• MySQL Join issue

  - by mouthpiec

  Hi, I have the following tables: --table sportactivity-- sport_activity_id, home_team_fk, away_team_fk, competition_id_fk, date, time (tuple example) - 1, 33, 41, 5, 2010-04-14, 05:40:00 --table teams-- team_id, team_name (tuple example) - 1, Algeria Now I have the following SQL statment that I use to extract Team A vs Team B SELECT sport_activity_id, T1.team_name AS TeamA, T2.team_name AS TeamB, DATE_FORMAT( DATE, '%d/%m/%Y' ) AS DATE, DATE_FORMAT( TIME, '%H:%i' ) AS TIME FROM sportactivity JOIN teams T1 ON home_team_fk = T1.team_id JOIN teams T2 ON ( away_team_fk = T2.team_id OR away_team_fk = '0' ) WHERE DATE( DATE ) >= CURDATE( ) ORDER BY DATE( DATE ) My problem is that when team B is empty, I am having irrelevant information .... it seems that it is returning all the combinations. I need a query that when team B is equal to 0, (this can occur in my scenario) I get only Team A - Team B (as 0) once.

• Is it possible for a Grails Domain to have no 'id'?

  - by firnnauriel

  Is it possible to create a table that has no 'id'? For example, this is my domain: class SnbrActVector { int nid String term double weight static mapping = { version false id generator: 'identity' } static constraints = { } } When I run this SQL statement, it fails: insert into snbr_act_vector values (5, 'term', 0.5) I checked the table and 'id' is already set to autoincrement. I'm thinking that another option is to remove the 'id' itself. Or is there another workaround for this? Please assume that it is not an option to change the givent SQL statement.

• How to write my own global lock / unlock functions for PostgreSQL

  - by rafalmag

  I have postgresql (in perlu) function getTravelTime(integer, timestamp), which tries to select data for specified ID and timestamp. If there are no data or if data is old, it downloads them from external server (downloading time ~300ms). Multiple process use this database and this function. There is an error when two process do not find data and download them and try to do an insert to travel_time table (id and timestamp pair have to be unique). I thought about locks. Locking whole table would block all processes and allow only one to proceed. I need to lock only on id and timestamp. pg_advisory_lock seems to lock only in "current session". But my processes uses their own sessions. I tried to write my own lock/unlock functions. Am I doing it right? I use active waiting, how can I omit this? Maybe there is a way to use pg_advisory_lock() as global lock? My code: CREATE TABLE travel_time_locks ( id_key integer NOT NULL, time_key timestamp without time zone NOT NULL, UNIQUE (id_key, time_key) ); ------------ -- Function: mylock(integer, timestamp) DROP FUNCTION IF EXISTS mylock(integer, timestamp) CASCADE; -- Usage: SELECT mylock(1, '2010-03-28T19:45'); -- function tries to do a global lock similar to pg_advisory_lock(key, key) CREATE OR REPLACE FUNCTION mylock(id_input integer, time_input timestamp) RETURNS void AS $BODY$ DECLARE rows int; BEGIN LOOP BEGIN -- active waiting here !!!! :( INSERT INTO travel_time_locks (id_key, time_key) VALUES (id_input, time_input); EXCEPTION WHEN unique_violation THEN CONTINUE; END; EXIT; END LOOP; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE COST 1; ------------ -- Function: myunlock(integer, timestamp) DROP FUNCTION IF EXISTS myunlock(integer, timestamp) CASCADE; -- Usage: SELECT myunlock(1, '2010-03-28T19:45'); -- function tries to do a global unlock similar to pg_advisory_unlock(key, key) CREATE OR REPLACE FUNCTION myunlock(id_input integer, time_input timestamp) RETURNS integer AS $BODY$ DECLARE BEGIN DELETE FROM ONLY travel_time_locks WHERE id_key=id_input AND time_key=time_input; RETURN 1; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE COST 1;

Any way to do it? Thanks.

• Entity Framework projections

  - by David McClelland

  We are investigating the Entity Framework to see if it will meet our particular needs. Here is the scenario I am interested in: I have a large table (let's call it VeryWideRecord) which has many columns, and it has a corresponding business object (it's also called VeryWideRecord). I would like to be able to query my database for a VeryWideRecord business object, but only have values for certain columns returned by the underlying SQL. Can I do this with the Entity Framework? I am uncertain as to whether this could be done with the Entity Framework's table splitting feature, because the application needs to be able (at runtime) to change the columns that are requested. The reason for this is that we are trying to minimize the amount of information that is going across the wire. I see how this could be done using NHibernate (example), but how can I do this with the Entity Framework?

• Select records from XML column (SQL Server 2005) based on node order

  - by jdoe

  I have a column in a SQL Server 2005 table defined as an XML column. Is there a way to select records from this table based on the order of two nodes in that column? For example, we have the following structure in our XML: <item> <latitude/> <longitude/> </item> I want to see if there are any records that have latitude/longitude in the opposite order i.e. <longitude/> then <latitude/>. I've tried some XPath expressions but with no luck.

• iPhone/Obj-C - Archiving object causes lag

  - by Dylan

  Hi I have a table view, and when I delete a cell I am removing an item from an NSMutableArray, archiving that array, and removing the cell. However, when I do this, it is causing the delete button to lag after I click it. Is there any way to fix this? // Override to support editing the table view. - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { int row = [indexPath row]; [savedGames removeObjectAtIndex:row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; //this line causing lag [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]]; } } Thanks

• Problem with altering model attributes in controller

  - by SpawnCxy

  Hi all, Today I've got a problem when I tried using following code to alter the model attribute in the controller function userlist($trigger = 1) { if($trigger == 1) { $this->User->useTable = 'betausers'; //'betausers' is completely the same structure as table 'users' } $users = $this->User->find('all'); debug($users); } And the model file is class User extends AppModel { var $name = "User"; //var $useTable = 'betausers'; function beforeFind() //only for debug { debug($this->useTable); } } The debug message in the model showed the userTable attribute had been changed to betausers.And It was supposed to show all records in table betausers.However,I still got the data in the users,which quite confused me.And I hope someone can show me some directions to solve this problem. Regards

• SQL - suppressing duplicate *adjacent* records

  - by Trevel

  I need to run a Select statement (DB2 SQL) that does not pull adjacent row duplicates based on a certain field. In specific, I am trying to find out when data changes, which is made difficult because it might change back to its original value. That is to say, I have a table that vaguely resembles: A, 5, Jan A, 12, Feb A, 12, Mar A, 12, Apr A, 9, May A, 9, Jun A, 5, Jul And I want to get the results: A, 5, Jan A, 12, Feb A, 9, May A, 5, Jul discarding adjacent duplicates but keeping the last row. The obvious: Select Letter, Number, Min(Month) from Table group by Letter, Number does not work -- it doesn't include the last row.

• Referencing outer query's tables in a subquery

  - by soulmerge

  Is it possible to reference an outer query in a subquery with MySQL? I know there are some cases where this is possible: SELECT * FROM table t1 WHERE t1.date = ( SELECT MAX(date) FROM table t2 WHERE t2.id = t1.id)` ); But I'm wondering if something like this could work: SELECT u.username, c._postCount FROM User u INNER JOIN ( SELECT p.user, COUNT(*) AS _postCount FROM Posting p --# This is the reference I would need: WHERE p.user = u.id ) c ON c.user = u.id WHERE u.joinDate < '2009-10-10'; I know I could achieve the same using a GROUP BY or by pulling the outer WHERE clause into the sub-query, but I need this for automatic SQL generation and cannot use either alternative for various other reasons.

• how to add a dynamic param

  - by user569846

  the jquery plugin that im using is this http://code.google.com/p/jquery-in-place-editor/ if i have a table like this <table> <thead> <tr> <th>id</th> <th>first name </th> <th>last name </th> </tr> </thead> <tbody> <tr> <td class="id">1</td> <td class="fname">sarmen</td> <td class="lname">mikey</td> </tr> <tr> <td class="id">2</td> <td class="fname">john</td> <td class="lname">angelo</td> </tr> <tr> <td class="id">3</td> <td class="fname">sarmen</td> <td class="lname">grande</td> </tr> </tbody> </table> and my js looked something like this $("td.fname").editInPlace({ url: 'ajax.php', params: '', show_buttons: true }); then lets say i click on the first record to edit it which is fname of sarmen. how can i pass a param that only accociates id 1 ? because if i do a query of lets say "update tbl_users set fname = '$_POST['update_value']' where fname = '$_POST['original_html']'" (note: im just showing an example so no need to clean posts if that was bothering you :) ) if i run this query the fname of sarmen will update in two records rather than one. How can i only update to id of 1 being to update only one record.

• How to make schema and code dynamic?

  - by Jonarch

  I want to make my database schema and application code as dynamic as possible to handle "unknown" use cases and changes. Developing in PHP and MySQL. Twice now I have had to change my entire schema including table and column names and this means the developers have to go back to the application code and modify all the SQL queries and table/columns names. So to prevent this I want to if just like we do on pages where we have page content, title bar etc dynamic like a %variable%, can we do it for the schema and maybe even for the php code functions and classes somehow? It takes weeks to re-do all changes like this vs if it is dynamic it can be done in under a day.

• [CSS] style input tag

  - by nosferat

  Hi! ASP.Net has a tag called CheckboxList. The output of this tag looks like this: <table class="checkbox"> <tbody> <tr> <td> <input id="/*longdynamicstring1*/" type="checkbox" name="/*longdynamicstring2*/" /> <label for="/*longdynamicstring1*/">Label Text</label> </td> </tr> </tbody> </table> I want to position the label and the input but I cannot find out how. Tried the following: .checkbox input{ padding-right: 5px; } and .checkbox input[type='checkbox'] { padding-right: 5px; } but neither of them had any effect. Because it's ASP I cannot set a class for the input elements and I cannot reference the id because it's dynamic.

• RoR model field without validators, has*, delegates, etc

  - by jackr

  How can I declare a field, in the Rails model, when it doesn't have any "has_" relations, or validations, or delegations? I just need to ensure its existence and column width in the schema. Currently, I have no mention of the field in the "schema section" of the model file, but it's referenced in various methods that use it, and this seems to work. However, depending on my exact creation workflow, the underlying database table may be created as t.binary "field_name", :limit => 32 or t.binary "field_name", :limit => 255 This is not a restriction on the value (any binary value is valid, even NULL), only on the table column declaration. As it happens, 32 is enough -- it never receives any larger value, it's only ever written to like this: self.field_name = SecureRandom.random_bytes(32)

• Can you modify SQL DB schema in a transaction to know if all changes were applied?

  - by Chris F

  As part of my (new) database version control methodology, I'm writing a "change script" and want the change script to insert a new row into the SchemaChangeLog table if the script is executed successfully, or to reverse changes if any single change in the script fails. Is it possible to do schema changes in a transaction and only if it gets committed to then do the INSERT? For example (psuedo-code, I'm not too good with SQL): SET XACT_ABORT ON BEGIN TRANSACTION PRINT 'Add Col2 to Table1' IF NOT EXIST (SELECT * FROM sys.columns WHERE NAME='Col2' AND object_id=OBJECT_ID('Table1')) BEGIN ALTER TABLE [dbo].[Table1] ADD Col2 int NULL END -- maybe COMMIT here? INSERT INTO SchemaChangeLog VALUES(...) COMMIT TRANSACTION

• Design question - loading info from DB

  - by eriks

  I need to build a class that will represent a row in some table in DB (lets say the table is 'Subscriber' and so is the class). I can have the class Subscriber which constructor receives the Objectkey of subscriber, retrieves info from DB and initializes its members. I add another class - SubscriberLoader which have a static method 'LoadSubscriber'. This method will receive the subscriber objectkey, retrieve info from DB, crate a Subscriber object and initialize its members. Subscriber constructor will be private and SubscirberLoader will be friend class of Subscriber - this way, client could build a Subscriber only using the loader. which of the two in better? any other suggestions?
