  • Change MS Access to Exclusive on the fly

    - by Nate
    I have a process in an MS Acess database that the users will usually run once daily, but could be more or less. It takes several minutes and requires temporary exclusive access because it deletes and recreates the main table. I have code to check to see if there are other users in the db before the process starts, but is there a way to change the access to "exclusive" at the beginning, and then change it back to open access at the end? Thanks for any help.

  • Magento user created attribute for products is not saved...

    - by Elzo Valugi
    I am fighting an apparently simple thing for about two days now. I hope somebody can help. I created the myUpdate EAV attribute class Company_Module_Model_Resource_Eav_Mysql4_Setup extends Mage_Eav_Model_Entity_Setup { public function getDefaultEntities() { return array( 'catalog_product' => array( 'entity_model' => 'catalog/product', 'attribute_model' => 'catalog/resource_eav_attribute', 'table' => 'catalog/product', 'additional_attribute_table' => 'catalog/eav_attribute', 'entity_attribute_collection' => 'catalog/product_attribute_collection', 'attributes' => array( 'my_update' => array( 'label' => 'My timestamp', 'type' => 'datetime', 'input' => 'date', 'default' => '', 'class' => 'validate-date', 'backend' => 'eav/entity_attribute_backend_datetime', 'frontend' => '', 'table' => '', 'source' => '', 'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL, 'visible' => true, 'required' => false, 'user_defined' => true, 'searchable' => false, 'filterable' => false, 'comparable' => false, 'visible_on_front' => false, 'visible_in_advanced_search' => false, 'unique' => false, 'apply_to' => 'simple', ) ) ) ); } } The attribute is created OK and on install appears correctly in the list of attributes. Later I do // for product 1 $product->setMyUpdate($stringDate); // string this format: yyyy-MM-dd HH:mm:ss $product->save(); // and saves without issues * in admin module But later when I do: $product = Mage::getModel('catalog/product')->load(1); var_dump($product->getMyUpdate()); // returns null Somehow the data is not really saved.. or I am not retrieving it correctly. Please advice on how to get the data and where the data is saved in the DB so I can check at if the insert is done correctly. Thanks.

  • SQL Server Transactions how can I commit my transaction

    - by codingguy3000
    I have SQL Server 2005 stored procedure. Someone one is calling my stored procedure within a transaction. In my stored proc I'm logging some information (insert into a table). When the higher level transaction rolls back it removes my insert. Is there anyway I can commit my insert and prevent the higher level rollback from removing my insert? Thanks

  • Detecting changes between rows with same ID

    - by Noah
    I have a table containing some names and their associated ID, along with a snapshot: snapshot, id, name I need to identify when a name has changed for an id between snapshots. For example, in the following data: 1, 0, 'MOUSE_SPEED' 1, 1, 'MOUSE_POS' 1, 2, 'KEYBOARD_STATE' 2, 0, 'MOUSE_BUTTONS' 2, 1, 'MOUSE_POS' 2, 2, 'KEYBOARD_STATE' ...the meaning of id 0 changed with snapshot 2, but the others remained the same. I'd like to construct a query that (ideally) returns: 1, 0, 'MOUSE_SPEED' 2, 0, 'MOUSE_BUTTONS' I am using PostgreSQL v8.4.2.

  • How to make a derived UITableVIew work

    - by justinhj
    I've made a new class in my Xcode project which is derived from UITableView I then drag a UITableView from in the interface builder onto my view and change the class of the object to my derived class. Then I drag the outlet from the table to the files owner and hook it up to an outlet variable in my main view, which is of the same type as my derived class. How do I also set up the datasource and delegate so that they belong to the derived class?

  • A better way to delete a list of elements from multiple tables

    - by manyxcxi
    I know this looks like a 'please write the code' request, but some basic pointer/principles for doing this the right way should be enough to get me going. I have the following stored procedure: CREATE PROCEDURE `TAA`.`runClean` (IN idlist varchar(1000)) BEGIN DECLARE EXIT HANDLER FOR NOT FOUND ROLLBACK; DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK; DECLARE EXIT HANDLER FOR SQLWARNING ROLLBACK; START TRANSACTION; DELETE FROM RunningReports WHERE run_id IN (idlist); DELETE FROM TMD_INDATA_INVOICE WHERE run_id IN (idlist); DELETE FROM TMD_INDATA_LINE WHERE run_id IN (idlist); DELETE FROM TMD_OUTDATA_INVOICE WHERE run_id IN (idlist); DELETE FROM TMD_OUTDATA_LINE WHERE run_id IN (idlist); DELETE FROM TMD_TEST WHERE run_id IN (idlist); DELETE FROM RunHistory WHERE id IN (idlist); COMMIT; END $$ It is called by a PHP script to clean out old run history. It is not particularly efficient as you can see and I would like to speed it up. The PHP script gathers the ids to remove from the tables with the following query: $query = "SELECT id, stop_time FROM RunHistory WHERE config_id = $configId AND save = 0 AND NOT(stop_time IS NULL) ORDER BY stop_time"; It keeps the last five run entries and deletes all the rest. So using this query to bring back all the IDs, it determines which ones to delete and keeps the 'newest' five. After gathering the IDs it sends them to the stored procedure to remove them from the associated tables. I'm not very good with SQL, but I ASSUME that using an IN statement and not joining these tables together is probably the least efficient way I can do this, but I don't know enough to ask anything but "how do I do this better?" If possible, I would like to do this all in my stored procedure using a query to gather all the IDs except for the five 'newest', then delete them. Another twist, run entries can be marked save (save = 1) and should not be deleted. The RunHistory table looks like this: CREATE TABLE `TAA`.`RunHistory` ( `id` int(11) NOT NULL auto_increment, `start_time` datetime default NULL, `stop_time` datetime default NULL, `config_id` int(11) NOT NULL, [...] `save` tinyint(1) NOT NULL default '0', PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8;

  • Automated download of website content using ASP.net

    - by Yaaqov
    Using ASP.net, what methods can I use to do the following: Open up a connection to a given URL to read HTML content Parse the given URL for hyperlinks, and place them in an array Loop through each hyperlink (only 1 level down), opening each one, saving the HTML contents in a table, and move to the next hyperlink until done. If ASP.net is not up to the task, other languages or free scripts/toolkits would be acceptable. Thanks.

  • Converting string to datetime

    - by duder
    I'm trying to enter a date in a mysql table `ssdate` datetime The function that produces the date can output it in 3 formats: 1276142400000 Thu Jun 10 00:00:00 GMT-0400 2010 Fri Jun 4 2010 I'm wondering which of these would be easiest to convert to this field format? Since I'm trying to save only the date, is there a better option than datetime that would work with one of these output formats?

  • Random record in ActiveRecord

    - by astrofoo
    I'm in need of getting a random record from a table via ActiveRecord. I've followed the example from Jamis Buck from 2006. However, I've also come across another way via a Google search (can't attribute with a link due to new user restrictions): rand_id = rand(Model.count) rand_record = Model.first(:conditions => [ "id >= ?", rand_id]) I'm curious how others on here have done it or if anyone knows what way would be more efficient.

  • I need to auto_increment a field in MySQL that is not primary key

    - by behrk2
    Hey everyone, Right now, I have a table whose primary key is an auto_increment field. However, I need to set the primary key as username, date (to ensure that there cannot be a duplicate username with a date). I need the auto_increment field, however, in order to make changes to row information (adding and deleting). What is normally done with this situation? Thanks!

  • Why is giving a fixed width to a label an accepted behavior?

    - by kemp
    There are a lot of questions about formatting forms so that labels align, and almost all the answers which suggest a pure CSS solution (as opposed to using a table) provide a fixed width to the label element. But isn't this mixing content and presentation? In order to choose the right width you basically have to see how big your longest label is and try a pixel width value until "it fits". This means that if you change your labels you also have to change your CSS.

  • How do I perform 'WHERE' on groups of rows?

    - by Drew
    I have a table, which looks like: +-----------+----------+ + person_id + group_id + +-----------+----------+ + 1 + 10 + + 1 + 20 + + 1 + 30 + + 2 + 10 + + 2 + 20 + + 3 + 10 + +-----------+----------+ I need a query such that only person_ids with groups 10 AND 20 AND 30 are returned (only person_id: 1). I am not sure how to do this, as from what I can see it would require me to group the rows by person_id and then select the rows which contain all group_ids. I'm looking for something which will preserve the use of keys without resorting to string operations on group_concat() or such.

The above example would produce the desired order: Home Sitemap Products Product 1 Product 1 Review Page Product 2
