[8i] not to simplify this query?
In my application, I need to pick up three possible prices for each part number in an array.The three possible prices that I need to recover are:
(1) the price paid on the order more recently closed,
(2) the price mentioned on the first pending order, and
(3) the price on the furthest on pending order.
However, there is a complication in that. Orders include the part number, but may also include a prefix of 4 characters (always the same) on a reference number which should be treated the same as the reference database. For example, "DSB-part1" should be considered "part1", "DSB-part2" should be regarded as 'part 2', etc.
In addition, it is quite possible for several orders expected or closed on the same day, and I want to only return the price of one of these lines for each of the 3 methods of pricing.
(Technically, there is another level of complication to this, but if I have problems with it later, I'll create a new job for him...)

Whenever you want to have a WHERE clause only applies to certain columns, think about a pivot and expression BOX.
Is there a reason to have raw triling part_no or ord_part_no?

After this announcement, I saw that Max had posted essentially the same query.
In general, where the solution of Max seems more simple, I like her way better.
The only possible exception is tested for "OP" at the derivation of the values first_open and last_open. If none of the lines to an ord_stat part_no = "OP", solution of Max will be used a the lines with another ord_stat. That does not occur in the sample data, and I don't know if this is still possible in your application, but if this is the case, I don't know this isn't what you want.

Or can anyone simplify this query?Hello
in this case, you need to use is analytical functions:
that is to say:

Why between date is not return data for this query?
Hello
I have a table with this structure and I write this query to retrieve a few lines based on certain conditions, but this query returns no data. Can you please tell why?
ID DT 003 11/8/2011 002 10/8/2011 001 9/8/2011And the execution of the query:
Published by: starting August 13, 2011 07:10SELECT * FROM TABLE_NAME WHERE DT BETWEEN TO_DATE('08/08/2011','dd/mm/yyyy') AND TO_DATE('12/08/2011','dd/mm/yyyy');
>
>
But what is the problem with that, why this date does not match when I'm providing the date format?
What part don't you understand? You have not used TO_DATE when inserting data and default date format is dd/mm/yyyy, right? Same default date format is used if you are running:
SELECT * FROM TABLE_NAME
Original of your post States select returns above:
ID DT 003 11/8/2011 002 10/8/2011 001 9/8/2011So the dates that you inserted are November 8, 2011, October 8, 2011-September 8, 2011. TO_DATE('08/08/2011','dd/mm/yyyy') is now August 8, 2011 and TO_DATE('12/08/2011','dd/mm/yyyy') is August 12, 2011. Then of course:
SELECT * FROM TABLE_NAME WHERE DT BETWEEN TO_DATE('08/08/2011','dd/mm/yyyy') AND TO_DATE('12/08/2011','dd/mm/yyyy').
will return all the lines. Bottome line - never write code that uses the implicit conversions date since your code becomes dependent on the NLS client settings and maybe working for a client and fail or produce erroneous results for other customers.

create table contact (phone number); insert into phone values (1234567890); insert into phone values (1234567891); insert into phone values (1234567892); insert into phone values (1234567893); insert into phone values (1234567894); insert into phone values (1234567892);And then run your selection.

Table1 a record 3Million and table 2 has 1 million records.
I used gather stats before you run this query and 'Full' trick, even in this case, he is running for 45 minutes.
Please suggest the best solution to optimize this query.
Thanks in advance.
Remove the tips.
No need for the separate.
Get the diff by ceil (abs(t2.m_date-t1.m_date)) and the filter for that where value_diff<>
Assing the statement ".. MATCHED" lately in the update clause.
Maybe give exactly to your needs with a small example may be the query may be getting more simplified or not what you want it to do.

I have been using a trading on XP very good software, but since installing this software on my Windows Vista Home Premium (Svc Pk 2), I get the dreaded "MS Html Help is not installed on this PC" whenever I am trying to view the 'Help' file from the software owner menu.
One of the messages on this forum (http://social.answers.microsoft.com/Forums/en-US/vistaprograms/thread/781b8c60-41cf-482f-bcd9-d20455f9b190) said a solution "the solution is to change the call to be directly to the Windows API htmlHelp." If this is the case how can I do to run the software to do this.
Appreciate your help guys :-)

We are running Windows 7 Enterprise 64-bit (using VMware View 6.1) virtual work stations and the connection of users to a printer Xerox 4 Type driver/file being hosted on a Windows R2 server in 2012. The driver on the server is listed as "Xerox WorkCentre 7970 V4 PCL6" and when the user of Windows 7 connects the driver appears as "Microsoft enhanced driver compatibility point and print. In the "Print Management" client Win7, it appears as the 6.3.9600.17415 version
The Printer works fine during their Windows session, they disconnect you and when they connect in the print queue is still there but when you right click and go to "Printer properties", he throws the following error
"The printer driver ' improved point and print compatibility Microsoft driver" is not installed on this computer. " Some printer properties will be unavailable, unless you install the printer driver. You want to install the driver now? »
Deleting the queue and then add it again resolves the problem for Windows session, you're.
Note: we use Persona management of VMware to save data from the user profile of the disconnections from the virtual offices are non-persistent. I've been able to reproduce this in Windows 7 using a virtual office, I can't reproduce it on my physical Windows 7 machine.
We get around this by using Group Policy and a vbs script to delete the queue on logoff, then another script to add back on logon, but it's just a band-aid.
In addition, a Type 3 driver works fine in all of disconnections but we need the Type 4 driver in this case.
