Help in writing a query!
Dear All,
My database is 11gR2 on Linux.
I am struck in writing a difficult query, need help from your guys.
I have a table, an application is controlling the columns of this table. Columns are added by the application.
This is the structure of the table:
create table imran_test(
2 username varchar2(100),
3 layer1 number(1),
4 layer2 number(2),
5 layer3 number(2));
-- where layer1, layer2, layer3.... are increased up to layer 22 and could be increased more...
Now each username will have 1 in any one of the layer, and all other layers will have 0
Like if I consider the above table this could be the sample data:
imran 1 0 0
hafeez 0 1 0
james 0 0 1
Now the result my query should return is:
select username, <column name where value is 1> and value of it, as per sample data, this should be return by the query:
imran layer1 1
hafeez layer2 1
james layer 3 1
Note: Please remember the columns are not fixed, they are added/altered by application.
Regards,
Imran
The table design is incorrect as it is not in 3NF and has a repeating group
You should correct the 'design' first or turn the layer... columns in a VARRAY.
Also my feeling is you should change your subject line 'Help in writing a query!' in 'Write my query' as that is what you actually ask, and leave out the exclamation mark.
Basically you dump everything in this forum, and being a bit less demanding might suit you better.
Also you still act rude by not marking your questions as answered.
Change that

Need help with writing a query with dynamic FROM clause
Hi Folks,
I need help with an query that should generate the "FROM" clause dynamically.
My main query is as follows
select DT_SKEY, count(*)
from *???*
where DT_SKEY between 20110601 and 20110719
group by DT_SKEY
having count(*) = 0
order by 1; The "from" clause of the above query should be generated as below
select 'Schema_Name'||'.'||TABLE_NAME
from dba_tables
where OWNER = 'Schema_Name'Simply sticking the later query in the first query does not work.
Any pointers will be appreciated.
Thanks

Remember that anything inside quotes is case-sensitive. Is the owner really "Schema_Name" with a capital S and a capital N, and 8 lower-case letters?
Simply sticking the later query in the first query does not work.Right; the table name must be given when you compile the query. It's not an expression that you can generate in the query itself.
Any pointers will be appreciated.In SQL*Plus, you can do something like the query bleow.
Say you want to count the rows in scott.emp, but you're not certain that the name is emp; it could be emp_2011 or emp_august, or anything else that starts with e. (And the name could change every day, so you can't just look it up now and hard-code it in a query that you want to run in the future.)
Typically, how dynamic SQL works is that some code (such as a preliminary query) gets some of the information you need to write the query first, and you use that information in a SQL statement that is compiled and run after that. For example:
-- Preliminary Query:
COLUMN my_table_name_col NEW_VALUE my_table_name
SELECT table_name AS my_table_name_col
FROM all_tables
WHERE owner = 'SCOTT'
AND table_name LIKE 'E%';
-- Main Query:
SELECT COUNT (*) AS cnt
FROM scott.&my_table_name
;This assumes that the preliminary query will find exactly one row; that is, it assumes that SCOTT has exactly one table whose name starts with E. Could you have 0 tables in the schema, or more than 1? If so, what results would you want? Give a concrete example, preferably suing commonly available tables (like those in the SCOTT schema) so that the poepl who want to help you can re-create the problem and test their ideas.

Hi Folks,
I'm trying to write a query to retrive the following information regarding snapshots. I tried lot of ways and couldn't get the solutions so seeking your help...

db name of snapshot site
snapshot name and their base table
refresh type (if it is fast, please list he snapshot log used)
refresh group which snapshot belongs to
dbms_job number which perform the refresh, job current status
refresh frequency
last refresh time
thanks
KarthikIf you tried a lot of ways ... post your work and show us what you have done.
What you are being asked to do is query data dictionary views. Do you know which ones?
SELECT view_name
FROM all_views
WHERE view_name LIKE '%<you fill this in>%';That is all the hints you get until you show your work. -

A 1/1/2011 500
Please suggest me...
Thanks.With UNPIVOT you can "name" each of your rows using as.
One trick is to "name" the rows to a number - then you can add that number of weeks to your start date - like this:
with t as (
select 'A' unit, DATE '2011-01-01' startdate, 100 period1, 200 period2 ,300 period3, 400 period4 ,500 period5 from dual
select
unit,
startdate + numtodsinterval(week*7,'day') startdate,
qty
from t
unpivot(
qty for week in (
period1 as 0,
period2 as 1,
period3 as 2,
period4 as 3,
period5 as 4
;Theoretically the above should work - but somehow I get a NULL date on my 11.1 instance? And I don't have another version to test with, alas.
But try it and see if it works on your instance ;-) -
Hi All,
I have a table with below structure & Data.
{code}
CREATE TABLE SAMPLE
(PARENT VARCHAR2(100),
CHANGE VARCHAR2(100),
FLAG VARCHAR2(10),
CHILD VARCHAR2(100))
{code}
{code}
insert into sample values('5762','7219','A','5965');
insert into sample values('5762','7219','A','83653');
insert into sample values('5762','7219','A','62714');
insert into sample values('5762','7219','A','108258');
insert into sample values('5762','7219','A','35203');
insert into sample values('5762','7219','A','35758');
insert into sample values('5762','7219','A','104522');
insert into sample values('5762','7219','A','70087');
insert into sample values('5762','7219','A','123878');

insert into sample values('5762','8058','D','35203');
insert into sample values('5762','8058','A','43782');
{code}
I want to delete the records where the flag is 'D',also I want to delete the record if the same child had added(Flag 'A') in the earlier change orders .
For ex: child 35203 has been removed from 8058,same child had added in change 7219,which should be removed.
Output would be like this.
{code}
insert into sample values('5762','7219','A','5965');
insert into sample values('5762','7219','A','83653');
insert into sample values('5762','7219','A','62714');
insert into sample values('5762','7219','A','108258');
insert into sample values('5762','7219','A','70087');
insert into sample values('5762','7219','A','123878');
insert into sample values('5762','7219','A','124098');
