  • Nested query to find details in table B for maximum value in table A

    - by jpatokal
    I've got a huge bunch of flights travelling between airports. Each airport has an ID and (x,y) coordinates. For a given list of flights, I want to find the northernmost (highest x) airport visited. Here's the query I'm currently using: SELECT name,iata,icao,apid,x,y FROM airports WHERE y=(SELECT MAX(y) FROM airports AS a , flights AS f WHERE (f.src_apid=a.apid OR f.dst_apid=a.apid) ) This works beautifully and reasonably fast as long as y is unique, but fails once it isn't. What I'd want to do instead is find the MAX(y) in the subquery, but return the unique apid for the airport with the highest y. Any suggestions?

  • Creating new table entry when updating another entry of another table - Ruby on Rails

    - by Michaël
    Hi, I have written this code in my "show" view of estimates and I want that, when submitting (update), it creates a new repairs (Repair.new(???)) with some parameters. I don't know where to write the "new repairs" code, in this view or the controller (in update part). I need that the Repair is created one time, not each time the @estimate is updated. <% form_for @estimate, :url => {:controller => "estimates", :action => "update"} do |f| %> <%= f.error_messages %> <select id="estimate_accept" name="estimate[accept]"> <option value="1" selected="selected">accept</option> <option value="2">refuse</option> </select> <%= f.submit "Update" %> <% end %> Thank you for your help, I hope my explanations are clear!

  • Select 2 Rows from Table when COUNT of another table

    - by Marcus
    Here is the code that I currently have: SELECT `A`.* FROM `A` LEFT JOIN `B` ON `A`.`A_id` = `B`.`value_1` WHERE `B`.`value_2` IS NULL AND `B`.`userid` IS NULL ORDER BY RAND() LIMIT 2 What it currently is supposed to do is select 2 rows from A when the 2 rows A_id being selected are not in value_1 or value_2 in B. And the rows in B are specific to individual users with userid. What I need to do is make it also so that also checks if there are already N rows in B matching a A_id (either in value_1, or value_2) and userid, and if there are more than N rows, it doesn't select the A row.

    - by owca
    In my database I have a form for searching products (fields : id, name, manufacturer_id[set to display manufacturer's name], category_id, price). I would like to have the ability of adding manufacturers through this form. So I've created vba script but it does not work. Still when I enter new name it gives me prompt to "Select element from the list". What am I doing wrong ? Private Sub manufacturer_id_NotInTheList(NewData As String, Response As Integer) Dim strSQL As String, strInfo As String strInfo = "Manufacturer " & NewData & " is not on the list." & vbCrLf & "Add?" If MsgBox(strInfo, vbYesNo + vbQuestion, "Element not on the list") = vbYes Then strSQL = "INSERT INTO manufacturer (name, country, id_distributor) VALUES ('" & NewData & "','Undefined', '0');" DoCmd.SetWarnings (False) DoCmd.RunSQL strSQL Response = acDataErrAdded Else Response = acDataErrContinue NewData = "" Me.manufacturer_id.Text = "" End If End Sub

  • Multisite Enabling a Table

    - by Joe Fitzgibbons
    I am creating a table (table A) that will have a number of columns(of course) and there will be another table (table B) that holds metadata associated to rows in table A. I am working with a multi site implementation that has one database for the whole shabang. Rows in table A could belong to any number of sites but must belong to at least one. The problem I have is I am not sure what the best practice is for defining what site each row in table A belongs to. I want performance and scalability. There is no finite number of sites going forward. Rows in table A could belong to any number of sites in the future. Right now there are only 3. My initial thoughts are to have a primary site ID in Table A and then metadata in table B will have rows defining additional sites as needed. Another thought is to have a column in Table A for each site and it is a boolean as to wether it belongs to that site. Lastly I have thought about having another table to map rows in Table A to each site. What is the best way to associate rows in a table with any number of sites with performance and scalability in mind?

  • Tagged: 5 things SQL Server should drop

    - by AaronBertrand
    I was tagged by Paul Randal ( blog | twitter ) last night in his latest blog post, entitled, " What 5 things should SQL Server get rid of? " His top 5 pretty much coincide with my top 5, so I'll have to dig a little deeper. In no particular order: Syntax inconsistencies This isn't really a specific thing that Microsoft should get rid of, but rather an attitude and overall approach to SQL Server's long-term development. Every time they add a feature or option to SQL Server, it seems to be implemented...(read more)

  • Mysql PHP generated table: doesn't work with Tablesorter

    - by echedey lorenzo
    Hi, I found this great Tablesorter plugin for jQuery but I can't make it work with my PHP generated table. Here's the code: <script type="text/javascript"> function table() { $("#container").load("table.php?randval="+Math.random()); } $(document).ready(function() { table(); $("table").tablesorter(); }); </script> Where #container is the div where the table will be and table is the name of the table. I get the table loaded but sorting function is not working. It works if I put the table directly in html in the page.. but I don't see the point in having a static table for sorting. Any help would be very appreciated.

  • Python In-memory table

    - by nsharish
    What is the right way to forming in-memory table in python with direct lookups for rows and columns.I thought of using dict of dicts this way, class Table(dict): def __getitem__(self, key): if key not in self: self[key]={} return dict.__getitem__(self, key) table = Table() table['row1']['column1'] = 'value11' table['row1']['column2'] = 'value12' table['row2']['column1'] = 'value21' table['row2']['column2'] = 'value22' >>>table {'row1':{'column1':'value11','column2':'value12'},'row2':{'column1':'value21','column2':'value22'}} I had difficulty in looking up for values in columns. >>>'row1' in table True >>>'value11' in table['row1'].values() True Now how do I do lookup if 'column1' has 'value11' Is this method of forming tables wrong?Is there a better way to implement such tables with easier lookups?.Thanks

  • Clone DB table row through MVC in SQL Server

    - by sslepian
    Is there a simple solution for duplicating table rows in SQL Server as well as all table rows with foreign keys pointing to the cloned table row? I've got a "master" table and a bunch of "child" tables which have a foreign key into the ID of the master table. I need to not only create a perfect copy of the master table, but clone each and every child table referencing the master table. Is there a simpler way to do this than creating a new row in the master table, copying in the information from the row to be cloned, then going through each child table and doing the same with each row pointing to the cloned row in the master table? I'm using a SQL Server 2005 Database accessed through C# ASP.net MVC 1.0.

  • Fixing corrupt files or corrupt file table on a USB drive?

    - by Kelsey
    I was doing a virus scan on an external USB drive while copying data over to it. While AVG was scanning my system got locked up I think due to the USB drive running out of space and it required a reboot. Since that time all data on the external drive is no longer accessible. I can see all the files in the root and directories but I cannot browse into any of them as Windows 7 gives an error stating they are corrupt. I think the file table or whatever it uses to store the index of what exists on the drive has been corrupted since it still shows the the drive as being almost full but everything I do a properties check on says it is 0 bytes. Does anyone know how to 'unlock' or recover this data? Is there a way to rebuild the file table somehow? Luckily I can recover this data from other sources as a last resort but I would like to fix this if possible. Any help would be appreciated. Thanks.

  • refile a table row in emacs org mode

    - by justinhj
    I have a template for org-capture more that looks like: ("w" "Websites" table-line (file+olp "~/Dropbox/mystuff.org" "Websites" "To view") "| %c | %^{Description}") which adds a table line to a table of web pages I want to view when I do org-capture and press 'w'. This works just fine. The I wanted to refile the To View table line to a table with the headline "Viewed" using this (setq org-refile-targets '(("mystuff.org" :regexp . "Viewed") But what org mode does is takes the whole table rather than the url on the row I want to refile, and puts the To View table under the Viewed table. Obviously not what I want. Is there a way to do what I want?

  • How to recover a MySQL InnoDB table?

    - by Kau-Boy
    When I try to launch the Plesk administration page of you server I get the following error: ERROR: PleskMainDBException MySQL query failed: MySQL server has gone away The MySQL Server is working well. Although it seems that the plesk database is somehow corrupt and any action on this database results in a restart of the mysql process, so even queries to other databases on the same MySQL server will be lost. If I try to connect to the plesk database using phpMyAdmin, I can only see the number of tables, the database had originally. But I am not able to open the tables listing. As soon as I try it, the mysql process crashes again. Trying to connect to the database using ssh works. I can even run a SELECT statement against any table an get a result. I don't know if it is an plesk error or an error of the psa database or even the MySQL server. Can you give me any tips on how to recover the plesk system. Should I try to repair the Plesk installation before. And if so, how can I do it and will all my settings get lost doing it? EDIT: Trying to dump the database, I get the following error: mysqldump: Got error: 2013: Lost connection to MySQL server during query when using LOCK TABLES EDIT: I could find out, that the table 'data_bases' is responsible for the crash of the MySQL server process. But trying to repair it using a REPAIR TABLE statement doesn't work. EDIT: I now dropped the whole database and restored it from a dump. But why I try to recover the data_bases table I get the following error: ERROR 1005 (HY000) at line 24: Can't create table './psa/data_bases.frm' (errno: 121) I am not able to create the table again. Somewhere in the MySQL system there is still some information about this table. I tested the same thing locally. If I just delete the table files and then try to create the table again I get the same error. If I drop the table through MySQL, I can create the table again afterwards. But trying to drop the table using MySQL the whole MySQL system crashed. Is there any way to solve that issue?
