Help on writing this query.

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...
Can you send me a query that will give me all this information.
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
Karthik

If 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.

Hi need help in writing this query

A table has three columns - id (primary key), categoryID (numeric) and
amount (numeric). The goal is to provide a query that would show categoryID
and sum of amounts within that category where categoryID is an odd number
and sum of amounts is greater than 100,000

select categoryid,sum(amount) from table where mod(categoryid,2)=1
group by categoryid
having sum(amount) > 100000

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

When you see something like ...
   7 - filter(TO_NUMBER("C"."RESTART_FLAG")=0)                                                                                    It means that Oracle had to do a conversion for you since you aren't using the proper data type in your query.
That would mean IF there is an index on that column, it won't be useable...

Need help in writing the query

The initial data is as follows:
ID PARENT_ID
=============
1 NULL
2 NULL
3 2
4 6
5 3
6 7
7 4
8 NULL
but output is as follows in such way that Parent_Id should be displayed in ID place
ID PARENT_ID
=============
1 NULL
2 NULL
3 2
8 NULL
6 8
4 6
5 3
7 4
Can any one help how resolve this query?
Thanks in advance

Your output is inconsistent with initial data :) But
select * from t start with parent_id is null connect by parent_id = prior id;

Plz help me design this query

Hi,
Can you’ll please help me with this query.
Here is a little bit of background:
One title can have multiple items associated with it.
Table: TITLE has the master list of titles. TITLE_ID is the primary key.
Table: ITEM has the master list of all items. ITEM_ID is the primary. This table also has the TITLE_ID which stores title for this item.
Table: ITEM_STATUS has fields ITEM_ID and STATUS_ID. This field contains statuses for items. But not all items contained in the table ITEM are in this table.
I want to find TITLE_ID’s whose all items (all ITEM_ID in table ITEM having same value for TITLE_ID) have a particular status (for example STATUS_ID = 2) in table ITEM_STATUS.
Let’s say TITLE_ID = 1 has 5 items in table ITEM_ID and only 4 items out of it in table ITEM_STATUS with STATUS_ID = 2, then this TITLE_ID should not come. OR
Let’s say TITLE_ID = 1 has 5 items in table ITEM_ID and all these 5 items are in table ITEM_STATUS but only 1 has STATUS_ID = 2, then this TITLE_ID should also not come
In the above case only if all 5 items are contained in table ITEM_STATUS have STATUS_ID = 2 then this TITLE_ID should be reported by the query.
What should be the query like for this one, I am fairly new to SQL so plz guide me.
Thank you,
Raja

I haven't tested the query below. Try it and let me know for any issues:

                    item_status its
WHERE     t.title_id = i.title_id
     AND     i.item_id = its.item_id
     AND     NOT EXISTS     (
                                                       SELECT 1
                                                            FROM item_status its1
                                                       WHERE its1.item_id = i.item_id
                                                            AND status_id <> 'YOUR_ITEM_STATUS'

Please help to rewrite this query for better performance. This is taking long time to execute.
Table t_t_bil_bil_cycle_change contains 1200000 rows and table t_acctnumberTab countains 200000 rows.
I have created index on ACCOUNT_ID

   set account_number =
       ( select distinct b.account_number
         from rbabu.t_acctnumberTab b

ACCOUNT_ID              NUMBER(10)
ACCOUNT_NUMBER          VARCHAR2(24) Y

Ishan's solution is good. I would avoid updating rows which already have the right value - it's a waste of time.
You should have a UNIQUE or PRIMARY KEY constraint on t_acctnumberTab.account_id
merge rbabu.t_t_bil_bil_cycle_change a
using
      ( select distinct account_number, account_id
from rbabu.t_acctnumberTab
      ) t
on    ( a.account_id = b.account_id
       and decode(a.account_number, b.account_number, 0, 1) = 1
when matched then
update set a.account_number = b.account_number

Hi,
Welcome to the forum! You'll find that there are many qualified people (such as Tubby) willing to help you. Will you do what you can to help them? In order to simplify the query you posted,someone will first have to understand what it does, what the tables that it uses are like, and what tools you have to work with (that is, what version of Oracle, and any other software you are using). To actually test their ideas, people will need versions of your tables.
Many people, if they spent enough time, might be able to figure out roughly what you are doing, make some tables themselves and test a solution. You can help with all of that. I assume you already know what the appliction is, and what this particular query is supposed to do: you don't have to figure out any of that, you just have to say it. You know what all your tables are, what the datatypes of all the columns are, and what kinds of data are in the tables: you don't have to guess at any of that.
Describe what you're doing. Think about it: how do we know that
SELECT NULL
FROM dual;doesn't do what you want?
Post CREATE TABLE and INSERT statements for a little sample data.
Post the results that this query is supposed to produce from those results. (Is it producing the right output now? Then it should be easy to post the correct results.)
Describe, as well as you can, how the present query is doing it.
Format your existing code, so it's easy to see what the different branches of the UNION are, and what the main clauses are in each one.
When posting formatted text (code or results) type these 6 characters
\(all small letters, inside curly brackets) before and after each formatted section, to keep this site from compressing the spaces.
Say what versions of Oracle (e.g. 10.2.0.3.0) and any other relevant software you are using.
I know it's a lot of work, but it really helps. You can do it as well (probably better) than anyone else, and if you're unwilling to do it, why should anyone else be willing?

   where t.individual = pt.ID) as current_grade
      ,(select grades from mappingt2 ty
   where ty.individual = pt.name) alt_grade
      ,pt.place
FROM t2 ptI was just wondering whether this query can be better written. All help is appreciated. Thank you

if your goal is to optimize your query for initial response time, you may want to use the former query, with the scalar subquery, because Oracle Database would have to get just the first row from DEPT, run the scalar subquery (select count...) against EMP to get the count, and then return it. The process for returning that first row would be very fast.

The corollary to this that was not explicitly mentioned in the article that I can see is that this probably comes at the expense of the time taken to return all the rows which can then take longer.

Is there any better way of writing this query??

I have a query on insert which looks like this,
INSERT INTO TEMP( I1,I2)
SELECT TI1 FROM CLIENT1
WHERE R_CD ='PR' OR 'SR',
SELECT TI2 FROM CLIENT2
WHERE R_CD = 'MN' OR 'OP
There are two tables where the source data is coming from and inserted into TEMP table. I find this query to be inefficient. Anybody who can help me writing a good one?? Thanks.

A possible solution,
INSERT INTO TEMP( I1,I2)
SELECT C1.TI1, C2.TI2
FROM CLIENT1 C1, CLIENT2 C2
WHERE (C1.R_CD = 'PR' OR C1.R_CD ='SR') AND
(C2.R_CD = 'MN' OR C2.R_CD = 'OP')
null

I have a trigger on A, which inserts the DML records into B. (Table A and B structure is the almost the same,
                                   where table B will have one extra column exp_dt)
NOw Table B can have records with same P_S_C and A_C columns and exp_dt will capture the history.
for example: from the above sample data, let us take first two records..
P_S_C     A_C     P     EXP_DT
21698     13921     1     5/29/2009 3:15:41 PM     --- Record 1
21698     13921     1     5/29/2009 3:54:57 PM     --- Record 2
from this..
Note: 1. Table A and Table C can be joined using A.P_S_C and C.R_C to get the start_date.
2. PN# comes from table D. It contains numbers for the resp. weeks.
3. PN#_EFF_DATE is the previous immediate previous date for that record in history table (Table B).
I wanted the data like..
---- this is for the second record in the above..
PN#_EXP_DATE PN# PN#_EFF_DATE PN#
5/29/2009 3:54:57 PM     214 5/29/2009 3:15:41 PM     214
---- this is for the first record in the above..
PN#_EXP_DATE PN# PN#_EFF_DATE PN#
5/29/2009 3:54:41 PM     214 ( for this we should query the table C to get the
                    start_date, for this combinatation of P_S_C and A_C in table B
                         where B.P_S_C = C.A_C
                         and that value should be the EFF_DT for this record)
Please help me with this....
Thanks in advance..

Hi All,
select d.P# as "PN#_EXP_DATE", exp_date
from daily_prd d, cbs1_assoc_hist b
where to_char(d.day_date,'MM/DD/YYYY') = to_char(b.exp_date,'MM/DD/YYYY')
and d.period_type = 'TIMEREPORT';
This above query gives the output as follows:
pn#_exp_date exp_date
214     5/29/2009 3:15:40 PM
214     5/29/2009 3:15:41 PM

I got the pn#_exp_date from the Table 'D', for the given exp_date from Table B.
My question is again....
CASE - 1
from the given records above, I need to look for exp_date for the given same P_S_C and A_C.
in this case we can take the example...
P_S_C     A_C PLACE EXP_DATE
21698          3217          3     5/29/2009 3:15:40 PM
21698          3217          3     5/29/2009 3:54:57 PM
In this case, the
pn#_exp_date exp_date     pn#_eff_date eff_date
214     5/29/2009 3:15:57 PM     < PN# corresponding to the     5/29/2009 3:15:40 PM
                    eff_date .>
                    <Basically the eff_date is
                    nothing but the exp_date only.
                    we should take the immediate before one.
In this case, our eff_date is '5/29/2009 3:15:40 PM'.
but how to get this.
CASE - 2
from the above sample data, consider this
P_S_C     A_C PLACE EXP_DATE
21698     1716656     4     5/29/2009 3:15:41 PM
In this case, there is only one record for the P_S_C and A_C combination.
The expected result :
pn#_exp_date exp_date               pn#_eff_date eff_date
214     5/29/2009 3:15:41 PM     < PN# corresponding to the     5/29/2009 3:15:40 PM
                    eff_date .>
               <Basically the eff_date is
               nothing but the exp_date only.
                    we should take the immediate before one.
In this case to get the eff_date, we should query the Table 'C', to get the eff_date, which is START_DT column in this table.
for this join B.P_S_C and C.R_C.
Hope I am clear now..
Thanks in advance.....

Help in Tuning this Query

Hi,
I have a query in my proj where the same table is looked up twice in the same query.
Can anybody suggest in improving the performance of this query?
select * from table1 a1 where (a1.column1, a1.column2, a1.column3, a1.column4, a1.column5, a1.column6, a1.column7, a1.column8, a1.column9,
a1.column10) in ( select a2.column1, a2.column2, a2.column3, a2.column4, a2.column5, a2.column6, a2.column7, a2.column8, a2.column9,
a2.column10 from table1 a2 where column20 = '<condn>')
The table1 used here is same in outer query as well as the sub query. this is a example of what we use here, and the table1 contains 30 million rows. Though, creating index with 10 columns can be a option, we already have a unique index with 11 columns(which includes 10 from this query) and will that be helpful in anyway? or the same existing index can be forced?
Thanks a lot for ur time

Depending on the selectivity of column20 I am not sure Index is the best way to go. It might perform better with two full scans and a hash-join.
Anyway, I do prefer the syntax:
select /*+ leading(a2) */ a1.*
from table1 a1, table1 a2
where a2.column20 = '<condn>'
and a1.column1 = a2.column1
and a1.column2 = a2.column2
and a1.column3 = a2.column3
and a1.column4 = a2.column4
and a1.column5 = a2.column5
and a1.column6 = a2.column6
and a1.column7 = a2.column7
and a1.column8 = a2.column8
and a1.column9 = a2.column9
and a1.column10 = a2.column10;I've added a leading hint to tell oracle that the start table is a2. Might be useless.
Ensure your stats are up to date. You might need histograms here if your column20 is skewed.
Hope this helps,
François

And while writing query or any example so use the 6 digit before and after your query or example to keep the formatting in orignal format. Otherwise it becomes hard to read.
