  • Is it possible to create multi-tiered WHERE statements in mySQL

    - by Brendan
    I'm currently developing a program that will generate reports based upon lead data. My issue is that I'm running 3 queries for something that I would like to only have to run one query for. For instance, I want to gather data for leads generated in the past day submission_date > (NOW() - INTERVAL 1 DAY) and I would like to find out how many total leads there were, and how many sold leads there were in that timeframe. (sold=1 / sold=0). The issue comes with the fact that this query is currently being done with 2 queries, one with WHEREsold= 1 and one with WHEREsold= 0. This is all well and good, but when I want to generate this data for the past day,week,month,year,and all time I will have to run 10 queries to obtain this data. I feel like there HAS to be a more efficient way of doing this. I know I can create a mySQL function for this, but I don't see how this could solve the problem. Thanks!!

  • Using Lambda Statements for Event Handlers

    - by lush
    I currently have a page which is declared as follows: public partial class MyPage : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //snip MyButton.Click += (o, i) => { //snip } } } I've only recently moved to .NET 3.5 from 1.1, so I'm used to writing event handlers outside of the Page_Load. My question is; are there any performance drawbacks or pitfalls I should watch out for when using the lambda method for this? I prefer it, as it's certainly more concise, but I do not want to sacrifice performance to use it. Thanks.

  • Java doest run prepare statements with parameter

    - by Zaiman Noris
    If using PreparedStatement to query my table. Unfortunately, I have not been able to do so. My code is as simple as this :- PreparedStatement preparedStatement = connection.prepareStatement( "Select favoritefood from favoritefoods where catname = ?"); preparedStatement.setString(1, "Cappuccino"); ResultSet resultSet = preparedStatement.executeQuery(); Error thrown is java.sql.SQLException: ORA-00911: invalid character. As if it never run through the parameter given. Thanks for your time. I've spend a day to debug this yet still unsuccessful. As mention by Piyush, if I omit the semicolon at the end of statement, new error is thrown. java.sql.SQLException: ORA-00942: table or view does not exist. But I can assure you this table is indeed exist. UPDATE shoot. i edited the wrong sql. now it is successful. thx for your time.

  • conditional while loop in php?

    - by julio
    I'm pretty sure there's an obvious answer for this-- hoping someone can help me-- I need to do a PHP while loop, but only if a variable is true. And I can't really put the while loop in an "if" statement, which seems like the obvious thing to do, since the code block is huge and it would be ugly and confusing. Do I need to break out the code in the loop into a function, or is there an easier way to deal with this? Here's the basic idea: if(condition){ while(another_condition){ //huge block of code loops many times } } else { // huge block of code runs once } I want the huge block of code to execute regardless of the state of the condition variable-- but only to execute once if condition is false, and execute for as long as another_condition is true if condition is true. Hope that's clear! The following code doesn't work, but gives an idea of what I want to accomplish: if(condition){ while(another_condition){ } // huge block of code if (condition){ } } // closes the while loop-- obviously throws an error though! thanks in advance.

  • Nested IF statements in Excel [Over the 7 allowed limit]

    - by Alks
    hey guys, i am trying to create a spreadsheet which automagically gives a grade to a student based on their marks they got. I've apparently hit excels nested IF statement limit which is 7. here's my if statement: =IF(O5>0.895,"A+",IF(O5>0.845,"A",IF(O5>0.795,"A-",IF(O5>0.745,"B+",IF(O5>0.695,"B",IF(O5>0.645,"B-",IF(O5>0.595,"C+",IF(O5>0.545,"C","D")))))))) I was reading online that I could create a VBA script and assign it that, but I dont know anything about VBA....so if someone could help me write a VBA for this, would be awesome. Its still mising the C- grade and anything lower should be awarded a D mark. This is the grading scheme I am trying to create...: A+ 89.500 - 100.000 Pass with Distinction A 84.500 - 89.490 Pass with Distinction A- 79.500 - 84.490 Pass with Distinction B+ 74.500 - 79.490 Pass with Merit B 69.500 - 74.490 Pass with Merit B- 64.500 - 69.490 Pass with Merit C+ 59.500 - 64.490 Pass C 54.500 - 59.490 Pass C- 49.500 - 54.490 Pass D 0.000 - 49.490 Specified Fail I wouldn't mind going down the VBA route, however my understanding of VB language is absolutely minimal (don't like it)...if this gets too tedious, I was thinking to create a small php/mysql application instead. Cheers :)

  • Conditional CellRenderCombo in pyGTK TreeView

    - by Präriewolf
    I have a two column TreeView attached to a ListStore. Both columns are CellRenderCombo combo boxes. When the user selects an entry in the first box, I need to dynamically load a set of options in the second. For example, the behavior I want is: On row 0, the user selects "Alphabet" in the first column box. The second column box is populated with the letters "A-Z". On row 1, the user selects "Numbers" in the first column box. The second column box is populated with the numbers "0-9". On row 2, the user selects "Alphabet" in the first column box. The second column box is populated with the letters "A-Z". etc. Does anyone know how to do this, or seen any open source pygtk or gtk projects that have similar behavior which I can analyze?

  • Only show link if conditional equals true

    I want the link to appear only when $data['block'] equals to 1, 3 or 4.

  • Declaring an object of a conditional type with a System.Type

    - by Chapso
    I am attempting to launch a specific form depending on the selected node of a treeview on the doubleclick event. The code I need to use to launch the form is a little bulky becuase I have to ensure that the form is not disposed, and that the form is not already open, before launching a new instance. I'd like to have all of this checking happen in one place at the end of the function, which means that I have to be able to pass the right form type to the code at the end. I'm trying to do this with a System.Type, but that doesn't seem to be working. Could someone point me in the right direction, please? With TreeView.SelectedNode Dim formType As Type Select Case .Text Case "Email to VPs" formType = EmailForm.GetType() Case "Revise Replacers" formType = DedicatedReplacerForm.GetType() Case "Start Email" formType = EmailForm.GetType() End Select Dim form As formType Dim form As formType Try form = CType(.Tag, formType) If Not form.IsDisposed Then form.Activate() Exit Sub End If Catch ex As NullReferenceException 'This will error out the first time it is run as the form has not yet ' been defined. End Try form = New formType form.MdiParent = Me .Tag = form CType(TreeView.SelectedNode.Tag, Form).Show() End With

  • How to prevent onclick statements from being executed?

    - by ryanli
    I want to use an event listener for preventing the onclick statement of a submit button, however, using event.preventDefault() doesn't work as intended. The code is like this: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="application/x-javascript"> function addListener() { document.getElementById("submit").addEventListener("click", function(ev) { alert("listener"); ev.preventDefault(); }, false); } </script> <title></title> </head> <body onload="addListener();"> <form id="form" method="post" target=""> <input type="submit" id="submit" onclick="alert('onclick')" value="test" /> </form> </body> </html> The expected behaviour is only "listener" will be alerted, but in practice (Firefox 3.7a5pre), "onclick" and "listener" are both alerted, in the given order. It seems that onclick is being executed before the listener, so event.preventDefault() doesn't work. Is there a way to prevent onclick from being executed?

  • MySQL count statements error - operand should contain 1 column(s)

    - by jason
    I am trying to do multiple counts everyone was working accept the first sub select (list1) I get an error that reads "Operand should contain 1 column(s)" i'm guessing it has something to do with the AND, but i'm not sure how I would fix this one. Select Count(list0.ustatus) AS finished_count, (Select list1.ustatus, Count(*) From listofupdates list1 Where list1.ustarted != '0000-00-00 00:00:00' AND list1.ustatus != 1) AS start_count, (Select Count(list2.udifficulty) From listofupdates list2 Where list2.udifficulty = 2) AS recheck_count, (Select Count(list3.udifficulty) From listofupdates list3 Where list3.udifficulty = 4) AS question_count From listofupdates list0 Where list0.ustatus = 1

  • Conditional root_url (index)

    - by vise
    I'd like my application to display different data on the frontpage depending on whether the user has been logged in or not. def index if current_user # render another controllers action else # render another controllers action end end I can achieve this by using render_component. However it has been obsolete for some time. Although I can still use it as a plugin, I'm interested if anyone has a better approach. Just take in mind that rendering another controller's view directly is not an option. Thanks.

  • Conditional WHERE Clauses in SQL Server 2008

    - by user336786
    Hello, I am trying to execute a query on a table in my SQL Server 2008 database. I have a stored procedure that uses five int parameters. Currently, my parameters are defined as follows: @memberType int, @color int, @preference int, @groupNumber int, @departmentNumber int This procedure will be passed -1 or higher for each parameter. A value of -1 means that the WHERE clause should not consider that parameter in the join/clause. If the value of the parameter is greater than -1, I need to consider the value in my WHERE clause. I would prefer to NOT use an IF-ELSE statement because it seems sloppy for this case. I saw this question here. However, it did not work for me. I think the reason why is because each of the columns in my table can have a NULL value. Someone pointed this scenario out in the fifth answer. That appears to be happening to me. Is there a slick approach to my question? Or do I just need to brute force it (I hope not :(). Thank you!

  • Dart Can't get logging statements to compile

    - by Nate Lockwood
    I'm trying to learn how to implement logging using the examples/tutorial in: http://blog.dartwatch.com/2013/05/campaign-to-use-real-logging-instead-of.html#comment-form But having imported the libraries this line in main will not compile because the class 'PrintHandler' is not recognized and Google has not been a help in this case. My server application consists of a main and three classes. I'm new at Dart. Below I've extracted the logging code that I added. In what library is 'PrintHandler'? Is this a class I need to write? library server; import 'package:logging_handlers/logging_handlers_shared.dart'; import 'package:logging/logging.dart'; final _serverLogger = new Logger("server"); // top level logger void main() { Logger.root.onRecord.listen(new PrintHandler()); // default PrintHandler _serverLogger.fine("Server created"); } class A { } class B { } class C { }

  • Conditional PIVOT/transform problem

    - by IanC
    Hi folks I have a table with three columns, which we'll call ID1, ID2, and Value. Sample data: ID ID1 Value 1 1 0 1 2 1 1 3 1 1 3 2 1 4 0 1 4 1 1 5 0 1 5 2 2 1 2 Value is limited to 0, 1, or 2. What I need to do is pivot/transform this data into a column-based count of how many times each possible Value appears, grouped by ID, ID1. The output of the above should be: ID ID1 Val0 Val1 Val2 1 1 1 0 0 1 2 0 2 0 1 3 0 1 1 1 4 1 1 0 1 5 1 0 1 2 1 0 0 1 I'm using SQL Server 2008. How do I do this?

  • How to improve the speed of a loop containing a sqlalchemy query statement as conditional

    - by LtPinback
    This loop checks if a record is in the sqlite database and builds a list of dictionaries for those records that are missing and then executes a multiple insert statement with the list. This works but it is very slow (at least i think it is slow) as it takes 5 minutes to loop over 3500 queries. I am a complete newbie in python, sqlite and sqlalchemy so I wonder if there is a faster way of doing this. list_dict = [] session = Session() for data in data_list: if session.query(Class_object).filter(Class_object.column_name_01 == data[2]).filter(Class_object.column_name_00 == an_id).count() == 0: list_dict.append({'column_name_00':a_id, 'column_name_01':data[2]}) conn = engine.connect() conn.execute(prices.insert(),list_dict) conn.close() session.close() edit: I moved session = Session() outside the loop. Did not make a difference.

  • How to use prepared statements (named parameters) on a php Class

    - by Mohamed Adib Errifai
    This is my first post here. I've searched in the site, but inforutunaly no matchs. Anyway, i want to know how to use named parameters on a class. so the pdo basic form is something like. $query = $bdd->prepare('SELECT * FROM table WHERE login = :login AND pww = :pww'); $query->execute(array('login' => $login, 'pww' => $pww)); and i want to integrate this on a class regardless of the number of parameters. Currently, i have this code http://pastebin.com/kKgSkaKt and for parameters, i use somethings like ( which is wrong and vulnerable to injection ) require_once 'classes/Mysql.class.php'; $mysql = new Mysql(); $sql = 'SELECT * FROM articles WHERE id = '.$_GET['id'].' LIMIT 1'; $data = $mysql->select($sql); And Thanks.

  • MySQL - Conflicting WHERE and GROUP BY Statements

    - by TaylorPLM
    I have a query returning the counts of some data, but I do NOT want data that has a null value in it... As an example, the code rolls stats from a clicking system into a table. SELECT sh.dropid, ... FROM subscriberhistory sh INNER JOIN subscriberhistory sh2 on sh.subid = sh2.subid WHERE sh.dropid IS NOT NULL AND sh.dropid != "" ... GROUP BY sh.dropid An example of the record set returned would look like this... 400 2 3 4 5 6 401 2 3 6 5 4 NULL 2 3 4 5 1 There are some other where clauses, and a few more selects (as I said, using the count aggregate) that are also within the query. There is also an order by statement. Again, the goal is to keep the NULL data out of the preceding record set. Could someone explain to me why this behavior is occurring and what to do to solve it.

  • Quick question regarding Conditional Compilation (ifndef)

    - by sil3nt
    Hello, This is quite probably a very silly question but I need to be sure. I've been given a class declaration in a header file eg. #ifndef file_H #define file_H class ex{ private: public: }; #endif and I've been required to write the method definitions in the same file, which I have done, my question is does the "#endif" stay where it is just after the class declaration or does it go at the end of my file after the class method definitions?.
