.

IN clause with ORDER BY clause in sub-queries

Hello,
We generate dynamic queries with the following statement pattern (could be many union/intersect sub-queries):
select my_col
from my_table
where my_col IN
select table_2.my_col , x_col from table_2 where x_col > 10
UNION
select table_3.my_col , y_col from table_3 where y_col > 20
INTERSECT
select table_4.my_col , z_col from table_4 where z_col is between 30 and 50
I know that I can do just the sub-queries w/ an ORDER BY clause as follows (as long as the 2nd parameter in the select stmts are of the same type):
select table_2.my_col , x_col from table_2 where x_col > 10
UNION
select table_3.my_col , y_col from table_3 where y_col > 20
INTERSECT
select table_4.my_col , z_col from table_4 where z_col is between 30 and 50
order by 2 desc
But my questions are:
1. What is (if there is) the syntax that will ensure that the result set order will be that of the ordering of the sub-queries?
Or does my SQL stmt have to have syntactically (but not semantically) change to achieve this?
Thanks,
Jim

just a minor doubt - I think it is not officially supported to have separate ORDER BYs in a compound query with set operators (e.g. UNION / UNION ALL subsets). Of course one could use inline views with NO_MERGE + NO_ELIMINATE_OBY hints, but I think the only officially supported approach is to use a single, final ORDER BY (that needs to use positional notation as far as I remember).
Randolf,
You're right, of course, about the separate "order by" clauses.
Interestingly the following type of thing does work though (in 10.2.0.3, at least):
with v1 as (
    select * from t1 where col1 = 'ABC' order by col2
v2 as (
    select * from t1 where col1 = 'DEF' order by col2
select * from v1
union all
select * from v2
;A quick check the execution plan suggsts that Oracle appears to be convering this to the following - even though its technically not acceptable in normal circumstances:
select * from t1 where col1 = 'ABC' order by col2
union all
select * from t1 where col1 = 'DEF' order by col2

Using Decode in Order By clause

Hi all,
I've a prblem with the DECODE in ORDER BY clause
Could you please advise if I did something wrong with my sort order.
Actually,I've a store procedure which gather all information from several tables and return with a resultset.
Therefore I just post an example table_resultset instead of lenghthy StoreProc in forum
/* table contain the column need to be sort on the resultset */
create table table_sort (sortnum,sortname) as
select 1553, 'IDNO' from dual union all
select 1231, 'IDNAME' from dual union all
select 1001, 'CREDATE' from dual;
/* a sample of some information that resultset return by a storeproc */
create table table_resultset (idno,idname,credate) as
select 1111, 'SORT ORDER', sysdate-7 from dual union all
select 54555, 'NEED A TEST CASE', sysdate+5 from dual union all
select 10012, 'BEYOND THE LIMIT', sysdate from dual union all
select 10522, 'CONCENTRATION', sysdate+20 from dual union all
select 01231, 'A VALIDATION', sysdate-3 from dual;
/* this select statement similar to execute a storeproc with s decode in the ORDER BY clause */
select * from table_resultset
order by decode((select ltrim(rtrim(sortname)) from table_sort where sortnum=1231),'IDNO',1,'IDNAME',2,3);
OR
select * from table_resultset
order by case (select ltrim(rtrim(sortname)) from table_sort where sortnum=1231)
when 'IDNO' then 1
when 'IDNAME' then 2
else 3
end;
Thanks.

Thanks for the tip Samb ... :)
I got it ... all sort field must be same datatype.

But if I want to sort the resultset by the column IDNO of table_resultset then I've a problem due to the field converted into character, and the field IDNO define as number(9) of a table in production. therefore I've to find a solution when that field convert into character must be same length in order to sort IDNO correctly. As you can see from below
SQL> select * from table_resultset
2 order by decode((select ltrim(rtrim(sortname)) from table_sort
3 where sortnum=1553),'IDNO',to_char(idno),'IDNAME',idname,to_char(credate,'yyyymmdd'));
IDNO IDNAME CREDATE

10522 CONCENTRATION 08-07-30
1111 SORT ORDER 08-07-03
1231 A VALIDATION 08-07-07
54555 NEED A TEST CASE 08-07-15
your suggestion always welcome.

Decode in order by clause

Is it possible to use a decode function in the order by clause, when you have two select statements with a union between? I seem to be getting an error-message telling me to type a number.

Order by clause...

Hi everyone,
How can i achieve this with order by clause
If i have the following data in my table. I need one record (which has the data 'Last record')
to be the last record for my select statement, and order the other records according to "no"
whatever data i have i need to arrange that record last
select * from
select 'A' order_by_test,5 no from dual
union all
select 'B' order_by_test,1 no from dual
union all
select 'C' order_by_test,8 no from dual
union all
select 'Last record' order_by_test,3 no from dual
union all
select 'Z' order_by_test,7 no from dual
union all
select null order_by_test,null no from dual
union all
select ' ' order_by_test,null no from dual
output:
=======
order_by_test     no
    B             1         -->other records ,order by no nulls last
    A             5
    Z             7
    C             8
   null           null
' '            null
Last record     3      ----> everytime this should be the last record of my select statement,I am sorry if it is a dumb question to ask.
Thanks in advance

Hi,
Use CASE (or equivalents) to map your values into sortable values.
ORDER BY CASE
                 WHEN order_by_test = 'Last record'
           THEN 2
           ELSE 1
             END
,       noIf the sort order depends on two different columns, it's often best to have two different expressions in the ORDER BY clause.
SET     NULL     [NULL]
select * from
select 'A' order_by_test,5 no from dual

Using order by in Union ALL

If i execute individually it works fine, if i use union all it throughs error for me.
Any suggestion...

Hi,
In a set operation (such as UNION) table aliases (such as b.) only have meaning within the branch in which they are defined. The ORDER BY clause is not part of any 1 branch, so a table alias can't be used there.
In most cases, you can use a column name (or alias) from the first branch, like this:
SELECT    b.audit_trail_id,
          TO_CHAR (b.last_update_date, 'DD-Mon-YYYY') "Revision Date",
order by "Revision Date"
;and you can always order by column number, like this:
SELECT    b.audit_trail_id,
          TO_CHAR (b.last_update_date, 'DD-Mon-YYYY') "Revision Date",
order by 2
;In this case, however, there's an extra problem. You're transforming the DATE to a string in the SELECT clause. The string is all that's available in the ORDER BY clause, and the string '19-NOV-2012' comes after the string '01-JAN-2015', because the character '1' comes after '0'. Perhaps the simplest solution is to have your front end, and not the query, format the dates. In SQL*Plus, you can do this:
ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MON-YYYY';
SELECT    b.audit_trail_id,
          b.last_update_date    AS "Revision Date",
order by 2
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Doubt regarding multiple criteria in order by clause

Hi, I don't understand the effect of multiple elements inside the order by clause. I have the following example table:
factor_x | factor_y | price
=====================
1 | 5 | 1000
2 | 4 | 6970
3 | 3 | 3688
4 | 2 | 9087
5 | 1 | 10000
=====================
So I tried: select price from pricetable order by factor_x; results as follows:
1000
6970
3688
9087
10000
Then: select price from pricetable order by factor_y; results as follows:
10000
9087
3688
6970
1000
Then: select price from pricetable order by factor_x, factor_y; results as follows:
1000
6970
3688
9087
10000
which is same as using order by factor_x. Can anyone tells me what is the effect of adding a 2nd, 3rd..... criterion in the order by clause? Because in this example I cannot see the difference. Many thanks.

Hi,
I did a little change in your data. Hope it will help you to understand.

Writing order by clause with user parameter

I have a user parameter where the user is supposed to choose what column they want to sort by.
And they can choose between k.personnr and k.personnavn. I am trying to do this with a decode function.
Now this would work fine if there was no union between these select statements.
But with the union I get a ORA-01785, where they tell me to put in a number.
Here is the sql:
SELECT
k.personnr as PERSON ,
k.personnavn as NAVN,
r.belop as SUM,
concat(to_char(r.bilagdato,'MM'), to_char(r.bilagdato,'YYYY')) AS MND,
PERIODE(concat(to_char(r.bilagdato,'MM'), to_char(r.bilagdato,'YYYY'))) AS PERIODE
FROM
reskontro r,
klient k,
kontoplan p,
konto c
WHERE
r.distriktnr='21'
and r.distriktnr=c.kontoid
and r.distriktnr=k.distriktnr
and r.personnr=k.personnr
and r.kontonr=p.kontonr
and (((r.bilagdato between :p_fra_dato and :p_til_dato) and (:p_fra_dato <= c.overfort) and (:p_til_dato <= c.overfort))
or ((r.bilagdato between :p_fra_dato and c.overfort) and (:p_fra_dato <= c.overfort) and (:p_til_dato >= c.overfort)))
UNION ALL
SELECT
k.personnr as PERSON ,
k.personnavn as NAVN,
(t.belop/100) as SUM,
concat(to_char(t.bilagdato,'MM'), to_char(t.bilagdato,'YYYY')) AS MND,
PERIODE(concat(to_char(t.bilagdato,'MM'), to_char(t.bilagdato,'YYYY')),:P_HORISONTAL) AS PERIODE
FROM
transaksjon t,
klient k,
kontoplan p
WHERE
t.distriktnr='21'
and t.distriktnr=k.distriktnr
and t.personnr=k.personnr
and t.kontonr=p.kontonr
and t.bilagdato between :p_fra_dato and :p_til_dato
This is the order by clause I would like to use:
order by decode(:p_order_by,'Personnavn',k.personnavn,k.personnr)
I also get an error when I use:
order by decode(:p_order_by,'Personnavn',2,1)
Can anybody tell me how to work around this problem?

Hi,
One way you can do to get around this problem could be :
select * from (
SELECT
k.personnr as PERSON ,
k.personnavn as NAVN,
r.belop as SUM,
concat(to_char(r.bilagdato,'MM'), to_char(r.bilagdato,'YYYY')) AS MND,
PERIODE(concat(to_char(r.bilagdato,'MM'), to_char(r.bilagdato,'YYYY'))) AS PERIODE
FROM
reskontro r,
klient k,
kontoplan p,
konto c
WHERE
r.distriktnr='21'
and r.distriktnr=c.kontoid
and r.distriktnr=k.distriktnr
and r.personnr=k.personnr
and r.kontonr=p.kontonr
and (((r.bilagdato between :p_fra_dato and :p_til_dato) and (:p_fra_dato <= c.overfort) and (:p_til_dato <= c.overfort))
or ((r.bilagdato between :p_fra_dato and c.overfort) and (:p_fra_dato <= c.overfort) and (:p_til_dato >= c.overfort)))
UNION ALL
SELECT
k.personnr as PERSON ,
k.personnavn as NAVN,
(t.belop/100) as SUM,
concat(to_char(t.bilagdato,'MM'), to_char(t.bilagdato,'YYYY')) AS MND,
PERIODE(concat(to_char(t.bilagdato,'MM'), to_char(t.bilagdato,'YYYY')),:P_HORISONTAL) AS PERIODE
FROM
transaksjon t,
klient k,
kontoplan p
WHERE
t.distriktnr='21'
and t.distriktnr=k.distriktnr
and t.personnr=k.personnr
and t.kontonr=p.kontonr
and t.bilagdato between :p_fra_dato and :p_til_dato)
order by decode(:p_order_by,'Personnavn', NAVN, PERSON)

Order by clause not working

Hi, everyone,
I am trying to use the following insert statement to insert records in asc order. if i use the select statement alone the order by clause works fine, but when i use the same sql and add a insert into table statment the order by clause does not work. I am not getting the records in ascending order. could anybody help me in this regard?
INSERT INTO cat_sales_stg
select      b.SSC,
     ltrim(rtrim(a.CAT_DESC)) cat_desc,
     SUM(a.AMOUNT) AMOUNT
FROM Trans a, SSC b
WHERE a.ACCOUNT_NUMBER = TO_CHAR(b.ACCOUNT_NUMBER)
     AND a.TMONTH >= 200905 AND a.TMONTH <= 200910
     AND a.FORMAT_NAME = 'ABC'
     AND b.BMONTH = 200910
     AND b.SAMPLE = 3
     AND b.BANNER_NAME = 'ABC'
     AND b.MODEL_NAME = 'XYZ'
group by b.SSC, ltrim(rtrim(a.CAT_DESC))
order by ssc,cat_desc
Thanks in advance

Hi, everyone,

That is completely outside the way relational databases are designed. You insert rows as unordered and use an ORDER BY clause in a SELECT when reading them. ORDER BY is for SELECT statements, not INSERT.
In particular Toon poined out that we can't control where individual rows get stored.
There is a databas object called a varray that can store data in sorted order. I have never seen them used because selecting the data back out again is more work; using an ordinary table and an ORDER BY clause is much easier.

Suppress "Order By" clause in Answers Query

Hello,
Is it possible to Suppress "Order By" clause in Answers Query.
I'm using a database view as data source. In the view definition, "order by" clause is already specified. Is it possible to get the same order in the OBIEE report??
I do not want to use Sort Order column in the repository.
Thanks,
Girish

You add a rownumber to your DB view and use that to 'sort' your report.
