This type of possible to query (select with based correspondence stop lines)

I'm trying to write a SQL query and suspect it is impossible. Or at least, I cannot not mentally grasp, despite various stabs with subqueries. I simplified it by changing the metaphor here a bit.

Let's say I have a truck in a city (say, Chicago). There are several roads leading out of town, with routes, we will label according to the compass points (N, NE, SW, etc.) Each truck can carry only one shipment. It starts along his route, and as soon as it comes to a city in need of his expedition, he stops.

Yes, one cooked, but it is similar to my problem.

Here is a table:

TABLE: truck_routes
scenario (integer - possible scenarios)
Route (NE, SW, etc - 8 cardinal points)
destination (towns along this road)
sequence_number (order in which should go to the cities)

So if I have a truck in Chicago, I can tell

SELECT the road, sequence_number, destination
OF truck_routes
Scenario WHERE = 10 (or other)
ORDER BY road_out, sequence_number;

And I would get a report like this:

SE 1 Gary
SE 2 Valparaiso
SE 3 Plymouth
SE 4 Warsaw
NO 1 Michigan City
2 Kalamazoo
ONLY 3 Grand Rapids
DO 4 Cadillac
ONLY 5 Traverse City

So far so good. I have another table with a list of cities that must be the subject of the expedition:

TABLE: cities
scenario (integer - possible scenarios)
Route (NE, SW, etc - 8 cardinal points)
destination (same keys as in truck_routes)

for example:

10 Valparaiso SE
Warsaw SE 10
10 DON'T Cadillac
10 DON'T cross City

Now... the delicate part... How do rewrite the query above so that after a truck hit a city in need of a shipment (in this case), it stops? In other words, I want a report (for all channels) of which cities the truck stops to- and such that mentioned, it stops at the first one she performed. I don't want to see lines beyond that. If the report is as follows:

SE 1 Gary
SE 2 Valparaiso
NO 1 Michigan City
2 Kalamazoo
ONLY 3 Grand Rapids
DO 4 Cadillac

Gary arises because it does not require a delivery. Valparaiso (road SE, sequence_number 2) arises because he takes delivery. The rest of the Southeast route does not appear. Same thing for the road DON'T.

There are scenarios where I actually want to stop at the city just before the place of delivery, etc. and of course in the real world, that it's more complicated, but I think that if I could get this working model I could flesh out in a real-world application.

Certainly I can code something in PL/SQL for this do, or do it in the logic of the application - but I wonder if there is a way to do it in a single SQL statement? I suspect there is something that could be built with subqueries and sorting, but... I can't reach him quite ;-)

query selection with numbers
I have something on my site, which select bands with the letter that is clicked

< name cfquery = 'results' datasource = '#APPLICATION. DataSource #">"
SELECT *.
Of artist_art
WHERE the bandname_art as '#url.firstletter#% '.
< / cfquery >
http://www.musicexplained.co.uk/index.cfm
the thing is, im trying to consolidate all the bands that start with a number together and am unsure of the symbol which refers to "all numbers" in coldfusion...
Searched everywhere, but this place seems to be the only place with responses from lately, so...

Thank you

you spend a specific number in the URL? If you are, this is the same code that you (WHERE bandname_art LIKE ' % #url.firstLetter # ').

If you use the sign # and want to get the strips that begin with any number from 0 to 9, check if access supports regex. in SQL Server, the following would work:

WHERE bandname_art LIKE ' [0-9] %'

can't vouch for access tho.

EDIT: If Access doesn't support it, the worse your query will look:

WHERE bandname_art LIKE ' 0% ' GOLD bandname_art AS 1% ' OR bandname_art LIKE 2% '...

-or-

WHERE left (bandname_art, 1) with ('0', '1', '2', '3', '4', '5' ', 6',' 7 ', ' 8',' 9 ', ' 0')

(the latter is where I think that Dan was trying to direct you towards)

What happened to the ability to hide the "mobile dash" (CTRL/CMD (H) in Photoshop? I can't see the edges of my selection with the mobile dotted lines in the way!

I used Photoshop since version 2.5 when it came to 16 disks. In all versions I've bought over the years (many) up to CS3, I've always been able to use CTRL + H (Windows) or CMD + H (Mac) to hide the "mobile dash" edge of the selection. This is extremely useful when doing all sorts of adjustments where the outline of the selection must be considered while "fiddling with the buttons" (so to speak). Without being able to hide the limits of selection ("mobile dash"), I often have to get a better idea, cancel the selection, get disgusted that the edge is not what I want, then have to cancel, select new, try again... over and over again. It is a SIMPLE feature, but the lack of it, driving me crazy. HELP, I tried, but it doesn't have the height of the promise. If there is a way to hide the dotted moving line, where is the menu item, and what the shortcut?

You can assign Ctrl/Cmd-H to hide the edges of the selection (Edit > keyboard shortcuts) only, if you want to hide everything, but you will be notified if any other function has the shortcut.

This is how a SELECT query fails with ORA-1555 occur?

11 GR 2/RHEL 6.2
I would like to know exactly how a SQL fails with error ORA-1555.
Please take a look at the following simple example.
INVENTORY_DETAIL is a table that stores information about items in a store.
For this DB UNDO_RETENTION is set to 3 600 (1 hour) and TUNED_UNDO_RETENTION Meanwhile 5400 (1.5 hours)
At 15:00, there's 12 Logitek involved in inventory.
ITEM_ID NOM_ELEMENT STOCK_LEFT
--------- -------------------- ----------
8432 LOGITEK 12 SPEAKER
At 15:00 Session1, starts a SELECT large with several tables joins query. Something like
Select id.item_id, id.item_name, su.supplier_price, su.supplier_code
Su.batch_code...
of INVENTORY_DETAIL id join in-house suppliers knew on (id.supplier_id = su.supplier_id)
...
..
03:02, Session1 reads the block that stores the line with item_id = 8432 and learns that he has 12 Logitek left speakers.
15:10, Session2 delivers the next UPDATE and he agrees immediately.
Update inventory_detail set stock_left = 7 where item_id = 8432;
commit;
The UNDO data for Session2 transaction are stored in the measure of cancellation remaining, and the UNDO data gets debusquees at 04:40 when the TUNED_UNDO_RETENTION of 1.5 hours is crossed at 16:40.
Because of the bad of e/s, query SELECT of Session1 manages to retrieve all the records only from 17:00.
But session1 notice this line with item_id = 8432 changed. Now, there's only 7 Logitek speakers which is inconsistent with what he learned at 15:02 (who was then at 12). Because of this incompatibility SO not able to recover data UNDO on this gap, ORA-1555 is thrown. My assumptions are good?
3:10PM 4:10PM 4:40PM 5:00PM
|===================================|-------------------------------|-----------------------------|
UNDO_RETENTION = 1 HR retention Undo Tuned = 1.5 h finishes of request for enforcement

Martin, you asked, "are the correct on the circumstances that led to ORA-1555 my explanations? The answer is no. Oracle does not notice at the end of the query that changed a line he read. Instead, each read line is at the same point in time. When Oracle sees that a row has changed Oracle reads the UNDO segments to find the version of the data corresponding to the query start time. If these data cannot be found the ORA-01555 error is raised.

Windows will not honor "always use the selected program to open this type of file."

When I try to open a file *.img using 'open with... '. "I get a window of"Leader Type Helper"asking what software I want to use. I have check "open this file using a software program (sic) that (sic) is already installed." This very unnecessarily opens another dialog box titled 'open with' * Sub * the files already browser window fill the screen while I'm not yet aware that the box is here. Having managed to find, I choose "7-Zip File Manager" and click on the box always saying "use the selected program to open this type of file", and then click OK. This opens the file using the selected program, as you wish.

However next time I try to open a *.img file, I again get the window "Help file of Type" and must go through the whole process again. (By double-clicking on the file shows "Windows Disc Image Burner".) Why don't Windows 'always use the selected program' like I asked? Windows is aware that I have chosen before, because it is considered to be the only 'recommended program' in the 'Open with' dialog box Thanks for any help!

I accidentally click "always use the selected program to open this type of file" on the srt file. How to make it undefault and again the icon to icon file empty white?

You can do this via a registry change, but it is more appropriate for a typical user to simply use the system restore:

Ever wished that you can go back in time following a bad fall? With Windows, you can.

Installation sometimes a driver or a program can make Windows run slowly or erratically. System Restore can return programs and system files from your PC to a time where everything worked, potentially prevent hours of troubleshooting of headaches. This will not affect your documents, images or other data.

In Windows 7, you can create system restore points more and see exactly what files will be deleted or added when your PC is restored. For more information, see create a restore point.

For more protection, use the restore system backup and restore, which is designed to help save email, photos, documents and other personal files.
To use the system restore
Before you start the system restore, save open files and close all programs. System Restore will restart your PC.

Open system restore by clicking the start . In the search box, type restore the system and then, in the list of results, click on system restore. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

Follow the steps in the wizard to select a restore point and restore your computer.

Regarding the "bookmarks", those that are normally visible by the user and will be not viewable unless the name of the bookmark appears also as text within the topic.
