  • using jquery to load data from mysql database

    - by Ieyasu Sawada
    I'm currently using jquery's ajax feature or whatever they call it. To load data from mysql database. Its working fine, but one of the built in features of this one is to load all the data which is on the database when you press on backspace and there's no character left on the text box. Here's my query: SELECT * FROM prod_table WHERE QTYHAND>0 AND PRODUCT LIKE '$prod%' OR P_DESC LIKE '$desc%' OR CATEGORY LIKE '$cat%' As you can see I only want to load the products which has greater than 0 quantity on hand. I'm using this code to communicate to the php file which has the query on it: $('#inp').keyup(function(){ var inpval=$('#inp').val(); $.ajax({ type: 'POST', data: ({p : inpval}), url: 'querys.php', success: function(data) { $('.result').html(data); } }); }); Is it possible to also filter the data that it outputs so that when I press on backspace and there's no character left. The only products that's going to display are those with greater than 0 quantity?

  • MongoDB map/reduce counts

    - by ibz
    The output from MongoDB's map/reduce includes something like 'counts': {'input': I, 'emit': E, 'output': O}. I thought I clearly understand what those mean, until I hit a weird case which I can't explain. According to my understanding, counts.input is the number of rows that match the condition (as specified in query). If so, how is it possible that the following two queries have different results? db.mycollection.find({MY_CONDITION}).count() db.mycollection.mapReduce(SOME_MAP, SOME_REDUCE, {'query': {MY_CONDITION}}).counts.input I thought the two should always give the same result, independent of the map and reduce functions, as long as the same condition is used.

  • Reading data in from file

    - by user667430
    Hi Here is link if you want to download application: Simple banking app Text file with data to read I am trying to create a simple banking application that reads in data from a text file. So far i have managed to read in all the customers which there are 20 of them. However when reading in the accounts and transactions stuff it only reads in 20 but there is alot more in the text file. Here is what i have so far.

    I'm having a dickens of a time installing Solaris Studio 12.2 on Ubuntu 10.04. I found this guide, however using the alien option isn't finding the correct files.

Any success from anyone else?

  • What should I learn from Scheme?

    - by bunglestink
    I was wondering what unique features I can learn from Scheme that would help me become a better programmer? I have a lot experience in mainstream languages, and I am looking to expand my horizons and learn about functional aspects that are missing from other languages. I am familiar with closures from javascript, lambda expressions from C#, and I was wondering what I can focus on that is lacking in other languages? Aside from the Lisp syntax, I feel like what I have seen so far I've already encountered in other languages. What is unique to Scheme/Lisp that will teach me something new?

  • DataSet with many OR clauses

    - by Silvan
    Hello :) I've got a little problem with a query which I create in the Visual Studio Designer. I need a query with a lot of 'OR'-clauses for the same column. I found the operator 'IN', but I don't know how to use that in the Visual Studio Designer: Example IN: SELECT EmployeeID, FirstName, LastName, HireDate, City FROM Employees WHERE City IN ('Seattle', 'Tacoma', 'Redmond') I tried to do it in this way: SELECT [MachineryId], [ConstructionSiteId], [DateTime], [Latitude], [Longitude], [HoursCounter] FROM [PositionData] WHERE [MachineryID] IN @MachineryIDs But this doesn't work. Is there another way to handle a lot of OR clauses? Thank you very much for your help.

  • Convert Google results object (pure js) to Python object

    - by colwilson
    So I'm trying to use Google Map suggest API to request place name suggestions. Unfortunately I can't find the docs for this bit. Here is an example URI: http://maps.google.com/maps/suggest?q=lon&cp=3&ll=55.0,-3.5&spn=11.9,1.2&hl=en&gl=uk&v=2 which returns: {suggestion:[{query:"London",... I want to use this in python (2.5). Now in proper JSON there would have been quotations around the keys like so: {"suggestion":[{"query":"London",... and I could have used simplejson or something, but as it is I'm a bit stuck. There are two possible solutions here; either I can get to the API code and find an option to return proper JSON, or I do that in python. Any ideas please.

  • Using a singleton database class in functions and multiple scripts(PHP) - best use methods

    - by dscher
    I have a singleton db connection which I get with: $dbConnect = myDatabase::getInstance(); which is easy enough. My question is what is the least rhetorical and legitimate way of using this connection in functions and classes? It seems silly to have to declare the variable global, pass it into every single function, and/or recreate this variable within every function. Is there another answer for this? Obviously I'm a noob and I can work my way around this problem 10 different ways, none of which is really attractive to me. It would be a lot easier if I could have that $dbConnect variable accessible in any function without needing to declare it global or pass it in. I do know I can add the variable to the $_SERVER array...is there something wrong with doing this? It seems somewhat inappropriate to me. Another quick question: Is it bad practice to do this: $result = myDatabase::getInstance()-query($query); from directly within a function?

  • Adding multiple byte arrays in c# [migrated]

    - by James P. Wright
    I'm working on a legacy system that uses byte arrays for permission levels. Example: 00 00 00 00 00 00 00 01 means they have "Full Control" 00 00 00 00 00 00 00 02 means they have "Add Control" 00 00 00 00 00 00 00 04 means they have "Delete Control" So, if a User has "00 00 00 00 00 00 00 07" that means they have all 3 (as far as it has been explained to me). Now, my question is that I need to know how to get to "0x07" when creating/checking records. I don't know the syntax for actually combining 0x01, 0x02 and 0x04 so that I come out with 0x07.

  • How Serializable works with insert in SQL Server 2005

    - by Spence
    G'day I think I have a misunderstanding of serializable. I have two tables (data, transaction) which I insert information into in a serializable transaction (either they are both in, or both out, but not in limbo). SET TRANSACTION ISOLATION LEVEL SERIALIZABLE BEGIN TRANSACTION INSERT INTO dbo.data (ID, data) VALUES (@Id, data) INSERT INTO dbo.transactions(ID, info) VALUES (@ID, @info) COMMIT TRANSACTION I have a reconcile query which checks the data table for entries where there is no transaction at read committed isolation level. INSERT INTO reconciles (ReconcileID, DataID) SELECT Reconcile = @ReconcileID, ID FROM Data WHERE NOT EXISTS (SELECT 1 FROM TRANSACTIONS WHERE data.id = transactions.id) Note that the ID is actually a composite (2 column) key, so I can't use a NOT IN operator My understanding was that the second query would exclude any values written into data without their transaction as this insert was happening at serializable and the read was occurring at read committed. I have evidence that reconcile is picking up entries

  • SSRS Column Grouping with specific order

  • Factory for arrays of objects in python

    - by Vorac
    Ok, the title might be a little misleading. I have a Window class that draws widgets inside itself in the constructor. The widgets are all of the same type. So I pass a list of dictionaries, which contain the parameters for each widget. This works quite nicely, but I am worried that the interface to callers is obfuscated. That is, in order to use Window, one has to study the class, construct a correct list of dictionaries, and then call the constructor with only one parameter - widgets_params. Is this good or bad design? What alternatives does the python syntax provide?

  • SQL join from multiple tables

    - by Kenny Anderson
    Hi all We've got a system (MS SQL 2008 R2-based) that has a number of "input" database and a one "output" database. I'd like to write a query that will read from the output DB, and JOIN it to data in one of the source DB. However, the source table may be one or more individual tables :( The name of the source DB is included in the output DB; ideally, I'd like to do something like the following (pseudo-SQL ahoy) SELECT output.UID, output.description, input.data from output.dbo.description LEFT JOIN (SELECT input.UID, input.data FROM [output.sourcedb].dbo.datatable ) AS input ON input.UID=output.UID Is there any way to do something like the above - "dynamically" specify the database and table to be joined on for each row in the query?

  • Is there a way to give a subquery an alias in Oracle 10g SQL?

    - by Matt Pascoe
    Is there a way to give a subquery in Oracle 11g an alias like: select * from (select client_ref_id, request from some_table where message_type = 1) abc, (select client_ref_id, response from some_table where message_type = 2) defg where abc.client_ref_id = def.client_ref_id; Otherwise is there a way to join the two subqueries based on the client_ref_id. I realize there is a self join, but on the database I am running on a self join can take up to 5 min to complete (there is some extra logic in the actual query I am running but I have determined the self join is what is causing the issue). The individual subqueries only take a few seconds to complete by them selves. The self join query looks something like: select st.request, st1.request from some_table st, some_table st1 where st.client_ref_id = st1.client_ref_id;

  • how to configure hibernate not to update @Version on each access to entity

    - by radai
    i have a simple query that returns an entity, and when i look at hibernate SQL output i see that when i execute this query hibernate updates the @Version field (on each consecutive read the @version field is updated). i dont modify anything in the entity i fetch, and i dont pass is as an argument to either persist or merge. this effectively means every read i make turns into a read+write. i've tried setting the lock mode t oboth NONE (jpa 2) and READ (jpa 1) to no avail. is there any way to achieve this? if so, is there any way to set this as the default behavior in persistence.xml in some way ? im using jpa2 over hibernate 3.6

  • How to use SQL - INSERT...ON DUPLICATE KEY UPDATE?

    - by Probocop
    Hi, I have a script which captures tweets and puts them into a database. I will be running the script on a cronjob and then displaying the tweets on my site from the database to prevent hitting the limit on the twitter API. So I don't want to have duplicate tweets in my database, I understand I can use 'INSERT...ON DUPLICATE KEY UPDATE' to achieve this, but I don't quite understand how to use it. My database structure is as follows. Table - Hash id (auto_increment) tweet user user_url And currently my SQL to insert is as follows: $tweet = $clean_content[0]; $user_url = $clean_uri[0]; $user = $clean_name[0]; $query='INSERT INTO hash (tweet, user, user_url) VALUES ("'.$tweet.'", "'.$user.'", "'.$user_url.'")'; mysql_query($query); How would I correctly use 'INSERT...ON DUPLICATE KEY UPDATE' to insert only if it doesn't exist, and update if it does? Thanks

  • Correct handling of return data

    - by Serhiy
    Hello, I have a question related to correct handling of returns of the DAO library I'm writing for one project. This library probably is going to be used by another people and I want to do it correctly. So I would like to know, how I should deal with return statements of the functions of my DAO. Example 1 I have function to getCustomer which should return String. In case query doesn't return any result should I return null, empty string or throw some kind of Exception? Example 2 I have function getCutomerList which return ArrayList. In case query doesn't return any result should I return null, empty ArrayList or throw some Exception? Example 3 Some sql exception was detected, what should I do: throw exception or do try..catch of the block where it can occur? What is the "good" practice or "best" practice to apply in my case? Thanks on advance, Serhiy.

  • Finding efficient overlapped entries in a SQL table

    - by Laoneo
    What is the most efficient way to find all entries which do overlap with others in the same table? Every entry has a start and end date. For example I have the following database setup: CREATE TABLE DEMO ( DEMO_ID int IDENTITY , START date NOT NULL , END date NOT NULL }; INSERT INTO DEMO (DEMO_ID, START, END) VALUES (1, '20100201', '20100205'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (2, '20100202', '20100204'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (3, '20100204', '20100208'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (4, '20100206', '20100211'); My query looks as follow: SELECT DISTINCT * FROM DEMO A, DEMO B WHERE A.DEMO_ID != B.DEMO_ID AND A.START < B.END AND B.START < A.END The problem is when my demo table has for example 20'000 rows the query takes too long. My environment is MS SQL Server 2008. Thanks for any more efficient solution

  • How to bring out checboxes based on drop down list selection from DB

    - by user2199877
    I got stuck again. Can't overcome this step: loop through (in a form of checkboxes) pallets based on the lot drop down list selection, so it can be further submitted to complete the table. Please, please help. So, basically, first submit button (drop down menu) brings into the table lot number and description and also checkboxes to choose pallets. Second submit button (checboxes) brings into the table pallets numbers and weights. Thank you for any help. <?php mysql_connect('localhost','user',''); mysql_select_db('base'); $query="SELECT DISTINCT lot_number FROM pl_table"; $result=mysql_query($query); ?> <form action="" method="POST"> <select name="option_chosen"> <option>-- Select lot --</option> <?php while(list($lot_number)=mysql_fetch_row($result)) { echo "<option value=\"".$lot_number."\">".$lot_number."</option>"; } ?> </select> <input type='submit' name='submitLot' value='Submit' /> </form> <!-- need help here <h4>-- Select pallets --</h4> <form action="" method="POST"> <input type='submit' name='submitPal' value='Submit'/> </form> --> <table border="1" id="table"> <tr> <th width=80 height=30>Lot<br/>number</th> <th width=110 height=30>Description</th> <th width=90 height=30>Pallet<br/>number</th> <th width=60 height=30>Net</th> <th width=60 height=30>Gross</th> </tr> <?php if($_SERVER['REQUEST_METHOD'] =='POST') {$option_chosen=$_POST['option_chosen']; $query="SELECT * FROM pl_table WHERE lot_number='$option_chosen'"; $run=mysql_query($query); $row=mysql_fetch_array($run, MYSQLI_ASSOC); echo "<tr><td>".''."</td>"; echo "<td rowspan='5'>".$row['descr']."</td>"; echo "<td><b>".'Total weight'."<b></td>"; echo "<td>".''."</td><td>".''."</td></tr>"; echo "<td>".$row['lot_number']."</td>"; echo "<td colspan='3'>".''."</td>"; //This to be echoed when "select pallets" submited //echo "<tr><td>".$row['lot_number']."</td>"; //echo "<td>".$row['pallet_number']."</td>"; //echo "<td>".$row['net']."</td><td>".$row['gross']."</td></tr>"; } ?> </table> the table +--------------------------+-------------------------+---------+-------+ | id | lot_number | descr | pallet_number | net | gross | +--------------------------+-------------------------+---------+-------+ | 1 | 111 | black | 1 | 800 | 900 | | 2 | 111 | black | 2 | 801 | 901 | | 3 | 111 | black | 3 | 802 | 902 | | 4 | 222 | white | 1 | 800 | 900 | | 5 | 222 | white | 2 | 801 | 901 | | 6 | 222 | white | 3 | 802 | 902 | +--------------------------+-------------------------+---------+-------+

  • Need help setting up json array

    - by torr
    A database query returns several rows which I loop through as follows: foreach ($query->result() as $row) { $data[$row->post_id]['post_id'] = $row->post_id; $data[$row->post_id]['post_type'] = $row->post_type; $data[$row->post_id]['post_text'] = $row->post_text; } If I json_encode the resulting array ($a['stream']) I get { "stream": { "1029": { "post_id": "1029", "post_type": "1", "post_text": "bla1", }, "1029": { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, "1029": { "post_id": "1031", "post_type": "2", "post_text": "bla3", } } } But the json should actually look like this: { "stream": { "posts": [{ "post_id": "1029", "post_type": "1", "post_text": "bla1", }, { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, { "post_id": "1031", "post_type": "2", "post_text": "bla3", }] } } How should I build my array to get this json right?
