  • mysql: select ... where id = any value. is it possible?

    - by Syom
    look at this table please table |id| |name| |order| i must get the rows, where name = something and order = somevalue so i write select `id` from `table` where `name` = 'something' and `order` = 'somevalue' but depend on php logic, sometimes i need to get all rows, where name = somethimg, independently of order value. i don't want to change the query structure, because in practise there are many number of fields, and possible count of queries will became very big. so i want to save the structure of query, and when i need to select just by name, i want to write something like this select `id` from `table` where `name` = 'something' and `order` = any value is it possible? maybe the question is incomprehensible, at least i tried;) sorry for bad english thanks

  • Echo mysql results in a loop?

    - by Roy D. Porter
    I am using turn.js to make a book. Every div within the 'deathnote' div becomes a new page. <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page </div> //ends book What I am doing is trying to get 3 'content' (content being a name and cause of death) divs onto 1 page, and then generate a new page. So here is what i want: <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"> //creates new page but leaves it open <div> CONTENT </div> <div> CONTENT </div> <div> CONTENT </div> </div> //ends the page </div> //ends book Seems simple enough, however the content is data from a MySQL DB, so i have to echo it in using PHP. Here is what i have so far <div id="deathnote"> <div style="background-image:url(images/coverpage.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <?php $pagecount = 0; $db = new mysqli('localhost', 'username', 'passw', 'DB'); if($db->connect_errno > 0){ die('Unable to connect to database [' . $db->connect_error . ']'); } $sql = <<<SQL SELECT * FROM `TABLE` SQL; if(!$result = $db->query($sql)){ die('There was an error running the query [' . $db->error . ']'); } //IGNORE ALL OF THE GARBAGE ABOVE. IT IS SIMPLE CONNECTING SCRIPT THAT I KNOW WORKS //THE METHOD I AM HAVING TROUBLE WITH IS BELOW $pagecount = 0; while($row = $result->fetch_assoc()){ //GETS THE VALUE (and makes sure it isn't nothing echo '<div style="background-image:url(images/paper.jpg);">'; //THIS OPENS A NEW PAGE while ($pagecount !== 3) { //KEEPS COUNT OF HOW MUCH CONTENT DIVS IS ON THE PAGE while($row = $result->fetch_assoc()){ //START A CONTENT DIV echo '<div class="content"><div class="name">' . $row['victim'] . '</div><div class="cod">' . $row['cod'] . '</div></div>'; //END A CONTENT DIV $pagecount++; //UP THE PAGE COUNT } } $pagecount=0; //PUT IT BACK TO 0 echo '</div>'; //END PAGE } $db->close(); ?> <div style="background-image:url(images/backpage.jpg);"></div> //BACK PAGE </div> At the moment i seem to be causing and infinite loop so the page won't load. The problem resides within the while loops. Any help is greatly appreciated. Thanks in advance guys. :)

  • Problem with returning values from a helper method in Rails

    - by True Soft
    I want to print some objects in a table having 2 rows per object, like this: <tr class="title"> <td>Name</td><td>Price</td> </tr> <tr class="content"> <td>Content</td><td>123</td> </tr> I wrote a helper method in products_helper.rb, based on the answer of this question. def write_products(products) products.map { |product| content_tag :tr, :class => "title" do content_tag :td do link_to h(product.name), product, :title=>product.name end content_tag :td do product.price end end content_tag :tr, :class => "content" do content_tag :td, h(product.content) content_tag :td, product.count end }.join end But this does not work as expected. It only returns the last node - the last <td>123</td> What should I do to make it work?

  • How to optimize this Linq query

    I am trying to optimize this query. It is not slow for now but I am expecting a spike to hit this query in the near future.

  • How to tell when my batch of EAP calls are completed?

    - by codemonkie
    This is following my question: http://stackoverflow.com/questions/2607038/c-how-to-consume-web-service-adheres-to-the-event-based-asynchronous-pattern My program is calling the DoStuffAsync() x many times in a batch, hence the callback will get invoked the same number of times upon OnComplete(). Is there a way to find out when my batch is finished such that I can generate a report on the success/failed results? All I can think of is to have a static count variable for x and deduct 1 every time OnComplete() is called, but its kind of silly and error prone I'm afraid. TIA.

  • How to get #entries of last hour in MySQL, correcting for timezone?

    - by Ferdy
    I am storing activity entries in a MySQL table. The table has a date_created field of type timestamp and through PHP I insert the activity entries based on GMT: $timestamp = gmdate("Y-m-d H:i:s", time()); This works fine. On my client I am on GMT+2. If it is 16:00 here and I insert an entry, it is stored in MySQL as 14:00. This is as expected I guess. My Now I would like to get the number of activity entries from MySQL within the last hour. I'm using the following query: SELECT COUNT(id) as cnt FROM karmalog WHERE user_id = ' 89' AND event='IMG_UPD' AND date_created > DATE_SUB(CURRENT_TIMESTAMP, INTERVAL 1 HOUR) This returns nothing, because CURRENT_TIMESTAMP uses the MySQL timezone settings, which is set to SYSTEM, which is set to GMT+2. I guess what I am looking for is a GMT_CURRENTTIMESTAMP in MySQL, is there such a thing?

  • IntPtr arithmetics

    - by Luca
    I tried to allocate an array of structs in this way: struct T { int a; int b; } data = Marshal.AllocHGlobal(count*Marshal.SizeOf(typeof(T)); ... I'd like to access to allocated data "binding" a struct to each element in array allocated with AllocHGlobal... something like this T v; v = (T)Marshal.PtrToStructure(data+1, typeof(T)); but i don't find any convenient way... why IntPtr lack of arithmetics? How can I workaround this is a "safe" way? Someone could confirm that PtrToStructure function copy data into the struct variable? In other words, modifing the struct reflect modifications in the structure array data, or not? Definitely, I want to operate on data pointed by an IntPtr using struct, without copying data each time, avoiding unsafe code. Thank all!

  • Obtain Update Table Lock at start of Stored Procedure in SQL Server

    - by Jim Hurne
    I'm writing a SQL Server stored procedure in which I want to lock a table for update before executing the body of the stored procedure. I don't want to prevent other processes from reading the table, but I do want to prevent other processes updating the table. Here is my first attempt: CREATE PROCEDURE someProcedure BEGIN SET TRANSACTION ISOLATION LEVEL READ COMITTED BEGIN TRANSANCTION SELECT COUNT(*) FROM TheTable WITH (UPDLOCK, TABLOCK) -- Pause procedure so that we can view the locks with sp_lock WAITFOR DELAY '00:15' -- Do stuff COMMIT END When I execute the stored procedure, and invoke sp_lock, I see that the table is indeed locked. However, it's locked with an Exclusive lock instead of an update lock: spid | dbid | ObjId | IndId | Type | Resource | Mode | Status ------------------------------------------------------------------ 63 | 10 | 233208031 | 0 | TAB | | X | GRANT How can I get an update (U) lock instead?

Is it possible to load the .wav file once upon starting the game and keep it in memory and use it later across the game? Or is it possible to wait for 1-2 seconds for the sound to load finish?

  • Removing duplicate SQL records to permit a unique key

    - by j pimmel
    I have a table ('sales') in a MYSQL DB which should have rightfully have had a unique constraint enforced to prevent duplicates. To first remove the dupes and set the constraint is proving a bit tricky. Table structure (simplified): 'id (unique, autoinc)' product_id The goal is to enforce uniqueness for product_id. The de-duping policy I want to apply is to remove all duplicate records except the most recently created, eg: the highest id Or to put another way, I would like to delete duplicate records, excluding the ids matched by the following query: select id from sales s inner join (select product_id, max(id) as maxId from sales group by product_id having count(product_id) > 1) groupedByProdId on s.product_id and s.id = groupedByProdId.maxId I've struggled with this on two fronts - writing the query to select the correct records to delete and then also the constraint in MYSQL where a subselect FROM clause of a DELETE cannot reference the same table from which data is being removed.

  • Determining Connections between data in a single table

    - by user1689749
    Hi I'm a BA / programmer type doing data analysis on a legacy system. I've been teaching myself SQL to help, but I've appeared to hit upon a problem bigger than my abilities. I have two tables (generalized for simplicity): Table Objects Object_PK Table Components Component_PK Object_FK Component_Type There are 100+ distinct values in Component_Type_Code. Given that any object can have N number of Components, how can I see which Component_Type(s) appear with other Component_Type(s)? For example, the following query tells me what component_types appear with the component_type 'Component_type_1': select component_type_code, count(*) from components where object_fk in ( select object_fk from components where component_type_code = 'component_type_1' ) group by component_type_code I'd like to get a query to show me all connections My apologies for the formatting. Any help is appreciated. I've looked at cube and rollup, but didn't know how to apply to this situtation.
