Hi all, if I have a table like above to demonstrate the
folders and item relationship. This structure allows the user to
create unlimited folders and items.
Now I would like to use one query to find out the tree
structure of this table, how could I do the query.
Any help on this will be highly appreciated!
Thanks,

Can I do this?

Hi Andrzej,
please check out this thread: Set parameters values depending on other parameters
I had a discussion about query results as input for another query in there.
For creating a workbook, just click on the save button after you ran your query in the bex.

How to use statement "search" to find out the asterisk in a string?

Hi Guys,
   I encouter this question:I need to use "search" statement to find out the asterisk or the underscore in one string,you know these two symbols are wildcards. I don't know how to use statement "search" to find them??
   could you please give me some help!!
Thanks a lot,Villy.Lv
Edited by: Villy Lv on Sep 26, 2010 6:50 AM

Hi,
You cant usesearch statement, rather did you try with CS using IF condition? even you can go with loop statement too.
DATA STRING TYPE STRING.
DATA C TYPE C.
DATA LEN TYPE I VALUE 0.
DATA I TYPE I VALUE 0.
LEN = STRLEN(STRING).
LOOP LEN > I
     C = STRING+I.
     IF(C == '*' OR C == '_').
     ENDIF.
     I = I + 1.
ENDLOOP.
This way also you can use.
Hope this may help you.
Regards!

How to use one query against multiple table and recieve one report?

I have duplicate tables, (except for their names of course) with commodities prices. They have the same column headings, but the data is different of course. I have a query that gives me a certain piece of information I am looking for but now I need to run this query against every table. I will do this every day as well, to see if the buying criteria is met. There are alot of tables though (256). Is there a way to say run query in all tables and return the results in one place? Thanks for your help.

hey
a. the all 256 tables whuld be one big partitoned table
b. you can use all_tables in order to write a select that will write the report for you:
SQL> set head off
SQL> select 'select * from (' from dual
2 union all
3 select 'select count(*) from ' || table_name || ' union all ' from a
4 where table_name like 'DB%' AND ROWNUM <= 3
5 union all
6 select ')' from dual;
select * from (
select count(*) from DBMS_LOCK_ALLOCATED union all
select count(*) from DBMS_ALERT_INFO union all
select count(*) from DBMS_UPG_LOG$ union all
remove the last 'union all', and tun the generated quary -
SQL> set head on
SQL> select * from (
2 select count(*) from DBMS_LOCK_ALLOCATED union all
3 select count(*) from DBMS_ALERT_INFO union all
4 select count(*) from DBMS_UPG_LOG$
5 );
COUNT(*)
         0
         0

Networking question; How to use MAC address to find out IP address.

Hi there,
I want to discover the IP address of an attached device (Netgear switch) on my network. I know it's MAC address – can I use this to get the IP address?
Thanks in advance

Short for Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium. Consequently, each different type of network medium requires a different MAC layer.
On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC)
I have a feeling you might have the term MAC Address confused
Depending on the device you are using it may be that you can type in 192.168.1.1 and hit return key, and it will give you the Router Utility and this can give you the assigned IP Addresss to external devices, if the router is used.

How to use one Account dimension for multiple account structures

We are implementing a HFM application to replace two general ledger applications, one being Corporate and the other a new subsidiary. We need to maintain both of the chart of accounts and their unique rollup structures. We are facing the difficulty in attempting to combine the two chart of accounts into one HFM Account Dimension because a few of the subsidiary accounts have the same account numbers but they are meant different things.
Question:
How can we set up two distinct account structures in HFM and also have the subsidiary accounts rolled into the Corporate accounts for consolidation reporting?
Appreciate your help.

Hope this help.

Need query to find out the sum till a period

Hi,
I need to write one query to find out the cumulative sum of raw_cost of table pa_budget_lines till the specified period, I tried to do this by analytical function, but that is not working in Report 10g. Can anybody help me in this.
Thanks

not familiar with report but could you do something like this
with t as
select 1 grp, 10 * level the_cost, add_months (sysdate, level) effective_dt from dual connect by level < 11 union all
select 2 grp, 5 * level the_cost, add_months (sysdate, level) effective_dt from dual connect by level < 11
input as
( select null grp, null the_cost, null running_total, v_eff_dt effective_dt   from dual)
select * from(
select t.grp, t.the_cost, sum(t.the_cost) over (partition by t.grp order by t.effective_dt) running_total, t.effective_dt,
       lead(t.effective_dt) over (partition by t.grp order by t.effective_dt) next_effective_dt,
       input.effective_dt inp_eff_dt
from t, input
where inp_eff_dt between effective_dt and next_effective_dtv_eff_dt would be the input date you are interested in

Query to find out the time used by an user for an application

Hello All,
I want to know the query to find out the whole time used by the user for an application. Please view the below data
Employee:
SNO EMP_ID EMP_NAME EMP_DATE LOGIN_TIME LOGOUT_TIME
1 10 Visu 21-Nov-2010 06:30:00 07:30:00
2 10 Visu 21-Nov-2010 06:40:00 07:20:00
3 10 Visu 21-Nov-2010 06:50:00 07:50:00
4 10 Visu 21-Nov-2010 07:30:00 08:30:00
5 10 Visu 21-Nov-2010 09:30:00 10:30:00
By checking the above data we can say that the total time Visu used the application is
8.30 - 6.30 (From 1,2,3,4 records) = 2hrs
10.30 - 9.30 (Based on 5th rec) = 1hr
So the total time Visu used the application would be 3 hrs = 180 mins.
Could you please help me in getting the result from that data using a query?

Query to find out whether a table is sub-partitoned , composite type one

Could you please let me know the query to find out whether a paritioned table
is
1). composite paritioned one.
2). sub-paritioned one.
I find that there are 2 cols in all_tab_partitions view, which lets me know
1). COMPOSITE VARCHAR2(3)
To find composite paritioned one or not.
2). SUBPARTITION_COUNT NUMBER
To find whether a table is sub-paritioned one or not.
Any light on the above topic is highly appreciated.

So it seems you've found the answer yourself?
with »user_tab_partitions« and »user_tab_subpartitons« you'll get all the neccessary information you are looking for.

thanks for replying guys. But the thing is i am using dynamic sql execute immediate in my package, so i want those tables also and the schema name.
thanks,
ortonThis is not possible. The best you could do is to have a good guess.
Or how would you parse some dynamic statement as this:
   v_suffix := 'loyees';
   v_sql := 'Select count(*) from (select ''nonsense'' col1 from emp'||v_suffix||') where col1 = ''Y'''';
   execute_immediate(v_sql);
...What is the table name? How do you want to parse that?
Better rewrite all dynamic SQL statements into non dynamic ones. Or do the source control logic for those dynamic parts in an extra module. For example implement your own dependency table and force every developer to add there all dynamic parts.

Query to find out which process consuming more cpu?

Hi All,
some one please tell me the query to find out which process is consuming more
cpu resources?
Thanks and Regards

Use V$SESSTAT to determine which sessions are using most CPU, and investigate what SQL these users/sessions are executing:
SQL> select ss.sid, se.command, ss.value CPU, se.username, se.program
from v$sesstat ss, v$session se
where ss.statistic# in
(select statistic#
from v$statname
where name = 'CPU used by this session')
and se.sid=ss.sid
order by ss.value desc;
