SQL & PL/SQL :: ORDER BY In A Particular Order
Jul 17, 2012
oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production
"CORE 11.1.0.6.0 Production"
I have data like:-
event_idiss_nbr
171350 2012051WR
171350 2012041WR
171350 2011081CC
171350 2012041WA
171350 2012031WW
171350 2011081WW
171350 2011081CR
171350 2011081CA
The possible last two characters of the iss_nbr can be:-
WW, WR,WA,CR,CA,CC
And I want it to be ORDER BY as follows.
WR
WA
CR
CA
WW
CC
So for example, in above case, it should be
event_idiss_nbr
171350 2012051WR
171350 2012041WR
171350 2012041WA
171350 2012031WW
171350 2011081CR
171350 2011081CA
171350 2011081WW
171350 2011081CC
How can I do it while loading the table?

Which step in the following plan is the first step of execution
I reckon it is "TABLE ACCESS BY INDEX ROWID| BANK_BATCH_STATE"
Is that correct?
In the "Predicate Information (identified by operation id):"
section the predicates - access and filter for the step "TABLE ACCESS FULL | PYMNT_DUES" are displayed first
Isn't there any relation between the order of execution steps and the order in which predicates are displayed?

I have below tables,
describe rpthead
Name Null Type
--------------------------- -------- -------------
RPTNO NOT NULL NUMBER
RPTDATE NOT NULL DATE
RPTD_BY NOT NULL VARCHAR2(25)
PRODUCT_ID NOT NULL NUMBER
describe rptbody
Name Null Type
------------- -------- -------------
RPTNO NOT NULL NUMBER
LINENO NOT NULL NUMBER
COMMENTS VARCHAR2(240)
UPD_DATE DATE
The fact is that we store some header in RPTHEAD and store real data in RPTBODY, the question is that if I use below SQL to query all data for a 'PRODUCT_ID'.
SELECT t0.LINENO, t0.COMMENTS, t0.RPTNO, t0.UPD_DATE
FROM RPTBODY t0 , RPTHEAD rpthead
WHERE
(
t0.RPTNO = rpthead.RPTNO
AND
t0.UPD_DATE>=to_date('1970/01/01 00:00:00','YYYY/MM/DD hh24:mi:ss')
AND
rpthead.PRODUCT_ID IN ('4647')
)
I do not want to have 'ORDER by' clause since data set is too large, the sorting takes long time, is there any way to get the result rows in the order sorted by RPTNO? We have the index for RPTNO on RPTBODY.

I am having table without any primary key. In this table, only inserts and deletes are performed , no update operation.
Is it safe to use order by rowid on such a table ? Does by applying order rowid, is it possible to check order in which rows were inserted in this table ?

In a query which gets executed first:
Select clause or Order by clause? First the columns specified in the select clause are fetched and then ordered or is it the vice -versa? In a query if a psuedo-column rownum is selected, then if we use order by on the rownum column, what happens?
What would be the output of the following query and why?Which part of the query is first executed, is it select clause or order by clause?
select empno,ename,rownum from emp order by rownum desc;

I am having trouble with tab order on a Form.
I rearranged the fields on a form, so I want the tab order to be different. I rearranged the fields in the object navigator to be in the order I want them to tab. I made sure the Previous Navigation Item and Next Navigation Item were set to null for all the fields.
Still it keeps the old tab order.
I also tried explicitly specifying the Previous Navigation Item and Next Navigation Item. Same thing, it kept the old tab order before I rearranged the fields. Previous Navigation Item and Next Navigation Item are both null.
There are no triggers on these fields. All fields are in the same block. I am using Oracle Form Builder version 9.

1,10,11,2,....like that.

I have requirement to create an XML structure through stored procedure. I need to Order some of the columns in ascending order before I format them into the xml structure. I am pretty novice to creating an output into XML format, but attached is the query I came up with (without order by). This works perfect, but now the requirement is to order by - cls_cd, and within cls_cd, again order by - cat_cd. I am not able to do this.

I've got a TRANSACTION table with about 4, 681 transactions going on over the course of a given year (this is a project for my DB class). I'm trying to create a query that will give the base revenue for each month in that year; so far I've come up with the following:
SELECT DISTINCT
CASE
WHEN EXTRACT(MONTH FROM transaction_date) = 1 THEN 'JAN' || ' ' || EXTRACT(YEAR FROM transaction_date)
WHEN EXTRACT(MONTH FROM transaction_date) = 2 THEN 'FEB' || ' ' || EXTRACT(YEAR FROM transaction_date)
WHEN EXTRACT(MONTH FROM transaction_date) = 3 THEN 'MAR' || ' ' || EXTRACT(YEAR FROM transaction_date)
WHEN EXTRACT(MONTH FROM transaction_date) = 4 THEN 'APR' || ' ' || EXTRACT(YEAR FROM transaction_date)
[code]....
The query returns twelve months, but they're all jumbled up. I tried extracting the month in the ORDER BY subclause
ORDER BY EXTRACT(MONTH FROM TO_DATE(month, 'MM YYYY'));
But I got an ORA-01866: the datetime class is invalid. I'm using Oracle 10g xe (outdated, I know). get the months to show up in order?

I have a varchar2 column which can hold numeric values, and also varchar2 values.
The following select returns only the records which have a number value in that column
select * from my_table
order by decode(
replace(translate(valoare,'1234567890.','00000000000'),'0',''), NULL,
valoare, 0 ) != 0;
But how can i order that column, so that first are the numbers (also ordered), and then the varchar2 columns (so all the rows of that table are selected, both varchar2 values and numbers in that column)? Is it possible?

I have a requirement where I need to display a list of employees, performance rating and manager id. I want to display the employees first whose manager is as manager_id as input parameter. So lets say a manager logs in, he should see his reporters first and then the rest. How can I implement this in SQL? I am trying first clause with order by but not sure how to do that here.
procedure
display_list(manager_id in varchar2)
Output is:
emp_id
manager_id
performance_rating

i have a table test on 4 different-different database, at the starting structure is same in all the database. and now i want to change the datatype of the primary key column named "testid" , then i add a temp column in test table (and it is added at the last in table).
i have copied the data of testid in temp column and renamed it as testid and i dropped the testid column , then the problem is that primary key column will comes at last and i want to make it like previous position so that there will not be any difference in all 4 database as in structure.
is it possible to changing column order as our desire without dropping the table?and i made all the script to changing the datatype of primary key column.

I have given below example.I hope that is clear.
M_STR_1 VARCHAR2(1000);
M_STR_2 VARCHAR2(1000);
BEGIN
M_STR_1 :='CHANDAN,RATTAN,PL,SQL';
M_STR_2 :='PL,SQL,RATTAN,CHANDAN,WINDOWS,LINUX';
--Output should like this same as order of M_STR_1
M_STR_2 :='CHANDAN,RATTAN,PL,SQL,WINDOWS,LINUX';
I think approach should be like take 1st word (before ,)and search the position in M_STR_1
and assign the that position in another variable using ltrim or rtrim. Well this what is i think

I have a query to pull the first contact of students.
The table has all contacts like parent/guardian, friends family, emergency contact etc.
I would like to the first primary contact in this order,
1. initial contact, 2. same as student address and also have to be parents,
3. live with and also a parent, 4. parents 5. friends.
I don't know how to pull 2 and 3 . because it looks like it needs to concatenate the columns.
here is my initial query
Select Min(U2.Id) Keep (Dense_Rank First Order By U2.Initial_Contact Desc, U2.Same_As_Students_Address Desc,u2.lives_with DESC,U2.Guardian Desc)
From Contacts
how to achieve 2 and 3?
The table script is attached. All the above columns are 1 or 0.
