(WRT54G) I need to set it up so that I get the same IP all the time for 1 computer on my network.

I have 4 computer I have linked to the WRT54G. 2 2 with network cables and wireless. One of these computers I use as a server and I would get the same IP address to the server all the time. As 192.168.1.150. Now it depends on when I turn on my computer what IP they get. Is there a way to get a static IP address?

IOM sql Query to get the status of the failed task
Hello world

We have an obligation as we need to get the status of a particular task (say Create User in OID - Completed\Rejected status resource) for the particular user. We are able to get the status of the provisioed of resources to the user but not the status of the special mission which is trigerred for the user.can someone put some light on it. We must have the SQL query to do this.

Thanks in advance.

Kind regards

Need help with query to get days of work there are using the calendar BOM

RDBMS: 10.2.0.4.0
Oracle Applications: 11.5.10.2

I try to use the BOM existing in the EBS to calculate working days calendar, there is a report that I am train. The BOM calendar presents the working days and non-working with the weekend days and holidays listed as non-working days. The following query gives correct results, but I'm looking for two different ways to do the same without "the union. I have nothing against the "unions", but I feel that I'm missing a more elegant to get there way. The query will in Discoverer Plus 10.1.2.3, so using a statement 'By' is not supported.

sample data

calendar_code                calendar_date                 seq_num                     
SAC-WRKDAY                   12/3/2010                     1817
SAC-WRKDAY                   12/4/2010

Hello

Of course, you should be able to combine these queries, something like this:

select calendar_code
     , calendar_date
     , seq_num
     , sum ( CASE
           WHEN  bcd.seq_num IS NULL
           THEN  0
           WHEN  bcd.calendar_date < TRUNC (SYSDATE)
           THEN  1
           ELSE  -1
          END
        ) over ( partition by  bcd.calendar_code
              ,            SIGN (SYSDATE - bcd.calendar_date)
              order by        ABS  (SYSDATE - bcd.calendar_date)
            ) workdays_ago
from   bom.bom_calendar_dates bcd
where  calendar_code = 'SAC-WRKDAY'
and    trunc(bcd.calendar_date) < trunc(sysdate)

If you do not want to display some CREATE TABLE and INSERT statements for the sample data, and then I could test it.

Good thinking!
When the two branches of the UNION query the same table, there is usually a more effective way: something that only requires a pass through the table.

How to write a simple select query to get the data of the table as an XML.
How to write a simple select query to get the data of the table as an XML. In the query, I'm just adding items below which i need be there in the XML document
```
select '<test_tag>'||EMP_NAME||'</test_tag>','<date>'||sysdate||'</date>' 
from temp_table where id_num BETWEEN 1 AND 10;
```
I have need to add the root tag as well in the beginning and the end of < root > < / root > this xml file. Please advice if this is possible with the select query
without using XMLGEN, XMLQUERY or any other packages built and function?
I need to URL escapes with the UTF-8 code points that we have already achieved using the utl_http package. Please help how to do that without using the utl_http package.

What is wrong with him?

At present, the only way I can think of to avoid a call to UTL_HTTP. SET_BODY_CHARSET is to write your own little wrapper.
In this way, you can specify the Boolean parameter or omit it if you choose to use named parameters:
```
SQL> create or replace function my_url_escape (url in varchar2)
  2  return varchar2
  3  deterministic
  4  is
  5  begin
  6   return utl_url.escape(url, false, 'AL32UTF8');
  7  end;
  8  /

Function created

SQL> select my_url_escape('http://some.uri.com/param?lang=fr&text=contrôle') from dual;

MY_URL_ESCAPE('HTTP://SOME.URI

Query to get the data of the column and the metadata in the same set of results.
Is it possible to build a query to get the values of the columns in a table and also be able to get some metadata (data type, data_length, data_precision, data_scale) for columns in the same set of results.
If I use a join, have a common value to join on the two tables?

you use a cross join, not requiring common values.
```
create table T (n number, d date, v varchar2(30));
insert into T values (1,sysdate,'ABC');
commit;

select C.column_name, c.data_type, c.data_length,
case c.column_id
 when 1 then to_char(T.N)
 when 2 then to_char(T.D)
 when 3 then T.V
end VALUE
from USER_TAB_COLUMNS C, T
where C.table_name='T'
order by c.column_id;
```

Query with almost the same query as a subquery, can it be optimized?

I have a query using almost a duplicate of itself (table 1) as a subquery, and I wonder if it can be rewritten better, like she just doesn't seem the right way to do it, but everything I try I can't get the same number of lines back.

If anyone can see a better way, it would be a great help.

Thank you very much

Surely it is not the best way to write it as you use the same table twice and restrictions?

Published by: Scott Hillier on March 16, 2010 15:11

It looks like you want all the lines of the siblings who do not personally meet the restriction on trn_fnd_code. You can use analytical functions;

Tuning sql of a product to the seller without changing the sql statement
Hello

We have a product of the provider that generates the SQL statement. For a query, we get the answer in 15 seconds. But users are asking if we can bring it back to 5 seconds. Limitation is the query can not be changed. He used about 10 to 12 tables and bit complex query.

What kind of options could be evaluated if we are to improve the performance of a query (not sure if she could never be reduced to 5 seconds)
without making any change to the query.
