  • JDBC going to the wrong address

    - by DCSoft
    When I try and connect it my mysql database with JDBC in java, it doesn't go to my web server. Here is the code String dbtime; String dbUrl = "jdbc:mysql://184.172.176.18:3306/dcsoft_dcsoft_balloon"; String dbUser = "myuser"; String dcPass = "mypass"; String dbClass = "com.mysql.jdbc.Driver"; String query = "Select * FROM users"; try { Class.forName("com.mysql.jdbc.Driver"); Connection con = DriverManager.getConnection(dbUrl, dbUser, dcPass); Statement stmt = con.createStatement(); ResultSet rs = stmt.executeQuery(query); while (rs.next()) { dbtime = rs.getString(1); System.out.println(dbtime); } //end while con.close(); } //end try catch(ClassNotFoundException e) { e.printStackTrace(); } catch(SQLException e) { e.printStackTrace(); } This code is supposed to go to my web server but it gives this error java.sql.SQLException: Access denied for user 'dcsoft_dcsoft_java'@'jamesposse.force9.co.uk' (using password: YES) jamesposse.force9.co.uk is the not the address im trying to connect to I'm trying to connect to 184.172.176.18:3306.

  • Facebook Page Statuses API

    - by Simon R
    I've got a curl function in php which posts a status update to our facebook page. However, when I post the update it makes the status appear from me personally rather than me the group. Does anyone know how you can post as administrator of the group. The script is as follows; $xPost['access_token'] = "[key]" $xPost['message'] = "Posting a message test."; $query = http_build_query($xPost); $ch = curl_init('https://graph.facebook.com/broadland/feed'); curl_setopt($ch, CURLOPT_VERBOSE, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 120); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $query); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_CAINFO, NULL); curl_setopt($ch, CURLOPT_CAPATH, NULL); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0); $result = curl_exec($ch);

  • Large Product catalog with statistics - alternatives to Sql Server?

    - by Eric P
    I am building UI for a large product catalog (millions of products). I am using Sql Server, FreeText search and ASP.NET MVC. Tables are normalized and indexed. Most queries take less then a second to return. The issue is this. Let's say user does the search by keyword. On search results page I need to display/query for: First 20 matching products (paged, sorted) Total count of matching products for paging List of stores only of matching products List of brands only of matching products List of colors only of matching products Each query takes about .5 to 1 seconds. Altogether it is like 5 seconds. I would like to get the whole page to load under 1 second. There are several approaches: Optimize queries even more. I already spent a lot of time on this one, so not sure it can be pushed further. Load products first, then load the rest of the information using AJAX. More like a workaround. Will need to revise UI. Re-organize data to be more Report friendly. Already aggregated a lot of fields. I checked out several similar sites. For ex. zappos.com. Not only they display the same information as I would like in under 1 second, but they also include statistics (number of results in each category). The following is the search for keyword "white" http://www.zappos.com/white How do sites like zappos, amazon make their results, filters and stats appear almost instantly?

  • Why does this sql statement keep saying it is a boolean and not a paramter? (php/Mysql)

    - by ggfan
    In this statement, I am trying to see if there if the latest posting in the database that has the exact same title, price, city, state, detail. If there is, then it would say to the user that the exact post has been already made; if not then insert the posting into the dbc. (This is one type of check so that users can't accidentally post twice. This may not be the best check, but this statement error is annoying me, so I want it to work :)) Why won't this sql work? I think it's not letting the title=$title and not getting the value in the $title... ERROR: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in postad.php on line 365 //there is a form that users fill out that has title, price, city, etc <form> blah blah </form> //if users click submit, then does all the checks and if all okay, insert to dbc if (isset($_POST['submit'])) { // Grab the pposting data from the POST and gets rid of any funny stuff $title = mysqli_real_escape_string($dbc, trim($_POST['title'])); $price = mysqli_real_escape_string($dbc, trim($_POST['price'])); $city = mysqli_real_escape_string($dbc, trim($_POST['city'])); $state = mysqli_real_escape_string($dbc, trim($_POST['state'])); $detail = mysqli_real_escape_string($dbc, trim($_POST['detail'])); if (!is_numeric($price) && !empty($price)) { echo "<p class='error'>The price can only be numbers. No special characters, etc</p>"; } //Error problem...won't let me set title=$title, detail=$detail, etc. //this statement after all the checks so that none of the variables are empty $query="Select * FROM posting WHERE user_id={$_SESSION['user_id']} AND title=$title AND price=$price AND city=$city AND state=$state AND detail=$detail"; $data = mysqli_query($dbc, $query); if(mysqli_num_rows($data)==1) { echo "You already posted this ad. Most likely caused by refreshing too many times."; } }

  • DrawRect on the iPhone vs. the Mac

    - by Joe Cannatti
    I am an experienced iPhone dev beginning to work on my first Mac app. One thing that is really throwing me off is the differences between UIView and NSView. It seems that I cannot set the background color of a NSView via interface builder as I can with a UIView. It also seems that I cannot do it by simply sending a setBackgroundColor: message to it. All the examples I have seen are overriding drawRect: in a subclass of NSView. Is that really the only way to do it? What is the conceptual difference here, and why is it this way? NOTE: I am only trying to set the background color to the default grey.

  • how to find missing rows in oracle

    - by user203212
    Hi, I have a table called 2 tables create table ORDERS ( ORDER_NO NUMBER(38,0) not null, ORDER_DATE DATE not null, SHIP_DATE DATE null, SHIPPING_METHOD VARCHAR2(12) null, TAX_STATUS CHAR(1) null, SUBTOTAL NUMBER null, TAX_AMT NUMBER null, SHIPPING_CHARGE NUMBER null, TOTAL_AMT NUMBER null, CUSTOMER_NO NUMBER(38,0) null, EMPLOYEE_NO NUMBER(38,0) null, BRANCH_NO NUMBER(38,0) null, constraint ORDERS_ORDERNO_PK primary key (ORDER_NO) ); and create table PAYMENTS ( PAYMENT_NO NUMBER(38,0) NOT NULL, CUSTOMER_NO NUMBER(38,0) null, ORDER_NO NUMBER(38,0) null, AMT_PAID NUMBER NULL, PAY_METHOD VARCHAR(10) NULL, DATE_PAID DATE NULL, LATE_DAYS NUMBER NULL, LATE_FEES NUMBER NULL, constraint PAYMENTS_PAYMENTNO_PK primary key (PAYMENT_NO) ); I am trying to find how many late orders each customer have. the column late_days in PAYMENTS table has how many days the customer is late for making payments for any particular order. so I am making this query SELECT C.CUSTOMER_NO, C.lname, C.fname, sysdate, COUNT(P.ORDER_NO) as number_LATE_ORDERS FROM CUSTOMER C, orders o, PAYMENTS P WHERE C.CUSTOMER_NO = o.CUSTOMER_NO AND P.order_no = o.order_no AND P.LATE_DAYS>0 group by C.CUSTOMER_NO, C.lname, C.fname That means, I am counting the orders those have any late payments and late_days0. But this is giving me only the customers who have any orders with late_days0, but the customers who does not have any late orders are not showing up. so if one customer has 5 orders with late payments then it is showing 5 for that customer, but if a customer have 0 late orders,that customer is not selected in this query. Is there any way to select all the customers , and if he has any late orders, it will show the number and also if he does not have any late orders, it will show 0.

  • Objective C memory leaking

    - by Jakub Lédl
    Hi everyone, I'm creating one Cocoa application for myself and I found a problem. I have two NSTextFields and they're connected to each other as nextKeyViews. When I run this app with memory leaks detection tool and tab through those 2 textboxes for a while, enter some text etc., I start to leak memory. It shows me that the AppKit library is responsible, the leaked objects are NSCFStrings and the responsible frames are [NSEvent charactersIgnoringModifiers] and [NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:]. I know this is quite a brief and incomplete description, but does anyone have any ideas what could be the problem? Also, I don't use GC, so I release my instance variables in the controllers dealloc. What about the outlets? Since IBOutlet is just a mark for Interface Builder and doesn't actually mean anything, should I release them too?

  • MySQL Datefields: duplicate or calculate?

    - by Konerak
    We are using a table with a structure imposed upon us more than 10 years ago. We are allowed to add columns, but urged not to change existing columns. Certain columns are meant to represent dates, but are put in different format. Amongst others: * CHAR(6): YYMMDD * CHAR(6): DDMMYY * CHAR(8): YYYYMMDD * CHAR(8): DDMMYYYY * DATE * DATETIME Since we now would like to do some more complex queries, using advanced date functions, my manager proposed to d*uplicate those problem columns* to a proper FORMATTED_OLDCOLUMNNAME column using a DATE or DATETIME format. Is this the way to go? Couldn't we just use the STR_TO_DATE function each time we accessed the columns? To avoid every query having to copy-paste the function, I could still work with a view or a stored procedure, but duplicating data to avoid recalculation sounds wrong. Solutions I see (I guess I prefer 2.2.1) 1. Physically duplicate columns 1.1 In the same table 1.1.1 Added by each script that does a modification (INSERT/UPDATE/REPLACE/...) 1.1.2 Maintained by a trigger on each modification 1.2 In a separate table 1.2.1 Added by each script that does a modification (INSERT/UPDATE/REPLACE/...) 1.2.2 Maintained by a trigger on each modification 2. On-demand transformation 2.1 Each query has to perform the transformation 2.1.1 Using copy-paste in the source code 2.1.2 Using a library 2.1.3 Using a STORED PROCEDURE 2.2 A view performs the transformation 2.2.1 A separate table replacing the entire table 2.2.2 A separate table just adding the date-fields for the primary keys Am I right to say it's better to recalculate than to store? And would a view be a good solution?

  • Assign TableView column binding to a specific core-data object in to-many related entity based on se

    - by snown27
    How would I assign a column of a TableView to be a specific entry in a Core Data entity that is linked to the NSArrayController via a to-many relationship? For example Entity: MovieEntity Attributes: title(NSString), releaseDate(NSDate) Relationship: posters<-->> PosterEntity Entity:PosterEntity Attributes: imageLocation(NSURL), default(BOOL) Relationships: movie<<--> MovieEntity So I have a three column table that I want to display the Poster, Title, and Release Date attributes in, but as one movie could potentially have several different style's of posters how do I get the poster column to only show the one that's marked default? Since the rest of the table is defined in Interface Builder I would prefer to keep it that way for the sake of keeping the code as clean as possible, but if this can only be done programmatically then I'm all ears. I just wanted to give preference in case there's more than one way to skin a cat, so to speak.

  • problem in variables in jquery

    - by Alvin
    Hi, I don't understand why I'm not getting the message as "username already exits" if type the username which is already in database. If the username in a server, then it is returning the value as "1" otherwise empty, and despite of successfully getting the value from the server based on username is present or not, and assigning the value to variable "x", I'm unable to get message when I pass already exist username. May I know? $(document).ready(pageInit); function pageInit() { $('#1').bind('blur',go); } function go() { var value = $('#1').val(); var x = 0; $.post('just.do',{username:value},function(data){ x = data; } ); if(x) { $('#para').show(); $('#para').html("Username already exits"); return false; } else { $('#para').hide(); return true; } }; EDIT: This is what I'm doing in post request in servlets: String user1 = request.getParameter("username"); if(user != null) { String query = "Select * from users where user_name="+"\""+user+"\""; b = db.doExecuteQuery(stmt,query); if(b) { out.write("1"); } }

  • What's the best way to access a MS Access database using PHP?

    - by Jack Roscoe
    Hi, I need to access some data from an MS Access database and retrieve some data from it using PHP. I've looked around the web, and found the following line which seems to correctly connect to the database: $conn->Open("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=C:\wamp\www\data\MYDB.mdb"); However, I have tried to retrieve some data in the following way: $query = "SELECT pageid FROM pages_table"; $result = mysqli_query($conn, $query); $amount_of_pages = 0; if(mysqli_num_rows($result) <= 0) echo "No results found."; else while($row = mysqli_fetch_array($result, MYSQL_ASSOC)) $amount_of_pages++; And was presented with the following errors: Warning: mysqli_query() expects parameter 1 to be mysqli, object given in C:\wamp\www\data\index.php on line 19 Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, null given in C:\wamp\www\data\index.php on line 23 No results found. I don't really understand the connection to the Access database, is there something I should be doing differently? Thanks in advance for any help.

  • Ruby on Rails - Calendar Display

    - by user335725
    We want to create a calendar view in a room scheduling application. The outcome we want is to have hours open (variable depending on day) across the top of the grid and the names of the rooms down the left side of the grid. The body would be populated with bookings for that day. The visual we're seeking is similar to the "Weekly Builder" plugin for Rails (http://dmix.ca/2009/06/weeklybuilder-a-weekly-calendar-plugin-for-rails/). We've tried using CSS to create variably-sized images, but this isn't working out. Are there any plugins available or other ways anyone can think of to accomplish this kind of visual? Thanks

  • HTML, Javascript, PHP and Actionscript all in one Eclipse install (2010)

    - by ThunderChunky_SF
    I just wanted to poll the community and see which plugins people are currently using to get all of these different technologies running in Eclipse. I saw this thread which mentioned Spket & WPT: http://stackoverflow.com/questions/1575617/eclipse-which-plugins-for-html-javascript But I noticed that Spket doesn't seem to have been updated since October of 2009 so I'm wondering if it's still a good tool to use. I'm not sure what would be best for PHP since it seems like some of the tools are disjointed at the moment. For Actionscript I know I can just install the latest Flash Builder plugin and be done. Any suggestions are greatly appreciated.

  • How do I iterate through hierarchical data in a Sql Server 2005 stored proc?

    - by AlexChilcott
    Hi, I have a SqlServer2005 table "Group" similar to the following: Id (PK, int) Name (varchar(50)) ParentId (int) where ParentId refers to another Id in the Group table. This is used to model hierarchical groups such as: Group 1 (id = 1, parentid = null) +--Group 2 (id = 2, parentid = 1) +--Group 3 (id = 3, parentid = 1) +--Group 4 (id = 4, parentid = 3) Group 5 (id = 5, parentid = null) +--Group 6 (id = 6, parentid = 5) You get the picture I have another table, let's call it "Data" for the sake of simplification, which looks something like: Id (PK, int) Key (varchar) Value (varchar) GroupId (FK, int) Now, I am trying to write a stored proc which can get me the "Data" for a given group. For example, if I query for group 1, it returns me the Key-Value-Pairs from Data where groupId = 1. If I query for group 2, it returns the KVPs for groupId = 1, then unioned with those which have groupId = 2 (and duplicated keys are replaced). Ideally, the sproc would also fail gracefully if there is a cycle (ie if group 1's parent is group 2 and group 2's parent is group 1) Has anyone had experience in writing such a sproc, or know how this might be accomplished? Thanks guys, much appreciated, Alex

  • Pass variable to Info Window in FusionTableLayer

    - by user1030205
    I am building a web application that includes a Google Map layered with data from a Google Fusion Table. I have defined the info window for the markers in the Fusion Table and all is rendering as expected, but I have one issue. I need to pass a session variable from my web application to be included in the links that are defined in the info window, but can't seem to find a way to do this. Below is the javascript I am currently using to render the map: var myOptions = { zoom: 10, mapTypeId: google.maps.MapTypeId.ROADMAP, center: new google.maps.LatLng( 40.4230,-98.7372) } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); // Weather weatherLayer = new google.maps.weather.WeatherLayer({ temperatureUnits: google.maps.weather.TemperatureUnit.FAHRENHEIT }); weatherLayer.setMap(map); //Hobby Stores var storeLayer = new google.maps.FusionTablesLayer({ query: { select: "col2", from: "3991553" }, map: map, supressInfoWindows: true }); //Club Sites var siteLayer = new google.maps.FusionTablesLayer({ query: { select: "col13", from: "3855088" }, styles: [{ markerOptions: { iconName: "airports" }}], map: map, supressInfoWindows: true }); I'd like to be able to pass some type of parameter in the call to google.maps.FusionTableLayer that passes a value to be include in the info window, but can't find a way to do this. To view the actual page, visit www.dualrates.com. Enter your zipcode and select one of the airport markers to see the info window. You may have to zoom the map out to see an airfield.

  • SQL Analysis Services - Dimension attributes with a "many" cardinality

    - by MonkeyBrother
    I am creating a cube with the following tables: Customer CustomerID, Name Customer Rep CustomerID, RepID Rep RepID, Name The important thing here is that there is a many to many relationship between Reps and Customers. I want to be able to ask the question "How much sales for customers working with rep 'A'?" In the data source view i set up the relationships between both customerid columns and both repid columns. I set up the rep attribute in the dimension builder and when I try to build the cube I get this error: Errors in the high-level relationship engine. the 'Rep' table that is required for a join cannot be reached based on the relationships in the data source view.

  • How can I get a list of modified records from a SQL Server database?

    - by Pixelfish
    I am currently in the process of revamping my company's management system to run a little more lean in terms of network traffic. Right now I'm trying to figure out an effective way to query only the records that have been modified (by any user) since the last time I asked. When the application starts it loads the job information and caches it locally like the following: SELECT * FROM jobs. I am writing out the date/time a record was modified ala UPDATE jobs SET Widgets=@Widgets, LastModified=GetDate() WHERE JobID=@JobID. When any user requests the list of jobs I query all records that have been modified since the last time I requested the list like the following: SELECT * FROM jobs WHERE LastModified>=@LastRequested and store the date/time of the request to pass in as @LastRequest when the user asks again. In theory this will return only the records that have been modified since the last request. The issue I'm running into is when the user's date/time is not quite in sync with the server's date/time and also of server load when querying an un-indexed date/time column. Is there a more effective system then querying date/time information?

  • servlet connection to DB

    - by underW
    Initially, after reading books on the subject, I firmly believed that the algorithm for working with a database from a servlet is as follows: create a connection - connect to the database - form a request - send the request to the database - get the query results - process them - close connection - OK. Now, with a better understanding of the practical side, I realized that nobody does it that way, and everything happens through a connection pool according to the following algorithm: initialize the servlet - create a connection pool - a request comes from a user - take a free connection from the pool - form a request - send the request to the database - get the query results - process them - return the connection back to the pool - ok. Now I have this problem: We have 100 users, they are divided into 10 groups, each group has it's own username and password to connect to the database. Moreover, each group may have different rights to the database. How am I supposed to use a connection pool in this situation? If I understand correctly, a pool is nothing more than just a group of similar connections with a single login and password. And here I have 10 pairs of username / password. It looks like I cannot use the pool in this situation. What should I do?
